3 months later. How the profitability of mining changed after halving
On May 11, the size of the Bitcoin mining reward fell by half. The next time it will be in 2024. What devices will be profitable by that time, and what to hope for owners of obsolete equipment.
In May 2020, a halving took place on the bitcoin network. The cryptocurrency mining reward has decreased from 12.5 to 6.25 BTC. This is a long-awaited event, which, according to the hopes of the crypto community, should lead to a strong increase in the value of the coin. For example, Anthony Pompliano, co-founder of investment company Morgan Creek Digital, predicted that the rate would rise to $100,000 by the end of 2021, primarily due to lower mining rewards.
So far, the bitcoin price hasn’t responded to the halving as much as expected. In mid-May, at the time of the reduction in the mining reward, the BTC rate was around $9,000. To date, the cryptocurrency has risen in price by 27%. This year’s high was set yesterday, August 18, at $12,400.
The hashrate of the cryptocurrency network showed a different dynamics. Its value fell immediately after the halving from 137.5 to 87 EH/s, according to bitinfocharts.com. Since mining bitcoins has become less profitable, some of the miners probably turned off their equipment. They could switch to mining other coins or completely abandon this activity due to its unprofitability.
Later, when the BTC rate began to rise, the amount of computing power in the coin’s network also began to increase. So, from late May to mid-August, the cryptocurrency hash rate increased from 87 to 130 EH/s. But over the past three days, the figure has dropped sharply by 20%, caused by floods in China. Torrential rains in Sichuan province caused power outages that interfered with the operation of mining farms.
Changes in hashrate and mining rewards have affected its difficulty. On May 11, at the time of the halving, this figure was at around 16.1 T. By the current moment, this value has increased to 16.9 T, in July rising to a maximum of 17.3 T.
The decline in the reward for mining cryptocurrency was partially offset by the increase in fees. Until May, a single BTC transfer cost the user an average of 50 cents. By the current moment, commissions have grown more than 10 times, to $5.5.
Mining profitability is now at around 0.114 THash/s. It fell sharply immediately after the halving from 0.16 to 0.08 THash/s. To date, the indicator has grown by 40%. This was due to the rise in BTC prices and higher fees.
Development Director at BitCluster Dmitry Shuvaev said that the profitability of the device for mining BTC s17–73Th/s is now about 8 thousand rubles per month (at an electricity price of 3.5 rubles per kWh). The payback period is about 15 months. Old devices, such as the Antminer S9, are now unprofitable to use, they do not bring profit. But this situation may change if the bitcoin rate rises to $15,000.
“We recommend our customers to buy the new generation S17 or S19 devices. It is these devices that will provide profitability until the next halving. Their break-even point is at $6,000 per bitcoin”, Shuvaev said.
In June, specialists from the research division of the BitMEX exchange announced that in the long term, 2–3 ASIC miner manufacturers will remain in the industry. Canaan’s Avalon devices were the first to hit the market in 2014. Three years later, in 2017, Bitmain took 75% of the market.

Transcript of discussion between an ASIC designer and several proof-of-work designers from #monero-pow channel on Freenode this morning

[08:07:01] lukminer contains precompiled cn/r math sequences for some blocks: https://lukminer.org/2019/03/09/oh-kay-v4r-here-we-come/
[08:07:11] try that with RandomX :P
[08:09:00] tevador: are you ready for some RandomX feedback? it looks like the CNv4 is slowly stabilizing, hashrate comes down...
[08:09:07] how does it even make sense to precompile it?
[08:09:14] mine 1% faster for 2 minutes?
[08:09:35] naturally we think the entire asic-resistance strategy is doomed to fail :) but that's a high-level thing, who knows. people may think it's great.
[08:09:49] about RandomX: looks like the cache size was chosen to make it GPU-hard
[08:09:56] looking forward to more docs
[08:11:38] after initial skimming, I would think it's possible to make a 10x asic for RandomX. But at least for us, we will only make an ASIC if there is not a total ASIC hostility there in the first place. That's better for the secret miners then.
[08:13:12] What I propose is this: we are working on an Ethash ASIC right now, and once we have that working, we would invite tevador or whoever wants to come to HK/Shenzhen and we walk you guys through how we would make a RandomX ASIC. You can then process this input in any way you like. Something like that.
[08:13:49] unless asics (or other accelerators) re-emerge on XMR faster than expected, it looks like there is a little bit of time before RandomX rollout
[08:14:22] 10x in what measure? $/hash or watt/hash?
[08:14:46] watt/hash
[08:15:19] so you can make 10 times more efficient double precisio FPU?
[08:16:02] like I said let's try to be productive. You are having me here, let's work together!
[08:16:15] continue with RandomX, publish more docs. that's always helpful.
[08:16:37] I'm trying to understand how it's possible at all. Why AMD/Intel are so inefficient at running FP calculations?
[08:18:05] midipoet ([email protected]/web/irccloud.com/x-vszshqqxwybvtsjm) has joined #monero-pow
[08:18:17] hardware development works the other way round. We start with 1) math then 2) optimization priority 3) hw/sw boundary 4) IP selection 5) physical implementation
[08:22:32] This still doesn't explain at which point you get 10x
[08:23:07] Weren't you the ones claiming "We can accelerate ProgPoW by a factor of 3x to 8x." ? I find it hard to believe too.
[08:30:20] sure
[08:30:26] so my idea: first we finish our current chip
[08:30:35] from simulation to silicon :)
[08:30:40] we love this stuff... we do it anyway
[08:30:59] now we have a communication channel, and we don't call each other names immediately anymore: big progress!
[08:31:06] you know, we russians have a saying "it was smooth on paper, but they forgot about ravines"
[08:31:12] So I need a bit more details
[08:31:16] ha ha. good!
[08:31:31] that's why I want to avoid to just make claims
[08:31:34] let's work
[08:31:40] RandomX comes in Sep/Oct, right?
[08:31:45] Maybe
[08:32:20] We need to audit it first
[08:32:31] ok
[08:32:59] we don't make chips to prove sw devs that their assumptions about hardware are wrong. especially not if these guys then promptly hardfork and move to the next wrong assumption :)
[08:33:10] from the outside, this only means that hw & sw are devaluing each other
[08:33:24] neither of us should do this
[08:33:47] we are making chips that can hopefully accelerate more crypto ops in the future
[08:33:52] signing, verifying, proving, etc.
[08:34:02] PoW is just a feature like others
[08:34:18] sech1: is it easy for you to come to Hong Kong? (visa-wise)
[08:34:20] or difficult?
[08:34:33] or are you there sometimes?
[08:34:41] It's kind of far away
[08:35:13] we are looking forward to more RandomX docs. that's the first step.
[08:35:31] I want to avoid that we have some meme "Linzhi says they can accelerate XYZ by factor x" .... "ha ha ha"
[08:35:37] right? we don't want that :)
[08:35:39] doc is almost finished
[08:35:40] What docs do you need? It's described pretty good
[08:35:41] so I better say nothing now
[08:35:50] we focus on our Ethash chip
[08:36:05] then based on that, we are happy to walk interested people through the design and what else it can do
[08:36:22] that's a better approach from my view than making claims that are laughed away (rightfully so, because no silicon...)
[08:36:37] ethash ASIC is basically a glorified memory controller
[08:36:39] sech1: tevador said something more is coming (he just did it again)
[08:37:03] yes, some parts of RandomX are not described well
[08:37:10] like dataset access logic
[08:37:37] RandomX looks like progpow for CPU
[08:37:54] yes
[08:38:03] it is designed to reflect CPU
[08:38:34] so any ASIC for it = CPU in essence
[08:39:04] of course there are still some things in regular CPU that can be thrown away for RandomX
[08:40:20] uncore parts are not used, but those will use very little power
[08:40:37] except for memory controller
[08:41:09] I'm just surprised sometimes, ok? let me ask: have you designed or taped out an asic before? isn't it risky to make assumptions about things that are largely unknown?
[08:41:23] I would worry
[08:41:31] that I get something wrong...
[08:41:44] but I also worry like crazy that CNv4 will blow up, where you guys seem to be relaxed
[08:42:06] I didn't want to bring up anything RandomX because CNv4 is such a nailbiter... :)
[08:42:15] how do you guys know you don't have asics in a week or two?
[08:42:38] we don't have experience with ASIC design, but RandomX is simply designed to exactly fit CPU capabilities, which is the best you can do anyways
[08:43:09] similar as ProgPoW did with GPUs
[08:43:14] some people say they want to do asic-resistance only until the vast majority of coins has been issued
[08:43:21] that's at least reasonable
[08:43:43] yeah but progpow totally will not work as advertised :)
[08:44:08] yeah, I've seen that comment about progpow a few times already
[08:44:11] which is no surprise if you know it's just a random sales story to sell a few more GPUs
[08:44:13] RandomX is not permanent, we are expecting to switch to ASIC friendly in a few years if possible
[08:44:18] yes
[08:44:21] that makes sense
[08:44:40] linzhi-sonia: how so? will it break or will it be asic-able with decent performance gains?
[08:44:41] are you happy with CNv4 so far?
[08:45:10] ah, long story. progpow is a masterpiece of deception, let's not get into it here.
[08:45:21] if you know chip marketing it makes more sense
[08:45:24] linzhi-sonia: So far? lol! a bit early to tell, don't you think?
[08:45:35] the diff is coming down
[08:45:41] first few hours looked scary
[08:45:43] I remain skeptical: I only see ASICs being reasonable if they are already as ubiquitous as smartphones
[08:45:46] yes, so far so good
[08:46:01] we kbew the diff would not come down ubtil affter block 75
[08:46:10] yes
[08:46:22] but first few hours it looks like only 5% hashrate left
[08:46:27] looked
[08:46:29] now it's better
[08:46:51] the next worry is: when will "unexplainable" hashrate come back?
[08:47:00] you hope 2-3 months? more?
[08:47:05] so give it another couple of days. will probably overshoot to the downside, and then rise a bit as miners get updated and return
[08:47:22] 3 months minimum turnaround, yes
[08:47:28] nah
[08:47:36] don't underestimate asicmakers :)
[08:47:54] you guys don't get #1 priority on chip fabs
[08:47:56] 3 months = 90 days. do you know what is happening in those 90 days exactly? I'm pretty sure you don't. same thing as before.
[08:48:13] we don't do any secret chips btw
[08:48:21] 3 months assumes they had a complete design ready to go, and added the last minute change in 1 day
[08:48:24] do you know who is behind the hashrate that is now bricked?
[08:48:27] innosilicon?
[08:48:34] hyc: no no, and no. :)
[08:48:44] hyc: have you designed or taped out a chip before?
[08:48:51] yes, many years ago
[08:49:10] then you should know that 90 days is not a fixed number
[08:49:35] sure, but like I said, other makers have greater demand
[08:49:35] especially not if you can prepare, if you just have to modify something, or you have more programmability in the chip than some people assume
[08:50:07] we are chipmakers, we would never dare to do what you guys are doing with CNv4 :) but maybe that just means you are cooler!
[08:50:07] and yes, programmability makes some aspect of turnaround easier
[08:50:10] all fine
[08:50:10] I hope it works!
[08:50:28] do you know who is behind the hashrate that is now bricked?
[08:50:29] inno?
[08:50:41] we suspect so, but have no evidence
[08:50:44] maybe we can try to find them, but we cannot spend too much time on this
[08:50:53] it's probably not so much of a secret
[08:51:01] why should it be, right?
[08:51:10] devs want this cat-and-mouse game? devs get it...
[08:51:35] there was one leak saying it's innosilicon
[08:51:36] so you think 3 months, ok
[08:51:43] inno is cool
[08:51:46] good team
[08:51:49] IP design house
[08:51:54] in Wuhan
[08:52:06] they send their people to conferences with fake biz cards :)
[08:52:19] pretending to be other companies?
[08:52:26] sure
[08:52:28] ha ha
[08:52:39] so when we see them, we look at whatever card they carry and laugh :)
[08:52:52] they are perfectly suited for secret mining games
[08:52:59] they made at most $6 million in 2 months of mining, so I wonder if it was worth it
[08:53:10] yeah. no way to know
[08:53:15] but it's good that you calculate!
[08:53:24] this is all about cost/benefit
[08:53:25] then you also understand - imagine the value of XMR goes up 5x, 10x
[08:53:34] that whole "asic resistance" thing will come down like a house of cards
[08:53:41] I would imagine they sell immediately
[08:53:53] the investor may fully understand the risk
[08:53:57] the buyer
[08:54:13] it's not healthy, but that's another discussion
[08:54:23] so mid-June
[08:54:27] let's see
[08:54:49] I would be susprised if CNv4 ASICs show up at all
[08:54:56] surprised*
[08:54:56] why?
[08:55:05] is only an economic question
[08:55:12] yeah should be interesting. FPGAs will be near their limits as well
[08:55:16] unless XMR goes up a lot
[08:55:19] no, not *only*. it's also a technology question
[08:55:44] you believe CNv4 is "asic resistant"? which feature?
[08:55:53] it's not
[08:55:59] cnv4 = Rabdomx ?
[08:56:03] no
[08:56:07] cnv4=cryptinight/r
[08:56:11] ah
[08:56:18] CNv4 is the one we have now, I think
[08:56:21] since yesterday
[08:56:30] it's plenty enough resistant for current XMR price
[08:56:45] that may be, yes!
[08:56:55] I look at daily payouts. XMR = ca. 100k USD / day
[08:57:03] it can hold until October, but it's not asic resistant
[08:57:23] well, last 24h only 22,442 USD :)
[08:57:32] I think 80 h/s per watt ASICs are possible for CNv4
[08:57:38] linzhi-sonia where do you produce your chips? TSMC?
[08:57:44] I'm cruious how you would expect to build a randomX ASIC that outperforms ARM cores for efficiency, or Intel cores for raw speed
[08:57:48] curious
[08:58:01] yes, tsmc
[08:58:21] Our team did the world's first bitcoin asic, Avalon
[08:58:25] and upcoming 2nd gen Ryzens (64-core EPYC) will be a blast at RandomX
[08:58:28] designed and manufactured
[08:58:53] still being marketed?
[08:59:03] linzhi-sonia: do you understand what xmr wants to achieve, community-wise?
[08:59:14] Avalon? as part of Canaan Creative, yes I think so.
[08:59:25] there's not much interesting oing on in SHA256
[08:59:29] Inge-: I would think so, but please speak
[08:59:32] hyc: yes
[09:00:28] linzhi-sonia: i am curious to hear your thoughts. I am fairly new to this space myself...
[09:00:51] oh
[09:00:56] we are grandpas, and grandmas
[09:01:36] yet I have no problem understanding why ASICS are currently reviled.
[09:01:48] xmr's main differentiators to, let's say btc, are anonymity and fungibility
[09:01:58] I find the client terribly slow btw
[09:02:21] and I think the asic-forking since last may is wrong, doesn't create value and doesn't help with the project objectives
[09:02:25] which "the client" ?
[09:02:52] Monero GUI client maybe
[09:03:12] MacOS, yes
[09:03:28] What exactly is slow?
[09:03:30] linzhi-sonia: I run my own node, and use the CLI and Monerujo. Have not had issues.
[09:03:49] staying in sync
[09:03:49] linzhi-sonia: decentralization is also a key principle
[09:03:56] one that Bitcoin has failed to maintain
[09:04:39] hmm
[09:05:00] looks fairly decentralized to me. decentralization is the result of 3 goals imo: resilient, trustless, permissionless
[09:05:28] don't ask a hardware maker about physical decentralization. that's too ideological. we focus on logical decentralization.
[09:06:11] physical decentralization is important. with bulk of bitnoin mining centered on Chinese hydroelectric dams
[09:06:19] have you thought about including block data in the PoW?
[09:06:41] yes, of course.
[09:07:39] is that already in an algo?
[09:08:10] hyc: about "centered on chinese hydro" - what is your source? the best paper I know is this: https://coinshares.co.uk/wp-content/uploads/2018/11/Mining-Whitepaper-Final.pdf
[09:09:01] linzhi-sonia: do you mine on your ASICs before you sell them?
[09:09:13] besides testing of course
[09:09:45] that paper puts Chinese btc miners at 60% max
[09:10:05] tevador: I think everybody learned that that is not healthy long-term!
[09:10:16] because it gives the chipmaker a cost advantage over its own customers
[09:10:33] and cost advantage leads to centralization (physical and logical)
[09:10:51] you guys should know who finances progpow and why :)
[09:11:05] but let's not get into this, ha ha. want to keep the channel civilized. right OhGodAGirl ? :)
[09:11:34] tevador: so the answer is no! 100% and definitely no
[09:11:54] that "self-mining" disease was one of the problems we have now with asics, and their bad reputation (rightfully so)
[09:13:08] I plan to write a nice short 2-page paper or so on our chip design process. maybe it's interesting to some people here.
[09:13:15] basically the 5 steps I mentioned before, from math to physical
[09:13:32] linzhi-sonia: the paper you linked puts 48% of bitcoin mining in Sichuan. the total in China is much more than 60%
[09:13:38] need to run it by a few people to fix bugs, will post it here when published
[09:14:06] hyc: ok! I am just sharing the "best" document I know today. it definitely may be wrong and there may be a better one now.
[09:14:18] hyc: if you see some reports, please share
[09:14:51] hey I am really curious about this: where is a PoW algo that puts block data into the PoW?
[09:15:02] the previous paper I read is from here http://hackingdistributed.com/2018/01/15/decentralization-bitcoin-ethereum/
[09:15:38] hyc: you said that already exists? (block data in PoW)
[09:15:45] it would make verification harder
[09:15:49] linzhi-sonia: https://the-eye.eu/public/Books/campdivision.com/PDF/Computers%20General/Privacy/bitcoin/meh/hashimoto.pdf
[09:15:51] but for chips it would be interesting
[09:15:52] we discussed the possibility about a year ago https://www.reddit.com/Monero/comments/8bshrx/what_we_need_to_know_about_proof_of_work_pow/
[09:16:05] oh good links! thanks! need to read...
[09:16:06] I think that paper by dryja was original
[09:17:53] since we have a nice flow - second question I'm very curious about: has anyone thought about in-protocol rewards for other functions?
[09:18:55] we've discussed micropayments for wallets to use remote nodes
[09:18:55] you know there is a lot of work in other coins about STARK provers, zero-knowledge, etc. many of those things very compute intense, or need to be outsourced to a service (zether). For chipmakers, in-protocol rewards create an economic incentive to accelerate those things.
[09:19:50] whenever there is an in-protocol reward, you may get the power of ASICs doing something you actually want to happen
[09:19:52] it would be nice if there was some economic reward for running a fullnode, but no one has come up with much more than that afaik
[09:19:54] instead of fighting them off
[09:20:29] you need to use asics, not fight them. that's an obvious thing to say for an asicmaker...
[09:20:41] in-protocol rewards can be very powerful
[09:20:50] like I said before - unless the ASICs are so useful they're embedded in every smartphone, I dont see them being a positive for decentralization
[09:21:17] if they're a separate product, the average consumer is not going to buy them
[09:21:20] now I was talking about speedup of verifying, signing, proving, etc.
[09:21:23] they won't even know what they are
[09:22:07] if anybody wants to talk about or design in-protocol rewards, please come talk to us
[09:22:08] the average consumer also doesn't use general purpose hardware to secure blockchains either
[09:22:14] not just for PoW, in fact *NOT* for PoW
[09:22:32] it requires sw/hw co-design
[09:23:10] we are in long-term discussions/collaboration over this with Ethereum, Bitcoin Cash. just talk right now.
[09:23:16] this was recently published though suggesting more uptake though I guess https://btcmanager.com/college-students-are-the-second-biggest-miners-of-cryptocurrency/
[09:23:29] I find it pretty hard to believe their numbers
[09:24:03] well
[09:24:09] sorry, original article: https://www.pcmag.com/news/366952/college-kids-are-using-campus-electricity-to-mine-crypto
[09:24:11] just talk, no? rumors
[09:24:18] college students are already more educated than the average consumer
[09:24:29] we are not seeing many such customers anymore
[09:24:30] it's data from cisco monitoring network traffic
[09:24:33] and they're always looking for free money
[09:24:48] of course anyone with "free" electricity is inclined to do it
[09:24:57] but look at the rates, cannot make much money
[09:26:06] Ethereum is a bloated collection of bugs wrapped in a UI. I suppose they need all the help they can get
[09:26:29] Bitcoin Cash ... just another get rich quick scheme
[09:26:38] hmm :)
[09:26:51] I'll give it back to you, ok? ha ha. arrogance comes before the fall...
[09:27:17] maye we should have a little fun with CNv4 mining :)
[09:27:25] ;)
[09:27:38] come on. anyone who has watched their track record... $75M lost in ETH at DAO hack
[09:27:50] every smart contract that comes along is just waiting for another hack
[09:27:58] I just wanted to throw out the "in-protocol reward" thing, maybe someone sees the idea and wants to cowork. maybe not. maybe it's a stupid idea.
[09:29:18] linzhi-sonia: any thoughts on CN-GPU?
[09:29:55] CN-GPU has one positive aspect - it wastes chip area to implement all 18 hash algorithms
[09:30:19] you will always hear roughly the same feedback from me:
[09:30:52] "This algorithm very different, it heavy use floating point operations to hurt FPGAs and general purpose CPUs"
[09:30:56] the problem is, if it's profitable for people to buy ASIC miners and mine, it's always more profitable for the manufacturer to not sell and mine themselves
[09:31:02] "hurt"
[09:31:07] what is the point of this?
[09:31:15] it totally doesn't work
[09:31:24] you are hurting noone, just demonstrating lack of ability to think
[09:31:41] what is better: algo designed for chip, or chip designed for algo?
[09:31:43] fireice does it on daily basis, CN-GPU is a joke
[09:31:53] tevador: that's not really true, especially in a market with such large price fluctuations as cryptocurrency
[09:32:12] it's far less risky to sell miners than mine with them and pray that price doesn't crash for next six months
[09:32:14] I think it's great that crypto has a nice group of asicmakers now, hw & sw will cowork well
[09:32:36] jwinterm yes, that's why they premine them and sell after
[09:32:41] PoW is about being thermodynamically and cryptographically provable
[09:32:45] premining with them is taking on that risk
[09:32:49] not "fork when we think there are asics"
[09:32:51] business is about risk minimization
[09:32:54] that's just fear-driven
[09:33:05] Inge-: that's roughly the feedback
[09:33:24] I'm not saying it hasn't happened, but I think it's not so simple as saying "it always happens"
[09:34:00] jwinterm: it has certainly happened on BTC. and also on XMR.
[09:34:19] ironically, please think about it: these kinds of algos indeed prove the limits of the chips they were designed for. but they don't prove that you cannot implement the same algo differently! cannot!
[09:34:26] Risk minimization is not starting a business at all.
[09:34:34] proof-of-gpu-limit. proof-of-cpu-limit.
[09:34:37] imagine you have a money printing machine, would you sell it?
[09:34:39] proves nothing for an ASIC :)
[09:35:05] linzhi-sonia: thanks. I dont think anyone believes you can't make a more efficient cn-gpu asic than a gpu - but that it would not be orders of magnitude faster...
[09:35:24] ok
[09:35:44] like I say. these algos are, that's really ironic, designed to prove the limitatios of a particular chip in mind of the designer
[09:35:50] exactly the wrong way round :)
[09:36:16] like the cache size in RandomX :)
[09:36:18] beautiful
[09:36:29] someone looked at GPU designs
[09:37:31] linzhi-sonia can you elaborate? Cache size in RandomX was selected to fit CPU cache
[09:37:52] yes
[09:38:03] too large for GPU
[09:38:11] as I said, we are designing the algorithm to exactly fit CPU capabilities, I do not claim an ASIC cannot be more efficient
[09:38:16] ok!
[09:38:29] when will you do the audit?
[09:38:35] will the results be published in a document or so?
[09:38:37] I claim that single-chip ASIC is not viable, though
[09:39:06] you guys are brave, noone disputes that. 3 anti-asic hardforks now!
[09:39:18] 4th one coming
[09:39:31] 3 forks were done not only for this
[09:39:38] they had scheduled updates in the first place
[09:48:10] Monero is the #1 anti-asic fighter
[09:48:25] Monero is #1 for a lot of reasons ;)
[09:48:40] It's the coin with the most hycs.
[09:48:55] mooooo
[09:59:06] sneaky integer overflow, bug squished
[10:38:00] p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has joined #monero-pow
[11:10:53] The convo here is wild
[11:12:29] it's like geo-politics at the intersection of software and hardware manufacturing for thermoeconomic value.
[11:13:05] ..and on a Sunday.
[11:15:43] midipoet: hw and sw should work together and stop silly games to devalue each other. to outsiders this is totally not attractive.
[11:16:07] I appreciate the positive energy here to try to listen, learn, understand.
[11:16:10] that's a start
[11:16:48] <-- p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has quit (Quit: Leaving)
[11:16:54] we won't do silly mining against xmr "community" wishes, but not because we couldn'd do it, but because it's the wrong direction in the long run, for both sides
[11:18:57] linzhi-sonia: I agree to some extent. Though, in reality, there will always be divergence between social worlds. Not every body has the same vision of the future. Reaching societal consensus on reality tomorrow is not always easy
[11:20:25] absolutely. especially at a time when there is so much profit to be made from divisiveness.
[11:20:37] someone will want to make that profit, for sure
[11:24:32] Yes. Money distorts.
[11:24:47] Or wealth...one of the two
[11:26:35] Too much physical money will distort rays of light passing close to it indeed.

Bitcoin Mining Profitability: How Long Does it Take to Mine One Bitcoin in 2019?

When it comes to Bitcoin (BTC) mining, the major questions on people’s minds are “how profitable is Bitcoin mining” and “how long would it take to mine one Bitcoin?” To answer these questions, we need to take an in-depth look at the current state of the Bitcoin mining industry — and how it has changed — over the last several years.
Bitcoin mining is, essentially, the process of participating in Bitcoin’s underlying security mechanism — known as proof-of-work — to help secure the Bitcoin blockchain. In return, participants receive compensation in bitcoins (BTC).
When you participate in Bitcoin mining, you are essentially searching for blocks by crunching complex cryptographic challenges using your mining hardware. Once a block is discovered, new transactions are recorded and verified within the block and the block discoverer receives the block rewards — currently set at 12.5 BTC — as well as the transactions fees for the transactions included within the block.
Once the maximum supply of 21 million Bitcoins has been mined, no further Bitcoins will ever come into existence. This property makes Bitcoin deflationary, something which many argue will inevitably increase the value of each Bitcoin unit as it becomes more scarce due to increased global adoption.
The limited supply of Bitcoin is also one of the reasons why Bitcoin mining has become so popular. In previous years, Bitcoin mining proved to be a lucrative investment option — netting miners with several fold returns on their investment with relatively little effort.
bitcoin mining hardware
Mining Hardware
The mining hardware you choose will mostly depend on your circumstances — in terms of budget, location and electricity costs. Since the amount of hashing power you can dedicate to the mining process is directly correlated with how much Bitcoin you will mine per day, it is wise to ensure your hardware is still competitive in 2019.
Bitcoin uses SHA256 as its mining algorithm. Because of this, only hardware compatible with this algorithm can be used to mine Bitcoin. Although it is technically possible to mine Bitcoin on your current computer hardware — using your CPU or GPU — this will almost certainly not generate a positive return on your investment and you may end up damaging your device.
The most cost-effective way to mine Bitcoin in 2019 is using application-specific integrated circuit (ASIC) mining hardware. These are specially-designed machines that offer much higher performance per watt than typical computers and have been an absolutely essential purchase for anybody looking to get into Bitcoin mining since the first Avalon ASICs were shipped in 2013.
When it comes to selecting Bitcoin mining hardware, there are several main parameters to consider — though the importance of each of these may vary based on personal circumstances and budget.
Performance per Watt
When it comes to Bitcoin mining, performance per watt is a measure of how many gigahashes per watt a machine is capable of and is, hence, a simple measure of its efficiency. Since electricity costs are likely to be one of the largest expenses when mining Bitcoin, it is usually a good idea to ensure that you are getting good performance per watt out of your hardware.
Ideally, your mining hardware would be highly efficient, allowing it to mine Bitcoin with lower energy requirements — though this will need to be balanced with acquisition costs, as often the most efficient hardware is also the most expensive. This means it may take longer to see a return on investment.
In countries with cheap electricity, performance per watt is often less of a concern than acquisition costs and price-performance ratio. In most countries, operating outdated mining hardware is typically cost prohibitive, as energy costs outweigh the income generated by the mining equipment.
However, this may not be the case for those operating in countries with extremely cheap electricity — such as Kuwait and Venezuela — as even older equipment can still be profitable. Similarly, miners with a free energy surplus, such as from wind or solar electric generators, can benefit from the minimal gains offered by still running outdated hardware.
Longevity
The lifetime of mining hardware also plays a critical role in determining how profitable your mining venture will be. It’s always a good idea to do whatever possible to ensure it runs as smoothly as possible.
Since mining equipment tends to run at a full (or almost full) load for extended periods, they also tend to break down and fail more frequently than most electronics — which can seriously damage your profitability. Equipment failure is even more common when purchasing second-hand equipment. Since warranty claims are often challenging, it can often take a long time to receive a warranty replacement.
Price-Performance Ratio
In many cases, one of the major criteria used to select mining hardware is the price-performance ratio — a measure of how much performance a machine outputs per unit price. In the case of cryptocurrency mining hardware, this is commonly expressed as gigahashes per dollar or GH/$.
Under ideal circumstances, the mining hardware would have a high price-performance ratio, ensuring you get a lot of bang for your buck. However, this must also be considered in combination with the acquisition costs and the expected lifetime of the machine — since the absolute most powerful machines are not always the cheapest or the most energy efficient.
Acquisition Costs
Acquisition costs are almost always the biggest barrier to entry for most Bitcoin miners since most top-end mining hardware costs several thousand dollars. This problem is further compounded by the fact that many hardware manufacturers offer discounts for bulk purchases, allowing those with deeper pockets to achieve a better price-performance ratio.
Acquisition costs include all the costs involved in purchasing any mining equipment, including hardware costs, shipping costs, import duties, and any further costs. For example, many ASIC miners do not include a power supply — which can be another considerable expense, since the 1,000W+ power supplies usually required tend to cost several hundred dollars alone.
Ensuring your equipment runs smoothly can also add in additional costs, such as cooling and maintenance expenses. In addition, some miners may want to invest in uninterruptible power supplies to ensure their hardware keeps running — even if the power fails temporarily.
asic mining
Current Generation Hardware
One of the most recent additions to the Bitcoin mining hardware market is the Ebang Ebit E11++, which was released in October 2018. Using a 10nm fabrication process for its processors, the Ebit E11++ is able to achieve one of the highest hash rates on the market at 44TH/s.
In terms of efficiency, the Ebang Ebit E11++ is arguably the best on the market, offering 44TH/s of hash rate while drawing just 1,980W of power, offering 22.2GH/W performance. However, as of writing, the Ebang Ebit E11++ is out of stock until March 31, 2019 — while its price of $2,024 (excluding shipping) may make it prohibitively expensive for those first getting involved with Bitcoin mining.
Another popular choice is the ASICminer 8 Nano, a machine released in October 2018 that offers 44TH/s for $3,900 excluding shipping. The ASICminer 8 Nano draws 2,100W of power, giving it an efficiency of almost 21GH/W — slightly lower than the Ebit E11++ while costing almost double the price. However, unlike the E11++, the 8 Nano is actually in stock and available to purchase.
ASICminer also offers the 8 Nano Pro, a machine launched in mid-2018 that offers 80 TH/s of hash rate for $9,500 (excluding shipping). However, unlike the Ebit E11++ and 8 Nano, the minimum order quantity for the 8 Nano Pro is curiously set at five, meaning you will need to lay out a minimum of $47,500 in order to actually get your hands on one (or five).
While the 8 Nano Pro doesn’t offer the same performance per watt as the Ebit E11+ or AICMiner 8 Nano, it is one of the quieter miners on this list, making it more suitable for a home or office environment. That being said, the ASICminer 8 Nano Pro is easily the most expensive miner per TH on this list — costing a whopping $118.75/TH, compared to the $46/TH offered by the E11++ and $88.64 offered by the 8 Nano.
The latest hardware on this list is the Innosilicon T3 43T, which is currently available for pre-order at $2,279, and estimated to ship in March 2019. Offering 43TH/s of performance at 2,100W, the T3 43T comes in at an efficiency of 20.4GH/W, which is around 10 percent less energy efficient than the Ebit E11++.
The T3 43T also has a minimum order quantity of three units, making the minimum acquisition cost $6837 + shipping for preorders. All in all, the T3 43T is more costly and less efficient than the E11++ but may arrive slightly earlier since Ebang will not ship the E11++ units until at least end March 29, 2019.
Finally, this list would not be complete without including Bitmain’s latest offering, the Antminer S15-28TH/s, which — as its name suggests — offers 28TH/s of hash power while drawing just under 1600W at the wall. The Antminer S15 is one of the only SHA256 miners to use 7nm processors, making it somewhat smaller than some of the other devices on this list.
Like most pieces of top-end Bitcoin mining hardware, the Antminer S15 27TH/s model is currently sold out, with current orders not shipping until mid-February 2019. However, the S15 is offered at a significantly lower price than many of its competitors at just $1020 (excluding shipping), with no minimum quantity restriction. At these rates, the Antminer comes in at just $37.78/TH — though its energy efficiency is a much less impressive 17.5GH/W.

How To Select a Good Mining Pool
Mining pools are platforms that allow miners to pool their resources together to achieve a higher collective hash rate — which, in turn, allows the collective to mine more blocks than they would be able to achieve alone.
Typically, these mining pools will distribute block rewards to contributing miners based on the proportion of the hash rate they supply. If a pool contributing a total of 20 TH/s of hash rate successfully mines the next block, a user responsible for 10 percent of this hash rate will receive 10 percent of the 12.5 BTC reward.
Pools essentially allow smaller miners to compete with large private mining organizations by ensuring that the collective hash rate is high enough to successfully mine blocks on regular basis. Without operating through a mining pool, many miners would be unlikely to discover any blocks at all — due to only contributing a tiny fraction of the overall Bitcoin hash rate.
While it is quite possible to be successful mining without a pool, this typically requires an extremely large mining operation and is usually not recommended — unless you have enough hash rate to mine blocks on a regular basis.
Although it is technically possible to discover blocks mining solo and keep the entire 12.5 BTC reward for yourself, the odds of this actually occurring are practically zero — making pool collaboration practically the only way to compete in 2019 and beyond.
Selecting the best pool for you can be a challenging job since the vast majority of pools are quite similar and offer similar features and comparable fees. Because of this, we have broken down the qualities you should be looking for in a new pool into four categories; reputation, hash rate, pool fees, and usability/features:
Reputation
The reputation of a pool is one of the most important factors in selecting the pool that is best for you. Well-reputed pools will tend to be much larger than newer or less well-established pools since few pools with a poor reputation can stand the test of time.
Well-reputed pools also tend to be more transparent about their operation, many of which provide tools to ensure that each user is getting the correct reward based on the hash rate contributed. By using only pools with a great reputation, you also ensure your hash rate is not being used for nefarious purposes — such as powering a 51 percent attack.
When comparing a list of pools that appear suitable for you, it is a wise move to read their user reviews before making your choice — ensuring you don’t end up mining at a pool that steals your hard-fought earnings.
Hash Rate
When it comes to mining Bitcoin, the probability of discovering the next block is directly related to the amount of hashing power you contribute to the network. Because of this, one of the major features you should be considering when selecting your pool is its total hash rate — which is often closely related to the proportion of new blocks mined by the pool
Since the total hash rate of a pool is directly related to how quickly it discovers new blocks, this means the largest pools tend to discover a relative majority of blocks — leading to more regular rewards. However, the very largest pools also tend the have higher fees but often make up for this with sheer success and additional features.
Sometimes, some of the largest pools have a minimum hash rate requirement ù leaving some of the smaller miners left out of the loop. Although smaller pools typically have more relaxed requirements with reduced performance thresholds, these pools may be only slightly more profitable than mining solo.
Pool Fees
When choosing a suitable pool, typically one of the major considerations is its fees. Typically, most pools will charge a small fee that is deducted from your earnings and is usually around 1-2 percent — but sometimes slightly lower or higher.
There are also pools that offer 0 percent fees. However, these are often much smaller than the major pools and tend to make their money in a different way — such as through monthly subscriptions or donations.
Ideally, you will choose the pool that offers the best balance of fees to other features. Usually, the pool with the absolute lowest fees is not the best choice. Additionally, pools with the lowest fees often have the highest withdrawal minimums — making pool hopping uneconomical for most.
Usability and Features
When first starting out with Bitcoin mining, learning how to set up a pool and navigating through the settings can be a challenge. Because of this, several pools target their services to newer users by offering a simple to navigate user interface and providing detailed learning resources and prompt customer support.
However, for more experienced miners, simple pools don’t tend to offer a variety of features needed to maximize profitability. For example, although many mining pools focus their entire hash rate towards mining a single cryptocurrency, some are large enough to offer additional options — allowing users to mine other SHA256 coins such as Bitcoin Cash (BCH) or Fantom if they choose.
These pools are technically more challenging to use and mostly designed for those familiar with mining, happy to hop from coin to coin mining whichever is most profitable at the time. There are even some exchanges that automatically direct their combined hash rate at the most profitable cryptocurrency — taking the guesswork out of the equation.

Best Mining Pools for 2019
The Bitcoin mining pool industry has a large number of players, but the vast majority of the Bitcoin hash rate is concentrated within just a few pools. Currently, there are dozens of suitable pools to choose from — but we have selected just a few of the best to help get you started on your journey.
Slushpool was the first Bitcoin mining pool released, being launched way back in 2010 under the name “Bitcoin Pooled Mining Server.” Since then, Slushpool has grown into one of the most popular pools around — currently accounting for just under 10 percent of the total Bitcoin hash rate.
Although Slushpool isn’t one of the very largest pools, it does offer a newbie-friendly interface alongside more advanced features for those that need them. The pool has moderately high fees of 2 percent but offers servers in several countries — including the U.S., Europe, China, and Japan — giving it a good balance of fees to features.
BTC.com is another potential candidate for your pool and currently stands as the largest public Bitcoin mining pool. It is responsible for mining around 17 percent of new blocks. Being the largest public mining pool provides users with a sense of security, ensuring blocks are mined regularly and a stable income is made.

BTC.com is owned by Bitmain, a company that manufacturers mining hardware, and charges a 1.5 percent fees — placing it squarely in the middle-tier in terms of fees. Unlike other platforms, BTC.com uses its own payment structure known as FPPS (Full Pay Per Share), which means miners also receive a share of the transaction fees included within mined blocks — making it slightly more profitable than standard payment per share (PPS) pools.
Another great option is Antpool, a mining pool that supports mining services for 10 different cryptocurrencies, including Bitcoin, Litecoin (LTC) and Ethereum (ETH). AntPool frequently trades places with BTC.com as the largest Bitcoin mining pool. However, as of this writing, it occupies the title of the third-largest public mining pool.
What sets Antpool apart from other pools is the ability to choose your own fee system — including PPS, PPS+, and PPLNS. If you choose PPLNS, using Antpool is free but you will not receive any transaction fees from any blocks mined. Antpool also offers regular payouts and has a low minimum payout of just 0.001 BTC, making it suitable for smaller miners.
Last on the list of the best Bitcoin mining pools in 2019 is the Bitcoin.com mining pool. Although this is one of the smaller pools available, the Bitcoin.com pool has some redeeming features that make it worth a look. It offers mining contracts, allowing you to test out Bitcoin mining before investing in mining equipment of your own. According to Bitcoin.com, they are the highest paying Pay Per Share (PPS) pool in the world, offering up to 98 percent block rewards as well as automatic switching between BTC and BCH mining to optimize profitability.

Electricity Costs
While your mining hardware is most important when it comes to how much BTC you can earn when mining, your electricity costs are usually the largest additional expense. With electricity costs often varying dramatically between countries, ensuring you are on the best cost-per-KWh plan available will help to keep costs down when mining.
Most commonly, large mining operations will be set up in countries where electricity costs are the lowest — such as Iceland, India, and Ukraine. Since China has one of the lowest energy costs in the world, it was previously the epicenter of Bitcoin mining. However, since the government began cracking down on cryptocurrencies, it has largely fallen out of favor with miners.
Technically, Venezuela is one of the cheapest countries in the world in terms of electricity, with the government heavily subsidizing these energy costs — while Bitcoin offers an escape from the hyperinflation suffered by the Venezuelan bolivar. Despite this, importing mining hardware into the country is a costly endeavor, making it impractical for many people.
Finding ways to lower your electricity costs is one of the best ways to improve your mining profitability. This can include investing in renewable energy sources such as solar, geothermal, or wind — which can yield increased profitability over the long term.

The total computing power now dedicated to securing the bitcoin blockchain has set yet another record.

According to data from mining services operator BTC.com, the average bitcoin mining hash rate over the last two weeks has reached 71.43 quintillion hashes per second (EH/s), up from 64.49EH/s on July 23. The threshold was breached as bitcoin adjusted its mining difficulty at block height 586,672 on Monday 2:52 UTC – that is a 6.94EH/s, or 10.78 percent jump since mid July.
Bitcoin mining difficulty is a measure of how hard it is to compete for mining rewards on bitcoin. Just how difficult the bitcoin software makes it to generate new blocks adjusts every 2,016 blocks – approximately every 14 days – to ensure the block production time remains about 10 minutes at the next cycle.
Assume this additional 6.9EH/s (or 6.9 million tera hashes per second, TH/s) computing power has all come from powerful ASIC miners, such as Bitmain’s AntMiner S17 or MicroBT’s WhatsMiner M20S, both of which boast a mining rate of around 55TH/s and recently hit the market.
That means more than 100,000 top-of-line ASIC miners could have been switched on within the past two weeks. Further, given these products have been sold for at least $2,000 each, this equates to some $200 million in revenue pocketed for major miner makers.
The continued interest in bitcoin mining comes at a time when the cryptocurrency’s price appears to be en route to challenging all-time highs, however distantly, and amid the arrival of the rainy season in China, which leads to cheaper hydropower electricity costs in the country’s southwest provinces – a region that is reported to account for 50 percent of the global mining activity,
Miners in China estimated earlier this year that bitcoin’s hash rate in the summer would break the level of 70EH/s. To be clear, at several single points of time, bitcoin’s hash rate had already crossed that level in June and even reached 80EH/s around Aug. 1.
However, today marks the first time that the two-week average computing power has been able to remain above the 70EH/s threshold. As such, bitcoin’s mining difficulty has also set a new record of nearly 10 trillion.

Market change

Amidst this uptick in mining interest, there have been notable changes in the mining market, where top manufacturers are racing to produce more powerful equipment.
For instance, in Bitmain’s 2018 initial public offering prospectus, the Beijing-based mining giant claimed it had a 70 percent market dominance. Now, it may be facing serious competition from rival players that some believe are capable of shipping more top-of-line products with better profitability.
Michael Zhong, a former mining analyst who now operates mining farms at a startup called Force Mine, told CoinDesk that based on his experience, the production capacity ranking among major Chinese miner makers for their flagship products have changed over the years.
Zhong explained that from 2017 to 2018, Bitmain had topped the list with its AntMiner S9 series miners, followed by Canaan’s Avalon 8 series machines. InnoSilicon, Ebang and former Bitmain design director’s MicroBT were all in the third position at the time.
But from January to June this year, the delivery capacity ranking has reshuffled, with now MicroBT’s WhatsMiner M20 series at the top, followed by Bitmain’s S17 series miners and then InnoSilicon, Canaan, and Ebang, Zhong added.
According to F2pool’s miner profit tracker, Bitmain’s flagship AntMiner S17 Pro ranks third in terms of mining profitability, following BitFury’s Tardis and MicroBT’s WhatsMiner M20S. The cost for WhatsMiner M20S is around $3,000, while that of AntMiner S17 Pro is around $4,000 each, based on the information advertised on the two firms’ websites.
Although orders for these flagship machines have queued up until November and December this year, MicroBT’s founder Zuoxing Yang told CoinDesk previously that the bottleneck of production capacity is the availability of chips from suppliers.
For example, MicroBT uses 10-nm chips for its M20 series, which are relatively more affordable with a higher level of availability compared to more advanced 7-nm chips used by Bitmain for its AntMiner S17 series equipment.
While Bitmain has always been relying on chips supplied by Taiwan Semiconductor Manufacturing Company (TSMC), MicroBT has switched from TSMC to Samsung earlier this year for its flagship products.
Both TSMC and Samsung have estimated in their most recent Q2 earnings calls that the demand for cryptocurrency mining chips will come back in the third and the fourth quarter this year.

HaoBTC and ASICMINER, two largest mining farms

HaoBTC and ASICMINER, two largest mining farms
https://preview.redd.it/4em2av1yw9h11.png?width=646&format=png&auto=webp&s=5408280a960b80a756fe6fac8d9a41006e7bfcef
Currently, mining is a process of mining various types of currency, not just bitcoins, on huge production sites.
Earlier, it was possible to obtain cryptocurrency on an ordinary PC, but over time the labor intensity of the process increased, more miners appeared, and due to the complexity of the process and the increase in the scale of production, the equipment was improved and its cost therefore increased.
Mining farms produce computational activities using computer power (in most cases using video cards), the result is new "money".
The majority of those who mined the currency at its very inception have already become millionaires, and even billionaires, because the exchange rate has already reached, and even exceeded the mark of 10,000 dollars. Currently, it's still profitable to organize similar mining farms on home PCs, while they are able to recoup themselves.
Most of the mining farms are located in China (the reason is relatively low energy costs), as well as in Iceland.
The first is a mining farm ASICMINER located in 8 miles from the central district of Hong Kong, in the Kwaichun area. This farm occupies a relatively small area, but produces a huge amount of capacity, thanks to the latest technology. The basis of the farm is the racks, ASIC chips are located on them and produce the capacities that are necessary in the production of crypto currency.
The second large-scale farm is HaoBTC, located in China. This farm is not as equipped as the first, however, it produces a huge number of capacities.
This company announced the launch of Hash-Ex, a new bitcoin-exchange, offering customers to buy and sell a hash rait- part of the mining network of crypto-currencies. The minimum purchase is 1 tera hash, and such an opportunity is available not only to Chinese citizens, but also to all foreign users.
Xun Yue, Vice President of HaoBTC, states that they sold 10 petashash capacities, and the company itself is the only owner of equipment for currency management, in this regard does not depend on any external factors.
"We probably have one of the best farms in the world. Many publications have written about us. We work in the provinces of Sichuan and Xinjiang, we have tens of thousands of Avalon A6, we also use the Antminer S7 and S9, "Xun Yue said.
Initially, it seems that HaoBTC is a set of typical contracts for cloud mining, but the organization itself focuses on the fact that it has cheap electricity and does not charge funds for the use and maintenance of equipment.
According to ForkLog, in winter, a new mining farm was launched in China, its capacity reaches 140,000 kilowatts. One of its founders is Bitmain Technologies. Mining farms are gaining popularity as the currency itself, China in this regard remains the leader due to its relatively inexpensive electricity, without which it would be impossible to produce any crypto currency in the world.

4 Bitcoin-Newbies: What I have learned about BTC in 4 months

Hi guys,
I was introduced to Bitcoins last September. I didn't know anything about that and I started studying more about that.
I also found this forum and learned A LOT from you guys, so, to thank you all and to give back, I thought about doing a small summary of what I have learned so maybe new guys can find this helpful.
I will post a lot of links from outside and to my own posts, so people with the same doubts that I had can look for the answers that I got there and maybe that may answer their question too.
I learned: In September 2012, the very first thing I learned was from this video (like many of us) :
http://youtu.be/Um63OQz3bjo and this website: http://www.weusecoins.com
My friend introduced me to my first wallet and my first pool: http://bitcoin.org/ and http://bitminter.com/
I still didn't know what I was doing.
This amazing post resolve 99% of your doubts: https://bitcointalk.org/index.php?topic=9430.0
At the end September I found out that mining as we know it (or as I just knew) was about to end thanks to the ASIC machines. I didn't know what mining was and less idea of what ASIC was. So I started reading about that and I find many companies like Butterfly Labs, Avalon and BTCFPGA (http://bitcoinmagazine.com/tag/asic/)
I learned how awesome this forum is, willing to help a new guy like me
I was still learning how to mine, so I asked in this forum about that (https://bitcointalk.org/index.php?topic=114723.msg1236829#msg1236829) and they told me about pools, mining and I ended upgrading my graphic card (you can compare the speed of mining here: https://en.bitcoin.it/wiki/Mining_hardware_comparison and you can calculate how many bitcoins here: http://tpbitcalc.appspot.com/)
I found out all the pools out there (https://bitcointalk.org/index.php?topic=104664.0)
In October I was looking for rigs to mine (https://bitcointalk.org/index.php?topic=114823.msg1238027#msg1238027) because I found this video: http://youtu.be/eLt8Se3vVNg
Then I didn't understand why pay fees when mining, but this forum was even greater than what I thought https://bitcointalk.org/index.php?topic=115260.msg1242456#msg1242456
So once I learned about mining, I download GUIminer and I started mining in 3 pools at the same time (https://bitcointalk.org/?topic=3878.0)
After 40 days I mined my first bitcoin YAY! now, I wanted to know what I can do with that and I found places to buy with bitcoins like www.bitmit.net
I wanted to control my mining from my cellphone and I found Bitcare very useful (https://play.google.com/store/apps/details?id=org.cryptcoins.btcare&hl=en), and also Bitcoin Wallet to have a new wallet in your phone (https://play.google.com/store/apps/details?id=de.schildbach.wallet&feature=search_result#?t=W251bGwsMSwyLDEsImRlLnNjaGlsZGJhY2gud2FsbGV0Il0).
I wanted to buy more bitcoins, didn't know where. Dwolla https://www.dwolla.com/ and Mt.Gox https://mtgox.com/ were there for me. I found out that Dwolla is a pain in the ass. I had to wait 3 weeks to verify me and 3-5 days every time to make a deposit. But besides that, it works...althought I found this today: http://codinginmysleep.com/dwolla-begins-suspensions/
People who likes bitcoins don't usually likes PayPal
I also found places where they give bitcoins away...for free! http://makebitcoinsfast.com/ and http://earnbitcoin.wikidot.com/
I was new and happy until I found what a block is and how it dropped from 50BTC to 25BTC https://en.bitcoin.it/wiki/Blocks and http://blockchain.info/
You can know when the new block will happen: http://bitcoinclock.com/
More companies started to use bitcoins like WordPress (http://www.forbes.com/sites/jonmatonis/2012/11/16/whats-your-bitcoin-strategy-wordpress-now-accepts-bitcoin-across-the-planet/). You can even buy a house with btc! http://bitcoinmagazine.com/where-to-spend-your-bitcoins/
Cool sites that I still don't understand like: http://cognitivemining.com/ or http://bitcoinstatus.rowit.co.uk/
The biggest wallet so far had more than 613,000 BTC and its own site (http://1dkybekt5s2gdtv7aqw6rqepavnsryhoym.com/)
You can watch how bitcoins are going higher or lower in sites like here: http://bitcoinwatch.com/ and http://bitcoin.clarkmoody.com/
That a guru of Gold and Silver, is accepting Bitcoins in his web: http://mogamboguru.blogspot.com/
They have more names than just bitcoins... Sub-units of a bitcoin such asmillibitcoins ("Millies") or microbitcoins ("Mikes"). The Bitcoin protocol uses a base unit of one hundred-millionth of a Bitcoin ("a Satoshi")
What 2013 has in store for bitcoins: http://bitcoinmagazine.com/the-next-year-in-bitcoin-what-2013-has-in-store/
Some companies are afraid of bitcoins like apple and why: www.forbes.com/sites/jonmatonis/2012/06/13/why-apple-is-afraid-of-bitcoin/
You can help others by crowd founding with btcs: https://bitcointalk.org/index.php?topic=118458.0
You can bet anything: http://betsofbitco.in/ or http://bitbet.us/
And also short cut your wallet: http://payb.tc/
Hitler sells alls bitcoins: http://youtu.be/alc0gG0u48M
That if the bitcoin drops to $4 (it was my dream )... 82% of the people would buy all the btc they could https://bitcointalk.org/index.php?topic=137249.0
Casinos will make money....ALWAYS, any currency, any country: www.forbes.com/sites/jonmatonis/2013/01/22/bitcoin-casinos-release-2012-earnings/
There is wikipedia about bitcoins (http://en.wikipedia.org/wiki/Bitcoin) and there is a wikipedia only of bitcoins: (https://en.bitcoin.it/wiki/Main_Page)
Blogs keep growing to understand better about bitcoins: http://www.thebitcointrader.com/
I learned the hard way that if you have several wallets in your Bitcoin Wallet in your phone, it can crash and lose money. Be careful. https://bitcointalk.org/index.php?topic=137785.msg1468748#msg1468748
You can have multiples wallets in your computer thanks to: https://multibit.org/
I thought a fork was for eating, but there are more https://bitcointalk.org/index.php?topic=136802.msg1457287#msg1457287
There is no flaws in bitcoins: https://bitcointalk.org/index.php?topic=136740.msg1456910#msg1456910
Also, if you sign your account of the forum with your wallet, your nickname would be attached to it, always: https://bitcointalk.org/index.php?topic=137667.msg1467500#msg1467500
You must create a SECURE wallet: https://bitcointalk.org/index.php?topic=17240.0
And that's it so far. I'm still learning but I can see how much I have learned in just 4 months. I got my wallets secured, with many bitcoins and waiting for an asic.
I hope this post can help anybody.
Thank you guys!
All the best.

Frequently Asked Question: What's an ASIC, FPGA?

So you're sick of just mining on your GPU, and not a fan of the electric bill after a month of mining? There has to be a better option out there than your loud GPU in your gaming computer. There is!
Shortly after GPUs became popular for bitcoin mining, enterprising folks started looking at other things they can re-purpose to mine bitcoins more efficiently. Around mid-year 2011, the first devices sprang up that are called FPGAs or Field Programmable Gate Arrays. These are nothing new to the hobbyist community, they've been around for a while for crackers and other security-conscious folks looking at ways to defeat cryptographic locks. Hey! I know something that uses cryptographic calculations to secure its network! BITCOINS! Yep, so some miners developed their own boards and slapped some FPGA chips on them (most commonly the Spartan-6), and wrote specific firmware and "bitstreams" to more efficiently calculate bitcoin hashes. The first generations were sort of slow, but still they had better efficiency than a GPU. Some of the latest generation included the Icarus boards, Cairnsmore, x6500, and ModMiner Quad.
In early 2012(i think my timeline is right), Butterfly Labs(BFL) was selling their own FPGA miner that hashed at 800 Mhash/s using 80 watts and only cost US$600 amazing! These grew very popular, but people could see that FPGAs still weren't the most efficient way to hash their shares. BFL then announced that they would be designing their own chips that would be orders of magnitude faster than anything ever seen. These would be the ASICs (or Application Specific Integrated Circuit)everyone is raving about. ASICs are--as the name implies--specifically designed for one thing, and one thing only. Bitcoins. This is all it can do, and can't really be repurposed like an FPGA to other applications. Who wouldn't want a US$150 "Jalapeno" that hashes at 3.5 GIGAhashes/s using only power from a USB port?? Crazy! So summer 2012, BFL says they will ship before Christmas. Various things happen and we now still don't have any confirmed ship dates from BFL.
A few other companies have sprouted up, ASICminer which I believe is developing their own chips to mine themselves, but in a responsible way as to not threaten the network with a sudden influx of hashing. bASIC was a fiasco that was developed by the creator of the ModMiner Quad(which is actually a fantastic miner, I own one, and love it.) where he took many preorders, promised lots of people amazing ASIC performance, but in early 2013 the stress of the whole endeavour got to him and he gave up, refunded money(I think it's still being refunded now, or maybe it's been cleared up already.)
Avalon is the only company we know has ASIC mining hardware in the wild. It is not certain exactly how many are out there, but they have been confirmed by independent sources. The Avalon units are expensive(75 BTC) and have been in limited production runs (or batches) of a few hundred units that were pre-sold out very quickly.
All of this info is gleaned from the Custom Hardware forum over at bitcointalk.org over the past year or so I've been involved in bitcoin. I may have some facts wrong, but this is the gist of the situation and hopefully gives you an insight on the state of the hardware war against bitcoin
Thanks for reading!

State of the Bitcoin community.

This may be a long post but I wanted to get a few things off my chest. Some of you may not like what I'm saying but if that's the case at least take the time to discuss it rather than downvoting me. I think that's what communities on Reddit lack - discussion is how we progress and sometimes it feels like all Reddit does is downvote instead of actually talking up.
Firstly - Bitcoin in the media.
It's no big news that Bitcoin was synonymous with Silk Road and the Deep Web for a while. You couldn't have one without the other. This lead to a lot of negative press for Bitcoin itself. I think it was handled quiet well, we showed the majority of people that Bitcoin was useable in a mainstream setting but I don't think we did enough. How often do we see the good features of Bitcoins like:
How often do we see these features? I recently saw a sign in my local shop saying they couldn't accept credit card payments due to high fees. Imagine if they knew about Bitcoin, as long as they have a computer or even access to one they could attract a wider audience.
I think we can do a lot more to give out a clearer message about Bitcoin. I think a lot of the fear comes from the fact that people don't understand it. If we spend more time educating then we can get a more positive image out there.
Secondly - Miners, their profitability and other issues.
Thirdly - exchanges and how they work.
Bitcoin for devs and merchants.
I think a lot of work needs to be done for Bitcoin devs. Unlike other documentation, I found Bitcoin very hard to follow when it comes to dev. I understand the basics of coding and a few languages - not a much but enough to say make a web page or a automated program in C#. Imagine if you had Bitcoin dev dedicated websites like w3schools does for languages (I know w3 schools is a very bad benchmark but whatever). If more people understood how dev works then more people would attempt to get into it.
I think a lot of work needs to be done within the BTC community itself before we even think of making it mainstream. Even if the last price reaches $1000 it's useless if people don't know as much as should do.

Giving a tech talk about Bitcoin to my company

So the internet company I just started working for has occasional hour long tech talks and a slot opened up this week. I offered to give a talk about Bitcoin. There's a lot of interest already, partly because I'm new and partly because btc is so hot right now.
Reddit, I would like your help with making this awesome. Below are my scribbly notes of the high points I'd like to hit. ANything I am missing? Since it is only an hour I cannot go into too much detail (and I am far from an expert in the protocol, but the best way to learn something is to teach it!)
I was going to call it:
