Bitcoin is Worth Less Than the Cost To Mine It (bloomberg.com)

The production-weighted cash cost to create one Bitcoin averaged around $4,060 globally in the fourth quarter, according to analysts with JPMorgan Chase & Co. With Bitcoin itself currently trading below $3,600, that doesn't look like such a good deal. However, there's a big spread around the average, meaning that there are clear winners and losers. From a report: Low-cost Chinese miners are able to pay much less -- the estimate is around $2,400 per Bitcoin -- by leveraging direct power purchasing agreements with electricity generators such as aluminum smelters looking to sell excess power generation, JPMorgan analysts led by Natasha Kaneva said in a wide-ranging Jan. 24 report about cryptocurrencies spearheaded by Joyce Chang. Electricity tends to be the biggest cost for miners, needed to run the high-powered computer rigs used to process data blocks to earn Bitcoin.

"The drop in Bitcoin prices from around $6,500 throughout much of October to below $4,000 now has increasingly pushed margins further and further negative for just about every region except low-cost Chinese miners," the analysts said, offering the caveat that their cost estimates may be skewed to the high side due to spotty data and conservative efficiency assumptions. The cost figures exclude equipment.

          The first is ridiculous, the second is correct. Correct to the point that you have to wonder if it wasn't designed that way intentionally. Already it has been shown to be vulnerable to the most obvious and blatant "pump and dump" schemes imaginable. Either the people who came up with it knew that and built it that way so they could rip a bunch of people off, or, they were so incredibly naive that it never occurred to them.

      I couldn't find reliable data in the time that I had to compare like with like, but a reasonable null hypothesis is that both claims are true. I can easily see how a large city could easily consume the same power as a modest-sized country.

      The mining cost is a function of the difficulty, which automatically adjusts itself to maintain the long term mining rate at one block per 10 minutes. As unprofitable miners drop out, the difficulty will decrease, and thus the cost of mining. Right now, you get 12.5 coins per block mined (plus all transaction fees on the transactions contained in that block). Eventually that 12.5 will be cut in half, and longer term, it will be zero. But by that time, so the thinking goes, bitcoin value will be stable enough to insure that miners continue to operate the network for the sake of collecting transaction fees.

      From the perspective of the system, mining isn't cheating (the only person who loses is the one paying for the resources). But if that was what the OP meant, then I concede the point. From a practical perspective, there is not much point in using PC's to do bitcoin mining at this stage. Without highly optimized hardware, you just don't get anywhere. You have to use dedicated miners.

      Let's not forget the original post.

      "A cryptocurrency powered by useful work won't actually work due to game theory; someone *will* find a way to cheat."

      My interpretation of this is that the OP thinks people will find a way to trick the system into awarding coin without doing the work required by the bitcoin system. That has never happened. Exchanges have defrauded customers. And in some cases, coins have been transferred because private keys were exposed somehow. People have run miners using power paid for by someone else. If that stuff is what the OP was talking about then, I guess the point stands. People will find a way to steal anything of value. But that is not a very insightful point to make.

      But nobody has figured out how to mine coins without computing the hashes required. Not a single transfer has been made (nor could it be made without destroying the system) that is not properly signed by someone in possession of the appropriate private key. The entire blockchain is public. Anyone can verify these facts for themself.

Buyer and seller will both trust visa, and visa will settle accounts from time to time on the bitcoin network as they see fit. However, except for the height of the mania, bitcoin transfer fees have not been anywhere near 40 dollars.Currently it is something like US$ 0.09 per transaction (which is much less than visa charges, but still, who wants to wait 10 minutes).

      It is unclear whether bitcoin will fail or continue to exist. But if an oil-producing nation unfriendly to the US decided to sell oil for bitcoin, that might be all it would need to be taken seriously as something with consistent purchasing power. Iran could achieve this single-handedly by promising to sell oil for bitcoin at price X for at least 3 months. That would peg bitcoin to the cost of crude. I think there is at least a 10% chance that bitcoin will replace the dollar as the world reserve currency some time in the next 10 years.

  3. Re:Feedback mechanism? by mamba-mamba · · Score: 3, Informative

    Not exactly. The feedback operates to adjust the difficulty of mining. The way it works is that if blocks are mined faster than once every 10 minutes (on average), the difficulty is increased slightly. If it takes longer than 10 minutes, the difficulty is reduced slightly. As machines go offline due to poor profitability, the difficulty will likely have to decrease to keep the mining rate constant. This has pretty much worked as designed over the inception of bitcoin. Despite all the hash power people have thrown at bitcoin, the rate of new block creation has stayed consistent on average. The difficulty is not updated super often. Here is a chart of difficulty vs time.

    https://bitinfocharts.com/comp...

    How much bitcoin you get for mining a block (the reward) is pre-determined by the implementation. It goes down by half every so often. Currently, the reward is 12.5 bitcoin. The "reward" represents the creation of new bitcoin. Once all bitcoins are mined, the reward will be zero. In addition to the reward, miners also collect fees from all the transactions contained in the mined block. Eventually, the only incentive to mine bitcoin will be to collect the transaction fees.

    If you haven't already read the whitepaper, I recommend it. It is not that long, and not that difficult to understand for people familiar with hashes and cryptography and whatnot. It is 9 pages.

    In my opinion, most coverage of bitcoin, even in the technical press, is woefully uninformed. The ONLY reason bitcoin takes so much energy to maintain is because the price rose so high, and the difficulty therefore increased. Now, as some of the mania is dying off, things should be a lot more sane, and non-profitable miners will bow out.
