Already, the reduced exchange rate for bitcoins into dollars seems to be provoking some move toward consolidation bitcoin the industry. If bitcoin is going to enter the mainstream, the limit must be raised, or transaction fees must be significantly increased. Nov mining, at Follow The Economist on Twitter.

Feb 2, at Jan 30, at Jan 29, at Security firm TrendMicro stated in a new report that Google's DoubleClick ad services were used to distribute cryptocurrency mining malware.
A small Japanese startup is paving the way in ideating how bitcoin's experimental Lightning network could take shape on two fronts. I would like to receive the following emails: Still, acceptability may prove to be key in the advancement of bitcoin, since the more users are able to find places to pay with bitcoin, the more demand they will have for the available supply. Of course, bitcoin mining is not the only cryptocurrency mining taking place these days.
Any blockchain currency with proof-of-work features may be mined, and miners in alternative cryptocurrencies seem to find the activity profitable. How much is all this equipment dedicated to bitcoin mining, and altcoin mining, worth? The combined mining power on the network continues to increase. If you happen to earn enough bitcoin from the 25 bitcoin created in each block, plus transaction fees, to surpass these fees, then renting the gigahashes was a good choice.
Of course, given the enormous amount of computing power in competition with you, you should probably view the investment as speculative rather than as a sure thing. Bitcoin mining is energy intensive, so huge mining operations tend to locate where it is easy to keep machines cool or where energy is very cheap. Cheap coal in Mongolia seems to be stimulating bitcoin mining in that country. Unfortunately, not every bitcoin mining company has found a way to remain profitable.
Difficulty could be adjusted downward if a great many miners began pulling machines off the net, but for the past couple of years the trend has been upwards. Since ASICs were first shipped the difficulty has increased by a factor of ten thousand. How does bitcoin mining stack up as far as transaction processing goes? The bitcoin protocol currently can only process seven transactions a second, because of the 1 megabyte limit on blocksize, which is tiny compared to, say, Visa, which handles up to 10, transactions per second.
However, of course, the fee for each transaction is significant, especially for merchants who bear the brunt of the credit card processing fees. A recent transfer of tens of millions of dollars worth of bitcoin was recorded on the blockchain for a fee of about two cents.
For instance, successful miners have to wait for a further 99 blocks of transactions to be processed before they get their rewards--so there is a constantly refreshed pool of participants with an interest in ensuring that everyone else keeps to the rules. The system of rewarding successful miners with bitcoin has proved an effective way to get the currency into circulation. Operators of conventional payment systems live on transaction fees, but that business model would not have worked for bitcoin in its early days, because of a lack of users.
However, as bitcoin becomes more popular, the idea is that miners will be able to start charging significant transaction fees, and that these will become their main source of income. It will need to: Despite the slump in bitcoin's value--last year it performed even worse than the Russian rouble and Ukrainian hryvnia--the combined mining power on the network is still increasing, and some miners are still investing in upgrading their machines, making this one of the fastest-moving parts of the IT industry.
In the crypto-currency's early days, most miners were small-scale, trying to mint money on their home computers. This was Mr Nakamoto's libertarian dream: But as bitcoin's value rose, it all became more businesslike. Individual miners started to combine their computing power and share the rewards. Most mining today is provided through such "pools". Startups from all over the world began building specialised hardware powered by custom-built chips, known as application-specific integrated circuits ASICs.
Leaving the amateurs behind, these firms soon became locked in a digital arms race. Microprocessors usually double their power every 18 months, a rhythm called Moore's law. In the case of mining ASICs, this doubling has occurred every six months. Mining has also moved into the cloud. Given the nature of the business, one would expect the bosses of bitcoin-mining firms to be super-geeks. But instead of coming from Silicon Valley, they typically hail from places like Sweden and Georgia--and talk and often look more like real miners.
Like other energy-intensive industries such as smelting aluminium, minting bitcoins is more efficiently done at scale, and in places where electricity is cheap and reliable. It also helps to be somewhere cold, to reduce the cost of cooling the machines. KnCMiner's hangar is near the Arctic Circle and right next to a hydroelectric dam. The makers of mining computers benefit from the way the bitcoin system adjusts the difficulty of the puzzles, every two weeks, according to how much computing power is hooked up to the system.
In theory the difficulty can be adjusted in both directions: But until now the difficulty has mostly gone upwards: As a result, new mining computers, which each cost several thousand dollars, have been becoming obsolete in a matter of months. When the bitcoin price was rising, many of its fans thought investing in mining equipment was a better bet than simply buying and holding the currency.
They were willing to plunk down top dollar months ahead of delivery of the computers. These advance payments allowed KnCMiner and other makers to manage without having to raise any financing. What happens in the wake of the bitcoin price collapse is unclear.
The long queues for mining rigs have dispersed. Demand for renting cloud-based hashing-power is stagnant. Many equipment-makers have ended up running the machines for their own benefit--and selling some of their stock of bitcoins to cover costs.
Some people say this is why the currency has kept falling. People in the industry are already discussing at what price mining becomes unprofitable. But Mr Cole is unfazed. Where others see a weak price, he just sees all the bitcoin yet to be mined, and lots of struggling rivals set to exit the business.
If other miners do give up, the difficulty of the puzzles may fall--so winning bitcoins would get easier. Perhaps it is a good thing that the breakneck growth of a year ago has ended:
