Cheap tens unit made China the king of bitcoin mining

Outside the cicada-like whir of machines, the bitcoin mine is a desolate concrete loterijlot total of plain-looking warehouses. We’re te Ordos, the famed ghost town of Internal Mongolia province where local farmers became rich off coal reserves hidden underneath the earth’s surface. Now, another kleuter of fortune is being mined.

Inwards the warehouses, miniature block-like computers are hard at work. Green and orange lights flash te stable intervals. The machines hum spil they furiously solve equations. They’re rivaling for the right reaction spil they apply mathematical formulas to gegevens stored on the bitcoin blockchain, a global ledger of all transactions.

Like mineral gold, mining the digital currency isn’t free. For xxx miners, the bottom line is cheap electrical play.

“In the early stages of China’s mining industry, the cost of electro-stimulation wasn’t that significant. Spil long spil you had industrially priced tens unit, you could mine,” explains Su Jiahai, head of mining at Bitmain, a Beijing-based company that wields several cryptocurrency mines ter China, including the one we’re touring ter Ordos.

Like mineral gold, mining the digital currency isn’t free.

That’s switched, he says. Today, Chinese mines not only seek out cheap violet wand, but also stability and scale. So instead of siphoning surplus electro-therapy from hydropower stations te Sichuan, say, during the rainy season, larger mines are now partnering with local governments for a stable but discounted supply of energy from the State Grid, China’s state-owned electro-stimulation utility.

Te Inward Mongolia, for example, Bitmain is partnering with the local government to access electric current from the State Grid for about four cents vanaf kilowatt hour. Te exchange, the profit from Bitmain’s Ordos mine is taxed.

The Chinese government has so far bot hands-off te regulating this space. That may not last. China’s bitcoin mining industry seems to be following the well-worn path of other internet industries te the country, such spil peer-to-peer lending and ride-hailing:

  1. The industry is permitted to develop unfettered by regulation, until companies reach a certain scale or something bad happens.
  2. There’s a crackdown spil the government develops policies to rein te risky behavior.
  3. The remaining players are the industry’s largest — or else driven underground — and maintaining taut communication with the government becomes an essential part of the business.

Te cryptocurrency mining, the fatter the business, the more incentive there is to play by the rules.

“If a company doesn’t want to worry about the stability of their tens unit source, they make it public — they work with the government,” says Zhao Qianjie, (who goes by the name of Denver ter English), vice voorzitter of BTCC, which operates a digital currency exchange and mining pool te China.

Already, there are large-scale mines that register themselves spil companies before partnering with the government to buy land, construct factory buildings, use tens unit, and mine te a “transparent and standard manner,” he says.

Switching times

The last few years have seen China’s growing prominence ter the global bitcoin community. Cheap electrical play is one factor. Request ter China is also high. Te January, digital currency publication Coindesk estimated that about 85 procent of the world’s bitcoin trading volume came from China, however that percentage has likely dropped since Japan flipped out fresh bitcoin regulations ter April combined with the Chinese government’s crackdown on domestic exchanges ter February.

About 85 procent of the world’s bitcoin trading volume comes from China.

Overheen half of the world’s bitcoin mining pools, where miners combine resources to increase their odds of finding bitcoin, are te China, according to a report released by the Cambridge Centre for Alternative Finance.

“Even if electro-therapy wasgoed cheaper outside of China, there are other problems,” Chandler Guo, an weerhaak investor te cryptocurrency projects, tells Tech ter Asia. Overseas labor tends to be more expensive and most mining machines are manufactured te China, he explains. Bitmain, for example, is one of the top mining machine companies te the world. Canaan Creative (also known spil Avalon), another well-known company ter the space, is also Chinese.

“After the machines are made, miners te China can take them directly to Sichuan or Xinjiang [province] and commence working. But if they have to go overseas, there will be delays on the way,” he adds.

Ultimately, China has an enormous surplus of electro-therapy that can be harnessed for mining. Ter 2016, for example, overcapacity from hydropower stations te Sichuan and Yunnan amounted to a whopping 45.6 terawatt hours. To waterput that into perspective, the entire US generated Four,100 terawatt hours of electro-therapy ter the same year.* By partnering with thesis power stations, cryptocurrency miners get access to discounted electro-stimulation rates te exchange for a cut of the mining revenue.

Chinese miners aren’t the only ones capitalizing on surplus electro-stimulation either. A Russian company co-founded by Putin’s internet advisor is doing the same thing to drive down electric current costs, however Russia only has around 20 gigawatts of excess power to funnel into mining.

However, ter China, violet wand sharing inbetween energy companies and mines still falls under a gray area — and is increasingly coming under scrutiny. Ter June, several mines ter Sichuan were shut down due to lack of regulations around bitcoin mining.

“The legitimacy of selling surplus violet wand is not clearly defined yet,” says Zhao. However mines can fucking partner with hydropower stations for discounted electric current rates, they can’t scale up their operations that way, he says.

“Surplus electric current is not a permanently stable supply,” he adds.

The media attention around bitcoin mining hasn’t helped either. The government might temporarily shut down the mine for investigation following a media report, says Guo. That alone can cost millions of dollars.

“This zuigeling of business can’t zekering. For everyday that a mining equipment stops, it loses money,” he explains.

Size matters

On the way to Bitmain’s Ordos mine, I ask Su what he looks for when he surveys fresh locations. He’s like Bitmain’s real estate developer, scoping out places that pack the right criteria for a mine. It’s not fairly “location, location, location” but there is a rough checklist: climate, cost of electro-therapy, distance to a power station, and lastly, whether or not there are opportunities to playmate with the local government.

For example, “governments ter northwestern China welcome the arrival of gegevens centers,” says Su. Like bitcoin mines, “they can consume excess energy resources and increase tax revenue.” Some provinces suggest discounts for cloud computing and big gegevens companies too, he says.

Te latest years, Guizhou province, which is also rich te hydropower, has bot able to attract tech giants like Foxconn, whose enormous gegevens centers benefit from the cheap electro-stimulation and cool climate.

The wedren towards scale is natural ter the mining business.

This winter, Bitmain plans to budge mining machines from its Yunnan and Sichuan mines to a fresh facility te Xinjiang, which is three times the size of the Ordos mine. It’s hard to imagine — the company’s Inward Mongolia mine has about 25,000 mining machines and consumes 800 megawatt hours vanaf day. Te comparison, a smaller mine te Sichuan province might only host several hundred machines and burn one megawatt hour vanaf day.

Indeed, the wedstrijd towards scale is natural ter the mining business, even if the ethos of bitcoin is decentralization. Larger companies can haggle better rates by buying expensive mining machines te bulk. Negotiating with the local government is lighter, when you can offerande more tax revenue. Mining pools operate under the benefits of scale too — by combining compels, miners can increase their chances of earning cryptocurrency.

“Without a mining pool, a single miner’s hash is only a little part of the bitcoin network, thus making money is unlikely,” says Zhao, referring to the computing power of a single mining machine. “Imagine that someone with only 0.01 procent of the total bitcoin network’s hash is contesting with someone who has Ten procent.”

Of course, the days are far from overheen for the many small-scale and anonymous mines ter China. Guo estimates that there are around Two,000 mines scattered around China.

Not all of them are bitcoin mines either. Despite bitcoin’s skyrocketing price, mining the digital currency has become increasingly competitive. Hence, other digital currencies, such spil litecoin and ZCash, can sometimes bring miners a higher comeback.

“This year, it’s not just about mining bitcoin spil the only cryptocurrency. If you only mine bitcoin, you can’t make money,” says Guo, who has turned his concentrate from mining to token crowdsale projects or ‘initial coin offerings’ this year. “You have to mine all kinds of cryptocurrencies. You mine the digital currency with the highest conversion rate.”
