Παγίδα στη «φρενίτιδα» του bitcoin απειλεί χιλιάδες χρήστες

epaselect epa06062675 (04/26) Bitcoin miner Huang inspects a malfunctioning mining machine during his night shift at the Bitcoin mine in Sichuan Province, China, 26 September 2016. Miners can check a machine's condition and operations using phones and personal computers. For most issues, they can simply restart a machine. 'If it's a complicated problem, we just ship it to the factory and let them fix it,' Huang said.
China is one the main exchange market of bitcoins although the digital currency exists in a legal limbo and prone to speculation. The country hosts some of the biggest 'mining pools' in the world, clusters of supercomputers which task is minting new bitcoins and maintaining the system, sometimes installed in shady places close to power plants. Sichuan has become known as 'the capital of bitcoin mining' as entrepreneurial Chinese set up 'mines' there due to its abundance of hydropower, perfect for the high electricity needs of the large number of computers required for Bitcoin mining. Bitcoin mines are buildings with warehouse-like structures equipped with massive numbers of microprocessors with which 'miners' solve complex math problems and are rewarded in the digital currency.
The industry exists in a legal gray zone in China, and the miners in this story, concerned about attention from the government, asked not to have their full names or the names of the villages where their mines are located mentioned in this story.
