People's Bank of China (PBOC) recently held a camera meeting on the use of electricity for bitcoin extraction. The validity of the information has been confirmed by Tenant Finance.
** Updated January 3, 2018, 10:00 AM EDT: Recently from Caixin publication, there is a conflicting report with this story, in which details of the so-called 'closed meeting' organized by PBOC did not come out. They do not even ask for closure of mining areas before the deadline. The government does not restrict or support the removal of bitcoin. In simple terms, officials will have stopped offering preferential policies for energy use, land use and taxes. ** SOURCE https://news.bitcoin.com/chinese-central-bank-hosts-a-closed-door-meeting-over-electricity-usage-of-bitcoin-miners/
