China plans to limit power use by some bitcoin miners, people familiar with the matter said last week, a potential challenge to an industry whose energy-intensive computer networks enable transactions in the cryptocurrency. The People’s Bank of China outlined the plan Jan. 3 at a closed-door meeting, according to the people, who asked not to be identified because it wasn’t public. They didn’t detail how authorities plan to enact the curbs.
South Korea began inspections at six banks including Industrial Bank of Korea, that provide virtual accounts to companies related to cryptocurrency trading, to clamp down on potential money laundering. The nation last month said it will restrictively allow cryptocurrency trading on only qualified exchanges and review a possible capital gains tax on crypto trading as a way to restrain the nation’s frenzied speculation.
