The total hashrate of the U.S.-listed bitcoin (BTC) miners tracked by JPMorgan (JPM) has almost doubled from a year ago and now accounts for about 29% of the global network, the bank said in a report on Tuesday.
The combined hashrate of the 14 companies "has increased ~95% y/y to 244 EH/s, versus a 45% increase in the network hashrate," analysts Reginald Smith and Charles Pearce wrote.
The network hashrate is a proxy for competition in the industry and mining difficulty. The Bitcoin network hashrate has risen about 6% so far this month, and has climbed 45% in the last 12 months, the report said.
