The difficulty of mining a bitcoin block fell by 7.32% today, with miners powering off machines as a brutal bear market eats into profit. The adjustment at block height 766,080 is the biggest downward change since July 2021, data from the mining pool BTC.com shows. That was when hordes of miners dropped off the network following China’s ban on the industry. The country was the world’s biggest bitcoin mining hub at the time. (Coindesk)
