Bitcoin completed a new round of mining difficulty adjustment earlier today, with mining difficulty increasing by 5% to 150.84 T, reaching a new all-time high. This is the seventh consecutive increase in mining difficulty since July this year. This difficulty adjustment reflects the continuous growth of Bitcoin's network computing power, which has now exceeded 1.05 ZH/s. However, the surge in computing power has also put continuous pressure on miners' profitability. According to Luxor data, the "Hashprice" index, which measures miners' unit computing power income, has dropped below $50/PH/s.
