Over the past 24 hours, the difficulty of mining BTC has decreased by 11.2%, which is a record value since the ban on mining digital assets in China, introduced almost five years ago. China topped the ranking of states by the hashrate of the BTC blockchain, so disabling equipment on government orders caused a repeated decrease in mining complexity by 12.6-27.9% from May to July 2021.

As the editors of Happy Coin News found out, the difficulty of mining BTC began to fall a month after the emergence of a downward trend in the coin market in early October 2025. In three months, this indicator has decreased by 19.3%, and given the relationship with the bearish trend, it can be assumed that the complexity of mining will continue to decrease if bitcoin becomes cheaper.

Changing the difficulty of mining BTC

In addition to the downward movement in the bitcoin market, the difficulty of mining was affected by adverse weather conditions in the United States. In January, there were severe snow storms in 34 states that destroyed power lines. As a result, some companies mining digital assets had to suspend their work.

In this regard, the computing power of the world's largest mining pool, Foundry USA, has dropped by 60%. By February 8, the hashrate of the platform had increased, but its current value of 354 Eh/s is 11.5% lower than the value recorded before the power supply failures.
