[Bitcoin's 7-Day Average Hashrate Drops to Three-Week Low, Miners Shift to AI Computing Power] According to Crypto.news, Bitcoin's 7-day average hashrate fell to 915.8 EH/s on September 26, marking a three-week low, with a weekly decrease of approximately 34.86 million TH/s. Miner reserves also dropped by 1,530 BTC during the same period. The main reason for the decline is that some mining companies have redirected computing power to AI contracts. For instance, Hyperscale Data has shut down its Michigan mining facility to prepare for AI operations, and Ethiopia has reduced power supply to miners due to declining reservoir water levels.
