After the sharp drop in Bitcoin prices, almost all Bitcoin mining machines except for the latest Antminer are in a loss making state According to Antpool data, the recent drop in Bitcoin prices to around $78500 has resulted in the vast majority of Bitcoin mining machines being in a loss making state. Only the latest Antminer S23 series mining machines (such as Antminer S23 Hydro) remain profitable, with a daily revenue of approximately $18.53 per unit. However, older models such as the Antminer S21 series have a daily profit of only $0.12, while the Whatsminer M63S even incurs a daily loss of $0.47. Despite the decline in computing power caused by the North American cold wave, the global Bitcoin network's computing power remains close to historical highs, with an average monthly computing power of 927.7 EH/s in January. Miners' profits continue to decline, and some mining companies have turned to high-performance computing (HPC) and artificial intelligence services to diversify risks. In addition, the stock prices of major listed mining companies were also affected, with MARA Holdings falling 2.5%, Cleanspark falling 6%, and HIVE Digital falling 10%. Previously, it was reported that when Bitcoin falls to $75000, the 23.3W/T mining machine will reach its shutdown price.
