Bitcoin's mining difficulty adjustment hit a new all-time high of 108 trillion (108T) in the latest epoch, reflecting the unprecedented amount of computational power directed at securing the network. The global hashrate has reached 920 EH/s, up 45% year-over-year.

Economics for Miners

For miners running older S19 generation hardware, the difficulty spike has pushed break-even electricity costs below $0.03/kWh in many jurisdictions. However, operators with the latest Bitmain S21 Pro (335 TH/s, 16.5 J/TH) and MicroBT M66S hardware remain profitable at electricity costs up to $0.08/kWh.
