Bitcoin's network difficulty drops to ~131.43 T on May 2. That's another big difficulty drop for 2026. Network hashrate sits at 1,040 EH/s. 90-day difficulty trend: -4.29%. What that means is fewer machines competing for the same block reward. Each remaining miner earns slightly more Bitcoin per terahash. The miners coming offline are the inefficient ones, mostly air-cooled, 30+ J/TH, residential power at $0.14/kWh. The miners staying online run at $0.07/kWh under hydro cooling. That's the shape of mining in 2026. The inefficient operators leave and the hashrate consolidates with the operators who own their power.
