F2pool's online data shows that when the price of Bitcoin is around $84,803, more than half of the mainstream Bitcoin mining machines are on the verge of shutdown or already operating at a loss. Out of 135 mainstream mining machines, 68 models (about 50.4%) have negative daily net income, meaning these devices can no longer profit under current electricity prices ($0.06 per kWh). Among the remaining 67 profitable mining machines, the electricity cost for 16 models has exceeded 60%.
