The severe winter weather sweeping across the US has handed an unexpected windfall to well-prepared Bitcoin miners. Instead of using energy for mining, they’re selling that surplus power back to stressed power grids, making far more money than they would mining Bitcoin. “The grid may ask for that energy and the mining may turn off, but that means the grid is paying more for the energy than the miner is making by mining Bitcoin,” Scott Norris, chief mining officer at tokenised Bitcoin hashpower company Om ...

According to Miner Weekly, Bitcoin miners are now in their most difficult profitability environment ever, as November’s sharp BTC pullback pushed hashrate revenue down from roughly $55/PH/s in Q3 to about $35/PH/s, below the $44/PH/s median all-in cost for major public miners.
