When 50 BTC was worth less than electricity costs: Bitcoin mining 16 years ago
A resurfaced post from a bitcoin forum dated Sept. 7, 2010, shows early miners questioned whether earning 50 bitcoin per block was worth the electricity used. A user calculated a home computer drew about 140 watts and would take about 14 days to mine a block, consuming about 47.3 kWh, or $5.68 at 12 cents per kWh. The thread also discussed GPU mining, performance gains and rising network difficulty.
