to produce one btc requires 20 GWH.   this is more than 3x the demand of the state of massachusetts at 6 GWH, all this to produce $54K.   The costs of this 20 GWH is (assuming 20cents/kwh) is $4,000,000

Annual Energy Consumption Electric Power: 55.3 TWh (1% total U.S.)

120 gigawatts entire BTC network

72,000 GW for one BTC

72,000 GW / 3600s = 20 GWh

For Massachusetts

55,3000 GWh / (24 x 365 h) = 6.3 GWh or less than 1/3 of BTC mining

Assume 20 cents/KWh electric rate

20,000,000 KWh x $0.20 = $4,000,000 cost of electricity to mine one BTC

1 BTC is now at $55k

Whether one decides to buy bitcoin now or $4M is the real question.
