it's not FUD, it's a real problem. I think those who deny this are the same people who deny global warming. Bitcoin protocol has an infinite demand for more and more energy. People like to say that banks spend more energy, but what's the difference in scale? Any honest analysis must consider the scale.
certain stat sites estimate that US 'spends' $10.7trill a year
bitcoin does about $1.05b a day $383b a year
so the scale of value is ~28x
16,500,000,000,000kwh for the us to 'spend' its money
16.5pwh a year
16,500twh a year
1,884gwh per hour(1.88twh per hour)
110exahash /110 s19prothash= 1mill asics at 3.25kwh
3,000,000kwh per hour
3gwh per hour
US 1884gw btc 3gw
US $10.7trill btc $383bill (10.7t is 28x more then $383b)
____________________ (divide the 1884 and 10.7 by 28 to get equivelent to btc value moved cost)
US 67gw btc 3gw
US $383b btc $383
so yea a direct comparison for fiat $1 per kw and btc value $1 per kw
the btc is actually 12.3x BETTER than fiat
