the actual hashrate for the year is 155exa(155477763.7thash) average
Yesterday it was 202 exa so 30% more then you stated.
so its actually 40TWH not 200
thus not even a 3x in the last 5 years
Even if thats true it does only prolong the problem and doesnt solve it
but as you can see ASIC efficiency has changed in 5 years to be 3x more efficient
Thats exactly what I told about new maschines lowering the network safety when the whole network keeps the same energy consumtion
