a big issue i always see in these debates are:
1. the bitcoin hashing electric estimates in the examples like the one i quoted.. are extremely high compared to reality, its like they think majority of network are still using bad inefficient hardware made in 2016 but used in 2021-23.. (facepalm)
2. nothing is mentioned about how much electric would have been used if there was no asic evolution. EG how much electric would be needed if the network was still ~320exa but done via CPU..
not many people mention how asics have saved alot of electric
3. altcoins like ethereum only have a crowd of 400,000 thus their CPU validation costs give a ethereum minting value at $35/coin
imagine if ethereum have 100million users.. (250x electric cost)
yep the cpu usage power of validators would exceed the 2mill bitcoin asic usage..
if ethereum ever got as popular as bitcoin. but stuck at CPU
IN-EFFICIENCY ethereum would waste more electric per eth of their 'validator' stake system
