So, honestly - you have about a one in ten chance of learning some actual science by watching YouTube videos - and about an 80% chance of being mislead by idiots.
While I appreciate your study, I feel your math, like the math of these videos, may be flawed...
Also, bitcoin transactions require barely any electricity at all, it's bitcoin mining that wastes valuable resources that could be more productively used on nearly anything else.
Except bitcoin mining is inherently tied with transactions: https://www.bitcoinmining.com.... bitcoin mining is how the transaction system works, verifying each transaction. The system blows through cheap energy to make fake cash. The whole system results in a massive waste of energy for an inefficient currency.
The one day you'd sell your soul for something, souls are a glut.
