Bitcoin mining depends on finding a hash that starts with a whole bunch of zeros, which is more or less equivalent to being just close enough to a jesus that you can sell it for money.
Joining a mining pool gets you a relatively fixed payout, counteracting the lottery nature. You'd only have to burn one box of matches to get a guaranteed payout of 300/730000 of a jesus match.
Yes it's still a waste of power.
The cycles are not wasted - they secure a digital currency.
Banks and governments use immense resources to secure fiat currency.
If I use a car that gets 1 mile per gallon to visit my grandma, I'm wasting basically all the gas I buy, despite it getting me to my destination.
Proof of work is waste.
But why though? Is the USD that insecure? Is fraud so prevalent that its debasing the value of currency? Do we literally need to spend 70TWh per year, and that's just in its current state as a semi novelty currency/commodity, to secure the concept of money? Can you imagine how much it would cost to run bitcoin if it was the primary reserve currency of the world?
