Crypto Uses Lots of Energy:
As of this writing, a single transaction on the Bitcoin blockchain eats up the same amount of energy as the average US household in a 77.8-day, or roughly two and a half month, period. Ethereum, though nowhere near as large, still eats up the same amount of energy that a US household does in eight days.
I knew crypto was bad for the environment and used a lot of energy, but look at the scale of consumption. It’s insane. Especially when you add the fact that so much of this is mined in locations where coal is the energy source of the electricity.
Centralised currency is fine - unless you’re a grifter or a criminal.
