True, but environmentalists will point out that transactions are taking place worldwide, on many computers, all generating heat that contributes to the climate heating up. As such it's not really about energy generation, because sustainable plants like solar can take care of that in the Sahara, but about what that energy does to the planet. A single computer in a room raises the temperature there, during winter I can feel the difference clearly between my study and the room next to it. Air-conditioning units keeping server farms cool releases a lot of heat to the outside. And as it becomes warmer for all of us, we buy more air-conditioning systems, spurring on an evil cycle.

A great thing about the new technology is that medical science now improves by the day, many medical procedures today didn't even exist a decade ago. So that's good news for you. You'll just need a lot of crypto for it, but it seems you're doing well in that department.
