The government already holds a lot of Bitcoin already, from the Silk Road confiscation. Who knows, maybe they'll print more dollars and buy more. Better they do that than give it to some foreign country.

Maybe mining?

I think at-least 50% is waste, atleast. Magnified in the last 5 years where governments printed double the money, govt spending shot up but looking around the world most people’s quality of lives declined. It’s a symptom of our broken money.
