The kingdom of Bhutan has been quietly mining Bitcoin for years
I think it's kind of wild that you can just take a latent or otherwise inaccessible source of power and now convert it into money.And it doesn't really matter what the price of BTC is for something like this, as the resource is more or less entirely unused.  It's just sitting there, doing nothing, so any value you can make out of it is better than the nothing they're already getting.
