The Hard Math Behind Bitcoin's Global Warming Problem
Let me freak you out for a second. You know what bitcoin is, right? I mean, no, but quickly, it’s a “cryptocurrency” that’s basically secret computer money. One bitcoin, which doesn’t actually have a real, physical form, is worth at this moment upwards of $16,000. But to get one, you either have to buy them from online exchanges or use specialized computing hardware to “mine” it. That last bit is where the freak-out comes in.
