The Problem With Bitcoin

Bob Greene: It's actually hard to pin down exactly what do you mean by saying money is a generally accepted medium of exchange. Some people who are endorsing Elon's statement said stuff like, wait, what's the problem, Bob? He says he doesn't think Bitcoin is yet money because I don't think it's generally accepted in the way the euro is or the dollar or the yen. "I'm saying putting aside all of the grammatical quibbles and stuff and philosophical deep thoughts," writes Greene.
