Bitcoin is Now a Thing

I'm not sure if this is new or if I just didn't notice it last year, but the tax software now includes a question about whether I've traded cryptocurrency in the last year.

(I have not. But I have been somewhat worriedly staring at the news of Wall Street investment places getting into bitcoin; that is not going to help with the "this is a ridiculous speculative thing and the sooner the bubble bursts the better off we'll all be" aspect of it.)
