Digital currencies are something would have been great to invest in, in retrospect; but if you're in them now, continuously take profits, to make sure you come out ahead when normality kicks in. There's no Bitcoin-only economy that requires you to use Bitcoin to operate in it, like currencies. There's too many competitor crypto-currencies, and the bar for competition is sufficiently low that it's unlikely that Bitcoin will be the long-term winner. That makes it a losing bet; maybe not this decade, but sooner or later. Also, the slowness of Bitcoin transactions means that when the crash happens, and people start rushing out, they won't be able to get out very quickly. Hopefully people will see it as easy come, easy go.
