But there ARE other hard currencies and millenia of use and debasement of those to study. BTC is the hardest currency yet, but... It's still used to do the same things. It's NOT that different than gold/silver/cows/beads. The way it can be used is easier/faster/more secure, but, it's still just a store of value that is all the good things that hard money is. So, yeah, we're just getting started, but... It's not like there's no precedent.
