> This argument has never made sense to me because it's simply 1 implementation of cryptocurrency and has not even performed its function as such. I'm sure there are better possible versions. In fact, I highly suspect that a better alternative has ALREADY BEEN IMPLEMENTED! Quality of an implementation doesn't imply success. Success also depends on other factors. History is full of examples (e.g. Betamax). Plus, it's very naive to assume that a Bitcoin is nothing because the only things that gives it value is the belief of people. Belief of people has value. Plus, it's not clear how long the prices will rise, and if something's going to happen in the meanwhile (e.g. more shops accepting it). If it's a bubble, it can't be said with certainty until the bubble bursted.
