The bubble pop will come when banks say they refuse to use any public cryptocurrency. If that happens (if, not when) then the hype will disappear rapidly and the market will continue growing organically. If it doesn't, then cryptocurrencies will differ from beanie babies (or tulips) in the sense that they are highly liquid and can lubricate real financial teansactions, and thus have value within the global financial system. The other aspect I think the people calling bubbles are underestimating is the liquidity of information and assets through this network. Speculators will invest primarily in the forefront of cryptocurrencies technology - ICOs, low and middle-tier exchanges - looking for the next 100x. As coins grow the capital from established coins will spread and risk, hopefully, will also spread. Information on every coin is readily available and people are trading and chatting about these things all day every dat, so rumors and news should diffuse and keep prices in line. The technology will improve over time, hopefully to a point where the valuation is justified. I'm not saying that will happen, but in my mind there is a plausible path, and that's enough for me to keep some money in.
