Tulips had value in 1635 then two years later the market collapsed.
I don't know what's going to happen in the future. Eventually the flow of people new to cryptocurrencies will stop. I figure one of three things will happen:
1. Values hold and people treat cryptocurrencies like gold.
2. The market collapses.
3. Somebody finds something useful to do with cryptocurrencies and values appreciate with less volatility.
