The funny thing is that if there really is anything revolutionary to be done with crypto currency it will happen when they are cheap.

Ethereum's "world computer" vision for example, might actually lead to some neat stuff if it was dramatically cheaper to run smart contracts.

Cheap, less volatile BTC makes it much more useful as an actual underground currency.

I sort of want crypto to crash, not because of some schadenfreude, but because so much more technical experimentation with ideas can happen if it's dramatically cheaper to play with.
