Right, and public ledgers, digital money, smart contracts will be used by the people in the future, but BTC and ETH prices are as important as WebVan/Pets.com stock prices for that to happen.
Smart contracts are just software, so I agree. Software will be used in the future.
I still don't know the value of public, distributed, cryptographic ledgers. They don't seem to solve real-world problems because there is no way to tie them to the real world. They preserve lies just as well as they preserve truths.
Digital money is useful, but fiar is already digital.
BTC is used for bypassing government controls (drugs, money laundering, currency export controls, remittance) There will most likely be demand for that in the future. I'm not saying anyone should invest in crypto, I'm just saying those use cases exist.
