The technology is here to stay. If BTC takes a deep, it would go back up just because it's not centralised within any country's eco-system. If the US shuts it down the rest of the world moves on with it. If China shuts it down, South Korea and all SouthEast Asian countries adopts it fully. Crypto hasn't been adopted mainstream wise, check the core market capitalization of Cryptos; it's 80% Asia funded. Think what happens when Europe, Americas and Africa puts their individual weights on it then watch the true rate of Cryptos mostly those with the ability to store value and then utility tokens.
We haven't scratched the surface yet.

Naturally people are sceptical about change or new processes which contradicts their paradigm, with time you'd see things metamorphose and metastasize in a positive way.
