You clearly not understand the tech.  Even if every nation bans crypto, forbid the use and so on, there will be real world use cases, and because of the p2p nature, you can't forbid with any law my ability to send money whoever i want to. (And there's many intelligent people working on blockchain solutions to whiten the political and financial world, so the real rulers can fuck themselfs on the long term, technology will free mankind from the salary-slavery)
I don't give a shit to crypto/usd prices because USD is the biggest financial scam in the history. I'm waiting for a fiat money crash and then i will laugh.
