I don't think a scandal will drive Bitcoin from $240 billion to 0. There's enough interest that Bitcoin will retain at least some value even when it's clear that it will never be picked up for general use.
A lot has changed in 10 years. Crypto has gotten worse. Multiple exchanges were hacked, or turned out to be entirely fraudulent. Black markets came and went. ICOs for non-existent and useless products. The discovery that major participants in the system were manipulating coin values and were engaged in multiple types of financial fraud. The uptake of cryptocurrency as the primary means of paying ransoms to hackers who have encrypted your website, database, or computer. Facebook attempting to introduce its own cryptocurrency. The Bitcoin Craze where awareness of bitcoin hit the general public and the techies who got in first exploited the rubes for everything they were worth(and cryptocurrency industry's response to the criticism: they should have known better!?!? That tarnished all cryptocurrency in the eyes of the public and they learned to avoid all of it, not just Bitcoin. That on its own was a fatal blow to the uptake of cryptocurrency in general use, anywhere, and it was only a few months later that Bitcoin started getting removed from e-commerce sites).
All in all, I'm glad I got out when I did.
