Some coins like Bitcoin and Monero have utility outside of speculation, so probably not.
Disclaimer: I own some XMR, but not much.
Painful as it is, this is still just a correction. Reverting to more realistic valuations after a period of hyper growth and reckless speculation can hurt but it’s not the end.
That's the problem, though. What's a "more realistic valuation" for something that has no intrinsic value?
