Hello everyone, I'm sorry if this sounds stupid. I am a learner in the crypto scene.

I know BTC probably isn't going to crash anytime soon, and in this case, if a huge BTC crash happens, eventually most altcoins would suffer alot.
But, in this cenario of crash, would most of the alts be done? I mean, what are the odds of altcoins surviving this crash? Would they then get negotiated with fiat?
I was just wondering this and wanted to discuss this (distant?) possibility...
