It's entirely possible it will crash, but I also don't think it'll go bankrupt or anything.
I don't typically buy stock to flip it right away; I have some Nvidia stock that I bought the day after ChatGPT was launched, and I bought a bit more when it was $90/share about a ~year ago. If it drops to $100, then I'll still be in the black, but even if it drops to $50, I'm not going to worry because I figure that I can just hold onto it until another upswing.
Nvidia has been around long enough and has enough market penetration in datacenters and gaming that I don't think it's going to go bust, and I figure that it will eventually appreciate again just due to inflation.
If it appreciates just due to inflation you didn't actually make any money. Unless your investment beats inflation, you lose value.
