My personal opinion. NFTs will not survive the crash (whenever that occurs). I doubt crypto will either - but that's a tad more controversial. NFTs are plain silly.
And celebrities, who only bought them to be trendy, won't care. It will only be a tiny % of their wealth, and they can always write them down as a tax loss.
I am not sure the sales are real. If you wanted to rip Joe Public off for $200, then you show him all these people that turned $200 into $2,000,000 That's my take on all this - smoke and mirrors
