Honestly NFT's are definitely like tulip mania 2.0, that is not even a hard guess. It is obvious that people are not doing anything that makes sense during this period, they are spending money on things that actually has no worth at all. I hope that one day people will realize that they are doing something wrong, but the moment that is realized we are talking about something that is very horrible for all those people who spent that much money so far.
I believe it would help give NFTs “value” if they were issued in the Bitcoin blockchain. The NFTs themselves might be a victim of bull-bear/mania-depression cycles, but they will be encased in a multi-generational protocol in Bitcoin. Shitcoin blockchains will die, Bitcoin chugs along.
