The art collections is not something you trade and flip for few profit, just like it is offline, art are supposed to be unique with value, kept and valued for it's uniqueness. I think this same idea should apply to NFT! Undoubtedly, huge value have been exchange trade NFT but in the future, NFT will be more than jpeg, it will become all sort of value in the metaverse, like a token of business, citizenship etc!
The problem with the art is the availability cannot be secure because it's just a mere file that can be copied and sold on the other NFT site. Looks like it won't double its price either after this crazy hype and everyone knows when there will be something new will come out, every expensive NFT will have their price crash and the late buyers won't recover his capital again. so it's better to be an artist who keeps selling his artwork than to become a buyer thinking when he holds longer, he profits higher.
we are indeed better at creating works of art than buying them at high prices, because every art will certainly appear newer works of art, so the trend will change, when buying at high prices and the trend is still bullish, don't be greedy to get profit, because like you said earlier, it will be difficult to recover. for the most obvious if we want to invest, I think bitcoin will certainly be an option
