The problem with these NFTs is that you cannot sell them if no one buys them.
Most of NFT that can be considered as art like that isn't meant to be an investment, it was meant to be collectible just like how you buy arts or painting from an artists, when you buy it you want to put it on your wall and not reselling it in shop.
If you are looking for an NFT that can be resold easily then it's NFT that is based on game like for example an axie, or any NFT games items, these kind of NFT always have quite high demand because it can make the gaming experience better or to earn in game tokens.
Collectibles can also be used as an investment. if it has historical value, rare, ancient, then the longer the price can increase. NFT must fully have the support of its community in order to have value, and who has a taste in that field of art. which I wonder sometimes costs up to thousands of dollars, even just for a simple picture, but for art connoisseurs there may be a special value that makes it so highly negotiable.
while for nft gaming, it's easier for me to understand. where we can get or collect certain items from the game. For game lovers, this is a good opportunity to channel hobbies as well as investment opportunities.
