NFT is like Digital Art, it is rare and the price can increase very high in just a few months, this price increase is due to the unique NFT and steps, the more rare the item is, the faster the price will increase.
Usually the increased price is very high for a picture of a world figure. I hope that NFT will last a long time, because after all there are risks if one day NFT becomes worthless because there are too many NFT that appear.
I feel that NFT will hardly become a sustainable trend in the future or even if it can exist with crypto, the returns in the trend will start to diminish when this is just a form of refreshing crypto, refreshing this market, we can look at Defi, IEO and some other form, they are created in times when the market is lacking stimulus, the explosion of the NFT has only increased our chances of making money. Profits will be relatively good for the starters to create more community of players, gradually it will become more rigorous and no longer profitable
