The most important thing about NFT is use case. If there is no real use case then there is no point buying that.
Pictures of paintings sold as NFT have no real value and you will probably lose your money.
That's right, NFT is a very high risk investment instrument. The fundamentals of NFT are almost non-existent, only speculation. The use case is the value, if there is no other use for the NFT other than as a digital object, the hype that is happening right now can just disappear. It's the same with tokens, without a use case, these tokens slowly have no value, because they have no fundamentals that can drive buyer interest except for speculation.
