In my perspective, I don't see this in NFTs as future the it's been heavily hyped, and I wouldn't advise an average man like me to buy an NFT instead of investing in altcoins and Bitcoins. They were worth a dime yesterday, but the credible ones have maintained their road map and whitepaper development today.
It's not all of NFT can be considered as investment bitcoin and altcoins. The thing that already forgotten by people when they were investing in NFT and it will not be so liquid as when they were buying altcoins or bitcoin that have so many markets and liquidity. There are various NFT right now. Investing in the coins will always become the main thing. NFT was just a part of feature that already offered by the developers. I would like call this as a feature. The main thing will always be the token or coin issued by the developers.
Buying an NFT today is dangerous, and everyone is hopping on it since there is amazing money to be made in there, conduct your own research thoroughly.
NFT was not liquid, some may not but if it's related to the art which was not popular among the crypto users and it will be a high risk bet for sure. It's quite different when you're buying NFT that has so many utility like in game item or something else. It can be liquid as there's demand to sell it for money. You must know that if's not all of NFTs are bad.
