One of the main reason why NFTs is getting plenty of interest even to those people who doesn't really know cryptocurrencies is because they tend to gain on it such as NFT games, artworks, showcasing their talents and etc.
Don't be too sure mate, not everyone will be willing to hold an NFT till its value increase, recently some people bought cryptopunks and were selling it at even 50% loss, NFTs is not an automatic value creator it takes time, the worst part is if the NFT is on ETH network it would require alot of money for gas fee, because of the high gas fees I haven't been able to participate in the NFT craze, thanks to paras and mintbase on Near Protocol I can buy as much NFTs as I want since the gas fees on Near Protocol is very low but transactions are super fast.
