You are quite right about NFT being very promising and might be the next direction for the development of most cryptocurrencies. NFT idea is a good and unique one but over time, it seems to be lagging behind maybe because there are yet to be a team willing to bring in good strategies that will turn things around or people are yet to understand its concept. Also, I think the NFT started picking up this year with the advent of DeFi because I noticed that most team are now working on it, hence the reason why most people believes that NFT will most likely be the next trend in the crypto space since Defi trend is already slowing down. However, just like DeFi projects and the ones before it, once the hype gets over to NFT it is important to invest wisely.
