Just hype. NFT is not a place for long-term investment, because NFT is not yet strong and consistency in the market is questionable. NFT needs further development in order to survive in the market, if you just take advantage of the hype to look for daily profits it's fine, but for long term investment, NFT is not a good place and the risk is very big.
I also agree with what you are saying because NFT does require further development so that it can be suitable for long-term investment because without it I think NFT is clearly not suitable for long-term investment other than looking for short-term profits.
