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.
The potential profit from hype is only for trading not for long term investment, investing in NFT is very risky because hype changes tend to change depending on the community's will, if the community is happy with the latest hype then the old hype will be left at the lowest price, so take advantage of opportunities to profit from hype not problem, but investing in long-term NFTs should be considered.
