You have already answered your question. It's a hype and like all hypes, they have a duration. Just like when the ICO and subsequently, the DeFi hypes came and went. I think the NFT hype is ebbing. Sales dropped
Its a normal cycle and we should always learn from this though I still believe that some NFTs are meant to stay and they’ll continue to give good services but its not like before where the hype is still high, we might see a slower growth once the hype was gone already. I still believe on NFT games, they are good to play and hold.
