This means that 79% of all NFT collections – otherwise known as almost 4 out of every 5 – have remained unsold
Anyone taking bets on how much of the remaining 21% were "sold" on paper only ie. wash traded? None of these statistics were ever reliable. Hundreds of thousands of NFT collections minted, almost all of them fishing for a single sucker to bite and make it worth the gas costs. It would probably be more useful to look only at collections officially associated with some already well-known brand/artist/celebrity.
TL;DR: A recent report reveals that the NFT market has collapsed, with 95% of NFTs being practically worthless. The hype around NFTs peaked in 2021, but since then, interest has waned, leaving many artists and investors in a tough spot. While not all NFTs are scams, the majority have lost their value, and the environmental impact of crypto remains a concern.
