Leveraging manias for social good sounds appropriately disruptive .. Is there a way to short NFTs? I wish I could proactively sell people's regret to them.
As Matt Levine would say, the way to do that is to mint and sell your own NFT. That way you are on the opposite side of the trade as the bulls who you believe are wrong.
The proper way to bet on NFTs being passé soon is probably to invest in something that's not an NFT.
