NFT was always a meme and crypto has proven its staying power.
Crypto has shown people are willing to use it as a currency for investment and day to day transactions. Its held value for a significant amount of time. The tech is evolving still and people see a lot of value in having a currency that operates outside of Governments in a decentralized way even if some people will misuse that freedom.
Where is this happening?
Black market goods? Of course.
Avoiding taxation? Absolutely.
Day to day purchases? Not that I've seen.
But as a protocol it has legs and is still used under the hood in projects.
Cryptokitties was always the best monetisation use case for NFTs, and its still going.
