I think it's mostly the FTX tragedy, not something like people have learned about NYKNYC. However, a little percentage of people have learned what is a custodial wallet and we should avoid them. In one of my Facebook groups regarding bitcoin, people started to look for non-custodial wallets but before the FTX issue, they never bother to learn even despite my continuing awareness article on such issues. However, this is not the first time. There was mtgox exchange that had almost the same issue. Who has learned? Not more people than who have been the victim.
