33% sounds way too high for me. When I think about all the people I know, less than 5 are in crypto (as far as I know). I would estimate that a low single digit percentage of the general population (closer to 1% than to 10%) is engaging with / informed about crypto. Yeah, the rich have better access to information/ advisors working for them, but I would still be surprised if more than 10% are in crypto.
This picture here would also look different at 33%.
