I'm not impressed by his conviction. He has a yacht and a mansion and a huge stake in a giant successful business. Bitcoin goes to zero and he is inconvenienced a bit, but still richer than I'll likely ever be. He is not actually "sitting on one chair" as he put it.
True conviction is someone who is sacrificing comfort saving with no other assets because they earn so little they can't even afford to diversify.
I'm between the two, like I assume most on nostr are. I'm not trying to talk myself up. I just get tired of hearing about the risks the ultra wealthy took when they really didn't risk much at all.
