In the end, it's all a gamble, I just like the odds better on some of them that few people see for now (then everyone else will see it and have their "Napster" moment, that one dies and gets "torrented", but the world changes anyway.)
Mostly is that latecomers feel that btc can hardly make another 10X+ from current levels, so they end buying lottery tickets priced $1 or less to have their chance for a 100-bagger, without even looking at the monetary base or any other technical spec of their tickets.
I feel like this is the *real* reason. The delusion these people feel is trying to justify the "reasons" why they are doing it, but they can't ignore the underlying reality.
Also, will it surprise them when Bitcoin does indeed do another 10X or 100X? It will, the only factor is how long it will take. Bitcoin is held by < 0.01% of the world population. Not every millionaire in the U.S. has any bitcoin. Wall Street hasn't even begun to up-leverage Bitcoin, because they don't have a way to do it effectively yet.
