I wouldn't call them fools, but rather "investors in the matrix". What they all do (buying bonds) is a familiar and conservative way of investing, which until now "worked well". But times are changing.

For you, bitcoin is a "lifeline" to escape poverty, and for the rich - a risky and unclear asset, which, by the way, is practically not regulated at all, and therefore doesn't provide any guarantees of investment safety. If something goes wrong, who will compensate the rich for their losses? Nakamoto? And in the case of bonds, there is probably "protection from the state in terms of refunds" (although this is also a controversial point).

You are ready to put your $100-1000 on the line, and the rich will not risk $10 million. This is a different level of responsibility, so their motives will remain unclear to you.
