Look -m even billionaires are dumb fucks.  "I changed my mind about crypto.. I don't know what the fuck it was but now that I changed my mind about it, I still do not know what it is."  In other words, he does not know what he changed his mind about, and if anyone interviews him to find out what he is doing exactly, I hope that they can at least get him to describe what he might be doing (that is different) beyond vague ass concepts of changing his mind from one amorphous thing to another amorphous thing.
