I definitely empathize with Saylor in this clip. So long as Bitcoin is seen as an investment vehicle, people will naturally assume it's crazy to "go all in" on it like some kind of madman.
But I think it's because we have to manage a plethora of money substitutes to make up for fist currency. If Bitcoin is just another money substitute in that point of view, we all look like a bunch of extremists or idealists or cultists for picking one over all the others.
It will take a long time for people to come around to the fact that Bitcoin is just money. You don't need to diversify money.
