That is a brilliant question!
Instead of all the endless bickering between crypto-fans and -haters reaching from technology to fiscal policy to society, it reduces the conflict to one simple test, as a sort of precondition.
Anecdata, but just going through my set of acquaintances, personal profit was always a factor. And I never even thought to question it. In hindsight, however, it seems (1) such an obvious thing to do, and (2) makes it clear to me that my acquaintances probably wouldn't give a damn about crypto if there wasn't a chance to profit from it.
I mean, the only reason Bitcoin went mainstream in the first place is not because of the technology (which existed for a decade), but because there was a extreme bubble (again) and mainstream people wanted to get rich quick.
