uhmmm ... Understanding of Bitcoins mechanics makes even smart people feel dumb!!! Trust me!
Try for example to explain to medium Joe what weird shit is happening out there, with the fork of bitcoin and the creation from nothing of a mutated clone of itself called Bitcoin Cash.
greed of people will do the rest?

uhmmm maybe yes, but the people who are betting their money on cryptocurrency arent really understanding in what they are putting their money.... IMHO they are nostalgic of dawn of the internet era and of the early 1990 tech bubble... hoping that it will repeat itself with Bitcoin, Ethereum, and the rest of the cryptocurrency.
But the spirit of early 1990 may not console investors facing losses they cant even understand.
When events like last hard fork remind people just how little they comprehend when it comes to how Bitcoin actually works, Bitcoin doesnt have a lot to fall back on
