Crypto is a more direct way of saying "fuck you, pay me". This is why it's currently less popular (although this will probably turn around when it becomes "fuck yeah, pay me!"), but the no-bullshit transaction going on is that something of value which can't be spoofed is changing hands. The benefit of that is that you're going to think very hard about what you exchange for that. (Well, eventually, once all the idiots have offered up their money for scams.)
