Well, you just answered your own question.  I'm here, because crypto currencies are potentially a way to "hide from the man" (I'm not going to "battle" the man, that is a hopeless affair ; but the man being evil, I try to find ways for people who want to, to hide from it ; if enough people do so, the man becomes powerless ; but even if a lot of sheep let themselves screw by the man, those that want to hide from it should be able to).

I already told you that it is the *only* utility of crypto.  If you don't want to hide from the man, the man has much better currency: fiat.  Use it.  There's no need to get into the hassle of crypto, fiat is much better.  The principal problem with fiat is that it becomes very difficult to hide it from the man, and that's where there is a potential for crypto.  The only potential, apart from a greater-fool game.  I'm not sure that the potential will play out, but if it doesn't, crypto is a totally useless affair.

The other reason why crypto is interesting *as a study object*, is that it involves hierarchy-less dynamics, which is of course what you get in society if ever it can get rid of "the man".  A question is: will in that case, a "new man" rise up ?  (centralization).
