"the whole damn development is disgusting and contrary to the interests of civilization"
I completely agree with that argument.
Every single funny money scheme is just a blatant pyramid scam where the first in will have the most coins and hope that all the other idiots signing up will make the coin interesting enough that they can get rich off other people's stupidity.
Oh, and some criminals also use it because, apparently, a blockchain ledger is not enough for law enforcement to find out where the transaction goes.
Fail on all counts.
