Wait is it scam because national coins, that is not national any way, were not developed by nationality is doesn't represent any way ? Or did they actually are real scamers. I bet clients using those coins should be aware of it, but i'm not sure if it really is a scam.
Whenever you don't know how it works, it is probably ponzi
People who invest first get they income from money other people invest later. It is pyramid so dude on top gets a lot of money, dude on bottom lose all. If it were normal fund, this dude could go to jail for it.
Well whole point of altcoins is decentralization. Making any kind of cleanup would take some people who decide they have authority to do something like that and make decisions because they think they are wiser then others. This would corrupt entire idea of freedom and decentralization. I don't oppose the idea completely but I just think it is too radical.
