It's actually brilliantly structured if it is a scam
There is no
IF. It is a scam!
There are many scammy ICOs but most of them are not decentralised
All of them are "Decentralized", non regulated and scammy. That's why, all ICO's are banned in Chine and in US. (EU countries to follow very soon)
I agree with you, except for saying it's decentralised. Bitconnect is not decentralised and neither are those other scams you mention.
It doesn't have to be a government for it to be centralised, it just means either 1 entity or a small number of entities control it.
