Good advice, I agree, but everything happens in the world of cryptography - everything is possible, to say for sure that ICO is a complete fraud - you cant, there are many projects that raise funds just as quickly and pay well for advertising participants
Its way off to support any ICO projects even if any get releases today because there is assurance that they will face problems with fundraising, too many ICO projects exit scam on investors and they don't want to anymore, its better to chose IEO that investors still have interest in
