the problem even if they are real when they want to scam you cannot do anything about that.. i know some projects that did like this but after all they were all scammers. the project was successful in their ico but in the end, they end abandoning the project and their investors
There have been many projects like this in the past and their strategy was initially very impressive and attracted many investors to participate but after the sale was completed, the project disappeared very quickly. That is why I am afraid to invest in ICO projects because there is always a risk when investing. Now IEO is becoming a more upgraded version and can guarantee you liquidity if that project is IEO at big exchanges.
