I see a lots of ICO with the use of their coins are similar. They raised money, got them and ran away.
I don't think so even though it is actually the comparison of scam project is more than the exact project. there are actually still many projects that are not scam or failed. however, I confess that nowadays it is difficult to find good project that are not scam or even failed. as my experience, I have done some projects that are scam and failed. I just do nothing about the result.
