for now most ICO scams. my advice you don't need to join ICO. if you want to know that the ICO scam is a fake team, there is no ANN, there is a minimal whitepaper and also an inactive telegram group.
There are a lot of talks about ICOs as about scam things. I don't think that this is right position. There is statistics that says no more 10% of all ICO projects are profitable. Keep that fact in mind when you are going to participate in ICO.
