Here is lot of iCO. How i find legit ICO.
No right way to find out legit ICO. Most important factor to avoid scam - it is to investigate team of the project and try to contact with team members via independent contacts. Don't use contacts on ICO site, because it could be part of scam scheme. If you are have confirmation that team members are real and you trust to this people - it is good ICO for investments!
You are absolutely right, there is no way to find legit ICO, even though they might have good and solid team, it's not a guaranty that they will do well, i have join an ICO that had best of team but they are doing very poorly at the moment, so joining an ICO is risky and that's more reason it is good to invest with what you can afford to lose.
