Its pretty simple with ICO's even if you are a newbie.....do you research and research and research before you put a dime into the company. Yes the campaign manager being legit is a good sign but NOT the only thing you should look for. And if you think the research takes to much time, just invest in ETH, NEO, or other solid alto coin while you are researched ICOs....will save you from getting scammed everytime other than if a project fails.
