I thınk you can't avoid scam ICO's if it is in your faith 
because they can look legit and after six months past of their ico they can say we are done we can't deliver this product because of this because of that bla bla.. You can protect this situation with blockchain or nothing else. If you are not a risky person you need to go on with BTC LTC and Eth or really good proven altcoins.

With this kind of scenario that cannot be avoided. So you need to be smart enough and think about the future. About the potential of growing of an ICO. It is not just about the present situation and the proposal but we also need to consider if it is attainable and realistic. We all need to be smart, but being smart is not enough sometimes there are still luck.
