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.

Scam ICO is and will be the worst Fraud Schemes in existence today, its irresistible but only in few cases. just like he had pointed out those points. its better you invest in already made coins. like in the top 10 to 20 ranks. just be careful in decision making regarding investing in crypto.
