Escrow on ICO’s? I think its not possible not unless you are talking about signature/bounty campaign. It’s still hard to avoid scam ICO’s because even they have escrowed bounty campaign they still failed on their project after that, so your money will be loss for good. There is still no guaranteed profit when you invest on ICO, for me its better to buy token after listing on the exchange where token is more cheaper than the ICO price.
