My tip: Do not invest in ICOs. ICOs are not as much profitable these days compared to last year. If I were interested in a certain ICO(though extremely unlikely), I'd probably buy it after the distribution instead, as prices are sometimes lower after the coins/tokens are accepted on exchanges.
I agree with mjglqw and now ICO projects rarely use escrow and maybe now almost none.
Escrow aims to avoid investor funds being taken away if fraud occurs
