There is an ICO head office where you can make complaints
I thought this was legit but you are talking with a different meaning for ICO. As for DooMAD, you're giving a wrong service to OP.
ICO's are decentralized and there's no head office or governing agency that is regulating this if someone has a complain and this is why everyone must be careful of investing on it.
That's right ... but i have seen that there are ICO escrow companies. I havent looked into how extensive they are, but the idea seems legit. If they are credible enough a company like that, can be your seal of quality assurance.
I don't know much about ICO escrow companies. The idea seems legit? you just heard it and share it here but you're not sure if its legit or not.
There are real escrow companies (bank,etc.) but about that idea of ICO escrow company? What's the point of their service? SEC implements regulations about ICOs but with that service, I don't know.
