Probit is batter than Latoken and p2pb2b. They are not good exchange for IEO. There have no successful projects. I don't know why team select this exchange for IEO. At present people are not interested about this exchange.
Well that’s also those IEOs’ fault that they are not successful. Market making, for example, is their responsibility as well and an exchange can do nothing if the project doesn’t work on it. Regarding Latoken, they do help projects with KYC, secure wallet, landing page etc. and they do projects scoring before accepting them. But any exchange can face some difficulties like non-performance of the provisions by the projects.
