Very advanced technology of business implementation through IEO. Participants do not send money to a smart contract, such as ICO manages. Instead, they must create an account on the exchange platform where IEO is held. Thanks to the many guarantees from the exchange itself, the participation becomes safe and profitable.
I do not know how the provision of personal data when creating your account can affect the development of new projects. It seemed to me that the problem of the market of ico companies is precisely a large number of scammers, and not other problems. Providing passport data does not solve the problem.
