At least project IEX has every chance to succeed. In addition, do not forget that the project offers the possibility of using exchanges without any verification of KYC, which should also be interesting for many traders and investors.
This should interest first of all those who care about their privacy. Such people among the crypto community is not enough. I think that the service will be in demand.
Now in the crypto market, many investors are in a depressed mood. Many suffered losses last year. I think that in such conditions it is very difficult to develop. I hope that the team will be able to bring the matter to its logical conclusion.
