Thanks for your helpful review. The development team is certainly impressive, and it is very good to know that you have gone far beyond the "Whitepaper stage" since you have an alpha version the public can use for tests.
When you say, "ENG tokens are native currency of ecosystem", do you mean that in the ICO stage we do not have to purchase ETH or some other token for submission?
When you say "ENG tokens will be used to pay for the premium data sources which will provide high-quality data to assist trading", do you mean that the system will deliver data to quants and the quants will pay in ENG (instead of US$)?
The following is a concern to me: "With Data sources, the traders will be able to access premium data streams which are concentrated specifically around cryptocurrencies." It seems to say that the data that will be available are trading data and nothing more. I would not want to program my robot using only that information.
RE: "The profit generation comes from the appreciation of the ENG tokens due to the demand on the secondary market." I suppose that "appreciation" means an enhanced exchange rate relative to US dollars, so that US dollars become the standard of value. Is that right?
Cheers!
