Im sure that Project IEX has professional marketers in it, and for sure there is a substantial budget for the promotion of its project. Because we all know that at present marketing is a higher priority than technical innovations that most projects offer.
Alas, this is the reality of today's crypto market!
You're right. No matter how promising the crypto project may be, but without strong marketing it will not survive. Even such a promising project as IEX needs marketing support.
