I think Neon Exchange (NEX) is a good project in July, it is a Decentralized Exchange like EtherDelta, IDEX. NEX is a version of Decentralized Exchange that is superior to all current versions. also dav - origo network & EON seems next huge icos.
it looks like a coin about the exchange, very promising in the future, with more advanced innovation can compete to make it big exchange, i think the product becomes the main reason to analyze it
BNB token has proved that this type of tokens can succeed, but if I have to choose an exchange token, I will choose popular exchanges, because they make huge profits that reflect on the token price, I will keep an eye on Huobi token as it is reputable exchange with high trading volume.
