I've been using it for more than a week and I can already say that this is going to be a major player in the exchange market. Good UI and UX, no fees, they are going to be adding monthly new tokens to the exchange.
Maybe it's a bit slow in order to verify account, but I guess it's because registrations are surging right now! 🚀
PS: If you see weird prices in BTC or ETC against USD is because basically there is no volume there 😅 In order to deposit fiat currency you need to be level 3 account and not a lot of people has been able to do it due to the speed of the process.
Scalability is always challenge as we see slow some times, verification of identity has to improve.
It has the potential to be an industry leader; Before qtr 1 2018 ends, CobX will surely grow massively
I joined this project before they launched, and have been actively involved in their community. Can only recommend this exchange. Lots in store this year!
