Coindeal is also promoting themselves as a fully registered and regulated crypto exchange if that is true then definitely its token is worth investing because not many exchanges are properly registered and licensed, regarding low volume i think that will grow with time at the moment the exchange is just building up and want higher user base.
Yeah I also noticed that they're marketing it that they're fully licensed. Due to regulatory rules, they've limited their exchange to some country. And not whole USA is covered by them. They have their exchange service in 13 states in USA. They're trying to expand it.
So my question is should I invest in CDL?
If everything goes well then your investment would be worth mentioning. But I suggest you to invest a little part of your budget and make investment in BNB, HT etc.
