It looks like a corporate scam. And you should not be surprised since the most part of CEX team is really originating from Ukraine and/or Russia. Incorporating in the UK costs as little 1,500-2,000 EURO, so it can NOT be a sign of trustworthy business at all.

Here is a FinCen document for CEX https://cex.io/promo/img/legal/msb.pdf   - has any one ever checked if it is legal or real at all?

Even if it is legal, it states the following:

"MSB Activities: Money transmitter
States of MSB Activities:
California, Colorado, Connecticut, Delaware, District Of Columbia, Hawaii, Illinois, Indiana, Kentucky, Maine, Massachusetts, Minnesota, Missouri, Montana, Nevada, Oklahoma, Pennsylvania, Puerto Rico, Rhode Island, South Carolina, South Dakota, Utah, West Virginia, Wisconsin"

Even if this Fincen document is real and legal, it just allows CEX to be a "money transmitter" in several US states...

So, CEX has nothing like Bitlicense in either country. And this is DEFINITELY a "polite corporate" SCAM from UKRAINE!!!
