This is real scam - deposit working - recieve coins in Exchange wallet in 5-10 min. but no chance to get withdrawal. All withdrawal go to unknown destination - no any data in blockchain. They just steal all withdrawals.
I just looked around the net to find some info real quick about this for you and came up with something useful.
Check this subreddit here:

You will see that some users HAVE received their withdrawals, but others complaining they have not.
This thread seems to have legit members that have been swindled by Cryptobridge though. I would stay away until further clarification just to be sure.
I did a trade of 528 PURE coins on that exchange and everything worked well. However, there is something behind to make it a DEX and thus made me confused at my first deposit. Anyway, my first trade worked well. To be honest, I want to invest more on some rare coins on that DEX. I will come back next week....
