honestly I have no idea its scam or not but my personal experience with this exchange is not good they took weeks sometime to show deposit into your account after days of support chat finally I received my deposited tokens into my account so you cannot trust such type of exchanges blindly.
So if they took weeks to show your deposit in your account that means they are not worth trusting. The reason they took time to show your deposit is probably because they leveraged your funds elsewhere.
Beware of the scammers at coinsbit and p2pb2b
