It's not familiar . But base on my research there are some negative feedback about it.  Wherein users saying that after putting money on it they suddenly encountered an errors, and after how many time trying to contact the support they are now block and unable to retrieve their money.  So probably this is a strong proof that cyptobridge are not trustworthy exchange. So stay away on it mate because no need to seek some sort of explanation and moreinformation  . In fact i brought the link just for you here it is (cryptobridge).
