OP, you cannot say that words! The listed exchanges could encounter security issues or some unexpected problems? You trust them and have your reasons, like existing long, good reputation, responsive customer services etc. So you can trust them but don't keep most of your money over there! You handle over your money to others, there are risks associated!
