Okay, so just because a person has created an exchange does not automatically mean that its trustworthy. Anyone, can make an exchange, and there's even various white label software out there now. Before, using an exchange you need to ideally do extensive research on the people who are behind the exchange, because they may well be the same people you are trading with on this forum.

Regulated, and registered exchanges are usually the ones to go through, as they're often governed by laws, and other regulations, but ideally you should be taking a look at the customer reviews that people have made, and even then that's not always a good conclusion as there's various bias' that people can inject in their views, and reviews of the service.
