CoinExchange is only as reliable as any other exchange like YoBit, they can control all matters and the Moderators are their own law.
The Moderators are serial Blockers, stopping ordinary people from commenting on the otherwise healthy Troll Box, for less than one minor discretion. But they also have the power to Block your entire account at any whim. They will also create their own rules to help their friends on the site draw your fine earned monies away from your wallets.
Be very wary of depositing or withdrawing ANY funds from CoinExchange as the Moderators can block these as well - and once they have been sent will spend all of time in an existence where, you, the originator can't access them.
You have been warned about CoinExchange. Tread Carefully and Warily with them.
