Cryptocurrency exchange Okcoin is a good trading portal for large investors. Here, the crypt is much more expensive than on other platforms, which causes more interest in making money here. There are not so many coins in circulation, which is frustrating - one could add, users will appreciate it. The interface is simple and clear, but the language support is weak, only English - because of this, some functions located on the site may not be clear to everyone. As far as security is concerned, everything is in order here, it is reliable. It is immediately clear when registering that the team cares about the safety of funds - the latest security technologies are used. Technical support is in touch, copes with questions and problems of users. My conclusion is that the Okcoin exchange is profitable, but boring.
