Skex exchange is one of these exchange which has been up for some times but went off in a few months. The exchange has been able to keep it's name going on the social media through various telegram not airdrops which never came to reality or never pays off. It is recommendable for you to stay away from the platform as it is not a save place to be. The exchange is currently not in operation and anyone could be claiming or getting information from users and might end up in havok to users who provide sensitive information. Keep your head up and look for other exchange out there as a lot of them are available and there is need for you to make a careful choice
