I have listed with them and their security is useless. They blocked me for a 'security check' and whilst I was unable to access my wallet someone emptied my wallet. There is an e mail trail showing this to be true but they insist that I authorised and instigated the trade. Do not go anywhere near them, you will lose everything as I did.
Do not trust anything to these people. Their security is rubbish. My wallet was accessed and emptied by a third party when I was blocked by their security from accessing my account. There is the e mail trail to verify I was indeed blocked but they claim that I authorised the transfer of all assets out of my wallet.
