We did not talk with coinexchange.io and we cannot officially endorsed them! We have been talking with an exchange, but it is not this one.
You will be able to trade KMD in an exchange we do endorse within 24-48 hours!
Be careful when trading in unknown exchanges, and do not assume we are behind it.
Also be aware of scammers, there are tons of them. We would never ask your seed or any other private info! Always double check with whom you are talking to.
What do you mean by "not not talking to them"? I saw James and other dev helped them to fix some issues on Slack before they've added KMD. That was talking )
