Remove coinmarket.io from the list of exchanges. It has been confirmed as scam.
I sincerely hope they are not gone. I had 5 Mill Noble on there I have yet been able to withdraw. Please baby jesus don't let it be true.
I managed to withdraw my coins 7th of March, blockexplorer shows transactions for both BTC and NobleCoin. (didn't verify otherwise that they came as wallets are both offline)
