I've made two withdrawels on the 24th of december worth ~5 k$ (Moon coin) that is shown in the status of coinexchange.io as completed. It is not shown on the blockchain. I've made a support ticket the day after and after a week or so they replied that all issues with the moon coin wallet are over and all transactions should be prosessed and they closed the ticket. I re-opened as the coins were still nowhere to be found. A few days ago they closed my ticket again without any comment... they replied twice to my tweets stating there was wallet maintenance and that my coins would be returned afterwards.. maintenance was a few days ago and the wallet is back online and working fine since days.... yet I still don't have my coins.. and no reply to my ticket!
Looking at the number of people having issues with lost transactions over the internet and twitter etc, I am really starting to think they are scamming people by draining random small transactions.
I do hope I am wrong and that they are simply flooded by the huge number of new users etc and that I still get my coins back...
