^^If this guy is telling the truth, and I am not sure that he is, then the person who is behind hashocean was likely laundering his BTC via various DNMs and was using coinjoin transactions to obfuscate both where his BTC came from and where his BTC was being sent to.

^^the txid that this guy posted however is almost certainly a withdrawal transaction from BTCC.

^^I believe this guy's transaction was also likely from BTCC.

I would say that if you believe the later of the two people I quoted then the owner of Hashocean was depositing his own BTC into BTCC and subsequently paid out his users via a withdrawal from BTCC.

If anyone else can post a txid of a withdrawal of their BTC from hashocean then I can look further into the situation. I will most likely ask you to sign a message from the address you are claiming to receive payment to.
