People who believes that the site was hacked then you're out of your mind, this strategy was planned already of nicehash team, as the bitcoin price soar ($14k at coinmarketcap) and of course its a big win win to them everyone will believe if they will tell the world that they were hacked using those huge media/news site, and now its time, they published that were hacked? Com'on, this is not common thing, hashocean moved that way too when price is in the middle of surging high.
Something is fishy for sure...
https://bitcointalk.org/index.php?topic=2537271.msg25881770#msg258817701. BTC price its at a alltime high. Good time for an exit.
2. To put all btc in one wallet is just stupid. Even with the slightest security thinking you can realize that.
3. The internal adresses was probably linked to this wallet. And is a strange system in itself.
Myself I was about to get payed a bit over 0.01 btc the 8th of December. It feels fishy this happens just before.
