BITMAIN only sold limited AntMiner S1 to Bit-Mining.Co, there is no any partnership between BTIMAIN and Bit-Mining.Co.
If and only if we see enough paper works from the police or other regulation entity, we will provide all the info to legal enforcement entity.
Thanks for the info Bitmain I just got 4 of your S1 miners and am very pleased so far. Luckily I actually made btc at bit-mining because I kept pulling my profits daily. They only got away with like .1 of my winnings.
