fees for s1 miner are over 100% so is it a negative return?
As the earning of AntMiner S1 on HASHNEST is nearly equals to the Electricity + Maintenance fee. After discussion, we decided to transfer the hash rate of the AntMiner S1 to UMISOO under the ratio of 2:1, and the residual value belongs to UMISOO. It will be done by the end of Sept.
