fees for s1 miner are over 100% so is it a negative return?
exactly ... you just lost money day after day... hashnest.com posted the following:
As the earning of AntMiner S1 on HASHNEST is nearly equals to the Electricity + Maintenance fee, there are 2 solutions for discussion:
1. HASHNEST will process the AntMiner S1, and the residual value will transfer to BTC, then, equally share to every S1 users.
2. Transfer the hash rate of the AntMiner S1 to UMISOO under the ratio of 2:1, and the residual value belongs to UMISOO.
I don't know for how much longer this is going to take for them to finish, but it would be interesting to see what option they choose and what's going to happen afterwards.1. HASHNEST will process the AntMiner S1, and the residual value will transfer to BTC, then, equally share to every S1 users.
2. Transfer the hash rate of the AntMiner S1 to UMISOO under the ratio of 2:1, and the residual value belongs to UMISOO.
