I just did back up for one of my miners and Hashrate went back to 1160

but after I have added the f2pool address (without update), Hashrate is still falling down. Is it normal?



stratum+tcp://btm.f2pool.com:9221

btm address

pass




who knows what is going on? help me out guys, please.


P.S. is it true that I do not need to register with f2pool to mine B3? Im just writing info as mentioned above and that's all?
