I have an antminer s9 and an antminer s9j, I would like to know which is the best pool I can put them in to have the best performance
Slush pool or know as now Braiins Pool is very suitable for S9 antminers However, I think S9j is much more higher in TH rather than S9 if I am not mistaken. Like in S9 there is 13.5TH while in S9j was 14.5 TH, and in terms of price S9j is much cheaper than the S9 miner.
But of course, you can do your own research about this matter anyway, this is just a suggestion and comparing in between
the two miners, here's the
