helo Kano, i was start mining with antminer s7 2days ago, and i got great BTC than any pool, but i need your suggest about worker management , How much minimum diff should i set ? for best setting in this pool
Thanks

Leave it for the pool to set. Ck did a post about this. It doesn't make you more money or anything and if you set it too low the pool will automatically set it to the pool min anyway.
