Unfortunately mainly because of both chinese miner factories not working/shipping for two weeks or more,
I WISH I AM WRONG, but with few zillion of S7s more (at 720$ atm) I am afraid we will be back to jumps very soon
(even one drop in diff is good, but it would be nice to have it steady at least for one month...)
But it does not change the FACT that if you mine then KANO IS THE BEST POOL YOU CAN MINE ON
