all of the sudden my antminer s7 drop on the mining pool and nicehash from 4.7 to 2th and to 1th and to 2th agen but an the miner page all is ok. any advice th how to fix.
do not mine on nicehash.
or do you want the long explanation?
here is the long reason it happens. you are renting your gear not mining with it.
So multiple switching occurs. At times the s-7 can connect and disconnect a dozen times in a minute. As different people rent it. So your rate can jump all over as it switches.
lets say you are mining for one of the two guys in blue high lite.
Some one could pay more and you switch out. the guy paying could run out of rental money you switch out.
many other things can happen it is a long list.
