Gandalf86,
as you seem to know everything about espers. if the espers wallet statistic says: 265.000 Mh/S, does this change anything about the mining? Because mining didn't really seem to work today.
It only means you should go mine on a pool instead of soloing. Unless you have massive gpu rig, but even with that, you still should pool mine.
I am mining as member of minertopia pool, but yesterday the rate harshly decreased. what is the reason for this? I don't get the difficulty stuff and the net hash rate seems to be close to the mining hash rate of minertopia.
