So today difficulty has MASSIVELY dropped on equihash coins, not sure if this is just related to the nicehash hack (or maintenance, or whatever is causing it to be offline) causing a large pool to drop out?
Look at these numbers I'm getting for my rig's specs on whattomine:
-50%(!) difficulty on BTG, big decrease in zencash and zclassic too. Sibcoin has to be directly related to nicehash as well since X11 can't be that popular a algorithm to mine outside of nicehash randomly switching to it.
