Well, block percentage for last hour went from 200%+ to 0%....as well as all last hour stats. Doesn't make me feel warm and fuzzy about mining that right now. Glad I dropped it when I saw it was at 230%.
Hmm, dropped it as well for now. Zclassic wallets are in maintenance in bittrex so I'm not sure if all this issues have got something to do with that also. Another thing that was going crazy few hours ago was myriad-groestl difficulty and ccminer. I know the admin is doing his absolute best but these kinda issues are really bad because the cumulative effect of mining difficulties is really damaging for a pool's hashing power which is the main incentive for any pool.
