A big wave of miners are coming back, plus a load of new registrations today. had an influx of over 400 miners in the last 2 hours, also assuming other pools are getting some more miners too, so net hashrate is fluctuating too. The most important stats are confirmed/unconfirmed earnings and blocks per hour and those are what counts the most.
Yup. After contemplating what I should mine, decided to come back to Ultra and see where this goes =) Difficulty is 2, seriously?! aha.
