Hopefully, hashing rate will become more stable soon. I think we can anticipate another reduction in around 8 days, to leave us mining around 30 coins per day. If Bitmain then release another batch so after that, it will really impact on earnings, and may affect the trust early adopters have in Bitmain.
Bitmain has just sent me the tracking number of the second batch B3, so probably another difficulty increase can be expected already tomorrow.
