I'm surprised people are still so bullish on SELLING when difficulty is currently scheduled for a measly 0.6% increase, which is far below the threshold required for selling to receive a dividend.
Most difficulty predictions are based on the average hashrate for the period since the last adjustment. For most of that timeperiod, ASICMiner has been running with significantly less hashing power and they've only recently recovered. Consequently, the average hashrate since the last adjustment is relatively low and will rise if there are no other hashrate-drops.
