Poolwaffle, I think you should experiment a bit on this ghash.io bonus situation, even if it is only out of intellectual curiosity.  I realized that the 15GH/s whale has the most control of anyone over the current hashrate at ghash.io, and I've noticed that it is staying just below 40GH/s which suggests that he may be lifting his foot off the pedal to do so.  Even if he has to reduce his participation there to 5GH/s, he would still be earning a 33% bonus over his entire 15GH/s under pool hashpower 40GH/s, which is considerably better than the alternative 25%.  So if you push the pool's pedal down a bit, he should be very willing to lift his up a bit.  Of course, you just need to be able to handle some of his hashpower returning here, and not just send more back there as a result.  Sound interesting?  Think of it less like a game of chicken and more of a dance if you prefer.  Just don't let him lead.

And it is quite convenient that cherry picking doge blocks is still an option while this promotion is underway...
