Near as we can tell, we had a run of bad luck.  We are looking at it more, but don't see that anything is (or was) wrong.  Now there are a bunch of new blocks maturing, with no changes on our side...this will get worse as difficulty rises and variance becomes more apparent.  We are planning to create a private pool so that we can pay out the 500TH shareholders on a more regular basis.  Not sure when that will be ready, but we've got most of the work done.

As to the question of whether we will expand - it has been stated many times, very clearly that this was a fixed size project.  Initially it was 100TH, but Tytus expanded it 5x to try to give a good return to investors.  For early investors, the mine has hit ROI weeks ago.  For investors who would buy shares now, I'd have to say compare our price/GH to that of cex.io and make your own decision.  Comparatively I think we have a good price/GH for leased hashpower.
