Ive stuck with mining Qubit as well.  The blocks Factory used to be pushing almost 3GH but since the price has gone down its fluctuated alot.  There is one big player with over 2GH of power.  I really wish i knew what they were running...

The past 2 months of mining have been pretty difficult, even though we have 5 algos, I only have 1 small rig so the big guns still sway the difficulty a ton.  It is nice to see Digispeed working so well though.
