ouch... new difficulty 15605632
Jp 28,4% increase... Best I can think of it that Butterfly labs are "testing" customers ASIC... Since I don't think that there was any big ASIC shipment...
Except all the USB erupters...
There are only 300mh and they are not that many send out jet... To get that you would need 156.800 of them... No way... Or 4000 blades... Again no way...
Yesterday, one (or more) ppl have become from BTL 5ghps miner. They have posted on hungarian bitcoin forum. Have tested too and work fine.
So 8500 have BTL 5,5 have been send out... That would explain that increase. Or am I making some error in calculations? And they would need to be online for the whole time. Not just last days..
