The tag clearly says "BtcSmart - Multiply your money" and yet you link that to AM? Are you really that stupid or do you just think everyone else here is?
And what happens if gen4 misses efficiency specs like gen3 did? ASICMINER is dead in the water.
If AM miss the specs but the chip is still competitive then there won't be a problem. If gen 4 fails to be competitive though then yeah, AM is pretty much dead in the water.
