How do the S5 customers feel regarding the fact that BITMAIN is testing tons of miners on the live network right before shipping? I see a sharp rise in the difficulty right after the S5 announcement.
This is a pretty big leap in logic detective. But let's assume they are "testing" before shipping. As long as they ship when they say are going to (unlike BFL, KNC, etc), I have no problem with this. I would rather they run it for a few days. Fewer duds get shipped that way.
