Correct, I will reformulate that: if batch #3 arrives with difficulty higher than lets say 35m, they won't even break-even IMO.
You are calculating break even in USD... but the Avalon B3 was purchased in BTC. Looks like it would take about 90 days at 35M to break even with no power costs... those BTC, assuming the average difficultly over those 90 days is 35M (I bet it averages higher difficulty). If there was no risk... it wouldn't be any fun eh?
Yea, if someone paid 101BTC for a rig + PSU + shipping, then it wouldn't break even until they got 101BTC back. How long does it take to make 101BTC at current projections? (85Gh/s)
