Please stop spamming me with trade offers and low price offers, the price is set to .409BTC lower offers will not be accepted.

180Gh/s miner with price 0.409 B = $248.4
let's calculate :

per Day   0.00672406 BTC   $4.09
per Week   0.04706841 BTC   $28.60
per Month   0.20466352 BTC   $124.35

1 unit miner with 180Gh/s can't ROI in 1 month and electric cost?? are you thinking about it??. and difficult always increase every hours, day and weeks. This is unusable.
at this price, we will just throw money down the drain.

don't forget the miner is still worth something at the end of the month. Additionally you can mine other sha 256 things and make profit there. There are too many variables to just say hey it is going to make X amount in 1 month it won't roi.
