shows that this 120Gh will return only about 35 BTC in a YEAR
so what's the point of paying more ?
So why are you browsing the for sale section looking at mining machines? I just showed how I am far cheaper than other options available. Aren't you wasting your time? Oh...wait...maybe its because you think enough suckers will fall for the paranoia and all these ridiculous comments and lower their prices. And because you are willing to pay to get one. Otherwise stop wasting your time and leave this section with prices out of your league.
And do you actually even own a machine? Even my BFL Single makes half a BTC per day and thats 15 BTC in a month and used to make more. Wow...it must be a special machine to generate so much BTC so fast.
Dont forget BTC scales with difficulty. Did you account for that? And if BTC is 300 at the end of the year, what does that mean? its more than doubled its efficiency.
