Just after a very short time running a ASIC will be profitable with free electricity only.
Team up with a student in a dorm room or a single mom in a state-sponsored house LOL

Unless I messed up the numbers a Jupiter with 350 GH/s and 1000 W power consumption, should turn a profit until difficulty is over 4 Billion. While the extra profit of no electricity cost would be nice, I think I'm good for a while.

I think you fucked up. My calculations say that at 1.5 billion difficulty the Jupiter would not turn a profit even if the price was 350 USD/btc

It's really simple math:

1000w at 0.2kw/h are 4.80USD per 24hour
At 4 billion difficult his 350GH/s would be producing 0.044BTC per day.
To b/e on the electricity costs the price per BTC should be $109ish

So, theoretically he may be right saying that Jupiter "should turn a profit" at 4 Billion diff... But practically speaking it's nonsense IMO.

What is the point/premise of this discussion? 4 BILLION diff isn't exactly 'around the corner'..
