KNC Jupiter 550gh 0ct 18th 2013 till now ....very very close to getting 50 btc out of the beastie!
Interesting so the BTC profability per $/Watt has moved as follows from FPGA to ASIC:
Hardware: 0,075 to 0,005 BTC/$
Electricity: 3,75 to 0.06 BTC/Watt
That's a factor x15 less for hardware price and >x60 less for electricity cost. O_o
Lets push that difficulty a little bit more!
Remember: if you heat your home in the winter (not overheat!!!) with mining; ROI does not matter!
Hell you can even run old ASICs at a loss, they will always be less expensive than your radiator!
Agree on the last part that ASIC is better then radiator, but my family don't like the ASIC smell, dont even know if it is hazard.
