I've been doing some calculations and at the moment it seems that nobody is near ROI with this miner.

If you received it on Jan 1 2015, and you had FREE ELECTRICITY and you sold all your BTC during that price spike on Jan 25 2015, you would have made a profit of $165 till todays date.


But its rare that everybody sold on Jan 25th at ~310BTC/USD and rare that most have free electricity.

Taking the average price using moving averages of the last few weeks and average power rates you would have made only $60 to date with this miner. Why did they sell it at such a high price?
