Thank you for this thread.
I decided to go into mining yesterday and was just about to check out my shopping cart for two rigs with 6 GPUs. Your post let me re-think about this, because I havent thought of the difficulty development yet and just calculated with the current value. (Yeah.. i'm new

). The price per kWh is actually much higher here, so this business would start generating loss in only 30 days or so.
So looks like I missed the boat. Any other boat on the horizon?
