Just a reminder, ROI is Return On Investment. It does not mean Profit or Break Even. Your Return On Investment can be less than your original investment.
I don't get it. If you're not planning to profit from mining what's the draw? Difficulty would have to do an about face to make your mining equipment even hold value and the makers are pumping out more each day undermining it's value. If you're looking strictly for BTC to go up to get ahead, stop buying mining equipment and start buying BTC.
Asics is disruptive technology. Scrypt-N based coins such as vert coin are asic resistant so makers can't increase the difficulty so quickly.
