Good luck,
how did you calculate your break even? Which assumptions did you make regarding the increasing difficulty?
For info, I do a little mining (BTC only), and so far - after 3 months - I got back app. 20% of what I have invested. The daily return decreased app. by a third, as did the Bitcoin price increase. I am assuming that in case the Bitcoin price stays flat, there is no chance to ever break even due to increasing difficulty.
Generally I would be very cautious about this business model.
