A year? the ROI for that would be like 5 years - you over-estimate the profits currently. It was profitable back in March far more than it is now - the gold rush with mining is over.
Sure, but how much crypto currency are you going to get out of it from a pool? if you get 8.1 cents per hour, well that's not exactly that exciting.
I've been a miner for years, and I'd recommend you take a look at your expectation of profit, it is profitable still, but get ready to be disappointed.
