It's probably not just about when you start mining, but what you mine.
And about what profit you get in the end, still there too low bitcoin economic activity, they are not get used as regular currency. So I prefer to calculate exchange rates of pair bitcoin-USD and after - withdraw, Hope soon bitcoins go after 900 USD, hope this graphs be useful http://mining-profit.com/bitcoinAt this stage, the 900 USD looks less viable every day. By the time it reach those levels again, my "cloud mining" profits would have been absorbed in maintenance fees.
We are all hoping it reach those levels, so we can show some ROI for our efforts.
