I think best thing to do is to reinvest ALL of what you get from mining back into mining hardware.
That way you can exponentially increase your income.

but, if you invest everything you get, at some point you do have to stop so you can actually USE the money you made.

It's an interesting dilema.

as for the coins, you would need to get at least 1.5$ per day per 1060, is that possible with current profitability?
