In November I broke even with 50 GH in two month.
In December I am half way with 200 GH.

So I expect:
In January you break even with 800 GH.
In February you break even with 3200 GH.
In March you break even with 12800 GH.
In April you break even with 51200 GH.

I personally would buy the coins and wait.
The price of the bitcoins will not rise, until people start buying bitcoins.
Mining coins decreases the value because miners will only sell or reinvest.
