It's a gamble on what the landscape will look like in march. My take is that 100GH/s will not be that much. And you will have nothing else to do than wait all that time. Just buy yourself btc atleast, you can always exchange it back to fiat dollars if you want.
*edit Paypal, lol. Do more homework. People around here with good rep do not need paypal at all.
This is your best bet
