Your best bet would be to pay for hashpower for Bitcoin mining from Genesis Mining or Swiss Gold Global when it's available. I've got 2TH/s worth of mining starting on 28th February next year. Should bring me in over $200 worth of Bitcoin every month. They only sell pre-orders for Bitcoin hashpower every now and then and it doesn't last long so you have to keep an eye on their sites and jump on it as soon as you see it available.
