To big a gamble to stake way over $12k on. Good luck though, I admire your balls, and I thought I was risky putting $900 into 3 x BFL 5 g/h miners (15G/H) to arrive this side of Xmas.
I've calculated I will make back the BTC spent on this outlay within the next 120 days, even accounting for difficulty increases (And to be clear, am reinvesting previously mined BTC accrued over the last couple years)
Am OK with that.
