This would be the best way to earn Bitcoins: Get a job and take out 10% of your earnings and spent them on Bitcoin. It always works for me

10% of your income is not bad considering many people do not earn over $100,000/year, which equates to less than $10,000 invested in Bitcoin. That has a lot of potential to grow, considering the very low prices of Bitcoin right now. Great time to buy Bitcoins!
Yes! Low prices means a good opportunity to buy a few Bitcoins. I still can't wait for Bitcoins to get to the moon. I think that the $1000 mark will reach in 2016, maybe?
