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!Indeed some invest even more then 10% and wait for the right time to come and to withdraw and get some more cash.
Some other post have been out of this topic but no worries.
