Start to speculate about QoinGrow.com
My opinion is that you should sign up as you read this, it's currently just at investment level 3, and will go on for atleast 10 more levels before it will be difficult to get that many investors to level up the investment level, I think.
Raise your level by sending Bitcoins to your personal deposit address and making a deposit check at the same time. Wait for the Investment Level to level up, you will then receive Bitcoins that you can choose to withdraw, or reinvest to raise your level. It's recommended to reinvest some of it and withdraw the rest, most recommended is to split 50/50.
Seems legit!
