If you give me a 10 BTC i work harder to double your amount 
and I'll sent you back as a double amount. Or if me on your situation. I should to invest that to trusted investments sites. To double your amount of bitcoin. And be careful of your investing on the other sites. Because most of them. but much better to you must be withdraw that. For because that kind of amount is big to convert a real money.
