Tell me if you have accidentally won the bitcoins would you still send back to freebitco?

They have not forced you to bet your whole amount of money. After seeing the screenshot I am wondering that you have risked all your money more than 62k USD$ for 1.01x which is roughly some hundred. By seeing your bet it shows that you wanted to bet and win from it just that amount. I don't understand the reason to bet that amount.

I do not think they are going to return you any amount because you bet yourself purposely to earn some hundreds.

Claim 0.065 from freebitco. You would've easily earned money from 6.5 bitcoins by investing in some other things but you decided to bet now you want return I do not think so you will get.
