I suggest investing on some legit and trusted bitcoin doubler websites. You can find some in this forum which you can trust because many of the users are being paid by them here.
There is no such thing as "legit" nor "trusted" on bitcoin doublers as we all know how those ponzis will end up. It also doesn't mean a program is trusted if they are paying their investors, it is part of their plan, which is to deceive innocent people(you are one of them). A good suggestion though, but only for people who are willing to take a big risk. I personally tried playing doublers several times since crytodouble and I must say its worth the risk
Not recommended though.
