There's a lot of hackers out there make sure you invest money into right place. There's no easy way to get back  your bitcoin with profit of course you really need to wait and have faith that you will earn profit.

But for me i just invest my money and turn it into bitcoin and store it in a paper wallet, and i will gonna wait for at least 6 months to 1 year before withdrawing it. The best thing about this method is that you will hold your bitcoin and no one's going to rob it and you will just wait for a long time before earning a lot (The longer you withdraw it, the higher your profit will be)
