Yes. Investing is one way to earn more bitcoin especially in the long run, which later turn into a big amount of money if converted. But not in every investment you do, you'll win. There's also a time for losing. Always remember that only invest an amount that you can afford to lose. You can invest in bitcoin but make sure that you have enough skills and knowledge in bitcoin, about investing, and how it works because you might only lose what you've invested if you don't have these. Timing is also what you need, and invest at the right people.
