Bitcoin is a kind of investment. You invest money, and of course, you loss money as well. I mean not all the time you are able to earn, there are times that you lose also. My highest bitcoin earning is ..5. It's quite big because I invest my money and my time as well.
I agree with this, bitcoin is a great investment that will help us to become rich, we just need to invest some money, more time and a lot of patience here, because this is not a straight road you will experience heartbreaks and downfall but stay on the line and im sure you will arrive.
