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.
In fact, it takes a lot of time to deal with crypto currency. But if you think a little, you can do with minimal investments or do without them at all. If there are many ways to earn start-up capital in the crypto currency, and only then you can go to the stock exchange and work on it.
