In order to benefit from crypto currency investment, you need a lot of money. Think about something like $1K or 2K. You might gain by investing $10, but that will give you a small profit and it is not worth your attention. Secondly, you need patience. The price fluctuates and can go very deep down, but if you can wait for it to regain and then only you will be successful, even if that means waiting for 5-6 years.
