I have booked profit from when it was 400$ but i know people that have made profit from when it was 20$ each!
We missed the golden age where it was easy to make tons of money if you invested some money into bitcoin sadly enough.
The golden age was before 2013. But during that time, the bitcoin was in early stages. There were more risky.
The price of bitcoin was very low then. But there was little possibility that will succeed. You had to take a big risk to invest.
