Your luck is still good, I bought 50 BTC in 2013 and then sold it in 2015. If I could predict and be patient until 2021 then I would be rich. Sad and happy is actually a thin difference. Keep spirit to be the number one rich person in your city.
Every trader has the same goal when investing in cryptocurrency, Buy when price are low and sell when price is high.
But until now no one has been able to accurately predict the price of cryptocurrency, and it is even more difficult to provide long-term forecast. Every trader will regret knowing that the price of coin has increased dramatically after they made a sale, but if they think more realistically, actually they have made the right decision, because they have got the advantage.
Whatever happened in the past, you can never do again in the present, because you have to spend $62,155 to get 1 Bitcoin.
