I think the most important thing for everyone to do is to keep their emotions as usual. At that time, many people often feel nervous about why they make many wrong decisions and lose a lot of money. Most of the time when dumps start to panic and start selling far below the button and unable to return before another surge, we must hold our coins or make long-term investments, to get higher profits and prevent losses.
This is the most important thing. Controlled Emotions will never let you making wrong decisions. Wrong decisions will take you in debts. I mean that when you decide to sell your coins and the price is quite low you will definitely lose your money, but if you remain silent and patient, you will never lose your money and with the passage of time you will become successful.
