One of the best feelings as a crypto lover and holder is to see your holdings rise and increase in price while your portfolio is swelling up. But majority of people are carried away with the joy and gladness of this market pumps and then keep waiting to take profit at the peak till it begins to dip and they sell way lower than what they should have gained. It's something that's common to almost all traders. I can say greed is part of it. How do you think this problem can be solved.?
It can't be solved!
Greed is something intrinsic to human nature, and it is extremely difficult, yet not impossible to control. Once some sort of control is possible, then a remedy for trying to sell at the right times to maximize profit is unfortunately experience.
With experience, and after getting burnt several times your risk-adversity changes, and only then you're able to start devising a strategy that works for you. Like as soon as you're taking 20% profit of your investment you'll be happy or something similar.
