By next year, bitcoin should get to its ATH, and probably many people will be selling their bitcoin at a high price. And some will sell at 10-20% profits you mentioned.
There's a chance that Bitcoin might make another ATH this year and then cross that one once again next year. However, if someone knows my strategy then it can be executed this year or maybe in next year as well. It can be useful for those investors as well who buy Bitcoin when market faces huge dips.
So, a good investor learns how to sell at the top, then wait patiently for the rally to end, he or she can then buy back the same amount of bitcoin he or she previously had, then use the profit left to either invest in other assets, or withdraw it and use the money to solve some of his or her real life problems.
I highly agree with you and I believe we both think similarly. Whatever you said is quite true about a good investor, the market always goes up and after a big ride it has to go down once again as the buying pressure reduces and selling pressure increases.
Let's look at the current situation of the market where many people are creating fud that bull run is over and we may not see a new ATH and that's causing fear in the brains of the weak hands who are selling their Bitcoin holdings because of that fear and because of those people it's getting dumped day by day.
Now those who are good investors often wait for such selling pressure and but when they see huge dumps and then continue buying when they see more intensity in such dumps. After sometime when huge investment companies start accumulating Bitcoin publicly then the buying pressure increases and bad investors keep buying when prices goes 10% up or more and good investors at that point can sell with profits and wait patiently for months to see similar market conditions.
