There are ways to calculate out formulas which would show that if a guy sells 50% of his BTC every time the BTC price doubles, then such guy would never experience compounding value in his profits because he would be cashing out all of his profits and merely maintaining his bitcoin investment size at the same amount that he put into it.

A guy who were to cash out 25% of the value every time that the BTC price doubles would be cashing out half of the profits and allowing the other half to compound upon itself.

Surely my choices to cash out up to 10% the value of bitcoin every time it doubled and then later going down to such values of cashing out only 3% every time it doubles, these cashing out amounts are still allowing 80% to 94% of the profits to continue to compound upon itself, and since my bitcoin holdings had gone through more than 8 doublings (see my compounding value discussion) from the time that the BTC price was $250 in 2015, so therefore an overwhelming amount of that value had been allowed to continue to compound upon itself at least 8 times so far, even though some of the amount was withdrawn out of the holdings... which I also claim to be serving as downside insurance, too.
