I am not sure with that but I try to comprehend as well what he said. Whether we sell at a not so high price but we're able to profit from it. It doesn't matter how long someone has to wait for him to buy back.
It's not bad to take profits, actually we have to take profits whenever we can because that's the goal of everyone why we invest.
taking profit from your investment is not bad but still depends on the quantity of bitcoin you have accumulated. So in a scenario whereby a newbie started his journey of accumulating bitcoin, and he or she haven't gotten to anywhere with Their accumulation (have low quantity in their portfolio) and started taking profit from their investment expecially for those who are planning for long-term holding .
They doing so in taking profit from their investment in any increase in price of bitcoin. Shows that they lack principles in their investment, because that action may only result to slow growth of their portfolio. But as some one who have gotten far with us accummulation like holding from 4-5 yrs and above can start taken profit from their investment not those that just started their accumulation journey.
Taking profit from your investment is good, and actually suggested so you can re-invest those profits into another asset. BUT in a new asset class such Bitcoin, I would discourage anyone from taking profit in any price under six digits. Why? Because we haven't truly seen its real value financially, and its REAL value socially and politically.
