Taking profits like you said is dependent on many factor and
Taking profit from your bitcoin investment is bad. It is the same thing as gambling because if you sell your bitcoin at a high price, you will need to wait for the bitcoin price to drop to a certain price before you can buy it back. But if the bitcoin price keeps going high, FOMO can make you lump sum on bitcoin so that you will not miss out or you end up losing hope of buying back because the bitcoin price is too high.
I don't understand what you mean that taking profits from your Bitcoin investment is bad neither do I understand how that is related to gambling. Are you suggesting that one should never sell Bitcoin? Why do I sense insincerity in your statement? Does it mean you don't plan to sell some of your Bitcoin at some point in the future?
I've tried to understand what he's said. And I think he's pointing about selling at high price and never able to buy back at a low price.
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.
