Talking about selling is more of a trading and can lead people to wrong direction, the longer you keep accumulating the more profit you get , so selling shouldn’t be your major concern
Yeah everyone has a need at every given time that is why it’s alway advisable to have a reserve fund or emergency fund , it helps you sort out urgent needs with that selling your Bitcoin won’t be necessary and can be kept for a longer time with a good profit overly .
Selling an investment is definitely not a good move. But there is nothing wrong with taking profit or selling part of it after achieving the goal and taking necessary steps. Talking about selling is not like trading, if you can't do any work or any necessary steps or necessary needs with that investment, then why would you invest so hard? But it is true that selling the entire investment will never be the right thing to do and it will be foolish.
Even before achieving the goal, an investor should not plan to sell the investment. The investment fund is your asset, our main objective is that you can use that asset properly and use it in the best possible way. In this case, my advice would be that you should not plan to sell the investment before achieving the goal or in the initial stage of the investment, or selling the entire investment even after achieving the goal is not the right thing to do. However, you can certainly sell the partial investment after achieving the goal and take the necessary needs or necessary steps without hesitation.
