Selling an investment will never be the right decision and selling an investment before the expiry of the period will not be the right method of selling an investment. In many cases, we can call someone who has been investing for 4 to 5 years a new investor. You should never think of selling your holding or investment until your period expires. You should always continue to buy until you accumulate enough Bitcoin in your portfolio. When you accumulate enough Bitcoin in your portfolio, you will wait until your period expires. After the period expires, you can do whatever you want with your holding. But I want to say that if you have not planned anything with your holding before. For example, many people think that with the money I get from here, I will start a business or buy a car, etc. Instead of doing this, it would be better to withdraw all your money or investment from Bitcoin, withdraw what you need and leave the rest in Bitcoin.
I would not call it the right move to randomly sell the investment after achieving the investment goal. Yes, you can make a profit from the investment after achieving the goal, but selling the whole thing is not advisable and it would be wrong. After achieving the goal, you can diversify your investment by selling the partial profit or you can create a place-based business or you can create a company. You can even enjoy selling the partial profit. But selling the whole thing would be a foolish act and you might tell your grandchildren the story of that foolishness with regret.
