If our investment doubles before our time limit ends, we can withdraw some money from our investment and enjoy it. But even if our time limit ends, selling our entire holdings would not be the right decision. Because I think the price of Bitcoin is still in its infancy. The price of Bitcoin can increase a lot in the future. So if you sell your entire holdings because your time limit has expired, you may regret it later. So it would be best to withdraw the amount you need and keep the rest of the holdings.
I think every withdrawal should be planned and not just done because of an increase in the value of your stash, that's basically the technique of a trader selling because his investments has yielded profit over a short period of time and not the strategy of an investor, the point of investing is to make profit but this profit should not drive your into selling early, an investor should be disciplined in his investments, if you can sell because of a quick profit then you can also definitely sell because of a quick lose, so even though you are making profit, you shouldn't sell until the investment timeline has ended and you should know how much of your profits percentage you sell each time you sell.
It's all about the planning or targets that we make at the beginning before investing. There's nothing wrong with it if our targets have been achieved then we make withdrawals at a faster time, but I think there are many changes that we can make to take bigger profits in the future so that the investments we make can be bigger and it will be more profitable not only fixated on the small targets that we have planned, in fact I think if the investment target has been achieved it's better to let it grow even more and we can do the same thing with new targets again.
