Doing it long-term way is the wisest thing to do.
You will cherish every moment of it once a person understands why he hodls and what will be by the end of such a journey.
Nobody knows or can know what would become of Bitcoin or his investment on the long-run, we're only optimistic that Bitcoin continues to perform well and appreciate in price and increase the value of our investment. Yes the person can continue to understand why he holds of which apart from securing his financial future, people might have other reasons for building up their Bitcoin portfolio and holding for long.
However, one can decide to take some portions of their profits only if they invested for very long like about 4-10 years, it would be very foolish for one to sell every Bitcoin in their wallet just because they've invested for a longer period they can choose to sell some portions and channel into other business areas and generate more income to keep adding Bitcoin to their portfolio but taking profits should strictly be when they've invested for a very longer period and not below the full circle.
Everybody is at liberty to do whatever they wish at the end of their holding period. For example: A person who invested into Bitcoin throughout his working years and held for 30 years is already a long-term holder and he can decide not to deal with the volatility of Bitcoin at his old age and sell of his investment to take care of his much older years.
Again people hold for various reasons, a person can be investing into Bitcoin for the purpose of starting a very profitable business venture at a much later time, and after like 10 - 20 years of investing and reaching his accumulation target, isn't it wise he achieved his dream? Perhaps he may wish to his sell off and achieve his dream and resume investing from the proceeds of his business.
Some other guy might wish to keep holding and only shave off profits in bits to take care of himself at the expiration of his holding period.
All these scenarios are valid, everyone is at liberty to do whatever they want with their Bitcoin at the end of their holding period, although I'm likely going to be the third guy, but It's entirely my decision.
Yea, you are actually right bro, we are all grown adult, and as such we are entitled to do what ever serves our best interest, the only problem I have with most newbies investors or those investors with trading mindset is that they tend to sell prematurely or they sell during their accumulation stage when it's no where near something that can change or impact their financial status forever, that's what I actually hate the most, regardless of anything, as long as you are a long term investor, it doesn't seat right when someone that should be thinking on how to accumulate more Bitcoin, be selling off for minimal gains even when he or she is still in his accumulation stage, that's very myopic and unreasonable.
Then another thing I hate to see is either a newbie investors or a veteran selling off his or her holdings just to end up buying alt or meme coin just because of greed for 10x to 100x, to me it's the most stupid decision making an individual will ever do to him or herself, because at the end it wouldn't ends well as he or she expected, because alt and meme coin will always behaves as one, they falls more than they rise, which is a trait no reasonable individual will know and still invest heavily, unless that person just want to gamble.
