4-5 years or even 10 years in my opinion is the time limit that allows an investor to profit from Bitcoin investment and we must admit this, it's just that the profits obtained are not as satisfying as long-term profits without a certain time limit that will guarantee you will get much greater profits from all that.
Real evidence of the Bitcoin price trail at that time when compared to now has reached 1 and a half decades, the price continues to increase and passes 4-5 and 10 years the price continues to increase. So there is a possibility that such a case will happen again that the price of Bitcoin the longer you hold your assets firmly, the price will continue to increase which will provide much greater profits compared to the profits obtained under 10 years.
And this is often discussed and always in every comment that having discretionary income is a safe way in the investment journey, because discretionary income is the income that remains after paying important costs and basic needs and so on to be used to buy Bitcoin regularly which will not cause problems in your life journey and also your investment. And emergency funds are also needed because we don't know what will happen to us in our life journey, especially in financial matters and when we really need it without involving Bitcoin at all.
It seems pretty short-sighted to me, if a guy spends 4-10 years to invest into bitcoin and then he sells all of his bitcoin. There is no reason to conclude that selling all of your bitcoin is a good plan, especially if it may have had taken 4-10 years or even longer to build it up. Some kind of
sustainable withdrawal whether price based and/or time based seems more practical rather than selling all of the BTC that had been accumulated.
I think people are mistaken that range you recommended for the right time to sell even when it should be a range should expect to see significant growth in their Bitcoin value and not necessarily a time to sell, this being how I understood it. Most people buy Bitcoin today and next day they want to see it double or let's say rise significantly but when that does not happen, they feel bad and sometimes are prompted to sell and leave especially when they put money they cannot leave in Bitcoin for a long period of time. However, if such person can hold for at least 4-10 years, then the chances that they would have seen their Bitcoin appreciate so much, base one what we have seen about the market cycle occasioned by Bitcoin halving of 4 years. The 10 years in the range covers two cycles and the more the number of cycles an investor holds, the higher the chances of seeing significant growth in the investment. I think this is my understanding of the 4-10 years suggestion. If I missed something or made a mistake, kindly correct me.
