It's better that we don't use timeline as the main focus on our bitcoin accumulation journey because it will depreive us from accumulating as many bitcoin as possible overtime. Instead, you should have a bitcoin target which you will plan to accumulate so that you can focus on that quantity till you achieve it irrespective of the time duration that you will use to accumulate it. S that, you can know when you are entering an over accumulation phase.
Profits shouldn't be the main thinking when accumulating but reaching your bitcoin target should be your priority.
No, I think that it's more better to accumulate Bitcoin with a duration of time than setting a Bitcoin target, because if you set up a Bitcoin target, you are limiting yourself, you might stop accumulating if you get to that target very early, but if you set a duration of time like 10 years or more, you are definitely going to accumulate more Bitcoin as long as you are consistent in your Bitcoin accumulation journey, because I know that their are times you might even invest aggressively or sometime buy during a dip, so accumulating according to timeframe is the best way to accumulate a bigger stash of bitcoin than setting a target that can be easily achieved.
In fact, the way to invest in Bitcoin is entirely up to the individual who invests in Bitcoin. How long a person will invest or after collecting how much Bitcoin he will stop investing and lead a life through sustainable withdrawal depends on the age of the investor, his income and his plan. However, the target should be to earn that amount of Bitcoin, by winning, a strong security is created for the future life. Now let's say if someone is 50 to 60 years old, then it will not be good for him to invest in Bitcoin for more than 15 to 20 years. So he should invest a little more aggressively in 4 to 10 years because he needs to invest quickly and get financial prosperity quickly if he reaches the stage of over accumulation. But if one who is 25 to 35 years old, he can continue to invest for a long time. Even if he can do DCA at low amount, then there will be no problem because he has enough time . However, what is most needed here is to have enough money. There must be discretionary income. The more discretionary income there is, the sooner it is possible to reach the over accumulation stage. So it is clear that the same strategy does not work for everyone because some people have time but the amount of money is less, so the target depends on the situation. However, the intention should be to go to the over accumulation stage. And after someone reaches this stage, if they want, they can spend their life in sustainable withdrawal without working anymore or if they want to pass the time, they can just do something for a couple of days a week or a few hours a day, it is up to them.
Age and time has nothing to do with and can't be a limitation for anyone to invest in bitcoin.
As an old man of 60 years and above and you are investing does not mean that you have a little time frame to invest, what if he lives longer than that young person you feels have more time to live an do not die as you expected, and even if he has a short time to live he can pass on his inheritance to his children or grand children or to someone he love that he would be pleased with, age is not a guarantee to having a successful and booming bitcoin investment, since it does not have limitations or barriers.
In a much as the old man can accumulate and hold for long term without tempering, using his discretionary income like a younger person he his free to do that, we all don't know how long we will live on earth, as long as you are alive keep accumulating and holding for long term.
