any investor who starts his accumulation during the bull season should know that the best time to pull out will be for the second bull season after checkmating how far he has gone through investing and if it's worth it.
It is wrong to advise new investors to focus on 4 years bitcoin accumulation time frame and sell after four years, because I think it seems like it is not worth it selling your bitcoin at you took your time to build and gow gradually for four years and you sell it for little profits to hold fiat. What is what doing, is worth doing well. Therefore a new young investor who just started his bitcoin journey should have a long term with a committed mindset for two circles and above or minimum 10 years and above, because bitcoin should be treated as an investment that we should hodli till old age, so that we ca use it as our retirement funds.
There is what is called the compounding effect of bitcoin overtime, if you sell after four years, you will miss that compounding effect of bitcoin, because there is a stage that your bitcoin size will reach that even if you don't buy again and you didn't sell but just hodli, your bitcoin portfolio will still continue generating more profits for you that you cannot imagine because of the large size of bitcoin that you have. Don't make the sacrifice and commitment that you have used to accumulate your bitcoin for four years be a waste of time after you have sold it because if you plan to buy back, you will be a loser since you will not be able to buy back at those cheap price that you bought them. Imagine someone that bought bitcoin at the bottom line of the bear in 2022 for 16k should sell all the bitcoin he accumulate by next year bull run, do you think that bitcoin will fall that low to 16k in the next bear market after the bull run.
There could be some other reasons why some people might decide to sell all or part of their bitcoin investment after holding for a full circle. It could be on the ground of health issues or old age. This is what makes some people have a shorter holding period. You never can tell the prevailing circumstances that prompted them to sell. But if an investor doesn't fall in this category of health issues or old age, decides to sell his bitcoin after 4 years, they can sell part of their bitcoin rather than selling all of it. It could be that they had projected that they will use part of the profit gotten from their investment after 4 years, for carrying outs certain projects. So at the end of the 4 years holding period, they can sell part of their holding and use the profit generated for their projects. What is wrong is selling all of accumulated bitcoin.
