Selling our Bitcoin before overaccumulation means that it is a short term plan, which is not very good for our Bitcoin investment, and its likewise a trading mindset, I have been trying to stack up my bitcoin for quite a some years now, its best for me to focus on my long term investment and get to my overaccumulation before i can make use of lower amount of Withdrawal. But right now I am more interested in growing my Bitcoin, That is why it is important to have a strategy set aside that would not force us to sell before Overaccumulation. That is why it is important to have our emergency funds set aside and floating funds as well.
I disagree with you, selling ones investment before over accumulation stage doesn't actually mean someone is a short term investor because it is possible that one can be accumulating and holding for up to 4 years or more without getting to there over accumulation stage but yet there investment can still be okay if they wants to sell and of course accumulating and holding for 4 years is already a long term so selling at this stage doesn't make one a short term investor and you should also know that over accumulation is not something one can get so easily because sometimes an investor can spend more than 6 years before they will even get to an overaccumulation stage so don't get it twisted.
