I get your point, but I don’t fully agree. Overaccumulation isn’t really a fixed stage, because everyone’s financial situation and risk tolerance are different.
You're right when you said that overaccumulation is not fixed, for me I think overaccumulation is when you get to a point where you feel that the amount of bitcoin you have accumulated is More than enough for you but not just after making the purchase for few months and start claiming that you have reach the status of overaccumulation rather the accumulation journey need to last for like 4-5 years or more. this way, we can be easily convinced that a guy have stack enough bitcoin in his portfolio . Because we can't possibly say that owning 1 bitcoin is what qualifies you when we know that the value is not always stable, the more you're targeting to reach 1btc that's the More the price will keep moving.
Moreover our investing capacity differs.Some people might take profit earlier without it meaning they’re traders, it could just be part of their personal strategy.
Taking a profit when you have not reach your investment goal does not make you an investor especially during the early stage of your accumulation journey, if you start selling early it means that you're not into Long term investment maybe you have not yet figured out the difference between a trader and investor. As an investor you're supposed to maintain the ongoing buying of bitcoin for like 4-5 years or more that's Depending on your weekly or monthly bitcoin purchase but Investing for like 7 to 8 months or 1 year and start attempting to sell seems like a play and not a strategy.
