People are different and they can have difrerent mindset and investment approaches but in my opinion, if your finance is good enough, and you feel like you already invested enough in Bitcoin, you can stop your accumulation.
am not sure if you really understand what investment is all about, because if you do you won't make this kind of statement above, and the statement is misleading, because you don't have to stop investing all because you feel your finance is good enough, because if investors have this kind of your reasoning, people like Elon musk could have stop investing because their fiance is already good enough, but yet they Keep on investing that's to tell you that investment doesn't have stop, even if your finance is good enough you don't have to stop investing, same applies to bitcoin investment, if you feel that your finance is good enough you don't have to stop accumulating bitcoin, because you are only accumulating bitcoin with your discretionary income and not all your income so there is still need to keep on accumulating.
You can enjoy your money from salary and use it to enjoy your life, increase your life quality and experience while you simply hold your accumulated bitcoins and let your Bitcoin portfolio works for you. I don't see anything is bad if you stop accumulating more bitcoins. It does not mean your belief in Bitcoin broken because of this accumulation pause or entire stop.
nobody is stopping you from enjoying your life nor increase your life quality and experience as a bitcoiner, beside you are only accumulating bitcoin with your discretionary income so keep on accumulating bitcoin with your discretionary using the DCA method or you can be buying on dip, because accumulating bitcoin doesn't stop you from enjoying your life nor increasing your life quality and experience. And secondly bitcoin is digital currency so I don't know why you said that someone should simply hold his or her accumulated bitcoin and let his or her bitcoin portfolio work for them, because the last time I checked bitcoin was and still a digital currency.
At the end people work for money, use money for investment in order to chase wealth and better life quality. They don't invest for example in Bitcoin, to die with bitcoin while their life is lack of things that can make their life comfortable and high quality.
you are miss understand bitcoin investment, and the earlier you start learning to understand bitcoin investment the better for you, and let me say This clear to you if you are investing in bitcoin you are actually chasing wealth and better life, because bitcoin had made a lot of people that invested in it and people that are still investing in bitcoin millionaires and billionaires.
