Yea, the word "satisfy" depends on the individual bitcoin target that he feels is enough for him to acquire based on his own discretionary income in which he is using to buy bitcoin. However, I feel that anyone using DCA strategy to by bitcoin for as low as $10 might not get to the extend that he will say that he has enough Bitcoin until maybe 30yrs-40yrs time.
So considering the word satisfy, it depends on how old that you are and for how long will you continue building your bitcoin portfolio with the amount that you are using to DCA regularly based on your discretionary income. A rich guy who is ready to invest in bitcoin using DCA regularly without missing will have a high chance of reaching his bitcoin target because he has all the resources he needs around him to make it happen fast compare to someone that is an average earner.
A question to ask does someone really feel satisfied while holding Bitcoin? To me I will simply say no because as long as the cash keep flowing you would always want to accumulate enough Bitcoin since bitcoin wallet doesn't have a maximum limit, in as much as your income keep flowing and you apply DCA method then you can never be satisfied even though you have about 10,000 BTC once the income keeps coming you will always apply your DCA money to increase your portfolio.
Most people who had thousands of BTC never stop at one or two they keep increasing their portfolio through DCA except for those people who are on an average job that pays little that could take time to increase their BTC holding in their portfolio.
You seem to be talking about potential personality problems that some people might have in terms of never having enough.
Let's say that you had an income of about $50k in early 2013, and so in the beginning or 2013, you started accumulating around $100 per week of bitcoin, and so you kept your job, and so you don't consider after some point you are going to feel that you have enough BTC? After 9 years you had invested right around $47k and you had accumulated nearly 133 BTC. Wouldn't you start to feel that you have enough BTC at some point? or do you still need more? Even if your income doubled from $50k in 2013 to $100k in 2022, don't you consider at some point you have enough BTC to start to withdraw and maybe you don't need your $100k job if you have enough BTC to provide the same level (or more) income?
