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 invest in Bitcoin since bitcoin wallet doesn't have a 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.
