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.
I believe that no one should ever be satisfied with making money, when you're stagnant and always receiving debit alerts without credits, it hurts your finance gradually until its obvious that your finances are diminishing. Investments are what needs to be made on a regular to keep your residual income pumping in and increases the security of your finances.
In bitcoin accumulation journey, the most important thing is to start up. Starting with $10 monthly isn't a bad thing at all, if that's his spare funds, its welcome. Remember you invest with your spare funds and not emergency funds. One good thing is the desire to invest. Once there is desire, there possibility of a good result is high. The person that started with $10 monthly and has a target can increase his investment capacity with time as his finances improves.
