You seem to be mixing things up a little. I don't know how you came to the conclusion that DCA require large capital but the much I know is that the main ingredient of the DCA method is the sequence of buy that will not have much effect on the finances of whoever that is using it. So, I see the DCA approach as the opportunity people with small capital have to build their Bitcoin portfolio because it enable them to buy small amount per time and also regularly.
Many people following this discussion are applying the DCA method with as little as $20 per week and doing this for a year will amount to something very big. The first consideration for those who want to start the DCA method is to calculate what percentage of their capital they can invest in Bitcoin that will not become a burden to them and make them worried when price drops or want to sell so quickly. So, both small and large capital can apply the DCA method.
I even noticed that those with big capital will love to just buy at any price they consider good for them and not just follow the DCA that makes them wait to buy weekly or monthly as the case may be. Check all the whales entering the market, they just buy when they want to and do not follow any schedule.
I think it's like this if someone with small capital and also someone with large capital can both practice DCA as a way of investing in Bitcoin. For example, like Saylor, he accumulated a large amount of Bitcoin in one purchase and it was all because he had large finances and He also did it with DCA. So, the DCA strategy does not look at a person budget to apply it in their investment planning. Whether we make $10 per purchase it won't be a problem because we buy it regularly and we are targeting investment planning for a period of 30 years or for assets in our old age.
That way, adjust the budget as best as possible so that we can do it regularly so that we can accumulate large amounts of BTC in our portfolio someday. Bitcoin is getting more limited from year to year until it eventually runs out in the mines and scarcity will occur at some point in the future. And when purchases increase, stocks thin because people will hold them for a long period of time for their retirement assets, then prices will rise unexpectedly. So that's where we will see the door to our success in the decades to come. Everything requires a process like what investors did in 2013 where they invested by accumulating at low prices and being able to hold it until reaching a new ATH and a new ATH in their investment period.
