That might not actually be true, because there are many people who don't buy with DCA, yet they have enough knowledge about the future of bitcoin. Because according to your assumption, you are trying to say they people who buy with other methods don't understand the potential of bitcoin. DCA method has nothing to do with understanding the potential of bitcoin. Because even newbies who were influence by others to invest in bitcoin do buy bitcoin with DCA method. Even though they don't really know or have enough knowledge about the true potentials of bitcoin at that initial stage. DCA, just like every other methods is applicable by all sets of investors, both those that understands the potentials of bitcoin and those that don't, but they just have to invest because they see others investing in it. While some where influenced by others either at home or in the office.
Basically DCA is just an investment strategy, while this strategy will most likely not have a big impact on your optimism about the future of bitcoin. There are many investors who are optimistic about the future of bitcoin, but they have different strategies, not just DCA. For me, that's not a problem, the most important thing is that they try to make Bitcoin an investment, whatever strategy they use.
DCA is very useful for those of you who want to take advantage of price volatility to carry out accumulation. Even though you can buy all at once at a certain price, DCA can be considered as a backup strategy if the price falls further than the previous purchase. If you don't set aside a budget, then perhaps you are ignoring the opportunity.
