Your explanation certainly makes sense because applying the DCA strategy of course you don't have to be skilled at reading charts because you make purchases at every stage when you start. DCA is the most admired strategy for those making long-term investments, either for the next 10 years or 20 years. But basically when there is a question from someone from your relative why you buy at a high price when you can wait to buy at a low price (well in this perception you can give an answer if I will calculate the average purchase entry when I reach the peak to exit at in the next 10 years) it will make them amazed by your answer.
Well, at the level of adjusting the emergency fund, this is not very important for some people because if they get a weekly income they will adjust the percentage level they will use in Bitcoin investment, even so it will be in line with their concept without any obstacles that can hinder them. On the other hand, if your income does not determine where you pursue odd jobs (sometimes you work or not) of course the level of adjustment for emergency funds is quite necessary so that you don't miss a purchase step. Well, emergency funds are of course prioritized to cover gaps when you don't get income at that time, so you can use emergency funds at that time. Isn't it like that?
Emergency funds for some of them are not to be taken to invest, but rather emergency funds for their living needs when they are pressed by a disaster that occurs, be it a flood, earthquake or the death of a relative. So they can use the emergency funds for that, instead of selling assets/bitcoins they own. In fact, what you explained is not wrong, but the term might be better used as cushion funds or reserve assets that they can take so they don't miss the stage of their purchase.
After everything has been successfully adjusted to good planning, of course long-term investments can run according to their plans because they have managed their financial levels without disrupting the course of their investments. We have even heard that they often sell their BTC holdings due to pressure from the situation they are experiencing, so this is where emergency funding arises that must be considered.
