Exactly. If your finances improve and you have more cashflow, you can increase the purchases on the way. People tend to have terrible advice for normal people, in the altcoin world it is even worse as they want people to spend time daily in crypto farming, chasing events and drops, keeping up with news and chats and so on.
Bitcoin should be as neutrally minimalistic and as easy to use as possible. Normal people should not need to check things daily for information, it is too time consuming and manipulative to live like that. It should become second nature, that is what makes DCA perfect.
What makes DCA even more perfect is when we can implement it without stopping and always adjust it to our own cash flow each month. This means that our own level of consistency with this method must also not decline if the goal is to increase our Bitcoin by repeatedly buying it whenever we have cash. But beyond that, I don't think anyone who spends time exploring available information by reading more isn't doing anything wrong, as that's how everyone gathers important information while accumulating Bitcoin after they learn more about it.
Other things like altcoins, events, and drops are commonplace and may not be considered important by everyone, but that doesn't mean they're wrong to know. Having more knowledge about many things will certainly be very useful, at least in preventing us from going down the wrong path when we want to invest in a proven future asset like Bitcoin.
