It makes sense to buy every day this is also a DCA strategy just like what El Salvador did this is also to reduce the risk of price fluctuations but for me personally or people who earn monthly or weekly buying every day will not be able to, I think whether daily weekly or monthly is the same the most important thing is to consistently accumulate because that is the main key if you want to get significant profits from bitcoin.
Indeed, people are busy arguing about which strategy is best but forget that the goal of DCA is to accumulate as many bitcoins as possible. Whereas daily, weekly or monthly DCA is almost the same and the only difference is the time. Therefore, we should rely on our financial situation and choose the most suitable strategy. We can't say that daily DCA is worse just because it doesn't fit our finances.
Remember that the goal is to accumulate the most BTC, so in addition to choosing the right strategy, we can also change flexibly depending on the situation and time. We don't have to be so rigid.
