While you might be right about some investors monitoring the price movement of Bitcoin and the possibility of it influencing them to sell when they see price going down or consolidating. You can't also take away the fact that some are doing that in order to learn the daily, weekly and monthly charts or movement of Bitcoin. Lots of people do this to be able to make their weekly contents for their audience who follows them on social media.
I don't think it's wrong if content creators take advantage of this moment to present data and information about daily, weekly and monthly movements and, if necessary, correlate it with the investment model with DCA. It's just that we take the positive points if they contain what was conveyed by the content creator, just use them if not, just ignore them. I think it's safe.
