Based on your question, I know that MicroStrategy, Galaxy Digital Holdings, Marathon Digital Holdings, Tesla, and Coinbase Global are some of the of the top investors in Bitcoin, and they hold a great deal of it.

Except for Microstrategy, all these other companies are real dwarfs with their investments considering how much they are actually worth. It seems to me that some of these companies are buying Bitcoin just to draw a little more attention to themselves, but they are far from serious investors.
There is no doubt in what you have said, because if those other companies are serious about buying Bitcoin consistently with their strategy, they definitely will be very popular, like Micro Strategy, Black Rock, and Tesla.
It is only when someone carries out a random search about a big investor in Bitcoin that they can come across the names of several Bitcoin investors, while an average Bitcoiner would first mention Micro Strategy as the big investor in Bitcoin because of how popular the name has become and how consistent they are in steadily buying Bitcoin.
