These are great point. I haven't thought of it as a PR move or something that would benefit the company. I can see this helping the company. It seemed like Saylor wasn't interested in running the company anymore.
Saylor and Musk are good at spreading the word on social media. This and amount of money they invested definitely contributed in bringing bitcoin to its all time high prices. But don't you think there are many more saylors and musks who don't advertise their investments but are heavily invested in bitcoin and crypto?
So far bitcoin was always able to reach its previous all time high and make new highs. Why wouldn't it repeat the same thing again?
