According to Michael Saylor, founder of Strategy (formerly MicroStrategy), in an interview with Wu Shuo, he does not hold any other cryptocurrencies except bitcoin. About four years ago, he publicly disclosed that he held 17,732 bitcoins. At that time, the purchase price was slightly less than $10,000 each. This information can be found in my public tweets. Since then, he has bought some more but never sold. So there are more bitcoins held now than at that time, but the specific increase is not publicly disclosed.
