I can't imagine Saylor's ambition to become the world's largest BTC holder. He's on track to reach 1 million BTC, and I'm sure he has many ways to secure new capital injections.
Let's clarify this because of the novice.
Michael Saylor is a person, and MicroStrategy is a company. Saylor owns roughly 17,732 BTC as of today, while MicroStrategy, the company he's the executive chairman of, has bought over 600,000 BTC. Meaning that it's MicroStrategy that has over 600,000 BTC to its name, and of course, it is owned by many investors.
Yes, you're right, but Microstrategy is his company. He's the CEO, and although he's stepped down as CEO, he's the one who takes the lead in decision-making. He even made the decision when he shifted the company to invest in Bitcoin. But I forgot to save that article.
Saylor's reputation changed people's perceptions. He captured the public's attention with his decision to buy a large amount of Bitcoin. Although it wasn't his, but belonged to investors, he managed it well with his strategy. He managed investor money with capital from the stock sales he'd made. This means he took good care of his company, and the profits they generated were substantial, convincing many investors to trust him and Microstrategy.
He does not own all of it and he's major stock holder that's why he has major strategic control towards decision making about on where their company heading.
Their major shift on Bitcoin is truly amazing since with this they gain a lot of profit compare on their old model.
