from 150k btc to 11 million pieces, that's still very far away why do you say that Saylor has half of the supply, I think other large companies or other retailers will not remain silent seeing this they will also join in and the more people who hold BTC then prices will be difficult to control because no one holds supplies in large quantities.
Checking the Bitcoin price is not that easy. Therefore, I think we should not be too afraid of this situation. In the past, people would get scared and sell their Bitcoins when a negative tweet was made about Bitcoin, but now it takes bigger events to affect the Bitcoin price. One company or one tweet cannot easily influence the price of Bitcoin.
The number of investors is increasing day by day and the expectation that the Bitcoin price will increase is also increasing. I know that people or companies purchasing Bitcoin at these levels will make a profit, and the investment they make during this period will return to them as a reward.
