I wouldn't even want to imagine the state of the markets if bitcoin goes low enough where Strategy finds itself forced to sell some of its holdings.
I find it strange that you say that because if I remember correctly you have followed, at least sometimes, fillippone's thread on Strategy. Most bitcoins Strategy has bought since half a year ago have been bought via ATM, basically printing money to buy bitcoin, or if you prefer more specifically creating more shares to buy bitcoin. This is not debt and this move is contrary to what is usually a share capital increase in companies that follow a fiat standard, almost all, because in these a share capital increase is dilutive while buying bitcoin with the money collected from the ATM Strategy's move is accreative. XXI Capital is going to copy him in this.
Strategy's debt is convertible debt, which means that in the normal scenario it will be repaid by converting it into shares at a certain price. If you go to
https://www.strategy.com/debt you will see that the share price has already exceeded the convertibility price today. In addition, the first is due in 2028 and is strategically planned in terms of maturities.
Anyway, I don't want to get long, but to summarize, yes, there is a possible scenario in which Strategy would have to sell bitcoin but it is so bearish that none of us on the forum would consider it.
