They not only mortgaged Bitcoin but also mortgaged their company's stock. In short, they used all means to buy Bitcoin.

$BTC You say that MicroStrategy is spot and won't explode. I just laughed. First, it is the company's debt, and secondly, it is a cycle of collateral. To put it simply, it's low-priced spot with high leverage. Once the stock price or cryptocurrency price reaches a specified position, you will know whether it will explode or not. I think 70,000 is definitely a test for them. If 70,000 is fine, 60,000 will definitely go bankrupt. This is not alarmist.
