Someone did a video of the math behind Microstrategy's leverage.

What are you guys thoughts on this? What I dont get is will they ever NEED to sell? Are are they absolutely covered by holding Bitcoin (which should guarantee the value of the company)? I dont see a scenario where MSTR will be forced to sell from this information. This whole thing does scare me so I would like to hear your thoughts on this and if you think this might have a detrimental effect on the crypto community if MSTR ever unravels.
