However, what we don't know is when they will sell, both Saylor and Thiel, because for a company to be profitable, there needs to be recorded profits, so it's certain that they won't hold on to all their Bitcoin until they die. They will definitely sell, but we won't know when that will be.
Now this is the thing. Strategy is built to rely on Bitcoin and be a treasury company which shouldn't sell
Cause if they do, it means they plan on going out of business because it's going to affect investors confidence
They would gain more from just holding and accumulating for now. Maybe in the future they may choose to use the coins for other service rather than service
Maybe a lending service with interest. Anything can happen but for now they are and need to keep holding.
