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.
If the goal is to have long-term business innovation in bitcoin, whether it be a product or service, then the main requirement in utilizing their bitcoin is that they must continue to hold it, and that becomes their main obligation.
By owning bitcoin, they gain strong public trust to start a business, but the further away the type of business is, the more questions there will be about its management.
Or will they simply be strong long-term Bitcoin holders? In my opinion, I think they will sell it, even though we don't know that for sure, but not their entire holdings. Perhaps only a small portion of their holdings will be sold over the next two or three decades.
Rationality is also needed to look at this in terms of the probability of actions that will be taken.
I agree with your comment. As you said selling some part of the holding. Selling a person's holding until the end of his term will never be the right method or the right decision for his investment. As @jj says about gaining some part of the investment. When your investment earns 2 times the amount of your invested money, then you can withdraw some amount and enjoy the profit. If you want to enjoy by selling some amount of holding or investment before the end of your investment term, then you can adopt this method. It will never be the right decision for a person to sell the entire amount of holding. Even if a person's term ends, it will not be the right decision to sell his entire holding. It is okay to withdraw the amount he needs but it is never right to withdraw the entire holding.
