Michael Saylor is a Giga Chad, he won't sell for profit. I believe he's in a long term journey with those who truly understand that the world needs something like Bitcoin to exist. - A fall-back/back-up for the current financial system just in case it collapses.
Why not? The profits it gets benefits the company and everything to its future investment plans. Also, it's a company owned by multiple people who have shares and doesn't have 1 person to do the decision making. I know how bullish to bitcoin Saylor is, but a company/incorporated such as microstrategy doesn't work like that.
Because Bitcoin is like any other sound investment/asset, like long term value-stocks with good fundamentals, and a long term store of value like Gold. Zoom out both the Dow Jones and Gold to the maximum to give yourself an example.
It's also more valuable for the company to keep on HODLing because it itself makes the company more valuable. If the company needs fiat or wants to hold fiat as hedge, they borrow against the asset, not sell.
Plus if there is going to be some selling, there's also going to be some buying. It's not going to be just "for profit". They don't play pleb-games like us.
