My main concern with MicroStrategy's regularly massive Bitcoin accumulation is what happens when they eventually liquidate their holdings into fiat. No matter how bullish Saylor may be, his investors will not always share the same stance. At some point, they will want to secure profits, which could lead to significant selling pressure on Bitcoin. Such a move could heavily impact the price and resemble monopolistic behavior or even market manipulation.
Not only is Michael Saylor buying Bitcoin, but various holders including Michael Saylor and many other treasury companies have taken each Bitcoin as a strategic reserve. Now almost many countries have Bitcoin strategic reserves, if Michael Saylor wants to sell, it can certainly have some impact on the market. But the dip in Bitcoin price that will be created in the market due to Michael Saylor's Bitcoin sale will be used by many investors.
As a result, the price of Bitcoin will not be different from the sky to the ground, but naturally if there is some dumping, it will be different countries and different people holding, and the market will return to the east. However, there is no doubt that weak Bitcoin holders may panic.
