...but the only thing that worries me is that these heavy investors are here to make the profits and they will dump everything whenever they think that they made their profit and it comes affect the market big time in the form of major correction.
It’s something that’s an option, because it’s all about how to make as much money as possible. However, when it comes to these large companies that invest in BTC, many analysts agree that they will not sell their BTC so soon and that they have invested in the long run. If we take the already well-known MicroStrategy as an example, then their initial investment has almost doubled, and instead of selling, they are investing again $400 million in Bitcoin these days.
Another important thing is that all of them, as far as I know, invest through OTC, which allows them not to influence the price too much - because it is in their interest to buy as much as possible at the lowest possible price. In the case of the sale, I think they will go in the same direction again, which means OTC and minimal impact on the crypto market - although they will not be able to hide from the public that they are selling BTC - just as any purchase must be made public.
