What Happens When... Crypto Edition

So there's been a lot of talk and hype around major companies buying bitcoin including what MicroStrategy. But what happens when these companies that are buying up droves of crypto start to cash out? Do you really think MicroStrategy, Blackrock etc are just going to gobble up tons of these assets and sit on them forever?

This centralization nature that's currently happening with Bitcoin could be it's downfall as there are now rumor's that Blackrock wants so much bitcoin that they have control over it. What's crazy is they could do it because the entire market cap of bitcoin is still crazy low compared to the amount of money in other assets and fiat. Heck selling off just about 20% of gold could buy you nearly all the bitcoin that exists as long as people wanted to let it go.

At some point these companies are going to sell off and take profits and also use their vast holdings to trigger manipulations in the markets like whales have been doing for years.
