Have you thought about the flip side of it? When these big corporates are buying Bitcoin in bulk, the price is increasing. A lot of people sharing about it.
But what would happen if these corporates start selling their Bitcoins in bulk? The price will start dropping.
With 1.5 billion worth of holding, these corporates hold the power to manipulate crypto market. I hope no company start buying Bitcoin anymore!
Not really. They are not buying a lot of Bitcoin but rather a lot of the current value in Bitcoin. If you buy 10000 Bitcoin for 1 cent each coin, you would have much more power over the Bitcoin price than if you bought 10000 Bitcoin at the price of 70k each coin. Why? Because it does not matter at what price you dump the 1 cent coins, you will make an immense profit.
But dumping so many Bitcoin at the price of 70k? That is hard to do without incurring a huge loss. Since they made the investment at 70k, selling the vast amounts AND making a profit at the same time is hard, time-intensive work.
In other words,
nobody is going to buy mass amounts of Bitcoin only to employ the "pump and dump" strategy. It just is not feasible anymore.
