Could BlackRock manipulate the market and crash USDT to buy low?

BlackRock, the world's largest and strongest asset manager with over $8 trillion in assets under management, has officially entered the crypto market in 2023. They have filed for a Bitcoin Fund and are probably planning to dump prices so they can buy low.

I find myself contemplating whether they figured out a way of making a load of money while simultaneously screwing over the whole crypto market. Could it be that they intend to disrupt USDT in the pursuit of enhancing crypto security, resulting in a market price downturn that allows them to capitalize on lower prices?
