BlackRock, a big company, used to dislike Bitcoin, but now they see it can make them lots of money. Now they want to make money from other assets, not just $BTC . They want to turn everything into digital tokens. But this plan might not be good. Some journalists found out that BlackRock's plan could be sneaky. Just because something is on a blockchain doesn't mean it's safe from control. So, even though BlackRock has helped Bitcoin grow, we should be careful about trusting them. They might not have good intentions.
