No, BlackRock Can’t Change Bitcoin

Recently, BlackRock released an educational video explaining Bitcoin, which I thought was great—it’s amazing to see Bitcoin being discussed on such a massive platform. But, of course, Bitcoin X (Twitter) had a meltdown over one specific line in the video: “There is no guarantee that Bitcoin’s 21 million supply cap will not be changed.”

HealthRnager from Natural News claimed, “Bitcoin has become far too centralized, and now the wrong people largely control its algorithms. They are TELLING you in advance what they plan to do.”

Now, let me be clear: this is total nonsense. The controversy is overhyped, and the idea that BlackRock would—or even could—change bitcoin’s supply is laughable. The statement in their video is technically true, but it’s just a legal disclaimer. It doesn’t mean BlackRock is plotting to inflate bitcoin’s supply. And even if they were, they don’t have the power to pull it off.

Bitcoin’s 21 million cap is fundamental—it’s not up for debate. The entire Bitcoin ecosystem—miners, developers, and nodes—operates on this core principle. Without it, Bitcoin wouldn’t be Bitcoin. And while BlackRock is a financial giant and holds over 500,000 Bitcoin for its ETF, its influence over Bitcoin is practically nonexistent.

Bitcoin is a proof-of-work (PoW) system, not a proof-of-stake (PoS) system. It doesn’t matter how much bitcoin BlackRock owns; economic nodes hold the real power.

Let’s play devil’s advocate for a second. Say BlackRock tries to propose a protocol change to increase bitcoin’s supply. What happens? The vast network of nodes would simply reject it. Bitcoin’s history proves this. Remember Roger Ver and the Bitcoin Cash fork? He had significant influence and holdings, yet his version of bitcoin became irrelevant because the majority of economic actors didn’t follow him.

If Bitcoin could be controlled by a single entity like BlackRock, it would’ve failed a long time ago. The U.S. government, with its endless money printer, could easily acquire 10% of the supply if that’s all it took to control Bitcoin. But that’s not how Bitcoin works. Its decentralized nature ensures no single entity—no matter how powerful—can dictate its terms.

So, stop worrying about BlackRock “changing” Bitcoin. Their influence has hard limits. Even if they tried to push developers to change the protocol, nodes would reject it. Bitcoin’s decentralization is its greatest strength, and no one—not BlackRock, not Michael Saylor—can change that.
