I have always been intrigued by a basic question: how much money actually exists in the world? And when you start to investigate, you discover something fascinating that explains many things about why they say there isn't enough money for Bitcoin to keep growing.

Let's look at the numbers. In physical cash, bills and coins, there are about $9 trillion. It sounds like a lot, but it's just the tip of the iceberg. The real magnitude is in bank accounts and deposits: we're talking about around $100 trillion in regular deposits, and another $150 trillion in large deposits and investment funds.

Now, when you add up how much money exists in the world in real terms, the total is around $150 trillion. But here’s the interesting part: nearly $62 trillion of those dollars are concentrated in the United States. China follows with about $16 trillion, and Japan rounds out the top three with $6.5 trillion. That means the U.S. controls almost half of the global money market.

Of course, there are more than 1 quintillion dollars in global financial assets if you include stocks, bonds, and derivatives, but that’s no longer money in the traditional sense—those are valuations. The real money, the one that counts, is that total of $150 trillion.

So when you hear that there isn’t enough money for Bitcoin to grow further, reality shows you something completely different. There’s plenty of money. What matters is understanding who controls it and what decisions they make. That’s what truly determines where capital flows in the coming years.
