btc max price
Hello everyone,
I've been playing around with some numbers and wanted to share the idea (maybe someone will correct me if I'm wrong).
If we think of a scenario where BTC was the only global money, we can use the equation of exchange:
M \times V = P \times Y
Where:
= money in circulation (BTC × price).
= velocity of money (how many times it rotates per year).
= World nominal GDP.
Global nominal GDP today is around USD 113–114 trillion (IMF 2025).
The useful supply of BTC is ~18 million (discounting those that have been lost).
So, solving:
\text{BTC Price} = \frac{GDP_{\text{world}}}{V \times 18,000,000}
If we take typical values of (between 3 and 6), it gives us a range:
V = 3 → ~2.1M USD/BTC
V = 4 → ~1.6M USD/BTC
V = 5 → ~1.3M USD/BTC
V = 6 → ~1.0 M USD/BTC
That is, for BTC to cover the global money function and “replicate” the current money supply, it would need a value in the range of ~1–2 million USD per BTC (perhaps up to 3–4 million if we use a lower money velocity or consider lost BTC).
Obviously, this calculation is theoretical and simplified:
It does not contemplate future GDP growth.
It does not contemplate that States will continue printing fiat currency in the meantime → therefore the “equilibrium price” would move higher over time.
It also does not consider strategic reserves, savings, immobilized BTC, or credit dynamics that could modify the speed.
The intention is to have a more or less well-founded idea of what the BTC ceiling may be until it stabilizes and enters a stage of slow delation that makes it more useful as cash and not so much as a speculative asset or reserve of value.
Does this reasoning make sense or am I missing something key?
