Why Everyone Says ETH Supply is "Infinite" (But It's Not Quite)

ETH is down 8.68% today, trading at $3,139.27. But here's a deeper question that confuses a lot of people: Why doesn't Ethereum have a supply cap like Bitcoin?

The Numbers First

As of March 2025, there are about 120-122 million ETH in circulation. Bitcoin has a hard limit of 21 million. ETH? No ceiling. That's where the "infinite supply" meme comes from.

Where New ETH Comes From

Before September 2022, Ethereum miners were printing roughly 18 million ETH per year from block rewards. Post-Merge (when Ethereum switched to Proof of Stake), that dropped dramatically to 0.5-1 million ETH annually paid to validators.

The key thing: There's no date when it stops. No "halving" countdown like Bitcoin. That's the real reason people panic—it feels endless.

The Burn Mechanic Changes Everything

Here's what most people miss: EIP-1559 (August 2021) started burning ETH.

Every transaction fee gets partially destroyed permanently. During bull runs, the burn rate can actually exceed new issuance—meaning ETH temporarily becomes deflationary. Millions of ETH have been vaporized already.

Why Vitalik Chose This Path

Vitalik and the Ethereum team deliberately rejected a hard cap. Their reasoning: if rewards end, validator incentives die, and the network becomes less secure (a problem Bitcoin might face after 2140).

Instead, they're using economic design (issuance + burning) to manage supply—similar to how central banks manage money supply, not a fixed rule.

The Real Story

ETH isn't "infinite." It's dynamically managed. New coins enter slowly, old coins leave fast during peak usage. It's not Bitcoin's fixed scarcity, but it's also not the printer going brrr forever. The supply adjusts based on network activity—more transactions = more burn = potentially deflationary.

So when someone says "ETH has infinite supply," they're technically right about the cap, but missing the mechanism.
