Bitcoin isn't 21 million coins. It's 2.1 quadrillion satoshis. Keep that in mind the next time someone says there won't be "enough."

Eli Ben-Sasson, a Zcash co-founder, wants to swap Bitcoin's fixed cap for 4% annual issuance, worried that lost coins leave too little to go around. Start with the obvious part. The 21 million cap is the product. Change it and you don't have Bitcoin anymore. You have another coin that borrowed the name.

Now the "just 4%" part. There is no just once. The moment the cap can move, someone owns the dial, and 4% stops being a ceiling and becomes a precedent. Every future emergency will argue for a little more. That is the entire history of fiat money, restarted from scratch.

And the shortage he fears isn't real. Each Bitcoin splits into 100 million sats. When coins are lost, the ones that remain simply carry more value, and the network keeps pricing life in smaller units. Lost coins don't starve you. They make everyone else's sats worth more.

A cap you can vote to raise was never a cap. It's fiat with extra steps.
