Bitcoin's volatility makes pricing hard
Imagine pricing a cup of coffee at 0.000004 BTC on Monday. By Friday, that same amount might be worth half as much — or double. Businesses cannot plan around this, and most people won't quote prices in a unit that can swing 10% in a day.
This is not a flaw in Bitcoin. Volatility is what you see when a fixed-supply asset is being price-discovered across the entire world over decades. But it is a real friction for anyone who wants to use Bitcoin as money right now.
Meet ₿C — Bitcoin Currency
₿C is a unit of account derived entirely from Bitcoin's own price history. It is computed as the cumulative average of every daily Bitcoin price going back to the genesis block in 2009. No institution controls it. No one can change it. It is simply mathematics applied to the public record.
Today, one ₿C is worth roughly $18,000–$20,000 USD — about one-fifth of Bitcoin's current spot price. That gap will close slowly, over years and decades, as today's high prices are absorbed into the long-run average.
Because it averages across 6,000+ days of history, ₿C barely flinches when Bitcoin has a good or bad week. A 40% crash in Bitcoin spot moves ₿C by less than one-twentieth of one percent on that day. Over the long run, as Bitcoin's price climbs, ₿C climbs too — gradually and predictably.
₿C is not a stablecoin. It does not peg to a dollar or any government currency. It is a Bitcoin-native unit that appreciates steadily with Bitcoin's long-run trajectory while absorbing short-term volatility entirely.
Three applications built on the same foundation
₿C is a building block. Below are three concrete applications that become possible once you have a stable, Bitcoin-native unit of account. Anyone can use ₿C to help build the Bitcoin economy.
Pricing & Commerce in ₿C
Merchants and individuals can denominate goods, services, and contracts in ₿C. Day-to-day prices stay stable. Long-run, both sides of the transaction benefit from ₿C's steady appreciation against fiat.

A Bitcoin-denominated bond instrument that uses ₿C as the benchmark return. It gives Bitcoin holders a way to deploy capital productively without leaving the Bitcoin system.

A USD-pegged stablecoin fully backed by Bitcoin reserves held by a consortium of public Bitcoin treasury companies. A dollar for the Bitcoin era — not issued by any government.

The Bitcoin economy and the fiat economy are two different worlds. ₿C serves a different role in each.
₿C is used to price goods, services, and bonds directly in Bitcoin terms. Volatility is absorbed. Prices quoted in ₿C remain meaningful from one week to the next.
₿USD uses Bitcoin reserves — valued at the ₿C price — to back a dollar-pegged token. It lets fiat users transact in a familiar unit while the underlying reserve appreciates in Bitcoin terms.
Both applications are independent. You do not need ₿USD to use ₿C for pricing. Both solve their own problem in each economy and ₿C is the thread that runs through both of them.
An open foundation
The BTCADP price standard and the ₿C protocol are published as public domain under CC0 — no patents, no licenses, no fees. Anyone can implement them, build on them, or critique them.
The three applications described here are proposals, not products. They exist to demonstrate that a stable, Bitcoin-native unit of account unlocks things that were not previously possible. What else gets built on this foundation is an open question.
