Bitcoin is the world’s first decentralized cryptocurrency and one of the most widely recognized digital assets. Alongside its name, Bitcoin has a distinct symbol: ₿. Much like the dollar ($), euro (€), or rupee (₹), the Bitcoin sign provides a shorthand way to represent the currency. This guide explores the history, design, encoding, and usage of the Bitcoin symbol in detail.
What Is the Bitcoin Symbol?
The official Bitcoin symbol is ₿. It is used to represent the cryptocurrency Bitcoin, whose currency code is BTC (and sometimes XBT in financial systems). Just as $ stands for dollars and € for euros, ₿ stands for Bitcoin.
Origin and Design
The Bitcoin symbol has an interesting evolution:
- The design resembles the Latin capital letter B with two vertical strokes (₿), much like the $ uses an “S” with strokes.
- The symbol was inspired by existing currency marks to make Bitcoin look familiar and credible as money.
- Before ₿ was standardized, many people simply used BTC, or a regular capital “B” with one or two vertical bars added in images and logos.
- The double stroke is typically drawn through the upper and lower parts of the B, not the entire glyph, giving it a distinct look.
Unicode and Encoding
For digital representation, the Bitcoin symbol was officially added to Unicode in 2017:
- Unicode: U+20BF
- HTML code:
₿or₿ - Character: ₿
- Unicode Version: 10.0
Before Unicode adoption, users relied on images, fonts, or the ticker code BTC for Bitcoin.
How to Type the Bitcoin Symbol (₿)
Typing the Bitcoin symbol depends on your operating system, software, and fonts:

Bitcoin Symbol vs. Ticker Codes
In practice, the Bitcoin symbol ₿ and the ticker codes BTC or XBT are both used. Here’s how they compare:
| Representation | Meaning | Where Used |
|---|---|---|
| ₿ | Bitcoin currency symbol | Informal writing, websites, apps, digital wallets |
| BTC | Bitcoin ticker code | Exchanges, financial reports, trading platforms |
| XBT | ISO-like code for Bitcoin | Banks, international finance systems |
Examples of Usage
- Retail: “Coffee available for ₿0.00025.”
- Exchange rates: “₿1 = $25,000.”
- Trading platforms: “Deposit BTC (₿) into your account.”
- Informal writing: “He invested ₿2 last year.”
Why the Symbol Matters
- Recognition: Having a distinct currency symbol legitimizes Bitcoin as a medium of exchange.
- Clarity: Helps avoid confusion with abbreviations or other terms.
- Brand identity: The ₿ symbol has become a strong visual brand associated with Bitcoin adoption.
Other Cryptocurrency Symbols
Bitcoin is not alone in having a unique symbol. Other cryptocurrencies also use marks or icons, though few are in Unicode yet:
- Ethereum: Ξ (Greek Xi character, adopted informally)
- Litecoin: Ł
- Dogecoin: Ð (capital eth character, used informally)
However, Bitcoin remains the only cryptocurrency with an official Unicode currency symbol.
FAQ
Is ₿ an official ISO symbol?
No. The ₿ is recognized in Unicode and widely used, but the official ISO 4217 code for Bitcoin is not yet assigned. Some financial systems use XBT to align with ISO naming conventions.
Do all devices support the ₿ symbol?
Not always. The symbol was added in Unicode 10.0 (2017), so older systems or outdated fonts may not display it correctly. In such cases, “BTC” is safer.
Why are there two vertical strokes in ₿?
The design was influenced by the $ sign, which also uses strokes. The double stroke emphasizes stability and credibility as a currency symbol.
Conclusion
The Bitcoin symbol (₿) has grown from a community-made design into a globally recognized sign, supported in Unicode and used across apps, wallets, and websites. It represents Bitcoin in the same way $ represents dollars, and it provides both legitimacy and clarity in financial contexts. While BTC and XBT remain essential in trading and banking, ₿ continues to grow as the shorthand symbol of the digital currency revolution.
