The Bitcoin symbol (₿) represents more than just a currency—it's an icon of decentralization and digital finance. This guide explores its history, Unicode adoption, and practical usage.
The Official Bitcoin Symbol ₿
The universally recognized Bitcoin symbol is ₿, a capital letter "B" with two distinctive strokes at the top and bottom. This design was:
- Created by Satoshi Nakamoto for early Bitcoin client icons
- Replaced initial "BC" abbreviations in original software
- Intentionally resembles traditional currency symbols (like $ or €)
This symbol represents:
- The currency unit "bitcoin" (100 million satoshis)
- The Bitcoin network itself
- The broader cryptocurrency movement
Informally, Bitcoin is often abbreviated as BTC, though this violates ISO 4217 standards (as "BT" is Bhutan's country code).
Unicode Adoption and Font Support
The ₿ symbol achieved major milestones:
| Year | Milestone |
|---|---|
| 2011 | Initial Unicode proposal rejected |
| 2015 | Accepted into Unicode standard |
| 2017 | Released in Unicode 10.0 (U+20BF) |
Current font support includes:
- macOS Sierra and iOS
- Android O beta
- Windows 10 Creators Update
- Major Linux distributions

Alternative Representations Before Unicode
Before official adoption, users employed creative substitutions:
Thai Baht symbol (฿)
- Visually similar but geographically confusing
Capital B with stroke (Ƀ)
- Used in technical contexts
Image replacements
- Guaranteed visibility but lacked typographic flexibility
Official Currency Code: XBT vs. BTC
The cryptocurrency landscape recognizes two primary codes:
XBT (ISO 4217 compliant)
- The official proposed standard
- "X" denotes non-country currencies
- Currently unofficial but gaining adoption
BTC (Common usage)
- Widely recognized in exchanges and wallets
- Violates ISO country code rules
- Likely to remain popular despite standardization efforts
The Bitcoin Foundation is working to formalize XBT through ISO 4217 channels.
