Bitcoin symbol ₿

• Ticker code: BTC is the most common code on exchanges and in news. Some financial systems use XBT.
• Symbol or code: both ₿0.05 and 0.05 BTC appear. The code after the number is more common in tables and price lists; the symbol shows up in logos, headlines and app interfaces.
• Decimals: one bitcoin divides into 100,000,000 satoshis (sats), so amounts like 0.00025 BTC are normal. Show enough decimal places that readers can compare values, and align decimals in tables.

This page covers the symbol only; nothing here is investment advice.

• ฿ (Thai baht sign) is the currency symbol of Thailand. Before ₿ had its own code point, many people borrowed ฿ for bitcoin, and you will still see it in older posts. Avoid it now: it stands for a real national currency.
• Ƀ (Latin capital B with stroke) is a letter with one horizontal stroke, not a currency sign.
• $ sometimes appears next to BTC to show a dollar price; it is not a bitcoin sign.

Because ₿ is relatively new, some older fonts lack it and show an empty box or a fallback glyph from another font. If the sign matters to your design, test it in the fonts your readers will actually see.

• Windows: in Word, use the Alt+X code from the table above; elsewhere, copy and paste.
• Mac: open the Character Viewer with Control+Command+Space and search “bitcoin.”
• Phones: copy it once and save a text replacement such as “btcsign” → ₿.
• Websites: choose a web font that includes ₿, or list a fallback font in your CSS so the system font fills the gap.
• LaTeX: with XeLaTeX or LuaLaTeX, type it directly when your font has the glyph.
• Data: store the code BTC, not the symbol, in databases and spreadsheets.
