I propose that we adopt the Thai baht currency symbol, ฿, as the official bitcoin currency symbol and BTC as the official bitcoin three letter currency code.
The proposal sparked discussion among early community members, with some concerned that sharing the baht symbol (฿) could cause confusion with the Thai currency.
Later, on November 1, 2010, forum user “bitboy” designed what became the iconic Bitcoin logo: a white B crossed by two vertical strokes, on an orange circle, tilted 14 degrees clockwise. Two weeks later, after Satoshi asked that contributed graphics be made public domain, bitboy released his into the public domain.
“BTC” remains the common code. The symbol in common use today is not the baht sign but ₿, the logo’s two-stroke B, added to Unicode in 2017. The currency code “XBT” was later proposed as an ISO 4217-compliant alternative (since “BT” is Bhutan’s country code), but “BTC” remains far more widely recognized.
