The ฿ symbol already has an official Unicode name "THAI CURRENCY SYMBOL BAHT".

Unless bitcoin change its name to "Bahtcoin", we should not mess with other countries currency symbol.

Especially the ฿ symbol is only used exclusively for the Thai Baht now, I am sure they will have a strong attachment and ownership feeling towards this symbol.

If I were Thai, i would not be happy about that.

People using the $ may not have such feelings, because so many other currencies are using the $ symbol.

It takes a long time for Unicode to adopt a new character. Something that is already in Unicode is much more convenient. Once adopted, people all over the world can use it, type it (or at least copy and paste) it immediately.

Bitcoin don't have to have a currency symbol, but a currency is really a logo, an identity. Bitcoin is for the electronic medium. It is international. For example, if shown on a shopping website, people knows straight away that the price shown is in Bitcoin (but not Thai baht!).
