I'm still ok with the Thai Baht symbol. It's not like the dollar sign is uniquely used. (Canadian, Australian, Brazilian Real, ...) but those currencies have a historical tie, unlike bitcoin and Baht.
I am not a fan of using the Thai Baht, but don't care much. None the less here's my contribution (not Unicode) which emphasises bitcoin's cryptographic hash (#) backed nature.

But it turns out the Baht was a unit of weight that was originally base 2 - binary!
