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.
Also an existing Unicode char would be easier. Just my 0.5 BTC.
Imo bitcoin is about freedom and no restrictions, no need to force those rules on it. Let it grow and eventually one symbol will stand out and live on.
Meanwhile enjoy the creative results that flow out of this initiative.
Not my best English, but iPad and autocorrect... Sheesh!
