Bitcoin deserves the right symbol.
Why should the Bitcoin community adopt this symbol? Since the birth of Bitcoin, a large number of logos and symbols have been introduced. The most popular is a bold falling serif B, intersected by two vertical dashes à la U.S. dollar.
The problem is that the image on the left is a logo! It’s a unique image file, just like it could be used by a company to sell or promote a product. Currencies are represented by symbols like $, € or ¥, aiming to be used everywhere by everybody. The Thai Baht ( ฿ ) is sometimes used to represent Bitcoin, but this certainly raises a problem of differenciation between the Thai Baht and Bitcoin.
