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.
It appears to be a Dollar sign and I figure we should have to go something different since its like opposed to duplicating USD.
The more significant thing is people may think its a trick/scam and a duplicate feline of USD. They can ridicule it and deceiving it would be harmful to what's to come.
For me I concur with the 3 three-letters there's nothing incorrectly with it and can be worth around the world.
