On February 5, 2010, a user on the bitcointalk forum with the nickname NewLibertyStandard first proposed defining a symbol for Bitcoin, as well as deciding on a ticker for the cryptocurrency, which would facilitate the exchange of Bitcoin for traditional currencies, goods, and services.
As a symbol, he suggested borrowing the Thai baht symbol, which subsequently led to the creation of the unique and well-known Bitcoin logo today. As for the ticker, NewLibertyStandard proposed BTC, which is globally used today.
