Mt.Gox is the world’s largest and most established Bitcoin exchange that facilitates the trade of Bitcoin for local currencies around the world, quickly and securely.
All Mt.Gox customers have at least two sub-accounts: one for Bitcoins (BTC) and one for their local currency (eg. USD). Bitcoins can be purchased using funds sent from the customer’s bank account to their Mt.Gox account. Balances from the sale of Bitcoins can also be withdrawn in local currency to the customer’s bank account.
MtGox was originally created by Jed McCaleb in July 2010, and was sold to Tibanne Co. in Japan in March 2011. It is currently operated by Tibanne Co.Ltd. managed by Mark Karpeles (@MagicalTux).
