History: Due to a confusion of names and the fact that there are two different entities using the name 'BitBay' (a cryptocurrency and a cryptocurrency exchange), we regret to inform that the 'History' section of the BitBay article refers to the cryptocurrency exchange, not the cryptocurrency BitBay (BAY) that is the subject of the article. Also, the end of the penultimate sentence: "an exchange - it even offers its users a credit card linked to their account that can be used to make purchases or withdraw cash from ATM machines" once again pertains to the cryptocurrency exchange and not the cryptocurrency.
