Fortaleza, the fifth-largest city in Brazil with a population of about 2.7 million, is set to accept bitcoin (BTC) payments for public transportation by the end of this year. Local news outlet O Povo reported the news late last week, saying that the Ceara State Co-operative Autonomous Passenger Co-operative (Cootraps) will provide Fortaleza citizens the options to buy bus tickets using bitcoin, credit and debit cards, in addition to the current cash system.
