Australia’s first bitcoin ATM has gone live in central Sydney, allowing passersby to buy and sell the digital currency and exchange it for cash. The orange machine, which resembles a regular banking ATM, was unveiled on Tuesday morning inside a Westfield mall on Pitt St. The machine – the first of several to be rolled out across the country – will make it easier for regular people to deal in bitcoin, said co-owner Chris Guzowski, CEO of ABA Technologies.
