The former governor of the Central Bank of Brazil has heaped praise on Bitcoin – and suggested that McDonalds and Starbucks follow suit with Facebook, and consider launching cryptocurrencies of their own.“In theory, any global company – not just big IT enterprises could do something similar [to what Facebook proposes to do with Libra]. McDonald's could create the ‘Mac,’ a cryptocurrency that could be converted into Big Macs. Starbucks could create the ‘Star,’ letting people buy cappuccinos – all based on blockchain technology. Why not?”
