Compreender claramente os incentivos e os fatores econômicos por trás de cada opção de Blockchain pode poupar muitos problemas futuros, de escolhas erradas Antes só havia Bitcoin...uma moeda virtual, libertária, que prometia acabar com o atual sistema financeiro. Começou meio escondida, circulando apenas no meio nerd (a primeira compra de Bitcoin conhecida ocorreu em 2010, quando o hacker Laszlo Hanyecz comprou duas pizzas no Papa John's com 10.000 Bitcoins), até que por volta de 2015 os bancos a descobriram. Mas, ao estudar o Bitcoin, viu-se que havia algo muito maior por trás dele, a tecnologia Blockchain. Os bancos, que antes olhavam Bitcoin com desconfiança viram uma oportunidade de redução de custos, uma vez que Blockchain permite transações financeiras sem intermediários para validá-las.
