Blockchain is helping gamers make money. ‘F1 Delta Time’, is an auto racing game that’s built on blockchain technology and allows players to exchange the in-game currency ‘Revv’ for Bitcoin, or USDT. Hong Kong-based Animoca Brands is the publisher of F1 Delta Time as well as other play-to-earn blockchain games including The Sandbox. This type of play-to-earn online game is on the rise, with Animoca raising US$88.8 million at a US$1 billion valuation last month. Photo by Animoca
