The growth of online virtual worlds will help advance the mainstream adoption of cryptocurrencies for payment transactions but it won’t be a game-changer, according to Frédéric Chesnais, chief executive of French fintech company Crypto Blockchain Industries. In blockchain-based 3D virtual worlds, often referred to as metaverses, users can purchase and trade virtual assets and services using cryptocurrencies. “I think it will be important but I don’t think this is the key turning point,” Chesnais, who was until earlier this year the CEO of videogame company Atari told a Reuters NEXT panel on Thursday.
