US businessman and investor Robert Kiyosaki has warned of a possible collapse of the US dollar if BRICS launches a gold-backed cryptocurrency.
A BRICS cryptocurrency may cause US dollars to "come rushing back to home to America causing hyperinflation in America," the founder of the Rich Dad company said on social networks.
"Best buy real gold, silver, and Bitcoin now, and protect yourself from the crash of US dollar," he added.
In March, Russian Ambassador to the United States Anatoly Antonov told Sputnik that the bloc can eventually switch to a new payment system based on digital currencies or use blockchain.
