Tether is looking for a deal that would push its valuation to $500 billion, and if that happens, Giancarlo Devasini would end up with a net worth of $224 billion, putting him ahead of Warren Buffett, right behind Elon Musk, Jeff Bezos, Larry Ellison, and Mark Zuckerberg. This info came from the Bloomberg Billionaires Index, and it’s based on what Devasini would pocket from his ownership stake if Tether Holdings pulls this off and becomes one of the most valuable private companies on the planet.
