Cryptocurrency firm Tether plans to move its headquarters to El Salvador, as the founders behind the world's biggest stablecoin look to capitalise on the Central American country's bid to become a hub for crypto trading. Tether has emerged as a dominant force in the booming market for stablecoins, which are designed to maintain a constant value by being pegged to traditional currencies and offer users a way to move money between cryptocurrencies without being exposed to price swings. CEO Paolo Ardoino told Reuters Tether would relocate to El Salvador after Tether recently got a digital asset service provider licence there, and that he and other management as well as co-founders were relocating to live there.
