Story Highlights Crypto analyst Deso accuses Tether of using risky financial loops and borrowed funds instead of real USD to back USDT. Tether's HQ move to El Salvador and claims of $150B USDT control by its co-founder spark further concerns over transparency. A viral post on X by crypto analyst Deso has raised serious questions about the stability of Tether (USDT)—the world’s largest stablecoin. Deso claims Tether may not be fully backed by real US dollars, but instead by borrowed money and risky financial loops, potentially endangering the entire crypto market. Analyst Warns of Ponzi-Like Structure Behind Tether Tether, designed to maintain a 1:1 peg with the US dollar, is widely used in crypto trading and DeFi. However, Deso alleges that real dollar backing may be missing. According to his analysis, firms are leveraging borrowed funds to buy USDT, converting it into crypto like Bitcoin, and then selling it for dollars—repeating the cycle. The key players he names: Abraxas, Cumberland, and Wintermute. These firms allegedly rely on high crypto prices and constant demand to sustain the loop. If prices fall or demand dries up, the system could collapse, leaving borrowed money unpaid—a setup Deso likens to a Ponzi scheme. Tether’s El Salvador Move Raises Eyebrows In a separate post, Deso highlighted that Tether recently shifted its headquarters to El Salvador, a nation without an extradition treaty with the U.S. He also flagged that Tether’s co-founder, Giancarlo Devasini, now controls at least $150 billion in USDT, as per blockchain tracking tools like Arkham Intelligence. Deso has called on journalists, investigators, and the wider crypto community to scrutinize Tether’s reserves and operational practices more closely.
