Argentines are increasingly turning to stablecoins to capitalize on price discrepancies between the official and parallel peso markets, achieving up to 4% profit per transaction. This crypto-based arbitrage strategy, known as the 'rulo,' has gained traction as President Javier Milei enforces stricter foreign exchange controls. Traders convert U.S. dollars into stablecoins such as USDT or USDC, then resell them for pesos at a weaker market rate. The popularity of this practice has surged, with platforms like Ripio, Lemon Cash, and Belo reporting significant growth in stablecoin-to-peso transactions. Experts highlight that stablecoins are becoming a financial refuge for Argentines amid the country's ongoing economic instability.
