Many people see USD1 listed on Binance Futures, and their first reaction is: Oh, another stablecoin trading pair. But those who truly understand derivatives are looking at something else—USD1 is already starting to compete for the position of 'underlying settlement currency for exchanges.' The launch of BTCUSD1 perpetual contracts is just the surface; it directly enters the highest collateral tier in Portfolio Margin. This means USD1 isn’t just a stablecoin to hold—it can be used directly as margin, collateral, and the core asset of liquidity pools. Whoever controls the collateral layer controls the liquidity gateway of the entire derivatives market. In the past, stablecoins competed on 'who’s more like the US dollar.' Now, it’s about 'who can drive the trading system.' WLFI’s strategy clearly isn’t just about payments anymore—they’re pushing USD1 toward becoming an on-chain USD operating system. While many are still analyzing token prices, the real big money is already studying which stablecoin will become the foundational layer for global trading in the future.
