Its core function is: Can be used as margin: Users can use LDUSDT as margin for Binance futures trading (U-based contracts) and participate in high leverage derivative trading. Users holding LDUSDT can also earn profits: At the same time, they can continue to receive real-time annualized rate of return (APR) from Binance's "breakeven earning coins" current products, similar to deposit interest. Simply put, LDUSDT eliminates the need for users to choose between "saving money to make money" and "trading with money". Funds can play both roles simultaneously, balancing liquidity and profitability.
