Multi-Asset Mode is cross-margin only, can auto-exchange assets when balances or LTV conditions breach thresholds, and charges hourly interest on negative USDT/USD1 balances beyond a -1,000 USD exemption. The current annualized rate is documented as 4%.",

      "label": "Provider-reported",
      "finding": "Maximum transfer formulas still depend on wallet balance, margin requirements, open orders and unrealized PnL, with different calculations for cross and isolated margin. The page explicitly notes that transferring out margin can raise liquidation risk.",

      "consequence": "Separate fee credits from collateral and withdrawable value. BonusUSD can support trading but is not equivalent to cash; AFEE cannot replace collateral.",

      "consequence": "TWAP is an execution-management tool, not a fill guarantee. Margin sufficiency, liquidity and volatility can interrupt or distort execution.",
