A perpetual has no fixed maturity at which its price must converge to spot. Even a broadly price-neutral position has a path of cash flows, collateral requirements and possible forced closure.","当两边价格分化、数量变化或一侧无法交易时，抵消并不完整。永续合约没有一个价格必须与现货收敛的固定到期日。即使组合整体接近价格中性，也仍有现金流路径、抵押要求和被迫平仓的可能。"]]},{"heading":["Rewards attach to qualifying holdings, not to a guaranteed yield","奖励来自合资格持有，不是保证收益"],"paragraphs":[["Binance describes HODLer Airdrops as rewards tied to historical snapshots of qualifying BNB balances in specified products.

Rewards that remain unsold need an explicit valuation time and liquidity assumption, rather than being silently treated as cash.","净结果需要合并两边盯市变化、带符号资金费、实际奖励与合资格利息，再扣除全部成本。空投代币显示的开盘价不一定是接收者能卖出的价格；未卖出的奖励需要明确估值时点与流动性假设，不能默认为现金收入。"],["The denominator should include the spot inventory, derivative margin and capital reserved to keep the arrangement operating, without double-counting collateral.
