3 月 21 日，Greeks.live 分析师 Adam 在社交媒体上发文表示，“3 月 21 日期权交割数据：2.2 万张 BTC 期权到期，Put Call Ratio 为 0.84，最大痛点 85000 美元，名义价值 18.3 亿美元。13.3 万张 ETH 期权到期，Put Call Ratio 为 0.62，最大痛点 2000 美元，名义价值 2.6 亿美元。
本周市场相对平淡，期权的交割总量下降了近一半，短期隐含波动率 IV 明显下降，BTC 中短期波动率全面跌破 50%，ETH 中短期波动率也回到了 60% 附近，短期波动率接近腰斩。加密货币进入一种自由振荡的横盘状态，投资者情绪开始变得迟钝，时间接近季度交割，大户一般在这个时候也是求稳为主。
期权做市商机构重新提高卖出的强度，收紧 IV，这是在押注未来短期横盘。近期加密货币确实没有太多重要事件，不确定性大大降低，做市商抓紧时间回收利润，买方在这两周会比较难做。”
