方法论与数据源
资金流聚合自 SoSoValue 的公开美国现货 ETF 数据（与其仪表盘渲染的同一序列），覆盖全部上市基金（比特币：IBIT、FBTC、GBTC、ARKB、BITB 等；以太坊：ETHA、ETHE、FETH 等）。净流入代表当天进入基金的资金多于离开的资金；净流出则相反。
已结算的美国交易日进入永久每日表。当日数字在发行商结算前为暂计并有相应标注；次日早晨的复查会收录修订。周末与美国休市日没有资金流，因此这些日期直接缺席，而不是显示为零。
按基金的行自我们于 2026-07-31 开始追踪起累积，因为公开数据源仅提供每只基金的当日数据。聚合每日序列则可回溯约 14 个月。

比特币 ETF 资金流能预测价格吗？
资金流是结构性需求：每一美元净流入都会转化为真实的现货买盘。单日数据噪音较大，但自 2024 年 1 月 ETF 上市以来，数周维度的资金流趋势对比特币中期方向的指示优于多数情绪指标。
