周五（7月17日）纳指标普继续走弱的同一天，比特币现货ETF却净流入1.32亿美元，这已经是连续第4个交易日保持净流入。放在过去一个月的背景下看，这种币价跟美股走势脱钩的情况并不常见——通常两者会同涨同跌。
这背后其实是一场拉锯战。我们此前的BTC研判就一直在追踪一个矛盾：一边是ETF资金持续流出、场外买家迟迟不现身；一边是恐慌贪愿指数已经跌到25分的极度恐慌区间，逆向反弹的规律又让判断不敢轻易转空。这两股力量互相拖拽，让立场几乎每周都在中性和谨慎看空、看多之间来回摆。这次连续4日净流入，算是多头这边新添的一块砝码。
但故事还有另一面。同期稳定币（锚定美元的加密资产，常被当作场外待入场的"弹药"）总市值7天缩水1.09%，说明场外真正的增量资金其实在减少，而不是增多。也就是说，这波ETF资金更像是存量资金在搬家，而非全新买盘涌入。再往远看，7月16日的判断还提到，BTC在14天维度上仍是净流出16亿美元的大背景，这个底色并没有变。
以太坊那边同一天净流入3672.64万美元，贝莱德的ETHA一家就占了3167.9万美元，机构偏好依然集中在头部产品。
接下来两天美股闭市，ETF资金流数据会暂停更新，最新这份"连续4日净流入"的读数会一直挂在那里，直到下一个交易日揭晓这场拉锯战的下一步。
On Friday, July 17, while the Nasdaq and S&P kept sliding, Bitcoin spot ETFs quietly pulled in $132 million — the fourth straight day of net inflows. That's an unusual split from the past month's pattern, where crypto and stocks mostly moved together.
We've been tracking this tug-of-war in our BTC coverage for weeks: on one side, ETF outflows and no fresh buyers showing up; on the other, a Fear & Greed Index stuck at 25 (Extreme Fear), where the market's own "don't turn more bearish during panic" logic keeps kicking in. Those two forces have kept the stance flipping between neutral and cautiously bearish or bullish almost weekly. This four-day inflow streak is the latest piece of evidence tilting toward the bulls.
But there's a catch. Over the same week, total stablecoin market cap — often seen as sideline cash waiting to buy the dip — shrank 1.09%. That suggests the real pool of new money isn't growing. What's flowing into ETFs looks more like existing capital reshuffling than genuinely fresh demand. And zooming out, BTC was still sitting on a 16-day net outflow of $1.6 billion as of a prior reading — that backdrop hasn't changed.
Ethereum ETFs saw $36.7 million in net inflows the same day, with BlackRock's ETHA alone accounting for $31.7 million — institutional interest still concentrated at the top.
US markets stay closed for the next two days, so ETF flow data won't update. This four-day streak will hold as the latest read until the next trading session reveals the tug-of-war's next move.
