特朗普宣布取消对伊朗的军事打击计划，双方达成了协议框架，这在地缘政治上算是个好消息，理论上会让市场敢冒险买风险资产（比如比特币）。但奇怪的是，比特币价格没怎么动，7月31日这天，比特币现货ETF（在传统股票交易所上市、方便机构买比特币的基金）最新一日净流出2.65亿美元。恐慌贪婪指数（衡量市场情绪的指标，0代表极度恐慌，100代表极度贪婪）本周一直卡在25到28分，属于"恐慌"区间，没有随着好消息回暖。
这就是情绪和资金对不上号的地方：利好新闻落地了，钱却没跟着进来。我们在7月28日已经把BTC的立场从"谨慎看多"下调为"中性"，原因不是这条伊朗新闻，而是更早的信号：之前支撑乐观判断的ETF连续流入已经反转成流出，同时当天比特币出现了一次跌幅，这个跌幅在它自己过去30天的波动范围里算是比较大的（排在87百分位），当天还恰好有一个独立事件凑在一起（具体细节有限，不做过度解读）。
值得说明的是，7月30日ETF数据曾短暂止跌，单日转为净流入3210万美元，但整个7月的ETF资金流入正朝着近几个月里比较少见的低位走。换句话说，钱没有大规模跑光，但也没有明显回来。
这个中性判断在什么情况下会改变？如果ETF资金流出现连续多日的净流入，或者恐慌贪婪指数明显走出25-28的低位区间，那就是方向可能重新变清晰的信号；反过来，如果流出持续扩大，中性也可能进一步转向谨慎看空。
Trump announced he's canceling a planned military strike on Iran and reached an agreement on the "perimeters of a deal." That's typically the kind of headline that makes investors more willing to buy riskier assets like Bitcoin. But Bitcoin barely moved. On July 31, Bitcoin spot ETFs (funds traded on regular stock exchanges that let institutions buy Bitcoin exposure) saw a net outflow of $265 million for that single day. The Fear & Greed Index, a gauge of market mood from 0 (extreme fear) to 100 (extreme greed), has been stuck at 25-28 all week — still in "fear" territory despite the good news.
That's the disconnect: good news landed, but the money didn't follow. We had already downgraded our BTC stance from "cautiously bullish" to "neutral" on July 28 — not because of Iran, but because the ETF inflows that had been supporting our optimism had reversed into outflows, combined with a price drop that day large enough to rank in the 87th percentile of Bitcoin's own 30-day volatility range, alongside a separate event happening the same day (details are limited, so we're not reading too much into it).
Worth noting: ETF flows briefly turned positive on July 30, with a one-day net inflow of $32.1 million, but this month's overall ETF inflows are trending toward some of the lowest levels seen in recent months. Money isn't rushing out en masse, but it isn't clearly coming back either.
What would change this neutral call? Several consecutive days of ETF net inflows, or the Fear & Greed Index clearly breaking out of the 25-28 range, would suggest direction is becoming clearer. If outflows deepen instead, neutral could slide toward cautiously bearish.
