核心判断：美债收益率走高本该利空比特币这类无息资产，但资金流数据出现背离，这个背离还不足以推翻此前的谨慎看多立场。
关键证据：一、10年期美债收益率升至2007年以来最高水平，今日日报把它列为新变量，加密监管法案Clarity Act在国会遇阻也拖累情绪。二、BTC现货ETF在9月14日单日净流入1.60亿美元，结束此前连续三天的净流出。三、恐慌贪婪指数最新读69（贪婪区间），比之前的63有所回升，说明情绪并未彻底转向防守。四、BTC现价77,023美元，24小时跌0.8%，7天跌1.8%，距7天高点还差3.3%，跌幅并不剧烈。
反例/弱化条件：我们在9月10日曾把BTC立场从看多下调为谨慎看多，理由是单日大跌叠加ETF连续净流出、多空比转向空头拥挤。这次单日转为净流入的资金流数据，方向上和当时下调立场的逻辑相反，但只是一天的数据,还不构成对谨慎看多立场的推翻。
判断加固：真正的检验点是FOMC利率决议，大约28.7小时后公布（含最新经济预测摘要SEP）。决议前市场普遍进入防守姿态，中文加密社区对"加息概率90%"和"币圈牛熊三大关键日"的讨论热度明显升高，播放偏离度分别达到2.3σ和2.4σ，说明散户情绪也在紧绷。
失效条件：如果FOMC决议后ETF资金流转为连续多日净流出，同时BTC跌破距7天高点3.3%以上的幅度并伴随多头清算放大，谨慎看多立场需要下修为看空。反之若ETF净流入连续三天以上且收益率见顶回落，立场可上调。
Core call: rising Treasury yields should be bad news for a non-yielding asset like bitcoin, but the flow data just told a different story — not enough yet to overturn our cautious-bullish stance on BTC.
Evidence: the 10-year Treasury yield climbed to its highest level since 2007, flagged as a new variable in today's market brief, while the Clarity Act crypto bill stalling in Congress added to the defensive mood. Yet BTC spot ETFs posted a $160 million net inflow on September 14, ending three straight days of net outflows. The Fear & Greed Index reads 69 (Greed), up from a recent 63, meaning sentiment hasn't fully turned defensive. BTC itself trades at $77,023, down just 0.8% on the day and 1.8% over 7 days — only 3.3% below its 7-day high.
Countervailing point: we downgraded BTC from bullish to cautious-bullish on September 10, after a sharp one-day drop combined with three straight days of ETF outflows and a long/short ratio tilting crowded-short. This single day of inflows points the opposite direction of that downgrade's logic, but one day of data doesn't reverse the stance.
The real test: the FOMC rate decision (with its Summary of Economic Projections) lands in roughly 28.7 hours. Ahead of it, Mandarin-language crypto channels are buzzing — one hit 2.3 standard deviations of unusual attention discussing a 90% odds of a hike, another 2.4 standard deviations calling this week's crypto "bull-or-bear" moment.
This stance flips bearish if ETF outflows resume for multiple days alongside deeper losses from the 7-day high plus rising long liquidations; it upgrades if inflows persist beyond three days and yields roll over.
