先说结果：美国6月PPI（生产者物价指数，衡量企业出厂价格的通胀指标）环比出现近一年来首次下降。这个数据周三（7月15日）公布后，比特币应声涨破6.5万美元，24小时涨2.4%。
这里有个细节值得多看一眼。7月14日之前，比特币的反弹更多是空头平仓式的——价格涨，但衍生品持仓量在缩。而这次不一样，资金费率（多空双方为持仓支付的成本）和持仓量同步走高，说明是真金白银在开新多单，而不是空头认输离场。这个区别很重要，因为前者往往是一次性反弹，后者更像是情绪开始转向。
资金面也有回暖迹象。比特币现货ETF在7月14日单日净流入1.81亿美元，结束了此前的连续流出。不过要泼盆冷水：这只是止跌后的第一天，能不能连续流入还得再看几天，一天的数字定不了趋势。
更矛盾的是，恐慌贪婪指数（衡量市场情绪的0-100指标）目前还停留在25分，属于"极度恐慌"区间，跟价格反弹明显背离。稳定币市值同步收缩，说明场外资金还在观望，没有大举跟进。
OpenClue在7月10日就已把比特币立场从中性上调为"谨慎看多"，当时的判断依据是24小时涨幅达到自身30天波动区间的87百分位，加上日本国内资金流入比特币的消息以及衍生品持仓变化。这次由PPI数据驱动的反弹方向与此前判断一致。
记住一句话：情绪指标恐慌、资金流刚回暖一天，比特币这波涨势能不能站稳，还得看后面几天ETF资金和杠杆数据能不能持续印证。
Here's what happened: June's Producer Price Index (PPI, a measure of wholesale-level inflation) fell month-over-month for the first time in about a year. The data dropped Wednesday, July 15, and Bitcoin jumped past $65,000 within hours, up 2.4% on the day.
One detail worth noticing: before July 14, Bitcoin's bounces looked like short-covering — price up, but derivatives open interest shrinking. This time it's different. Funding rates (the fee longs and shorts pay each other to hold positions) and open interest both rose together, meaning traders are opening fresh long positions, not just shorts giving up. That distinction matters — one is usually a one-off pop, the other looks more like a real shift in appetite.
There's also a funding signal. Bitcoin spot ETFs took in a net $181 million on July 14 alone, breaking a streak of outflows. But don't get ahead of it — this is a single day right after the bleeding stopped. Whether inflows continue for a few more days is what actually confirms a trend, not one number.
Here's the odd part: the Fear & Greed Index (a 0-100 sentiment gauge) still sits at 25, deep in "Extreme Fear" territory — a clear disconnect from the price rally. Stablecoin market cap also shrank in parallel, suggesting sidelined cash hasn't rushed back in yet.
OpenClue had already shifted its Bitcoin stance from neutral to cautiously bullish on July 10, based on a 24-hour move that ranked in the 87th percentile of its own 30-day volatility range, plus reports of Japanese domestic capital flowing into Bitcoin and shifting derivatives positioning. This PPI-driven rally lines up with that earlier call.
Bottom line: sentiment is still fearful and the ETF inflow is only one day old — whether this rally holds depends on whether fund flows and leverage data keep confirming it in the days ahead.
