周五(8月21日)那天，某个ETF交易台大概又刷新了一下流入数据：单日3.08亿美元进比特币现货ETF，这是连续第5天净流入了，14天累计流进22.3亿美元。同一天，恐慌贪婪指数爬到73，一周里最高。
这事儿为什么值得说道说道。昨天日报里提过一个别扭的现象——钱在进，价却在跌，资金和价格对不上号。今天这个背离解开了：比特币现价7.9万美元，24小时涨2.6%，7天涨24.8%，还在7日高点附近晃悠。链上数据也显示，比特币和以太坊过去一周持续从交易所流出，说明有人在囤，不是短炒。以太坊ETF也是连续7天净流入了。
我们8月20日就把比特币的立场从中性调成了看多，理由不是情绪，是当时那波涨势本身很极端——30天波动率排在97百分位，突破了六周的箱体，单日暴涨10.6%，同时伴随着30亿美元规模的空头爆仓和ETF单日流入创近月新高，这几件事凑在一起不像是纯情绪推动。现在这连续5天的净流入，算是把当时那个判断往前又推了一步——资金没有一次性跑掉,而是持续在进。
但别急着庆祝。美股今天开盘,过去一周纳斯达克和标普其实是跌的，加密这波反弹到目前为止，宏观面还没跟上来确认。钱是真进了，但故事还没写完。
Friday's ETF flow number landed at $308 million into spot Bitcoin funds — the fifth straight day of net inflows, bringing the 14-day cumulative total to $2.23 billion. Same day, the Fear & Greed Index climbed to 73, the highest reading in a week.
Here's why it matters. Yesterday's brief flagged an awkward mismatch: money flowing in while price kept falling. That gap has now closed. Bitcoin sits at $79,195, up 2.6% in 24 hours and 24.8% over seven days, still hovering near its weekly high. On-chain data shows both BTC and ETH have been steadily leaving exchanges all week — a sign of accumulation, not quick flipping. Ether ETFs are on their own seven-day inflow streak.
We shifted our Bitcoin stance from neutral to bullish back on August 20, not on vibes but on a genuinely extreme setup: volatility sitting in the 97th percentile of the past 30 days, a breakout from a six-week range, a 10.6% single-day surge, alongside $3 billion in short liquidations and the strongest single-day ETF inflow in recent months. That combination looked like real, independent catalysts stacking up rather than pure sentiment. Five more days of consistent inflows since then adds continuity to that call — the money hasn't been a one-off.
Don't get ahead of yourselves though. U.S. stocks reopen today after a week where the Nasdaq and S&P were both sliding. Crypto's bounce hasn't gotten macro confirmation yet. The cash is real. The story isn't finished.
