7月30日那天，比特币现货ETF的资金流终于止住了跌势，净流入3210万美元，不少人以为拐点到了。结果没撑住一天，7月31日就又转成净流出2.65亿美元。OpenClue的日报体系一直在盯这条曲线，判断是：本月ETF资金流入正朝着历史最小月度纪录的方向走。
情绪面同样没好起来。恐慌贪婪指数最新读数28，还卡在"恐慌"区间。今天（8月3日）美股正常开市，但加密市场跟股市走的不是一个节奏——美股照常交易，比特币却还在自己的低迷里打转。
更值得留意的是衍生品市场的一个细节。8月3日的日报注意到，未平仓合约在上升，但资金费率却在下降。这个组合通常意味着有人在主动开空单押注继续下跌，而不是简单的杠杆多头爆仓清洗——不过日报也把这归为次要观察信号之一，并不是唯一或已确定的下跌导火索。
同一时间，交易所资金流向出现了分化：比特币近一周是净流入交易所，通常被解读为潜在抛压；以太坊却相反，币在往外流，走向冷钱包，更像是囤币而非要卖。同一个市场，两种币走出两种故事，这种背离本身，可能才是接下来几天最值得盯的东西。
On July 30, Bitcoin spot ETFs briefly snapped their losing streak with a net inflow of $32.1 million. It didn't last a day. By July 31, flows flipped back to a net outflow of $265 million. OpenClue's daily tracking now reads this month's ETF inflow trend as heading toward its smallest monthly total on record.
Sentiment hasn't budged either — the Fear & Greed Index sits at 28, still in "Fear" territory. U.S. stock markets opened normally today (August 3), but crypto isn't moving in sync with equities this time.
A quieter but notable signal comes from derivatives. Monday's daily brief flagged open interest rising while funding rates fell — a combination that often points to fresh short positions being opened, rather than simple long liquidations. The brief treats this as one secondary signal among several, not a confirmed trigger for the downside.
Meanwhile exchange flows are splitting in opposite directions: Bitcoin saw net inflows to exchanges over the past week, typically read as potential sell pressure, while Ethereum saw net outflows toward cold storage — more consistent with holding than selling. Same market, two very different stories playing out at once.
