Today, the most noteworthy thing about BTC is not whether it has risen or fallen, but that the continuous 9-day net inflow of ETF funds has suddenly been interrupted.

On September 30, the US spot BTC ETF ended its 9 consecutive trading days of capital inflow, turning into a net outflow of about $149 million in a single day. In the previous 9 days, the cumulative inflow was about $3 billion.

Why is this change worth watching?

Because BTC is still fluctuating around $84,000, and the price has not shown a significant slowdown, but the most important incremental funds have started to cool down briefly. In other words, it’s not that no one is buying in the market, but the rhythm of the funds that continuously pushed up the price earlier has changed.

So what’s more worth observing now is not simply judging bullish or bearish, but whether BTC can continue to hold its current position after the cooling of funds.

The key resistance above is between $85,000 and $85,500, where there is obvious selling pressure; below, first watch around $80,000, and further down, pay attention to the key cost support at about $77,200.

If ETF funds turn positive again and the price approaches the resistance level with increased volume, the market focus will change again; conversely, if funds continue to flow out and the price fails to break through for a long time, the divergence may further widen.

What’s truly worth watching is whether this pause in funds is just a breather or if the rhythm has really changed?
