Bitcoin once fell into the $76,000 range

In terms of prices, data from CoinCodex shows that BTC was trading at around $77,095 earlier on September 11, with a 24-hour decline of 1.76%. During that period, Bitcoin briefly reached $78,000, but then selling pressure increased, causing it to fall back down to the mid-$76,000 range at night.
Thereafter, the price returned above $77,000, but it was still lower than the previous level. The outflow of funds coincided with the decline in price, reflecting a weakening of institutional buying in recent trading days.
ETF Capital flow remains a short-term observation indicator
Judging from its recent performance, the flow of funds for ETF remains an important indicator to observe whether Bitcoin can stabilize around $77,000. If redemptions continue to increase, the market may face further downward pressure; if the outflow of funds slows down, price fluctuations may also ease accordingly.
In this round of adjustments, what is more noteworthy is the general pressure on large funds, rather than abnormal fluctuations in individual products. This indicates that the cooling down of institutional allocation demand is having a more direct impact on Bitcoin's short-term performance.
