ETH Strong demand for Bitcoin ETFs, and significant growth in total fund size
The total net assets of spot Bitcoin ETFs have climbed to US$99.05 billion, and cumulative net inflows have reached US$54.36 billion. The number of bitcoins held in these funds 'portfolios is approximately 1.25 million, equivalent to approximately 5.9% of the maximum supply of 21 million bitcoins. ETFs hold a significant portion of the supply of bitcoin in circulation, indicating that institutional investors have an increasing weight in the market, and that new inflows of funds will remain a key factor influencing bitcoin prices.
Bitcoin ETF net inflows for seven consecutive days
On Tuesday, the U.S. spot Bitcoin ETF achieved a net inflow of US$314.37 million, indicating that investor interest is heating up again. So far, the fund recorded positive capital inflows for the seventh consecutive trading day. Total inflows reached US$3.03 billion in August, indicating a significant recovery in the ETF market recently. Strong demand for Bitcoin ETFs is also reflected in the total size of the fund. The total net assets of the spot Bitcoin ETF rose to US$99.05 billion, and the cumulative net inflow reached US$54.36 billion. The number of bitcoins held by the fund is approximately 1.25 million, which is equivalent to approximately 5.9% of the maximum supply of 21 million bitcoins.
Strong capital inflows from ETFs coincided with fluctuations in Bitcoin prices. Bitcoin briefly broke through the $80,000 mark on Tuesday and once tested $81,000 during Asian trading hours. However, as selling pressure increased, prices fell back below $80,000. The market views the $80,000 to $82,000 range as a key resistance area. If a sustained trend forms above the region, bitcoin prices may gain new upward momentum. Conversely, if profit-taking occurs in the resistance area, short-term fluctuations may be exacerbated.
Institutional demand is picking up again
The latest inflows of funds from Bitcoin ETF indicate that institutional investors 'interest in the market is recovering again. The U.S. spot Bitcoin ETF attracted a net inflow of approximately US$1.9 billion in the week from August 17 to 21, setting one of the strongest weekly performances since 2026. During the same period, the spot Ethereum ETF also attracted approximately US$697 million in inflows. The positive momentum in the ETF market is not limited to Bitcoin. The U.S. spot Ethereum ETF also attracted net inflows of approximately $179.8 million on Tuesday, extending positive inflows into a seventh trading day. The total amount of funds flowing into the Ethereum ETF recently has reached nearly US$1 billion. The strong demand for Bitcoin and Ethereum ETFs at the same time demonstrates the continued interest of institutional investors in the cryptocurrency market.
Assessment
The U.S. spot Bitcoin ETF has achieved positive capital inflows for seven consecutive trading days, which sends an important signal that institutional demand in the cryptocurrency market has increased again. A net inflow of US$3.03 billion in August and ETF assets approaching US$99 billion formed a supportive situation for Bitcoin. In the future, whether Bitcoin can break through the resistance zone of US$80,000 to US$82,000 and whether the inflow of ETF funds can continue will be key factors in determining the direction of the price.
