Bitcoin spot ETFs recorded $433 million in net inflows on September 18, reversing earlier selling pressure from midweek outflows of approximately $746 million.
Fidelity's Wise Origin Bitcoin Fund (FBTC) led the inflows with $310.72 million, representing about 72% of the day's total. BlackRock's IBIT added $108 million, with the two funds capturing approximately 97% of net additions. Other spot Bitcoin products accounted for the remaining share.
ETF Assets and Market Concentration
Total U.S. spot Bitcoin ETF assets stood at $102.53 billion, equal to roughly 6.29% of Bitcoin's overall market value. Fidelity's FBTC has gathered approximately $10.36 billion in net inflows since its January 2024 launch, placing it behind BlackRock's IBIT among U.S. spot Bitcoin ETFs by total capital attracted.
The September 18 inflow marked a significant concentration of demand, with two funds capturing the vast majority of new capital entering spot Bitcoin ETF products during the session.
Bitcoin Price and Technical Levels
Bitcoin traded near $81,330 as the daily RSI reached 64.48, above its signal average of 57.25 but below the 70 level often associated with overbought conditions. Other technical indicators showed bullish positioning, including a bullish Supertrend and positive Aroon spread.
Liquidity data identified a dense cluster of liquidations between $81,800 and $82,000, with additional liquidation zones near $82,500 to $83,000 and around $84,000.
Support and Resistance Levels
Downside liquidity concentrations appeared near $80,000 and $79,400, with a broader support zone between $78,500 and $79,000. The lower Bollinger Band sat near $74,948, with leveraged liquidation positions concentrated between $75,000 and $76,000.
Factors Affecting Market Direction
Bitcoin ETF inflows provide one demand signal, but daily flows do not guarantee continued price gains. Market movements can be influenced by fund activity, derivatives positioning, macroeconomic policy, and profit-taking.
Macro developments included a 25 basis point rate increase by the Federal Reserve and a rate increase by the Bank of Japan to 1.25%. The U.S. Senate rejected the CLARITY Act, delaying federal cryptocurrency market structure legislation.
