Spot BTC and ETH ETFs see their best week since October 2025 For the week of August 17-21, U.S.-registered spot Bitcoin and Ether ETFs attracted $2.61 billion, the best weekly inflow since October 2025. Bitcoin funds received $1.92 billion (73% of the total), while Ethereum ETFs saw inflows of $697.47 million. On August 21 alone, spot Bitcoin ETFs attracted $307 million, marking five consecutive positive trading sessions. BlackRock's iShares Bitcoin Trust (IBIT) led with $239 million, followed by Fidelity's Wise Origin Bitcoin Fund (FBTC) with $30.19 million. The total net assets of all U.S. spot Bitcoin ETFs reached $96.07 billion, representing 6.17% of Bitcoin's market cap. Spot Ethereum ETFs attracted $185 million on August 21, led by the iShares Ethereum Trust ETF (ETHA) with $151 million in inflows. The total net assets for all U.S. spot Ethereum ETFs stood at $14.30 billion.

After a prolonged lull, the crypto market exploded last week, with Bitcoin surging over 26% to nearly $79,500, its biggest weekly gain since March 2023. This rally, fueled by a US long-term bond buyback program and pro-crypto signals from Trump, confirmed key market patterns: crypto's short-term direction is increasingly tied to US policy, Bitcoin spot ETFs act as a leading indicator, and Bitcoin's gains trigger a clear capital rotation into altcoins. Ethereum outperformed Bitcoin, rising nearly 30% due to strong ETF inflows and shrinking exchange supply. Among altcoins, the top weekly gainers were ENA (~101%), PUMP (~88-99%), STX (~82-94%), TRUMP (~79-91%), and ZEC (~75%). Zcash notably hit a new all-time high. Meme coins like "牛来" and BOME also saw explosive gains, demonstrating the sector's high elasticity. The rally outlined a clear path: Bitcoin sets the stage, major coins follow, and altcoins/Meme coins deliver the most dramatic performances, reflecting the market's shift from caution to exuberance.

US spot Bitcoin ETF inflows surged to $1.92 billion for the week ending Friday, their strongest week since October 2025, according to SoSoValue data. This resurgence coincided with Bitcoin's price jumping over 20%, briefly surpassing $79,000. Spot Ether ETFs also saw about $700 million in inflows. Despite the strong week, US spot Bitcoin ETFs remain in net outflows of roughly $2.91 billion for 2026, though August has brought $2.38 billion in net inflows, making it the year's best month so far. BlackRock's iShares Bitcoin Trust (IBIT) led last week's inflows, attracting approximately $1.33 billion over five consecutive days, with analysts noting a bullish pattern in its daily flow data.

Bitcoin surged past $79,000, with analysts suggesting it may now be in a consolidation phase. According to Bitfire Research, geopolitical risks (like tensions in the Strait of Hormuz), U.S. long-term Treasury yields nearing ~5.337%, and evolving crypto regulations have collectively influenced the recent rally. The firm noted that clarifying regulations could boost investor confidence. Approximately $1.92 billion flowed into U.S. spot Bitcoin ETFs recently, supported by large short liquidations. Analysts conclude that continued capital inflow is key for the rally to transition into a sustained mid-term uptrend. Market attention is now focused on the Jackson Hole symposium and the first speech there by new Fed Chair Kevin Warsh. Investors await clues on future interest rate policy, as persistent inflation from oil prices and high bond yields has created uncertainty about potential rate cuts. Warsh's comments are expected to set a new direction for the crypto market. Other major cryptocurrencies like XRP, Ethereum, Dogecoin, and Solana also posted significant weekly gains.

On August 24, a wallet identified as 'bowen1476' opened its 15th Bitcoin short position in five days, this time for 300 BTC (worth ~$23.13M) with 40x leverage. This move follows 14 consecutive losing shorts over the same period, resulting in total losses of $4.56 million. The new position was opened around $77,500, betting against a significant BTC rally partly fueled by the U.S. Treasury doubling its long-term bond buyback operations and former President Trump's call for clearer crypto regulations. This trader has a history of high-leverage, high-volume shorts; a single 700 BTC short in May wiped out $1.71M in profits. The recent market surge liquidated over 172,000 short positions in 24 hours, causing ~$3B in bearish losses. The success of this 15th attempt hinges on whether Bitcoin's upward momentum continues.
