Bitcoin ETFs Pull $332.7M in a Day as Ethereum Sees $135M Outflows — Rotation Back into BTC?

Spot bitcoin exchange-traded funds (ETFs) roared back into the spotlight on Tuesday, attracting $332.7 million in net inflows, even as Ethereum funds posted sharp ￰3￱ move suggests a potential rotation back to Bitcoin after Ethereum dominated ETF flows throughout ￰4￱ to SoSoValue , Fidelity’s FBTC led the charge with $132.7 million in inflows, followed by BlackRock’s IBIT at $72.8 ￰5￱ issuers, including Grayscale, Ark & 21Shares, Bitwise, VanEck, and Invesco, also logged gains.) has hit $10 billion in assets, now the third-fastest ETF to reach this mark, trailing only BlackRock and Fidelity’s Bitcoin ETFs. #EthereumETF #BlackRock ￰0￱ — ￰6￱ (@cryptonews) July 24, 2025 The price action reinforced that ￰7￱ notched a new all-time high of $4,953.73 in August, and public company holdings of ETH swelled dramatically. 71 companies disclosed a combined $119.68 billion in Ethereum by August 31st, up from 67 firms with $98.97 billion the prior month.

Bitcoin, by contrast, saw outflows and lagged in performance despite maintaining a far larger total ETF inflow base of $54.24 billion ￰8￱ September tells a different story. Historically, Ethereum has stumbled during the month: in September 2024, ETH ETFs saw $46.54 million in outflows, registering redemptions in three out of four ￰9￱ ETFs, meanwhile, posted a $1.26 billion inflow over the same period, benefiting from risk-averse positioning as markets cooled. What’s Fueling the Rotation from Ethereum to Bitcoin? Market watchers suggest this September may again favor Bitcoin.

Historically, September has been a “cool-down” month for crypto, with ETH often underperforming due to weaker seasonal flows and lower risk appetite. Bitcoin, seen as the safer benchmark asset, typically regains inflows when volatility ￰10￱ forces are also at ￰11￱ global central banks signaling caution and bond yields holding firm, investors appear to be trimming higher-risk ETH exposure in favor of Bitcoin, still viewed as the digital reserve asset of ￰12￱ derivatives market shows the ￰13￱ the past 24 hours, Ethereum futures saw $1.22 billion in outflows, nearly double Bitcoin’s $646.7 million in outflows, according to Coinglass . Also, Bitcoin treasuries remain a magnet for institutional ￰14￱ of Sept. 1, weekly bitcoin net inflows totaled 3,102 BTC (about $335.8 million), with Michael Saylor’s MicroStrategy adding 4,048 BTC worth $449 million on Sept. 2 ￰15￱ Saylor’s Strategy Acquires 4,048 BTC bought for $449.3M at an avg price of $110,981/BTC. $MSTR #Strategy ￰1￱ — ￰16￱ (@cryptonews) September 2, 2025 By contrast, Ethereum treasuries have lagged, with fewer corporate balance sheets disclosing significant ETH allocations despite August’s record price ￰17￱ gap shows a key reason for the rotation: while ETH may offer yield and programmability, Bitcoin continues to dominate as the go-to institutional treasury ￰18￱ hunt for yield is exactly where the danger lies, according to Sharplink Gaming co-CEO Joseph ￰19￱ on Bankless , Chalom warned that companies piling into Ether to squeeze out extra returns could expose themselves to cascading risks if markets ￰20￱ Ethereum staking entry queue has surged to its highest level in nearly two years, reaching 860,369 ETH, worth approximately $3.7 billion. #Ethereum #Staking ￰2￱ — ￰21￱ (@cryptonews) September 3, 2025 “There will be people just like in traditional finance who want that last 100 basis points of yield and think it’s riskless,” Chalom said, noting that double-digit ETH yields often carry credit, counterparty, duration, and smart contract ￰22￱ greater concern, he added, is that firms already behind the curve may double down imprudently in an attempt to catch up.

“The sector could be tainted by people that do imprudent things—whether in how they raise capital or in the kind of yield strategies they chase with their ETH holdings,” he ￰23￱ of late Tuesday, Bitcoin rose 0.55% to $110,943, while Ethereum slipped 1% to $4,327. Whether this marks the start of a sustained September rotation back into Bitcoin or just a short-term rebalancing remains the key question hanging over crypto markets.
