BTC Breaks $120K as Bitcoin ETFs Hit $5B Trading Volume
Bitcoin ETFs are once again in the spotlight after trading volume in U.S. spot Bitcoin exchange-traded funds (ETFs) surpassed $5 billion on Oct. 1, coinciding with Bitcoin breaking through the $120,000 mark.
The milestone comes as institutional investors poured fresh capital into the market, helping Bitcoin post a 10% weekly gain from late September lows near $109,000.
Institutional Inflows Drive Rally
Spot Bitcoin ETFs saw $676 million in net inflows on Oct. 1, according to market data.
- BlackRock’s iShares Bitcoin Trust (IBIT) led the charge, attracting $405 million in inflows.
- Fidelity made a significant move as well, acquiring 1,570 BTC valued at $179 million in a single day.

The broader Bitcoin market also surged, with daily trading volume across all exchanges exceeding $50 billion as Bitcoin climbed as high as $120,500.
BlackRock’s IBIT now holds 773,000 Bitcoin, worth roughly $93 billion, representing 3.88% of total Bitcoin supply — firmly cementing its status as the largest institutional custodian of Bitcoin.
Bitcoin ETFs Grow to $155.89 Billion
Since their January 2024 launch, spot Bitcoin ETFs have accumulated $58.44 billion in net inflows, pushing total assets under management to $155.89 billion.
That figure represents 6.66% of Bitcoin’s total market capitalization, underscoring the accelerating institutional adoption of Bitcoin through regulated ETF structures.
Vanguard Reconsiders Stance on Bitcoin ETFs
One of the most surprising developments came from Vanguard, the world’s second-largest asset manager with $11 trillion under management.
Long considered a crypto skeptic, Vanguard recently removed a blog post dismissing Bitcoin’s value and is now evaluating whether to allow its 50 million clients to invest in Bitcoin and Ethereum ETFs.
The potential shift comes under new CEO Salim Ramji, who previously worked at BlackRock and has signaled openness to digital assets. Vanguard currently finds itself in a delicate position: while critical of Bitcoin, it remains one of the largest holders of Strategy stock (MSTR), a company deeply tied to Bitcoin exposure.
A Vanguard spokesperson told Bloomberg that the firm “continuously evaluates our brokerage offer, investor preferences, and the evolving regulatory environment.†While no official decision has been made, even a 1% adoption rate among Vanguard clients would bring 500,000 new Bitcoin ETF investors.
BlackRock Expands With Premium Income Bitcoin ETF
In a further sign of market maturity, BlackRock filed for a new Bitcoin Premium Income ETF. The fund will operate as a covered-call strategy, offering yield on Bitcoin holdings, and is registered under the name iShares Bitcoin Premium ETF.
The product is designed to build on the success of IBIT, which has already grown into an $87 billion fund.
BlackRock’s crypto lineup is proving highly lucrative, generating $260 million in annual revenue, including $218 million from Bitcoin ETFs and $42 million from Ethereum ETFs. With over $101 billion in digital assets under custody, BlackRock remains the dominant player in the institutional crypto space.
Last week, its Ethereum ETF recorded $512 million in net inflows, further cementing digital assets as one of the fastest-growing categories for the firm.
Technical Outlook: Bitcoin Eyes $128K
On the technical front, Bitcoin is showing signs of continued bullish momentum. Analysts note a repeating pattern of consolidation and breakout phases that has defined Bitcoin’s uptrend since 2023.
Currently priced around $120,376, Bitcoin has broken through resistance at $110,000 and successfully retested that level as support. This sets up the potential for an advance toward the $128,000–$135,000 range.
Key support sits at $110,000–$112,000. A failure to hold this zone could see Bitcoin retrace toward $103,000–$105,000. On the upside, a decisive break above $128,000 could open the path to $135,000–$140,000, with upper resistance projected as high as $173,000.
The Bigger Picture
With spot Bitcoin ETFs surpassing $5 billion in daily trading volume, Bitcoin breaking $120,000, and institutional adoption accelerating, the role of ETFs in shaping Bitcoin’s market structure is undeniable.
As major players like Vanguard reconsider their stance and BlackRock innovates with new ETF strategies, the next phase of Bitcoin’s growth could be driven less by retail speculation and more by institutional flows — potentially pushing Bitcoin into uncharted price territory.
