$150 Billion Later: The Truth About Bitcoin ETFs and Who’s Buying

August 16, 2025 | $117,000+ | $2.35T

In this week’s episode, the team is joined by James Seyffart, from Bloomberg Intelligence, and one of the most trusted voices tracking institutional Bitcoin adoption. 

Seyffart shares insights from covering Bitcoin ETFs pre- and post-approval, what he’s seeing in advisor flows, how traditional finance is adapting (or resisting), and why ETF demand has blown past even the most bullish expectations.

The group explores the psychology of Wall Street’s Bitcoin aversion, the role of ETF wrappers in overcoming institutional friction, and how this cycle could be shaped by the slow unlock of advisor and banking distribution pipes.

ETF Demand Has Surpassed Expectations

  • James confirms that spot Bitcoin ETFs are the most successful ETF launch in history by every metric: assets, flows, and volume.

  • Over $55 billion in net inflows since launch, with total AUM now exceeding $150 billion across spot products.

  • More than 1.3 million BTC (roughly 6.6% of total supply) is now held in ETFs, with expectations for continued growth.

  • Institutional demand has largely come from hedge funds (via basis trades) and RIAs, who are slowly overcoming platform restrictions.

  • Advisor allocations are increasing, but many wealth platforms still limit access or require manual client requests—highlighting how early this trend still is.

  • The team emphasizes that ETF demand is no longer just a retail phenomenon—it’s now a major institutional access point.

Breaking Through TradFi Resistance

  • Seyffart outlines the main reasons traditional finance professionals struggle with Bitcoin:

    • Lack of cash flows (conflicts with CFA-style valuation frameworks).

    • Association with fraud and broader crypto scandals.

    • Ego and psychological aversion to an investment they missed.

  • Larry Fink’s turnaround was highlighted as a major unlock—he moved from calling Bitcoin a tool for money laundering to endorsing it as a hedge against currency debasement.

  • The BlackRock endorsement gave advisors permission to explore Bitcoin seriously, acting as “air cover” for hesitant allocators.

  • Even so, firms like Vanguard are still blocking access, reflecting deep cultural resistance rooted in old paradigms.

Bitcoin and Gold: Macro Assets Reasserting Themselves

  • Both gold and bitcoin are outperforming other asset classes in 2025; #1 and #2 YTD performance, respectively, highlighting their return to prominence as macro hedges.

  • Seyffart views gold and Bitcoin as complementary assets, not competitors. Bitcoin is the higher volatility, ‘call option’ on store of value assets.

  • He rejects the idea of imminent dollar collapse, but sees structural debasement (2–4% annually) as a long-term driver of sound money demand.

  • The conversation highlights how younger generations are structurally disadvantaged, priced out of homeownership, seeing real earnings lag asset inflation, and more open to Bitcoin as a response.

  • Institutions that ignore gold or Bitcoin entirely are becoming increasingly disconnected from real macro shifts.

Custody, Risk, and the Coinbase Question

  • Coinbase now custodies the vast majority of ETF assets, with no real institutional diversification yet implemented.

  • Seyffart views Coinbase as a de facto SIFI (Systemically Important Financial Institution) for the Bitcoin ETF market.

  • The team raises concerns about counterparty concentration risk and parallels to legacy banking crises.

  • A new generation of allocators may push for more secure, redundant custody models as awareness grows.

  • Onramp’s multi-institution custody model is mentioned as a solution for eliminating single points of failure.

Portfolio Construction and the New Default

  • ‘Bitcoin-savvy’ advisors continue recommending 1–5% allocations to clients, while personally holding 30% or more.

  • The conversation highlights a major disconnect between public recommendations and actual portfolio behavior in the space.

  • Seyffart argues that zero is no longer the default, Bitcoin is a multi-trillion-dollar asset, and holding zero is now an active underweight.

  • The Harvard endowment’s 0.2% position reflects a market-cap-weighted neutral allocation, providing cover for other institutions to follow suit.

  • Most institutions are still in the early innings of their Bitcoin journey, the real demand unlock lies ahead.

  • Sovereign buyers, RIA access, lending markets, and structured treasury vehicles could all accelerate the next leg of adoption.
