The narrative around institutional adoption of Bitcoin has long been shaped by headlines suggesting a flood of traditional finance into spot Bitcoin ETFs. However, new analysis from 10x Research paints a more nuanced picture — one where only a fraction of inflows reflect genuine long-term conviction.
Markus Thielen, founder of 10x Research and former Head of Research & Strategy at Matrixport, recently revealed that just 44% of net inflows into U.S. spot Bitcoin ETFs can be attributed to long-term holders, often referred to as "HODLers" in the crypto community. This equates to approximately $17.5 billion in assets held with a buy-and-hold strategy.

The remaining 56%, according to Thielen, appears to be driven primarily by arbitrage strategies. These involve sophisticated traders capitalizing on pricing discrepancies between spot ETFs and Bitcoin futures markets. In many cases, short positions in futures offset the spot ETF inflows, meaning the net exposure to Bitcoin price appreciation is effectively neutralized.
Challenging the Institutional Adoption Narrative
Despite widespread media coverage suggesting that institutions are rushing into Bitcoin through ETFs, Thielen argues this perception is exaggerated.
“Rather than reflecting broad-based institutional adoption, the buying and selling of Bitcoin ETFs is primarily driven by funding rates (basis rate opportunities), with many investors focusing on short-term arbitrage rather than long-term capital appreciation.”
This insight challenges the bullish narrative that Wall Street’s embrace of Bitcoin is accelerating at an overwhelming pace. Instead, much of the trading volume may stem from tactical, short-term plays rather than strategic portfolio allocation.
Still, there are signs of growing genuine demand. Thielen notes a marked increase in long-only buying — investments not hedged with futures — following former President Donald Trump’s victory in the 2024 election. The pro-crypto policy stance associated with his campaign appears to have reignited interest among true believers in digital assets.
U.S. Spot Bitcoin ETF Inflows: A Closer Look
As of last Friday’s market close, total net inflows into U.S. spot Bitcoin ETFs since their January 2024 launch reached $39.573 billion, according to data from Farside Investors.
Leading the pack is BlackRock’s iShares Bitcoin Trust (IBIT), which has attracted $40.879 billion in net inflows — surpassing the total market sum due to outflows at other funds.
Other major players have also seen solid traction:
- Fidelity Wise Origin Bitcoin Fund (FBTC): $12.332 billion
- ARK 21Shares Bitcoin ETF (ARKB): $4.7 billion
- Bitwise Bitcoin ETF (BITB): $2.8 billion
- WisdomTree Bitcoin Fund (BTCW): $250 million
However, Grayscale Bitcoin Trust (GBTC) continues to drag down overall figures with $22.106 billion in net outflows since its conversion from a private trust to a publicly traded spot ETF. This outflow reflects long-standing investor dissatisfaction with Grayscale’s premium pricing pre-ETF approval and a shift toward lower-fee alternatives post-launch.

What’s Driving Short-Term vs. Long-Term Investment?
Understanding the split between arbitrage-driven flows and HODL behavior is crucial for assessing true market health.
Arbitrageurs exploit the difference between spot ETF prices and futures contracts. When futures trade at a premium (a condition known as contango), traders buy spot ETF shares and short futures to lock in risk-free returns. This activity inflates ETF asset totals without increasing actual long exposure to Bitcoin.
In contrast, long-term holders believe in Bitcoin’s fundamental value proposition — scarcity, decentralization, and potential as digital gold. Their investments remain unhedged and reflect confidence in sustained price appreciation over years.
Thielen’s findings suggest that while speculative mechanics dominate current flows, underlying demand is evolving. The post-election uptick in unhedged buying could signal a shift toward more organic adoption.
Bitcoin Price Outlook: Key Levels to Watch
Ryan Lee, Chief Analyst at Bitget Research, shared his short-term outlook for Bitcoin with Blockzeit, projecting a trading range between $92,000 and $105,000 for the coming week.
Critical technical levels include:
- Resistance at $100,000: A breakout above this psychological barrier could trigger renewed bullish momentum.
- **Support at $94,000**: Failure to hold this level may lead to a pullback toward $92,000.
Market sentiment will likely hinge on macroeconomic data, regulatory developments, and on-chain activity. Institutional participation — whether speculative or genuine — will continue to influence volatility.
Ethereum’s Path to $3,000
While Bitcoin dominates ETF conversations, Ethereum remains in focus due to its upcoming Pectra upgrade. Expected to enhance scalability and wallet functionality, Pectra could boost investor confidence.
Lee forecasts ETH to trade between $2,600 and $2,900 in the near term. A successful test of the $2,900 resistance could pave the way for a move toward **$3,000**, especially if the upgrade is implemented smoothly and met with positive market reaction.
Frequently Asked Questions (FAQ)
Q: What percentage of Bitcoin ETFs are held by long-term investors?
A: According to 10x Research, approximately 44% of net inflows into U.S. spot Bitcoin ETFs are attributed to long-term holders (HODLers), representing about $17.5 billion in assets.
Q: Why is GBTC showing negative inflows?
A: Grayscale Bitcoin Trust (GBTC) has experienced significant outflows — over $22 billion — since becoming a spot ETF due to high fees compared to competitors like BlackRock and Fidelity, prompting investors to migrate to lower-cost options.
Q: Are institutional investors really adopting Bitcoin en masse?
A: Not yet. While institutional interest exists, much of the ETF activity is driven by arbitrage rather than long-term investment. True institutional adoption remains limited but shows signs of growth post-2024 election.
Q: What drives Bitcoin ETF arbitrage?
A: Arbitrage occurs when traders exploit price differences between spot ETFs and futures contracts. They buy ETF shares and short futures to capture risk-free profits when futures trade at a premium (positive basis).
Q: How might political events affect crypto markets?
A: Pro-crypto policies or candidates — such as Donald Trump’s 2024 campaign — can boost market sentiment and increase long-only investment in Bitcoin, reducing reliance on hedged strategies.
Q: What is the significance of the Pectra upgrade for Ethereum?
A: The Pectra upgrade aims to improve Ethereum’s scalability and user experience, particularly through account abstraction. A successful rollout could strengthen ETH’s position and drive price momentum toward $3,000.
