The landscape of Bitcoin investing in the United States has undergone a significant transformation since the launch of spot Bitcoin exchange-traded funds (ETFs) in January 2024. While these financial instruments have attracted substantial capital—nearly $39 billion in net inflows—the nature of that investment is revealing a critical insight: most investors are not in it for the long haul.
According to Markus Thielen, head of research at 10x Research, approximately 56% of spot Bitcoin ETF investments are driven by short-term arbitrage strategies, leaving only about 44% tied to genuine long-term holdings. This imbalance highlights a market more focused on exploiting temporary pricing inefficiencies than embracing Bitcoin as a core portfolio asset.

Understanding the Carry Trade Strategy in Bitcoin ETFs
The dominant short-term strategy among institutional players is known as the carry trade. In this approach, hedge funds and trading firms buy Bitcoin through spot ETFs while simultaneously shorting Bitcoin futures contracts. The goal? To capture the spread—or "basis"—between the spot price and the futures price.
This strategy thrives when funding rates and basis spreads are wide, offering clear profit opportunities. However, recent market conditions have seen those spreads narrow significantly. With lower yields from arbitrage, many trading desks have slowed or halted new inflows into Bitcoin ETFs.
As Thielen noted, “Hedge funds and trading firms have stopped adding inflows to Bitcoin ETFs and are actively unwinding existing positions that no longer offer the profitable arbitrage opportunities seen a few months ago.”
This shift has direct implications for market dynamics. When large players exit their positions, it creates downward pressure on ETF flows—even if the actual impact on Bitcoin’s price remains neutral due to offsetting trades in the futures market.
Record Outflows Signal Weak Long-Term Demand
Data from Sosovalue shows that U.S. spot Bitcoin ETFs experienced over **$1.14 billion in net outflows** during the two weeks leading up to February 21—marking the largest two-week withdrawal since trading began in January 2024. This surpassed even the outflow peak observed in June 2024 when Bitcoin was near $64,000.
While such outflows often make headlines as bearish signals, Thielen emphasizes they don’t necessarily reflect a loss of faith in Bitcoin itself. Instead, they reveal a recalibration in trading strategies:
“This indicates that the actual demand for Bitcoin as a long-term asset in multi-asset portfolios is significantly smaller than media reports suggest.”
In other words, much of the early excitement around Bitcoin ETFs was fueled by sophisticated traders—not long-term believers. As those traders exit, the true level of sustainable institutional adoption becomes clearer.
Still, there are signs of growing organic interest. After the U.S. presidential election, Thielen observed an uptick in long-only buying behavior. Yet, this has been offset by declining retail trading volumes, which have contributed to compressed funding rates and reduced arbitrage appeal.
February Doldrums: Can Bitcoin Rebound?
Historically, February has been a strong month for Bitcoin, with positive price action in most years—exceptions being 2014 and 2020. But 2025 is shaping up differently.
Bitcoin has declined by 7% in February, trading around $95,640** as of late February, down slightly over the past week. Ethereum has fared worse, dropping nearly **18% over the past month** to trade at **$2,683.
Despite the dip, some analysts remain optimistic. CryptosRus pointed out that if Bitcoin can close the month above $102,500, it could still avoid becoming just the third red February in its history.
“While genuine long-term buying has picked up, the decline in retail trading volumes has led to collapsing funding rates.”
This tug-of-war between fading short-term speculation and emerging long-term conviction defines the current phase of the Bitcoin market.

Core Keywords and Market Implications
Key insights from this analysis point to several core themes shaping investor behavior:
- Bitcoin ETF inflows
- Spot Bitcoin ETF
- Arbitrage strategy
- Long-term Bitcoin investment
- Carry trade
- ETF outflows
- Institutional adoption
- Market sentiment
These keywords reflect both technical strategies and broader market psychology. The dominance of arbitrage underscores that early ETF adoption was largely tactical. True institutional embrace—where asset managers allocate to Bitcoin as a strategic holding—remains limited but may be slowly building.
Frequently Asked Questions (FAQ)
Q: What percentage of Bitcoin ETF investments are long-term?
A: According to 10x Research, only about 44% of inflows into spot Bitcoin ETFs represent long-term investment intentions.
Q: Why are traders using arbitrage with Bitcoin ETFs?
A: Traders use the carry trade strategy—buying spot BTC via ETFs and shorting futures—to profit from pricing differences between markets. It works best when basis spreads and funding rates are high.
Q: Do ETF outflows mean investors are losing confidence in Bitcoin?
A: Not necessarily. Many outflows come from traders closing hedged positions. Since selling ETF shares is often balanced by buying futures, the net impact on price can be neutral.
Q: How much money has flowed into Bitcoin ETFs since launch?
A: Since their debut in January 2024, U.S. spot Bitcoin ETFs have drawn approximately $39 billion in net inflows.
Q: Is retail interest in Bitcoin declining?
A: Recent data suggests retail trading volumes have dropped, contributing to narrower funding rates and reduced arbitrage opportunities.
Q: Can Bitcoin still recover in February?
A: Analysts believe a monthly close above $102,500 could salvage a positive outcome for February despite current losses.
The Road Ahead for Bitcoin ETFs
The story of Bitcoin ETFs so far is one of initial hype followed by market realism. While billions have poured into these products, much of that capital was never meant to stay. The real test lies ahead: whether long-term demand can grow to match the infrastructure now in place.
For investors watching from the sidelines, understanding the difference between speculative flows and true adoption is crucial. The current correction may be painful, but it also clears space for more sustainable growth.
As institutional frameworks mature and regulatory clarity improves, the balance may gradually shift toward longer-duration capital. Until then, volatility driven by strategy shifts—rather than fundamental changes—will likely persist.
