Exchange-traded funds have changed how capital reaches crypto markets and how traders find prices. The arrival of spot Bitcoin ETFs opened regulated on-ramps. At the same time, a meaningful share of mined Bitcoin sits outside active markets. This report explains how ETFs alter market structure and why the effective Bitcoin float falls well short of 21 million coins.

ETFs Expand Access to Bitcoin Markets

ETFs let investors buy Bitcoin exposure through standard brokerage accounts. This structure removed custody and private-key management for many buyers. Investors then moved capital into familiar products listed on major exchanges.

Chainalysis observed that spot-ETFs drove trading volumes into the billions per day within months of launch.

Regulators and issuers created prospectuses, oversight, and audit requirements for these funds. The SEC approved multiple spot Bitcoin listings in January 2024.

SEC Chair Gary Gensler noted the agency approved the listing and trading of a number of spot Bitcoin exchange-traded products, marking a procedural turning point for market access.

ETFs Change Liquidity and Price Formation

Authorized participants now exchange ETF shares for underlying Bitcoin. This creation/redemption mechanism links ETF flows with spot markets. Market-making firms increased activity to support arbitrage and large block trades.

Major liquidity providers helped narrow spreads and improve execution quality for institutional trades.

At the same time, ETF flows influence daily price discovery. Large inflows can bid prices upward quickly. Conversely, sustained outflows can remove demand and pressure prices. Market observers now monitor ETF net flows as part of standard price analysis. Chainalysis documented large early inflows that matched high daily trading volumes.

ETFs Drive Institutional Bitcoin Adoption

Asset managers deployed regulated fund structures that appeal to pensions, endowments, and wealth managers. Major issuers launched competing ETFs. Institutions then allocated capital through those products rather than directly holding private keys. This shift created a concentrated pool of institutional demand routed into ETFs. Evidence shows certain ETFs grew to tens of billions in assets in under a year.

Wealth managers and broker-dealers scaled their offering and distribution channels. The result moved sizable blocks of Bitcoin into custodial arrangements under fund sponsors and their partners. This concentration affects how much supply remains available for active trading.

Custody Links Crypto to Traditional Finance

ETF issuers contracted regulated custodians, auditors, and clearing agents. Traditional financial infrastructure now supports large Bitcoin holdings. Institutional custodians apply governance, insurance, and reporting standards that differ from self-custody. These arrangements increase investor confidence and also reduce turnover in those holdings.

Market participants link ETF strategies to futures and options markets. Traders hedge ETF exposure via derivatives, which increases activity on exchanges such as the CME.

The cross-market linkages changed intraday flow patterns and reduced fragmentation between venues.

Why is a substantial portion of Bitcoin effectively unavailable

On-chain analysis shows a nontrivial share of mined Bitcoin never moves again. Independent research finds that between three and four million BTC likely remain permanently inaccessible.

Analysts attribute these losses to forgotten keys, discarded hardware, and unrecoverable custodial accounts. These coins still exist on the ledger, but holders cannot move them.

Some of the largest examples include early-era addresses that remain dormant. Those coins reduce the usable supply relative to the 21 million cap. As a result, market participants must base liquidity assessments on the effective float, not the theoretical total.

Long-Term Holding Shrinks Tradable Supply

Beyond permanently lost coins, many holders keep Bitcoin offline for long periods. Long-term holders now control a large portion of the circulating supply. Funds, corporate treasuries, and strategic reserves hold coins for extended horizons.

Analysts estimate U.S. spot ETFs and institutional treasuries together hold over one million BTC, which removes these coins from daily trading pools.

On-chain metrics show older UTXOs grow as new issuance slows after halving events. When holders prefer storage over trading, available liquidity declines. That scarcity amplifies price response to marginal demand.

What This Means for Bitcoin Markets

Taken together, ETF accumulation, institutional treasuries, and lost coins lower the effective supply. Analysts place the usable circulating supply below the raw mined total. Markets now respond to changes in institutional flows more than in prior cycles. This structural change raises the sensitivity of price to net inflows and outflows.

Regulatory clarity and custody standards helped mainstream ETF adoption. Those same structures increased the proportion of Bitcoin held in long-term, low-turnover accounts. The market, therefore, shows signs of maturing.

Yet price remains sensitive to large fund flows and macro events. Observers should monitor ETF flows, custody reports, and on-chain dormancy metrics to assess liquidity and risk going forward.

Key takeaways:

• Ether price struggled as investors pulled $225 million from the spot ETFs, and Ethereum staking rewards underperformed compared to stablecoin yields.

• Recent Ethereum network upgrades and plans for improved wallet security are positives, but fail to kickstart demand for Ether.

Ether (ETH) price has repeatedly failed to sustain levels above $2,100 over the past month, gradually eroding traders’ confidence in the altcoin. Even with a 7% rise between Monday and Tuesday, ETH derivatives metrics suggest a lack of interest in leveraged bullish positions, potentially signaling that bears remain in control.

ETH perpetual futures dipped into negative territory on Tuesday, signaling increased demand for short (bearish) positions. More importantly, this metric has remained below the neutral 6% to 12% range for the past month. Part of this investor disappointment stems from a 54% price decline over six months, even though cooling onchain activity has also played a significant role.

Weekly base layer fees on the Ethereum network averaged $2.3 million over the past month, down from an $8 million peak in early February. While 7-day transaction counts stabilized near 14 million, the current industry focus on layer-2 rollup scalability has so far failed to generate fresh demand for native Ether.

Contrary to perpetual futures markets, the ETH options risk gauge hovered near the neutral -6% to +6% range on Tuesday. Put (sell) options traded at a 7% premium relative to call (buy) instruments, suggesting confidence is slowly returning among Ether bulls. Furthermore, no competitor has yet challenged Ethereum’s $56 billion in total value locked (TVL).

Ether exchange-traded funds (ETFs) saw $225 million in net outflows between Thursday and Monday, reversing the $169 million in inflows seen on Wednesday. This metric serves as a proxy to institutional demand, which is currently held back by the 2.8% native staking reward rate. By comparison, stablecoin yields on Sky Lending (formerly MakerDAO) sat higher at 3.75%.

Weak spot ETH ETF demand and concerns with Ethereum’s roadmap

Excitement surrounding the ETF staking approval in the US, which occurred in late 2025, has not yet translated into sustainable demand. One could argue that the negative outcome was simply a result of bad luck, as the launch coincided with a broader crypto market downturn that began in early October after total market capitalization neared a $4 trillion all-time high.

ETH has underperformed the broader cryptocurrency market since October 2025, and there are no signs that a reversal is underway. Investor sentiment is also impaired by a staggering $735 million net loss from the Ethereum treasury firm Sharplink (SBET US) in 2025. The company, chaired by Ethereum co-founder Joseph Lubin, released these financial results on Monday.

The pace of native chain scalability might have contributed to Ether’s negative performance. For instance, Ethereum co-founder Vitalik Buterin said on Saturday that account abstraction, equivalent to smart accounts, will likely be shipped “within a year,” after more than a decade under development. Transactions will be able to reference each other’s data, enabling quantum-resistant wallets.

Another advantage of the upcoming Ethereum Hegota fork is paying gas fees in non-ETH tokens using special-purpose decentralized exchanges, while adding a “general-purpose public mempool” and removing “public broadcasters” in privacy platforms such as Railgun and Tornado Cash. Buterin also said that he expects “progressive decreases” of slot time and finality time in the long term.

Overall, ETH derivatives and onchain activity point to low conviction in a bullish breakout above $2,200, but at the same time, there is no indication of worsening conditions or domination from bears.
