Bitcoin ETFs and the Arrival of Institutional Money

For most of its history, Bitcoin sat outside the familiar world of securities accounts. Buying it meant opening an account with a crypto platform or managing a wallet, and many pension funds, wealth managers and financial advisers were either not allowed or not willing to do either.

That changed in January 2024, when the US Securities and Exchange Commission approved the first exchange-traded funds that hold bitcoin directly. Since then, the asset can be bought in the United States much like a stock, through the same brokerage account used for equity funds and bonds.

This article explains what a spot Bitcoin ETF is, how it differs from holding coins yourself, what role similar products play in Europe and what the funds have changed in the market. It is not investment advice and does not assess whether such products are suitable for anyone.

What a spot Bitcoin ETF is

An exchange-traded fund, or ETF, is an investment fund whose shares trade on a stock exchange during regular trading hours. A spot Bitcoin ETF uses investor money to buy actual bitcoin, which a custodian holds on the fund's behalf. The share price follows the value of the coins held, minus fees.

The word spot distinguishes these funds from earlier products. Since 2021, US investors could already buy ETFs based on Bitcoin futures, contracts on the price at a future date. Such funds track the price only indirectly, and the cost of rolling expiring contracts into new ones can cause them to drift away from the Bitcoin price over time.

Large market participants, known as authorized participants, can create new fund shares or redeem existing ones. This mechanism keeps the share price close to the value of the underlying coins. When demand rises, new shares are created and the fund's bitcoin holdings grow. When investors sell, the process runs in reverse.

The long road to approval

Applications for a spot Bitcoin ETF in the US date back to 2013. For years, the regulator rejected them, citing concerns about market manipulation and investor protection on largely unregulated crypto trading venues. In 2023, a federal appeals court found that one of these rejections had not been adequately justified, which increased the pressure on the agency.

In January 2024, the regulator approved several applications at once. Spot ETFs for Ether, the native token of Ethereum, followed in the summer of 2024. The approval was not an endorsement of the assets themselves: the agency stressed that it had ruled on a fund structure, not on the merits of Bitcoin.

Fund shares or your own coins: the differences

Economically, both routes are tied to the price of Bitcoin. In practice, they differ in several ways that matter for anyone trying to understand the products.

• Custody: with an ETF, a specialized custodian holds the coins and the investor holds fund shares. With direct ownership, investors either manage their own keys or entrust them to a platform.
• Use: fund shares cannot be sent on the blockchain, used for payments or moved to a wallet. Direct holders can do all of this, but they also carry the risk of losing access.
• Fees: ETFs charge an annual management fee that is deducted from the fund's assets. Direct purchases involve trading fees and spreads, and self-custody may require dedicated hardware.
• Trading hours: Bitcoin trades around the clock, every day of the year. ETF shares trade only while the exchange is open, so large moves over a weekend show up in the share price on the next trading day.
• Rules and taxes: ETFs fall under securities law and its investor protection rules. Their tax treatment can differ from that of directly held coins and depends on the investor's country of residence.

The European route: ETPs instead of ETFs

Investors in Europe will rarely find a Bitcoin ETF in the strict sense. EU rules for retail funds, known as UCITS, require diversification, which a fund holding a single crypto asset cannot meet. Instead, exchange-traded products, or ETPs, have been listed on regulated exchanges in Germany, Switzerland and other countries for several years.

Most of these products are legally structured as notes, a form of debt security. Many are physically backed, meaning the issuer holds the corresponding coins with a custodian. Unlike fund assets, however, a note is a claim against the issuer, so its financial strength and the details of the collateral arrangement matter. The prospectus describes how the coins are secured and what happens if the issuer fails.

Because such notes are financial instruments, they fall under existing securities rules rather than under MiCA, the EU regulation for crypto-assets, which excludes financial instruments from its scope. For investors, this means that the familiar disclosure duties of the capital market apply, including a prospectus.

What the funds have changed

The most visible change concerns access. Advisers, family offices and institutional investors who work exclusively through securities accounts can now add Bitcoin exposure to portfolios without building their own custody setup. Quarterly filings in the US showed that, alongside hedge funds and wealth managers, a few public pension funds also bought shares in 2024.

In some respects, the products have also made the market more transparent. Issuers publish their holdings regularly, and daily fund flows have become a closely watched indicator. At the same time, many of the funds rely on the same small group of custodians, which concentrates operational risk in a few places.

Trading in ETF shares also ties Bitcoin more closely to the rhythm of traditional markets. Price moves during US trading hours and the behavior of other risk assets have become more relevant for observers. Whether this makes Bitcoin more stable or simply more correlated with stocks is an open question, and the answer may shift over time.

An ETF changes the wrapper around Bitcoin, not the asset inside it.

The limits of the wrapper

An ETF does not make Bitcoin less volatile. Its share price can fall sharply within days, just like the underlying asset. The fund structure also brings risks of its own: dependence on custodians and service providers, possible gaps between share price and asset value in stressed markets, and ongoing fees that reduce returns over time.

For anyone interested in Bitcoin as a technology, an ETF offers little. It provides no access to the network, no way to make a payment and no experience with keys or wallets. The product is designed for price exposure within an existing portfolio, nothing more.

It is also worth remembering what has not changed. The supply of Bitcoin remains capped at 21 million coins, the rules of the protocol are unaffected by the funds, and regulatory frameworks continue to develop in different directions in the US and in Europe.

A sober outlook

Spot Bitcoin ETFs mark a shift in how traditional finance deals with crypto assets. A product that regulators resisted for about a decade now belongs to the standard range of many brokers, and Ether has followed. Applications for funds tied to other crypto assets have already been filed, so the question of what belongs in an exchange-traded wrapper will stay on the agenda.

For individual investors, the essential questions remain the same as with any other investment: what exactly is held, who holds it, what it costs and how much fluctuation one can bear. The ETF has made Bitcoin easier to buy. It has not made the decision any easier.
