Bitcoin ETFs Dominate 89.46% of Global Crypto Fund Market

Bitcoin ETFs have established a commanding presence in the global crypto fund market, holding nearly 90% of all assets under management (AUM). This dominance was highlighted on April 21, 2025, by ETF analyst Eric Balchunas, who noted that despite the anticipated launch of numerous altcoin and meme coin ETFs this year, Bitcoin's market share is expected to remain robust. The trend indicates a sustained preference for Bitcoin among investors, who view it as a more secure and mature asset compared to other cryptocurrencies.

Institutional investors continue to favor Bitcoin ETFs, with data from April 20 showing that these funds hold around $100.59 billion in AUM, representing 89.46% of all crypto fund investments. In contrast, Ethereum ETFs trail significantly with only $7.05 billion, or 5.72% of the total. Index and basket funds account for a minor 2.52%, while other altcoin funds form an even smaller share. This pattern reflects a consistent view among investors that Bitcoin is a more reliable investment option within the volatile crypto ecosystem.

The strong institutional backing for Bitcoin ETFs is further supported by robust inflows. Weekly figures reveal inflows of 3,900 BTC, which is about 5.52% of the total Bitcoin supply. Fidelity’s Bitcoin ETF alone saw inflows of 306 BTC this week, valued at nearly $27 million. Additionally, the iShares Bitcoin Trust ETF reported a 3% price gain, with trading volume significantly above its competitors. These figures underscore the continued confidence in Bitcoin as a stable and valuable investment.

In contrast, altcoin ETFs, including those focused on Ethereum, struggle to gain traction. Ethereum ETFs reported total assets of $5.33 billion on April 21, with no significant inflows or outflows. Ethereum ETF holdings represent only about 2.72% of the token’s circulating supply, indicating limited investor appetite for non-Bitcoin crypto ETFs. This lack of interest is exacerbated by macroeconomic uncertainty and tightening regulations, which create additional barriers for altcoin ETFs to attract capital.

Analysts believe that Bitcoin's dominance in the crypto fund market is likely to persist, with projections estimating that it will retain an 80-85% market share in the foreseeable future. This sustained preference for Bitcoin signals long-term stability in a volatile market, as investors continue to view it as a more secure and mature asset compared to other cryptocurrencies. The trend suggests that despite the hype around altcoins and meme coins, Bitcoin ETFs will maintain their iron grip on the global crypto fund market.
