Bitcoin ETF attracts $1.5 billion in five days: Institutions and Baby Boomer funds support BTC price

On March 4th, as Bitcoin prices experienced a significant pullback, the inflow of funds into spot Bitcoin ETFs provided important support to the market. Data shows that over the past five trading days, related ETFs attracted approximately $1.5 billion in total inflows, which some analysts see as a key factor in stabilizing Bitcoin prices.

Bloomberg ETF analyst Eric Balchunas stated in a recent program that this round of fund inflows likely comes from the so-called “Baby Boomer” traditional investor group, born between 1946 and 1964. He pointed out that despite Bitcoin falling about 50% from its October 2025 high, this group continues to buy into spot Bitcoin ETFs, with such a large scale that it even surprised market observers.

Balchunas believes that this inflow nearly covers all ten of the original spot Bitcoin ETF products launched, indicating that traditional capital market investors’ long-term willingness to allocate to digital assets is still growing. Previously, the market generally believed that cryptocurrencies were more popular among younger investors, with older investors having limited understanding of this emerging asset class. However, the current ETF fund flow situation shows that this stereotype is being broken.

On-chain data platform DefiLlama also confirms increased institutional participation. Currently, the total value of BTC held in Bitcoin ETFs exceeds $107 billion, accounting for about 12% of Bitcoin’s circulating supply. As more traditional financial institutions include Bitcoin in their asset allocation strategies, the influence of institutional funds in the market continues to expand.

Meanwhile, CEO Zac Townsend revealed that among the top 25 institutions holding Bitcoin ETFs since October 2025, 17 have continued to increase their holdings during the same period. This suggests that despite short-term price volatility, institutional investors remain inclined to pursue long-term positions through ETF channels.

Nate Geraci, co-founder of ETF research firm, also pointed out that unlike some retail investors who quickly exit during market downturns, ETF investors demonstrate greater patience and stability. He noted that there are no obvious signs of panic selling among ETF holders at this time.

Market participants believe that spot Bitcoin ETFs are changing the way traditional funds enter the crypto market. As institutional investors continue to allocate assets to BTC, the price movements of Bitcoin are becoming more closely linked to the traditional financial system.
