After a shaky start to March, Bitcoin ETFs just hit a ten-day hot streak, pulling in a total of $1.06 billion as of March 28, 2025. This inflow surge, starting around March 14, signals a significant turnaround from earlier in the month when these same ETFs bled $409 million in a single day (March 6).
This renewed interest has pumped the total Assets Under Management (AUM) for Bitcoin ETFs from $88 billion on March 10 to a hefty $98.3 billion by March 28. However, despite this recent bullish activity, March is still poised to be the second-worst month for net outflows, currently standing at $603 million. To put that in perspective, it’s already surpassed April 2024’s $345 million outflow, but it trails February’s record-breaking negative flow.
While Bitcoin ETFs are navigating choppy waters with a $93 million net outflow over the last 30 days, Ethereum ETFs are showing a different current. Over the same period, Ethereum ETFs have attracted a modest $5 million in net inflows according to CoinMarketCap data. Interestingly, Bitcoin ETFs currently hold assets equivalent to 6.01% of Bitcoin’s total market cap, while Ethereum ETFs represent a smaller 3.87% slice of Ethereum’s market cap.
Together, Bitcoin and Ethereum ETFs now account for 5.75% of the entire cryptocurrency market capitalization. Whether this inflow trend for Bitcoin ETFs continues into April remains to be seen, but for now, it’s a welcome change of pace after a bumpy month.
