The momentum for cryptocurrency exchange-traded funds (ETFs) held steady on Tuesday, April 21, but the underlying dynamics are becoming increasingly uneven. Ether ETFs once again led the charge with $43.36 million in net inflows, extending their inflow streak to nine consecutive days. In contrast, Bitcoin ETFs recorded a modest $11.84 million net inflow, marking their sixth straight day of positive flows but revealing growing fragility beneath the surface. XRP and Solana ETFs remained entirely inactive, with zero flows recorded.
Ether ETFs: Broad Participation but Legacy Outflows Persist
Ether ETFs demonstrated robust demand, driven primarily by BlackRock's offerings. The ETHA fund led with $37 million in inflows, while the ETHB product added $15.46 million. Grayscale's Ether Mini Trust contributed $3.93 million, and Bitwise's ETHW brought in $1.99 million. However, selling pressure was not absent. Grayscale's legacy ETHE fund saw $12.14 million in outflows, and Fidelity's FETH lost $1.99 million. Despite these outflows, the net result was firmly positive. Total trading volume for ether ETFs reached $648.88 million, and net assets stood at $13.66 billion.
Bitcoin ETFs: Narrowly Positive Amid Widespread Outflows
Bitcoin ETFs extended their inflow streak to six days, but the gains were minimal. The net inflow of $11.84 million masked a broader struggle. BlackRock's IBIT remained the anchor, attracting $39.34 million. Grayscale's Bitcoin Mini Trust added $17.26 million, and Morgan Stanley's MSBT continued its steady climb with $10.80 million in inflows.
On the other side, outflows were widespread. Grayscale's GBTC led with $17.51 million in outflows, followed by Ark & 21Shares' ARKB at $14.52 million. Bitwise's BITB lost $12.70 million, Fidelity's FBTC shed $6.55 million, and VanEck's HODL saw $4.27 million exit. The net result was positive only by a narrow margin. Trading volume for bitcoin ETFs was $1.86 billion, and net assets slipped slightly to $99.08 billion.
XRP and Solana ETFs: No Activity
Both XRP and Solana ETFs recorded no trades or flows on April 21. XRP ETF net assets remained at $1.07 billion, while Solana ETFs held steady at $863.18 million. The lack of activity suggests that the initial excitement around these altcoin ETFs may be waning, or that investors are temporarily sidelined.
Divergence in ETF Momentum
The contrast between ether and bitcoin ETFs is becoming more pronounced. Ether is building a steady inflow trend with broad participation across multiple funds. Bitcoin, while still recording inflows, is increasingly reliant on a small group of dominant funds—particularly BlackRock's IBIT—to offset persistent outflows elsewhere. The overall trend remains positive, but the balance is tightening. Traders are watching closely to see if bitcoin's fragile streak can survive another day of mixed signals.
