Wall Street’s Bitcoin ETF Frenzy Overshadows Ethereum’s Silent Rally

While institutional money floods into Bitcoin ETFs like a hedge fund happy hour, Ethereum just hit an all-time high without the fanfare—proving once again that crypto’s ’quiet kid’ delivers while the loud money chases headlines.

Funny how the ’digital gold’ narrative always seems to coincide with brokers needing a new commission vehicle.

TLDR

• Bitcoin ETFs recorded over 3.6 billion dollars in net inflows by May 20.
• This marks a full recovery from the 4.6 billion dollar outflows seen in early 2025.
• BlackRock’s iShares Bitcoin Trust led the inflows with 287.45 million dollars in one day.
• Fidelity’s Bitcoin ETF followed with 23.26 million dollars in daily inflows.
• Smaller Bitcoin ETFs like ARKB and BITB also saw steady inflow gains.

Monthly net inflows into U.S. Bitcoin ETF products have exceeded $3.6 billion as of May 20, 2025. The surge marks a complete reversal of the earlier $4.6 billion outflows between February and March. As ethereum funds also gain traction, May becomes the strongest month of 2025 for both major crypto ETFs.

With strong demand, Bitcoin ETFs have become a central vehicle for crypto-related exposure in traditional finance. Their increasing volume signals continued institutional participation. The market remains active as Bitcoin ETF performance surpasses expectations.

Ethereum ETFs Record Best Month of the Year
