U.S. spot Bitcoin ETFs saw a whopping $10 billion in trading volume in their first week, but some crypto execs are concerned about their impact on the industry. Critics like Eco CEO Andy Bromberg argue that ETFs could lead to greater centralization and give traditional financial institutions too much control over the market. While acknowledging the benefits of ETFs, Bromberg urges the crypto community to help new investors self-custody their funds to avoid a Wall Street-owned financialized asset. Others, like Suku CTO Lucas Henning, believe that self-custodying crypto assets will become easier in the future, reducing the need for ETFs.
