According to Eric Balchunas, the SEC has approved in-kind creation and redemption processes for all spot Bitcoin and Ether ETFs. This regulatory update is expected to improve liquidity and reduce tracking error for BTC and ETH ETFs, which could attract more institutional and retail trading activity. Enhanced ETF efficiency may also lead to tighter spreads and greater integration between crypto markets and traditional finance, directly impacting short- and long-term trading strategies for both Bitcoin and Ethereum (Source: Eric Balchunas).
