21Shares has introduced two cryptocurrency index ETFs in the United States, marking a significant development in regulated crypto investment products. The FTSE Crypto 10 Index ETF (TTOP) and the FTSE Crypto 10 ex-BTC Index ETF (TXBC) are now available, with management fees of 0.50% and 0.65% respectively. These ETFs are registered under the U.S. Investment Company Act of 1940, offering investors exposure to the top ten digital assets through FTSE Russell indices. The ETFs are designed to provide diversified access to the cryptocurrency market, rebalancing quarterly to maintain alignment with the indices. This launch represents a step forward in providing regulated, diversified crypto investment options without the need for direct asset management.
