Bloomberg ETF analyst James Seyffart has predicted a significant influx of capital into crypto index exchange-traded products (ETPs) as market sentiment indicators, such as the fear and greed index, show rising interest. Seyffart specifically highlighted the 21Shares FTSE Crypto 10 ex-BTC Index ETF (TXBC) as a notable product to watch in 2026. This ETF tracks the FTSE Russell crypto index, which includes the top ten digital assets by market capitalization, excluding Bitcoin.
