With the crypto-friendly Mr. Trump back in the White House, Wall Street is poised to unveil a new generation of risky products in a $3.20 trillion industry that caters to the tastes of investors ranging from institutional novices to die-hard retail investors. Executives and lawyers involved in ETFs say they describe products ranging from defensive ETFs for crypto-curious professional fund managers to full-spectrum speculative bets for self-described depraved gamblers. Industry investors and lawyers say riskier cryptocurrency ETFs are likely to focus on a variety of digital tokens, sometimes using leverage, options or quantitative strategies.
