On Wednesday, asset manager IDX filed for a combined Gold and Bitcoin ETF soon after the crypto mortgage approval by the U.S. Federal Housing Finance Agency (FHFA). Dubbed as the IDX Alternative FIAT ETF, the fund seeks to offer investors exposure to a blend of digital assets, putting a major focus on Bitcoin and Gold. Amid global market uncertainty, both asset classes have given strong returns in 2025, making them the best hedge against market volatility.
