Investment app Public has announced the integration of cryptocurrency trading within U.S. Individual Retirement Accounts (IRAs) and Roth IRAs. This new feature allows users to manage cryptocurrencies like Bitcoin, Ethereum, and Solana alongside traditional assets such as stocks and options, facilitating a more comprehensive retirement investment strategy. This development follows Public's acquisition of Alto's crypto retirement account business for $65 million, which brought approximately $600 million in assets under management.
