Investment platform Public has introduced cryptocurrency trading within Traditional and Roth IRA accounts. This new feature allows users to incorporate over 40 cryptocurrencies, including Bitcoin, Ethereum, and Solana, into their retirement portfolios while benefiting from tax advantages such as deferred or tax-free gains. Public CEO Leif Abraham highlighted that cryptocurrencies have evolved from experimental to global assets, and this move addresses the lag in retirement investment tools adapting to this asset class.
