[Warren and Sanders: Criticize Trump Administration's Support for Bitcoin and Crypto Retirement Accounts] U.S. Senators Warren and Sanders have criticized the Trump administration for allowing Bitcoin and cryptocurrencies to be included in 401K retirement accounts, calling the move potentially dangerous. Previously, some financial institutions had started offering cryptocurrency investment options, with supporters arguing that this could attract younger investors.
