It’s no surprise that U.S. Sen. Elizabeth Warren (D-Mass.) is expressing concerns about Fidelity Investment’s plan to allow Bitcoin in 401(k) retirement plans.

Warren asked Fidelity “about the appropriateness” of its plans and mirrored the concern of the Department of Labor (DOL) about bitcoin’s volatility, describing investing in crypto as “a risky and speculative gamble.”

Knowing a thing or two about Warren’s background, this isn’t surprising and the debate over Fidelity and the DOL views on crypto investing will continue.
