US 401(k) Proposal Leaves Door Open to Altcoins, but Hurdles Remain

The significance here is procedural rather than substantive: a door left ajar is not an invitation, and the proposal's silence on smaller tokens shifts the real gatekeeping to plan fiduciaries and recordkeepers who must weigh liquidity, custody and suitability without clear guidance. That ambiguity cuts both ways—it preserves optionality for sponsors while exposing them to judgment calls that could invite scrutiny. The practical barriers, not the legal text, will determine whether altcoins ever appear in retirement menus, and whether sponsors show any appetite for that exposure is the open question worth watching.
