401k Account

A 401k is an employer-sponsored retirement account in the United States, named after the section of the tax code that created it in 1978. Employees contribute pre-tax or Roth dollars from each paycheck, often with an employer match, up to an annual employee limit of 23,500 dollars in 2025, with higher limits for those 50 and older.

Why it matters

The 401k is the primary retirement savings vehicle for tens of millions of American workers, holding trillions of dollars in aggregate. Contributions reduce current taxable income in the traditional version or grow tax free in the Roth version, and gains compound without annual capital gains taxes. Withdrawals before age 59 and a half generally incur a 10 percent penalty plus income tax.

Investment menus are set by employers and usually consist of mutual funds and target-date funds. Direct exposure to alternatives is rare, though some plans added a bitcoin option beginning in 2022, and self-directed brokerage windows can widen the menu.

In the gold vs bitcoin debate

Most 401k participants can only reach either asset indirectly, through gold funds, mining stocks, or, where offered, bitcoin funds and ETFs. Savers who want physical gold or self-custodied bitcoin typically roll old 401k balances into a self-directed IRA instead. The rise of spot ETFs for both assets is slowly narrowing this gap, putting gold and bitcoin exposure a menu decision away for mainstream retirement savers.
