A National Institute on Retirement Security survey found 77% of Americans view crypto in workplace retirement plans as risky, with 46% calling it very risky and 53% opposing employers offering it at all. Greenwald Research polled 1,203 U.S. adults aged 25 and older from October 24 to November 14, 2025, weighting results by age, gender, and income. Retirement anxiety is widespread: 80% say the United States faces a retirement crisis, up from 67% in 2020; 61% worry about financial security in retirement; 68% say preparing has gotten harder; 77% say debt blocks adequate saving; 47% have less than $100,000 saved and 18% have none; and only 9% correctly estimated the income $100,000 would generate under a common withdrawal guideline. Social Security supplies about 52% of income for older Americans, while traditional pensions remain available to about 17% of workers. The caution contrasts with Trump administration moves to expand alternative assets including crypto in 401(k)s—Labor Department withdrawals of discouraging guidance in 2025, an August 2025 executive order, and a March 2026 proposed rule covering more than 90 million savers—drawing a June request from Senators Bernie Sanders and Elizabeth Warren and Representative Bobby Scott to withdraw the plan over volatility, fraud, fees, and liquidity concerns. A Federal Reserve survey found 10% of U.S. adults held or used crypto in 2025, up from 7% in 2024. In Japan, crypto remains excluded from iDeCo and corporate defined contribution plans despite the July 2026 Financial Instruments and Exchange Act amendment.
