While some providers were offering Crypto windows in 401(k) plans, I was vehemently against it because the Department of Labor (DOL) was against it. The volatility of crypto was one thing, security was another issue.
The introduction of spot Bitcoin and Ethereum Exchange Traded Funds (ETFs) means that Bitcoin and Ethereum investments will be allowed in 401(k) plans. The ETFs have helped eliminate much of the volatility of Bitcoin as well as security issues as they can be held in a custodial account, rather than a virtual wallet that can be hacked. A change in administration regardless of who wins, may install a DOL that will be friendlier to crypto investors and providers. But if the Securities and Exchange Commission is OK with ETFs, the DOL will eventually be too.
