Billy Markus, co-creator of Dogecoin who operates under the X handle Shibetoshi Nakamoto, has publicly supported Bitcoin's potential use as an alternative to traditional retirement savings plans.
The comments emerged during discussion on X as cryptocurrency markets experienced significant declines. Bitcoin fell to a three-month low below $63,000, while Dogecoin dropped to $0.055, a level not seen since June 2023. Liquidations reached $1.92 billion over a 24-hour period, with long positions accounting for $1.59 billion of the total, according to CoinGlass data.
When another user suggested Bitcoin serves as "a good 401k replacement," Markus responded by stating that "Bitcoin has the best reason to exist as the OG," emphasizing its position as the original cryptocurrency.
Growing Institutional Support for Crypto Retirement Plans
Cryptocurrency integration into retirement accounts has expanded as adoption increases. Asset manager Fidelity, one of the largest 401(k) providers in the United States, permits Bitcoin in employer-sponsored 401(k) plans subject to employer approval. The firm introduced a standard account option in April 2022 that enables 401(k) account holders to add Bitcoin alongside traditional investment options.
Fidelity Investments further expanded this offering in 2025 by announcing a new retirement plan allowing U.S. adults to invest directly in cryptocurrencies including Bitcoin, Ethereum, and Litecoin.
