Biotech Billionaire Bryan Johnson Wants to Live to 2140 and Watch Bitcoin’s Last Halving — Can Anti-Aging Science Get Him There?

Bryan Johnson’s Ambitious Plan to Witness Bitcoin’s Last Halving in 2140

Bryan Johnson, the entrepreneur known for his ventures in biotech and payments, has declared a personal mission to live long enough to witness Bitcoin's final halving in the year 2140.

Posting on X, Johnson said plainly,

"Last Bitcoin halving is in 2140. I'm gonna be here for that — and make sure you are too."

This statement came before his appearance at Bitcoin 2025, a conference running from 27 to 29 May in Las Vegas, where he shared his vision of extending human life alongside Bitcoin’s long-term trajectory.

How Does Johnson Plan to Defy Aging and Death

Johnson’s interest in longevity isn’t theoretical.

He has been actively leading “Project Blueprint”, a research initiative aimed at significantly slowing or reversing biological aging.

The project uses a mix of regenerative medicine techniques, including red-light therapy and plasma infusions, alongside data-driven biometrics to monitor progress.

Johnson’s approach involves rigorous self-experimentation, supported by continuous tracking of key biomarkers to measure his biological age.

Fortune has reported that Johnson spends millions annually to maintain his youth through these experimental methods.

His high-profile investment and leadership in longevity science have attracted global attention, merging biohacking with advanced technology in a way few have attempted.

What is Bitcoin’s Last Halving and Why Does it Matter

Bitcoin’s code dictates that every roughly four years, the rewards given to miners for validating transactions are cut in half.

This halving slows the rate at which new bitcoins are created, gradually tightening the total supply until it reaches a maximum cap of 21 million coins.

The last halving is expected to occur around 2140, after which no new bitcoins will be mined.

This milestone represents the endpoint of Bitcoin’s built-in monetary issuance and is a significant event in the cryptocurrency’s lifecycle.

Connecting Longevity and Decentralised Finance at Bitcoin 2025

Johnson’s appearance at the Bitcoin 2025 conference underscores an intriguing crossover between longevity science and cryptocurrency communities.

Bitcoin 2025 is hosting a variety of prominent figures from politics, finance, and technology, including US Vice President JD Vance and Senator Cynthia Lummis, known for her work on Bitcoin-related legislation.

The event aims to explore themes of financial independence, innovation, and resilience amid changing regulations.

Alongside Johnson, other notable speakers include leaders like David Marcus of Lightspark, Dan Morehead of Pantera Capital, Arthur Hayes of Maelstrom, Elizabeth Stark from Lightning Labs, and Jack Mallers of Strike.

Their discussions focus on Bitcoin’s future challenges and opportunities, ranging from scaling solutions to market dynamics and mass adoption.

Why Johnson’s Vision Adds a New Layer to Bitcoin’s Future

By pledging to be alive for the final Bitcoin halving, Johnson links the concept of radical life extension with the enduring nature of Bitcoin’s protocol.

This fusion reflects a broader theme of self-sovereignty — both over one’s health and financial destiny.

As the Bitcoin network progresses through its halving cycles, culminating in the final event over a century from now, Johnson’s efforts pose a provocative question: can human lifespan be extended to match the longevity of this digital asset?

Whether or not this vision will materialise, Johnson’s approach encourages a broader conversation about how emerging technologies could reshape not only how we live but how we think about time, value, and legacy in an increasingly digital world.

Johnson’s commitment highlights a rare blend of long-term thinking rarely seen in today’s fast-paced tech world, making his talk at Bitcoin 2025 a notable point of interest for attendees and observers alike.
