Former Venmo CEO and renowned anti-aging researcher Bryan Johnson stated on social media: "The last Bitcoin halving will occur in 2140, and I will be there to witness that moment, making sure you can be there too."

It is reported that Johnson is known for his radical anti-aging experiments, previously conducting a controversial family plasma exchange experiment. In this experiment, he underwent plasma exchange with his 19-year-old son and his father in his 70s, aiming to achieve anti-aging effects by infusing young plasma.
