He created Mt. Gox, Ripple, and Stellar—three of the most colossal names in the crypto universe—and, in a way, left them mired in controversy.

Few people shaped the early infrastructure of cryptocurrencies more than Jed McCaleb.
Most casual users still don’t know his name.
He originally built Mt. Gox before parting ways with it.
After that, the exchange collapsed in a cataclysmic manner.
Then he co-founded Ripple.
That partnership ultimately deteriorated severely as well.
Disagreements over direction and control—allegedly—pushed him to leave.
So he launched Stellar afterward.
Another significant blockchain network.
On crypto forums, people joked that Jed somehow kept abandoning massive projects just before the chaos came for them.
Despite the controversies, his footprint in crypto history remained enormous.
A programmer quietly helped shape multiple billion-dollar ecosystems, while rarely becoming the focus himself.
