Marcus Chen was the world's most brilliant blockchain developer—until his own partner framed him for the largest crypto heist in history: 1.5 billion dollars stolen from Bytex Exchange. Betrayed, imprisoned, and murdered in his cell, Marcus wakes up three years in the past with every memory intact. This time, he won't be the fall guy. This time, he'll be the phantom who steals back everything—and destroys everyone who destroyed him. Armed with future knowledge, unmatched coding skills, and a burning thirst for revenge, Marcus rebuilds his empire from nothing. But when he discovers the theft was orchestrated by a shadowy North Korean hacking syndicate with ties to his own family, the game changes from personal vendetta to global warfare. In a world of digital currencies and invisible killers, Marcus must become something far more dangerous than a hacker. He must become the Crypto Phantom.
