The Norwegian takes home the $60,000 first prize plus a 0.6 bitcoin bonus offered by tournament sponsor FTX. It is the largest prize pot ever offered in an elite online chess event. After the see-saw match ended with Carlsen punching the air in delight, the champ said: "It's pretty sick! I came back five times when I needed it, and I also lost twice. "It's absolutely insane. I am just so happy to have pulled through. It's a massive, massive relief."
