About the Book

In 2014, 850,000 Bitcoin vanished. Mt. Gox had handled 70% of global trading. Then it collapsed. The Hidden Monster tells how Japan became crypto's capital and how the world's largest exchange became its greatest disaster.

Lost decades. Deflation. Zombie banks. Yet Japan built mobile internet before smartphones. Emoji. QR codes. Mrs. Watanabe moved global currency markets from her kitchen table. Bitcoin arrived. Mt. Gox set up in Tokyo and rose. Warnings ignored. Too big, too fast.

The Nue, Japan's chimera monster, had returned. Part deflation, part stagnation, part digital revolution. One disaster. This book shows how Japan faced a hybrid crisis and how the collapse shaped crypto regulation worldwide. Same lessons. Different century.
