Mt. Gox collapse wiped out 850,000 Bitcoin, reshaping crypto security and repaying creditors with gains in 2024.

Mt. Gox, once the largest Bitcoin exchange handling up to 80% of global trades, collapsed in 2014 after losing 850,000 Bitcoin worth $473 million then and over $60 billion today. The exchange's founder, Mark Karpelès, was convicted for falsifying records but not theft, receiving no prison time. Creditors waited nearly a decade for repayments, which in 2024 exceeded their original losses due to Bitcoin's price surge. This collapse led to stronger crypto security standards and regulations worldwide.
