The infamous Mt. Gox exchange, accounting for over 70% of all Bitcoin transactions in 2013, is known for suffering the biggest Bitcoin heist of all time worth 850,000BTCs. One month after filing for bankruptcy in Japan, where the exchange was based, 200,000BTCs were recovered and later put in control of trustees to manage the bankruptcy proceedings.

Frenchman Mark Karpeles purchased Mt. Gox from Jed McCaleb in 2010 in exchange for 50% of the profits for the first 6 months and a 12% equity from that point onwards. Karpeles served as the CEO of the exchange and was charged with embezzlement after the major loss to which he pled innocent. In March 2019, he was cleared of embezzlement charges by a Japanese court. Nonetheless, he was charged with 2.5 years suspension for electronic record tampering, charges to which he has appealed.
Wednesday, Karpeles told Foreign Correspondents Club of Japan reporters he was ready to start “from zero” with a new blockchain project. He is currently the Chief Technology Officer (CTO) at an IT company called Tristan Technologies. The company specialises in privacy protection and is aiming to create an operating system much faster than the ones used today.
Japanese culture was always an area of interest for Karpeles, especially due to Japanese games and animation. For that reason, he chose to move when he was only 20 years old. He was quoted saying “my love for Japan has not changed” and that “Japan used to be engineering superpower in terms of its PCs but right now, taking the cloud, for example, it is the U.S. that dominates. But still I believe in the potential Japan has and I would like to develop that”.

With over 2.4M tokens and widespread misinformation in crypto, we cut
through the noise and consistently find winning assets.
























Can I trust Cryptonary's calls?
Yes. We've consistently identified winners across multiple cycles. Bitcoin under $1,000, Ethereum under $70, Solana under $10, WIF from $0.003 to $5, PopCat from $0.004 to $2, SPX blasting past $1.70, and our latest pick has already 200X'd since June 2025. Everything is timestamped and public record.
Do I need to be an experienced trader or investor to benefit?
No. When we founded Cryptonary in 2017 the market was new to everyone. We intentionally created content that was easy to understand and actionable. That foundational principle is the crux of Cryptonary. Taking complex ideas and opportunities and presenting them in a way a 10 year old could understand.
What makes Cryptonary different from free crypto content on YouTube or Twitter?
Signal vs noise. We filter out 99.9% of garbage projects, provide data backed analysis, and have a proven track record of finding winners. Not to mention since Cryptonary's inception in 2017 we have never taken investment, sponsorship or partnership. Compare this to pretty much everyone else, no track record, and a long list of partnerships that cloud judgements.
Why is there no trial or refund policy?
We share highly sensitive, time-critical research. Once it's out, it can't be "returned." That's why membership is annual only. Crypto success takes time and commitment. If someone is not willing to invest 12 months into their future, there is no place for them at Cryptonary.
Do I get direct access to the Cryptonary team?
Yes. You will have 24/7 to the team that bought you BTC at $1,000, ETH at $70, and SOL at $10. Through our community chats, live Q&As, and member only channels, you can ask questions and interact directly with the team. Our team has over 50 years of combined experience which you can tap into every single day.
How often is content updated?
Daily. We provide real-time updates, weekly reports, emergency alerts, and live Q&As when the markets move fast. In crypto, the market moves fast, in Cryptonary, we move faster.
How does the success guarantee work?
If our approach to the market doesn’t beat the overall crypto market during your subscription, we’ll give you a full refund of your membership fee. No questions asked. For quarterly and monthly subscribers this is applicable once your subscription runs for 6 consecutive months.
