Observation of Wealth Figures Harry Yeh, a cryptocurrency investor worth 2.4 billion yuan, fell from the 30th floor naked and died on the spot. The apartment door was open, and the interior was flipped upside down. His Brazilian girlfriend who lives in the same building as him said, 'I have no idea.'. The three words' naked ',' fallen ', and' 30th floor 'together no longer require further explanation. In 2013, when Bitcoin was still at $60, he bought his first transaction for $500. Later, starting at 250000 US dollars, he reached 2.4 billion US dollars and became the soul of the Fantom ecosystem. And then he died in South America. What is South America? Gunfights, gangs, drug trafficking. Even Honduras is there. He lived in Abu Dhabi, had his career in Miami and Dubai, but unfortunately died in Paraguay. This type of violent incident targeting cryptocurrency tycoons is not the first, nor will it be the last. The data for the first half of 2026 has already explained everything. Previously, the richest people in the cryptocurrency industry were most afraid of hackers. Now, they may be more afraid of someone standing at your doorstep holding a wrench. There is a dangerous shift in criminal activities targeting cryptocurrency holders: from online theft to offline robbery. Hackers need skills to break into your computer. But kidnapping you, breaking into your home, using guns to force you to hand over your wallet password, and even directly forcing you to transfer coins, doesn't require much technical expertise. This is the increasingly popular "wrench attack" nowadays. Cold wallets can prevent hackers, but they cannot prevent violence. From the kidnapping and murder of a wealthy Russian couple, to the kidnapping of David Balland, co-founder of Ledger in France, to the beating, electrocution, and coercion of American cryptocurrency investors to hand over their Bitcoin wallet passwords The targets of criminals are changing: I used to focus on the exchange, but now I'm starting to focus on people. Even some people have become targets of criminals by publicly displaying their holdings. What you post online is wealth, but what criminals see is a 'target portrait'. What is even more alarming is that these are no longer isolated cases. According to statistics from different institutions, violent attacks against cryptocurrency holders in the first half of 2026 have reached the level of tens of millions of dollars, and the number of related cases continues to increase. Of course, different institutions have different statistical approaches, and numbers cannot be simply added together. But the trend is very clear: The cryptocurrency industry is transitioning from a hacker war to a personal security war. A truly mature cryptocurrency asset management is not just about cold wallets, hardware wallets, multi signature, and mnemonic word separation. Now, it should also include: not flaunting wealth, not publicly holding positions, not revealing the true size of assets, not easily revealing the location, and not letting strangers know how much money you have. Because at this stage, your biggest security vulnerability may no longer be your wallet, but yourself. We used to say: if it's not your private key, it's not your coin. Now it may be necessary to add: if it's not your private key, it's not your coin. But if others know you have a private key, you will become a target. The more wealth one has, the more one should learn to be invisible. True financial freedom may not be about letting everyone know how much money you have, but about no one knowing how much money you have.
