On June 9th, it was reported that as the threat of kidnapping cryptocurrency holders escalates globally, the well-known Bitcoin investment family “Taihuttu Family” has taken a series of extreme security measures to ensure the safety of the crypto assets it holds. The family founder, Didi Taihuttu, disclosed that they have abandoned the traditional hardware wallet storage method and instead segmented and encrypted cryptocurrency mnemonic phrases, which are scattered and hidden across four continents around the world.
Taihuttu said that in the past eight months, they have built a hybrid storage system. The specific approach is to split the encrypted mnemonic phrases, with one part engraved on a fireproof steel plate and hidden in secret locations across four continents: Europe, Asia, South America and Oceania. The purpose of doing this is that even if a certain storage location encounters an accident, such as fire, theft or being discovered by lawbreakers, it will not lead to the loss of the entire asset. Another part of the mnemonic phrases is stored through blockchain-based encryption services. This storage method takes advantage of the decentralized and encrypted features of blockchain technology to further enhance the security of mnemonic phrases. Moreover, this system has also designed a unique security mechanism. As long as the specific words that have been modified are remembered, even if the attacker acquires some mnemonic words, they cannot successfully unlock all the assets.
Currently, approximately 65% of the Taihuttu family’s crypto assets are distributed in cold storage across four continents in cold wallets. Cold wallets, not connected to the Internet, greatly reduce the risk of being remotely attacked and stolen by hackers. The remaining 35% of the assets are kept in multi-signature wallets or decentralized exchanges for daily transactions and expenditures. A multi-signature wallet requires the joint signature of multiple private keys to complete a transaction, enhancing the security of assets. Decentralized exchanges provide them with convenient trading venues to meet the daily asset circulation needs.
In recent years, with the vigorous development of the cryptocurrency market, the wealth of cryptocurrency holders has been continuously increasing, which has also attracted the attention of lawbreakers. According to media reports, at least five kidnapping cases related to cryptocurrencies have occurred in France in recent months. In 2025, there were dozens of recorded cases of this kind around the world. The criminals’ target is very clear, which is a ransom worth millions of dollars in cryptocurrency. In the United States, several kidnapping incidents have also occurred targeting executives of cryptocurrency companies and their families. The victims were not only shot with pistols and kidnapped, but in some cases, their fingers were even cut off.
For instance, John Woeltz, known as the “cryptocurrency bigwigs of Kentucky”, was arrested on suspicion of kidnapping and torturing an Italian Bitcoin millionaire in the Manhattan area of New York. During his imprisonment, the victim, Michael Valentino Teofrasto Carturan, suffered inhumane torture, including being tied to a chair, having his feet soaked in buckets and electrocuted, being splashed with urine, having gun fingers, having his arms and legs cut with saws, and being tied and hung from the apartment window for a time.
In the face of such a severe security situation, the Taihuttu family’s approach offers new security ideas for cryptocurrency holders. By distributing assets across multiple regions around the world and adopting advanced encryption technologies and storage methods, the risk of total asset loss due to a single security vulnerability can be effectively reduced to a certain extent. However, this approach is not without drawbacks. Decentralized storage leads to an increase in management costs, including the maintenance of storage locations and the monitoring of different storage methods. For ordinary cryptocurrency investors, it may be difficult to imitate this complex and costly storage method. However, in any case, in the current environment where the security threats to cryptocurrencies are becoming increasingly severe, all investors should attach great importance to the issue of asset security, rationally choose and optimize storage methods based on their own circumstances, and enhance their awareness of security prevention.
