Agressé pour ses cryptos : témoignage et guide de sécurité

The speaker recounts a true story involving one of his subscribers who was physically assaulted for possessing cryptocurrency. This individual, not a millionaire, was generally cautious about security, yet still fell victim to an attack. The subscriber wanted to share his experience to serve as a lesson, emphasizing that such aggressions and kidnappings can happen to anyone. The video is divided into two parts: the first details the subscriber's ordeal, with anonymized details, and the second provides actionable steps to mitigate the impact of such incidents. The subscriber is described as an average person, not someone flaunting wealth. He invested a modest amount, a few thousand euros, in cryptocurrency and maintained a low profile on social media. This detail is crucial because, contrary to popular belief, crypto-related kidnappings and aggressions in France (which average almost one per week since early 2026) don't only target influencers or wealthy individuals. Even those with relatively small crypto holdings and anonymity can become targets. The subscriber was aware of the risks and had implemented several security protocols, such as avoiding public display of wealth and refraining from sharing sensitive information online, yet he still couldn't understand how the aggression occurred. The incident began when the subscriber returned home and was attacked by a group of young, masked individuals. These assailants were knowledgeable about cryptocurrency, understanding how to transfer funds and operate on exchanges and wallets. They physically assaulted him to force him to transfer his cryptocurrencies. The subscriber primarily held crypto on exchange platforms for daily trading, with the bulk of his funds secured on hardware wallets using multisignature technology. The attackers forced him to transfer the funds accessible on his exchanges to their wallets. Being alone and outnumbered, he had no choice but to comply. His use of hardware wallets and multisignature, which he didn't have on him, proved to be a saving grace, as the attackers only focused on easily accessible funds, which amounted to a few thousand euros – a "derisory" sum compared to the risks involved. After securing these funds, the assailants fled. Physically, the subscriber sustained minor injuries, but the psychological impact was severe, and he remains affected weeks later. He filed a police report, but found law enforcement largely uninformed about cryptocurrency-related crimes. The police understood a theft occurred but conveyed that without leads, little could be done. Determined to find answers, the subscriber investigated how the attackers identified him, given his security consciousness. He checked Telegram and Discord groups for any leaked information, and social media for any inadvertently revealed sensitive data, but found no direct links. He then considered data breaches, where malicious actors might combine various pieces of information to identify targets. While plausible, this seemed unlikely for him due to his minimal online presence. Discussions with family members led to a crucial idea: checking his vehicle's surveillance cameras to see if he had been followed. This proved insightful. The footage revealed his vehicle being tailed at times. He pondered why his ordinary car, not a luxury vehicle, would be targeted. He then recalled attending a general investment conference shortly before the attack, not specifically crypto-focused, but covering stocks, real estate, and some crypto. During a group discussion, he simply raised his hand when asked if anyone owned cryptocurrency. This seemingly innocuous action appears to be the trigger. He inferred that after the conference, individuals started following him, first in the parking lot, then on his drive home. This suggests that despite his online precautions, the vulnerability was a simple, real-world identification. The gravity lies in the fact that he never specified the amount of crypto he held or boasted of success; he merely indicated possession. This implies that criminals are now willing to resort to physical aggression for potentially small sums, risking years in prison for a few hundred or thousand euros. The speaker emphasizes that no one is safe, regardless of the amount of crypto held, as even small portfolios are targeted due to relatively lenient penalties and the ease of forcing transfers from smartphones. The subscriber's experience highlights that even with robust protocols, possessing crypto makes one a potential target. His limited funds on exchanges, rather than easily accessible hot wallets, minimized his losses. The subscriber is now rebuilding, undeterred by the incident but more determined to enhance his security. Physically, he is recovering, but mentally, it remains a challenge. The speaker commends his courage in sharing his story, believing it will benefit others. The second part of the video offers practical advice. First, despite police limitations, reporting the crime is essential for creating a record, potentially linking cases, and for insurance or disability claims. Second, the adage "live happily, live hidden" is paramount. Avoid revealing crypto ownership in public. Be particularly wary in social settings, like family dinners or gatherings with friends where acquaintances might be present. Even seemingly private conversations, such as at a coffee machine with a colleague, can be overheard by malicious individuals. Third, never check crypto portfolios or applications in public spaces, such as queues, trains, or buses. Opportunistic criminals can recognize app interfaces like Binance or Hyper Liquid with a quick glance. Disable notifications on your smartphone that might reveal crypto activity (e.g., "Bitcoin surpassed $90,000"), as even these subtle hints can attract attention. Fourth, brief trusted friends and family about your crypto holdings and the associated risks, including the possibility of aggression or kidnapping. Instruct them to worry if you don't make contact for over 24 hours. While discretion is key, having a few trusted individuals aware is vital. Fifth, avoid flaunting wealth or crypto gains on social media. Use pseudonyms and avoid combining your name and surname. Use profile pictures that don't directly show your face. Maintain separate email addresses for crypto exchanges and social media accounts, ideally one for each platform, to prevent cross-identification. Never use professional email addresses for crypto-related activities. Sixth, refrain from wearing crypto-branded merchandise (t-shirts, goodies, hats) in public. While it might be tempting, the risks are too high. At crypto conferences, remove badges or any identifying items as soon as you leave the venue to blend in with the general public. Seventh, the subscriber's saving grace was having most funds on hardware wallets with multisignature. For those unfamiliar, multisignature requires multiple trusted individuals to authorize a transaction, making it significantly harder for attackers to steal funds. Hardware wallets are the number one solution, and multisignature adds an excellent layer of security. Eighth, consider having a "decoy" wallet with a small amount of crypto that you are willing to sacrifice. In an aggressive situation, it might be better to lose a small sum to save your main holdings and avoid physical harm. Finally, never answer calls from unknown numbers, especially if they claim to be from exchanges (Binance, KuCoin, Crypto.com) or hardware wallet providers (Ledger, Trezor). These entities will never ask for sensitive information like your address, seed phrase, or password over the phone. Such calls are 100% scams. The speaker concludes by acknowledging that there are many more security measures, and provides a link to a website with fifty additional tips. He stresses the importance of individual action in securing one's funds, as cryptocurrency offers financial autonomy but also demands personal responsibility for security.
