A serious cryptocurrency-related crime case in France has drawn attention. On the night of January 8th, five criminals broke into a family residence in La Chapelle-Saint-Aubin, Sarthe Province (near Le Mans), and kidnapped the entire family. Their clear goal was to force the homeowner to hand over the private keys to their crypto assets. This incident once again serves as a wake-up call: individuals holding digital assets need to be especially vigilant about personal safety risks. Criminals target individuals and families holding cryptocurrencies with malicious and direct methods. How to strike a balance between protecting assets and ensuring personal safety has become a serious consideration for every crypto asset holder.
