Before a business trip, he had his wife transfer funds. After landing, the balance of 3,000,000 USDT shockingly went to zero! After reporting to the police, he learned that it was a family member's action and was classified as a civil dispute. His wife was devastated, claiming she only pasted the mnemonic phrase. The truth is alarming, and the issue lies in that 'pasting'.
He stored the mnemonic phrase in WeChat, his wife's old Android phone had not changed its password for years, the WiFi had not been changed for three years, and there was a 'financial assistant' plugin. This 'death combination' allowed hackers to listen in on the clipboard in real time. The moment the mnemonic phrase was pasted, the gateway to wealth opened, and money was instantly transferred with no transaction record.
The cryptocurrency world continuously guards against such painful lessons, with three crucial rules embedded in its DNA.
Rule One: Mnemonic phrase, keep it extremely secret
Mnemonic phrases are like property certificates and safe passwords; write them on a metal plate and store them well. Don’t screenshot and send them via WeChat, not even to family. WeChat cache, photo albums, and cloud synchronization all leave traces; 70% of theft cases originate from screenshots and transmission.
Rule Two: Operating the wallet, keep the device 'clean'
Prepare an old phone, only install the official wallet APP, don’t connect to public WiFi, and don’t install 'free coins' or 'market plugins'. These plugins can read the clipboard, and if hackers listen for 6 months, they will copy your mnemonic phrase.
Rule Three: Family operations, exercise extreme caution
Don’t think that teaching a few words to family means they can operate the wallet; authorization and verification can easily lead to phishing links. If you really want to help, do it via video while watching, and verify the last four digits of the address after transferring coins.
Hackers clear logs on servers after 72 hours; if they find money without evidence, it’s already gone. Check your mnemonic phrase storage, device plugins, and family awareness immediately.
Surviving in the crypto world, monitoring K-lines is just the basics; preventing risks is key. Be meticulous with assets, and you’ll feel more secure against hackers! If you want to safely recover and double your investment, remember these rules!
