CZโs #1 Rule for Hardware Wallets
Binance Co-founder CZ said something every crypto user must know:
๐จ โYour private key should NEVER leave the hardware wallet.โ
Not for backups.
Not during updates.
Not under any condition.
๐ก๏ธ Why This Matters
๐ True hardware wallets keep keys fully offline.
๐ซ If a device can export your key, itโs a big security risk.
๐งฑ Secure chips ensure only signed transactions leave the device โ never the key.
๐ CZ warns to avoid wallets that canโt guarantee this.
๐ Why Now?
๐ More users are moving to self-custody.
โ ๏ธ But bad seed-phrase storage (cloud, phone, screenshot) destroys your security.
๐ฃ๏ธ Experts repeat: โNot your keys, not your crypto.โ
๐ก But the hidden rule: โYour key must stay inside the device forever.โ
โ What You Should Always Ask
โCan this wallet ever send my private key outside itself?โ
โ Correct answer: โNo โ impossible.โ
