🔐 What is a Private Key?
🧠 A private key is like the key to your safe.
→ Whoever holds this key can open your wallet and take all your money.
📱 In crypto:
A private key is a secret string of characters generated by the system.
It is used to access your cryptocurrency wallet (like MetaMask, Trust Wallet...).
If you lose it, no one can help you get it back.
If it is exposed, others can take all your money.
🔑 A simple example:
Crypto wallet = safe
Private key = safe key
🧨 Losing the key = consider it as losing the safe!
🚨 Important note:
✅ Write down the private key on paper → Store it in a safe place
❌ Do not take photos, do not save it on your phone, do not send it via Zalo!
🧠 In summary:
The private key keeps your money safe.
Losing it → no one can help. Being exposed → consider it as losing money.
