A wallet address is like a receiving account number—it can be shared publicly. A private key is like a signature right: it proves that you have the authority to transfer the assets, and it must never be disclosed. A recovery phrase (mnemonic) is usually a backup generated for the wallet’s private key system; once it leaks, the entire wallet could be taken over. Exchange account passwords are also not the same as private keys. Remember this principle: an address can be shared, but private keys and recovery phrases must be kept offline. Anyone who asks for your recovery phrase, promises to help you “verify your wallet,” or offers to “sync your assets” should be treated with extreme caution. Once a blockchain transfer is signed and confirmed, it often can’t be undone. Developing good security habits matters more than chasing price increases.
