Private key is defined as a string of letters and numbers known only by the owner that allows them to spend their cryptocurrency. NEVER SHARE your private key unless you want someone else to be able to take all of your money!
Your private key is very similar to your password to access your crypto. Compare a private key with a public key and address:
- Your public key is rarely ever used, but you can use it to receive cryptocurrency.
- Your address is a safer version of your public key and is what you should use to receive money.
