I have been exploring cryptocurrency for about 2 weeks now and I have questions about private keys. I have been reading and some people say that when someone doesn't have his private keys, it means that he does not own his coins or his coins are not in safe hands, etc. May I ask what are private keys and where can I see it? I also want to ask if what are good measures to prevent stealing of someone's coins.
Follow up question: What are these set of words that wallets give me and what are its uses? Is it good to open a safety deposit box in a bank to keep a copy of these words for whatever its use? Thank you and have a great day.
"Don't share your private keys or passwords. You have to share only your
public address to receive coins, but
never share your private keys or passwords with anyone. If you can avoid being online when you enter your private keys and passwords, that is even better."
