 TITLE: What Is a Cryptocurrency Wallet? CONTENT: Keep Your Keys Safe\n-------------------\nThere's a popular phrase in the cryptocurrency world: \"Not your keys, not your coins.\" In short, whoever controls a private key controls the cryptocurrency associated with it. Never share your private key—even if someone promises you free coins or contacts you to say there's something wrong with your account (it's a scam).\nIf you share or someone steals your private key, they can transfer your funds, and there might not be a way to get them back. Or, if you lose your private key, you might not be able to access the cryptocurrency again. END
