A paper wallet is a physical document that contains your cryptocurrency private and public keys. It allows you to store your digital assets offline, making it less vulnerable to online hacks. Typically, a paper wallet is generated using a secure website, and it prints out the keys in the form of QR codes for easy scanning. Using a paper wallet is a simple way to keep your cryptocurrency safe, especially for long-term storage. However, it’s important to keep the paper in a secure place, as losing it means losing access to your digital assets. Always create paper wallets in a secure environment to avoid exposure to malware.
