For the utmost in security, paper crypto wallets might be your best bet. They take all the action off your computer or smartphone, printing your public and private keys on a piece of paper, which thereby serves as your wallet. However, what sounds easy at first can get downright complicated. For starters, paper wallets oblige you to create your own public/private keys. For that, you’ll need a key generator. You’ll also need a software wallet so others can send money to your public key, which usually takes the form of a QR code on your paper wallet. Also, if you want to send money from your paper wallet to someone else, you need to first send it to a software wallet. Hence, the paper wallet–while arguably the safest – is primarily for advanced users only.
