hello steemit, I'm going to tell you about protecting your cryptocurrency. Your digital currency is not secured in exchanges & online wallets. You are at a instant risk of loosing your coins.

This is where paper wallets come in, a paper wallet is an offline wallet which uses a 256-bit number as a private key to secure your cryptocurrency. You can save your ton of cryptocurrency in these wallets. Paper wallets are made out of paper, on which your key will be printed and stored securely. You also have to perform certain precautions to secure your currencies in paper wallets.
