How to Make a Paper Bitcoin Wallet
One of the most popular options for keeping your bitcoins safe is something called a paper wallet. Here wij explain how to transfer all those digital coins into a physical paper form using just a printer.
Note that te this guide we’ll be talking about bitcoin. However, the basic concepts apply to any other cryptocurrency, for example, litecoin.
What is a wallet and why do I need one?
A bitcoin wallet consists of two ‘keys’. The one you’ll already likely be familiar with is the public key, which is your wallet address and is how other people send bitcoins to you.
The other part of your bitcoin wallet is the private key. It is this that enables you to send bitcoins to other people.
The combination of the recipient’s public key and your private key is what makes a cryptocurrency transaction possible.
It is significant to understand that, if anyone else obtains the private key of your wallet, they can withdraw your funds – this is why it’s absolutely essential that nobody else detects it.
So, if you keep your coins te either an online wallet, or a hard-drive-based software wallet, you are vulnerable to attacks by hackers or malware that can loom your keystrokes.
Furthermore, a stolen PC or a hard-drive crash could also see you flapping bye-bye to your digital treasure.
Used with care, a paper wallet can protect you from thesis possibilities.
What is a paper wallet?
A paper wallet is a document that contains copies of the public and private keys that make up a wallet. Often it will have QR codes, so that you can quickly scan them and add the keys into a software wallet to make a transaction.
The benefit of a paper wallet is that the keys are not stored digitally anywhere, and are therefore not subject to cyber-attacks or hardware failures.
The disadvantage of a paper wallet is that paper and ink can degrade, and paper is relatively fragile – it’s undoubtedly worth keeping well away from fire and water for demonstrable reasons.
Furthermore, if you lose a paper wallet, you’ll never be able to access the bitcoins sent to its address.
