What is a Bitcoin wallet and why do we need it?

Bitcoin, unlike most of traditional currencies, is a digital currency. Thus, when it comes to acquiring and storing. you need a completely different approach. As Bitcoins don’t exist in any physical shape or form, they can’t technically be stored anywhere. Instead, there are private keys used to access your public Bitcoin address and sign for transactions that need to be securely stored. A combination of the recipient’s public key and your private key is what makes a Bitcoin transaction possible. Unlike physical wallets, Bitcoin wallet comes in many types.

Similarly, in the world of cryptocurrencies, we need wallets to hold our cryptocurrencies. Just like what we keep our cash money in.

Bitcoin is one of the most popular and widely used cryptocurrencies, and it requires a wallet to hold it in. Unlike physical wallets, Bitcoin wallet comes in many types.

There are several different forms of Bitcoin wallet, catering for different requirements and varying in terms of safety and security, convenience, accessibility, etc.

For understanding Bitcoin wallets, let’s take a look at something similar, email accounts.

Imagine you have your email address based on which service you are using like
This is a public address(everyone can see it, and you can share it with anyone for receiving emails). You also have a software/service like Gmail or Hotmail through which you send and receive your mails.

And you have a password to log in to your email service to send mail to others’ email IDs (others’ public addresses)But your password is confidential and private for your own use and theirs is confidential for their own use.

The software/service understands the public address ( and your password (private address)to successfully log you in and send/receive/store emails.

Similarly, for sending/receiving/storing bitcoins, we require a wallet on the Bitcoin network, which is a place for storing our public address(a place to receive bitcoins) and a private address(to send/spend bitcoins). In an even more simplified way, a wallet is a digital file which stores your bitcoins.

  • Bitcoin Address + Private Key = Bitcoin Wallet

Since the keys are offline, they are printed and secured by the owner and there is no threat of any electronic damage to bitcoins unless the printed keys are lost.
