The value of cryptocurrencies fluctuates dramatically. A decrease in value or a total loss is conceivable at any time. The failure of data and passwords might potentially result in a total loss.

If you’ve dabbled in the realm of Bitcoin, you’ve come across the notion of crypto wallets and private and public keys. But what are they exactly?

This post will explain the distinctions between private and public Bitcoin keys and how they may help you send and receive payments safely.

What is a crypto wallet?

Using a crypto wallet, you may transfer, receive, examine, and spend bitcoin. The wallet also stores your keys (both private and public), allowing you secure access to any cryptocurrency you hold.

There are two types of crypto wallets: essential hosted wallets, in which a platform manages your private key for you, and non-custodial wallets, in which you control your private keys with no third-party participation. There are also hardware wallets, which keep your keys offline and are considered more secure by some. They all have one thing in common: they’re used to store your crypto keys.

What is a private key?

A private key is a security code that allows the possessor to conduct bitcoin transactions and demonstrate ownership of their assets. Bitcoin keys, in particular, have a 256-bit string that is shown as a mix of letters and numbers. It’s kept in your crypto wallet, allowing you to access your Bitcoin anytime.

Private keys and the risk of loss or theft

Keep in mind that if someone obtains your private key, they essentially acquire access to your Bitcoin holdings, putting your cryptocurrency in danger. The same is true if you lose your private key—if you can’t access it for any reason, you won’t be able to access your money.

The hazards of misplacing or losing your private key cannot be overstated, and you should think about them carefully before diving into bitcoin. Regulations governing the usage and storage of private keys are still being developed; for example, in Germany, the storage of private keys for consumers is a regulated financial service.

What is a public key?

Unlike a private key, a public key is intended to be shared with others so that they may transfer your cryptocurrency. It is associated with the owner’s private key, which is required to “unlock” the public key. Because Bitcoin addresses are compressed copies of the public key, they are sometimes used for transactions instead.

Consider the public and private keys, address, and home keys. People will need your address to visit, but they will only be allowed to enter with your home keys.

What is a Bitcoin address?

A Bitcoin address is a 26-35 character long unique string of numbers and letters that identifies where a Bitcoin payment has been received. If you want to utilize a Bitcoin address in a transaction, you can generate one from your crypto wallet. For security purposes, experts advise creating a new Bitcoin address for each transaction.

Is a Bitcoin address the same as a Bitcoin private key?

Certainly not. It would help if you never revealed your Bitcoin private key, but you may provide your Bitcoin address to anyone who wishes to send you bitcoin. Consider your bitcoin address a hashed version of your bitcoin public key for more straightforward usage in transactions.

How to use a public key to send Bitcoin

If you want to pay someone using Bitcoin, the method is quite simple:

Check that you have enough Bitcoin in your wallet to cover the amount you wish to transfer and that you’ve chosen the correct currency.

Obtain the recipient’s Bitcoin public key or address and enter it into your wallet’s “Recipient” box. (Be aware that different wallets and systems may use somewhat different terminology.)

Make sure you’ve typed in the proper public key. If you provide the incorrect public key, your bitcoin will be transferred to someone else, and you will most likely be unable to recover it.

Enter the amount you want to send.

You’re done when you click “Send.”

How to use a public key to receive Bitcoin

If you’re hoping to get Bitcoin, you’ll need to perform the following:

To access your public key, open your cryptocurrency wallet and click “Receive” (the specific language used may change depending on your wallet).

Give the sender your public key.

Put your feet up and wait for the bitcoins to arrive in your wallet.

How to keep your private key safe

As previously said, securing your private key is the most crucial aspect of ensuring no one else has access to your bitcoin. Never give out your private key to anyone. Remember that other individuals require your public key or Bitcoin address for transactions.

If at all feasible, keep your private key offline rather than on a device that may be accessible over the internet. Consider hardware wallets as an extra safe offline storage method if you’re worried about security. The benefit is that they cannot be hacked because you are not handing your keys to a third party.

Backing up your private keys is intelligent in case you lose them. The crypto wallet you choose will determine the backup options accessible to you. There are three primary methods for backing up your private key:

+ A seed phrase is a phrase made up of 9–24 ordinary words.

+ A backup wallet file

+ Keeping a duplicate of the private key in a secure location

What happens if I lose my private key?

Unfortunately, unless you’ve backed up your private key, there’s typically no way to recover it if you’ve lost it. In other words, losing your private key will also lose the Bitcoin linked with it.
