What is a Cryptocurrency Wallet?

A cryptocurrency wallet is a secure digital wallet used to store, send, and receive digital currencies like Bitcoin and Ethereum.

Crypto wallets keep your private keys – the passwords that give you access to your cryptocurrencies – safe and accessible, so in order to use crypto, you’ll need to have a wallet.

Some wallets are designed for a single cryptocurrency, while others may be used for many coins. They range from simple-to-use apps to more complex security solutions. 

How does a crypto wallet work?

A crypto wallet is a straightforward piece of software. The wallet program produces two keys, one public and one private, that you may use to transfer and receive crypto and manage it in various ways.

A public key can be shared with the public in order for people to send cryptocurrency to a wallet. In reality, a wallet address is just a hashed and compressed form of a public key. A private key is a mathematically connected cryptographic string of numbers and letters to a public key.

Because the public key is obtained from the private one, private and public keys come in pairs.

A wallet lets you view balances associated with an address and lets you move funds around on the blockchain as long as you are the owner of the address.

In essence, a wallet is similar to your online bank account platform, with your address serving as your account number, the blockchain serving as the bank’s ledger, and the custodian serving as your banker in the case of custodial wallets.

Types of Crypto Wallets

Cold Wallet

Keys are stored in a thumb-drive device that is kept in a safe place and only connected to a computer when you want to use your crypto. You can attach it to your computer using a cable or via bluetooth. Hardware wallets are less vulnerable to viruses or hackers, and crypto thefts from cold wallets are rare. A good choice for a cold wallet is Ledger.

Hot Wallet

Keys are stored in an app or other software. Web wallets are online services that you can access from practically any device, just like you would with your email. This makes your private keys more accessible when you want to make a transaction. The fact that you must have an internet connection to access your wallet makes it potentially risky, so look for one that is protected by two-step encryption.

Paper Wallet

Paper wallets are an antiquated form of crypto storage that is essentially a rudimentary version of a cold wallet. Keys are written on a physical medium like paper and stored in a safe place.  A QR code may be printed for both a public and private key. This lets you to use a paper wallet to transfer and receive digital cash. By utilizing a paper wallet instead of a digital wallet, you may fully avoid storing digital data about your currency.

Custodial Wallet

Some investment applications and platforms, such as cryptocurrency exchanges, enable you purchase, sell, and store your cryptocurrency using an embedded or hosted wallet, which means the wallet is stored on the site. These wallets are “custodial,” meaning that the service or exchange keeps the private keys to your cryptocurrency and, as a result, has ultimate authority over your assets.

Web3 Wallet

Web 3 wallets are non-custodial. It means you can store digital assets securely without needing a middleman, but take ultimate responsibility. They are a great way to get started with a variety of blockchain-based crypto apps, such as Decentralized Finance (DeFi), Gaming, and Non-Fungible Tokens (NFTs). For example, you can use MetaMask to access the Ethereum, Binance Smart Chain, and Pologyon networks.

What Crypto Wallet Should I Use?

Even if you have an online wallet or a custodial wallet on an exchange, investing in a cold wallet is recommended, especially if you want to keep substantial sums of cryptocurrency. However, you must weigh the benefits and drawbacks of both accessibility and security.

Using a hot wallet, which is connected to the internet, or a custodial wallet, which is tied to your online trading account, can allow you quicker access to your keys, resulting in less bother when sending or receiving cryptocurrency.

Using a cold wallet to store your cryptocurrency is less sensitive to hackers, but it makes trading a bit more difficult.

Bottom Line

Wallets for cryptocurrencies are a wise investment. Experts propose that customers invest in many types of wallets to make the most of their capabilities and keep their valuables safe. This is especially important when working with many types of cryptocurrencies with varying characteristics and values.


Investing is always a risk but investing in cryptocurrency is an even higher risk as they are VERY volatile, so if you decide to invest in crypto, you should be prepared that you might lose all your money
