A cryptocurrency wallet is a piece of software that keeps track of the hidden keys used to sign electronically for shared ledgers cryptocurrency transactions.

Cryptocurrencies are the digital currency that can be sent and obtained through the advanced blockchain technology, using a wallet address which holds the private and public keys, without the intervention of any third parties.

This is why for each cryptocurrency a new wallet must be developed. 

A Bitcoin can’t be sent to an Ethereum wallet, for example. 

You’re going to do that? 

Otherwise you run the risk of losing your cryptocurrencies.

A hardware wallet covers just as well as a few hundred million in bitcoin / crypto.

What is a Crypto Wallet? 

You directly transfer ownership of the coins to the address of your wallet when someone sends you cryptocoins. 

The private key stored in your wallet must suit the public address to which the currency is issued to complete the transaction. 

And if the public and private keys match, your balance will go up, while the sender’s will go down accordingly.

A wallet is a program for sending, receiving, monitoring and storing your crypto-assets. 

A wallet takes shape from either a desktop app, a mobile app, or a hardware wallet.

When you’re talking about the cryptographic keys associated with your cryptocurrency wallet, you’re referring to a very long string of machine-generated numbers and letters that lock and unlock access to your cryptocurrency set and generate your wallet’s addresses.

In addition to storing your public and private keys, crypto wallets integrate with different currency blockchains to allow you to check your balance and send and receive funds.

How a Cryptocurrency Wallet Works

First off, compared to your physical wallet, digital wallets are quite different. 

Digital wallets store private and public keys instead of storing money.

When someone transfers cryptocurrency to someone else, they sign off coin ownership to the wallet address of the recipient. 

To enable the recipient to spend these coins, they must have the private key that matches the currency’s public address. 

The digital wallet balance increases if public and private keys match. There is no real exchange of coins.

At first glance, it turns out to be intimidating before you figure out that it is sufficiently versatile to write down, print on paper, type a file, convert to image form or even memorize.

The wallet also contains an address, an alphanumeric identifier generated on the basis of public and private keys. 

In essence, such an address is a specific “location” on the blockchain to which coins can be sent.

It ensures that to receive funds, you can share your address with others, but you should never reveal your private key to anyone.

Features of Crypto Wallet

While selecting a cryptocurrency wallet, the most important feature you can look for is whether or not it supports the currencies you want to use. 

Bitcoin is a default, but not every cryptocurrency wallet and not every cryptocurrency wallet checked in this review roundup yet supports even this currency. 

Today there are literally dozens of cryptocurrencies, with more available

Hot and cold wallets – which is more secure?

There are two main types of crypto wallets: hardware and software (also known as cold and hot storage wallets, respectively). 

Hot Storage

Hot storage refers to the internet-connected storage type. 

Hot storage, connected to the Internet, enables users to access funds easily and quickly.

In daily transactions, it is helpful. 

But it also has some drawbacks. 

It’s more vulnerable to cybercrime and hacking. 

If the private key is lost, the access to coins will no longer be possible. 

Even, if you stole the private key

Cold Storage

Cold storage refers to storage types that are not connected to the Internet. 

It is also referred to as offline space. 

Cold storage provides a higher security level relative to cold storage. 

In comparison to hot wallets, it is useful for long-term storage. 

But, at the expense of convenience, the lower level of security is offered.

It’s not ideal for everyday transactions. 

Types of Wallets

What is a paper wallet?

It is an offline way to store digital coins to keep it simple. And it might just be a piece of paper printed with your private and public keys. You can also put it in a safe place!

The paper wallet means you’re going to get your cryptocurrency’s private key. 

You must type the complete key to make the transaction.

 I know this sound is strange and old-fashioned, but it makes paper wallet one of the safest ways to store cryptocurrency due to its operation.

What is a hardware wallet?

A USD drive or a dongle may take shape, sometimes with a screen. 

And just plug it into your PC to make a transition then enter your pin. Just make sure that you’re not losing it!

The two Bitcoin and cryptocurrency hardware wallets that are most common and best are:

In a secure offline environment on the hardware wallet, your all-important private keys are maintained, fully protected even if the device is plugged into a malware-infected computer.

What is a mobile wallet?

You can use mobile wallets on a mobile device, as the name suggests, and you can access your wallet on the move. 

One of the great things about mobile wallets is that they often provide more features than purely internet-based wallets. 

That’s not to say without threats they don’t come.

What is a desktop wallet?

Desktop wallets are among the safer wallets for cryptocurrency; however, this depends on how committed you are to keep up with the latest online security measures.

Download and install mobile wallets on your computer. 

If confidentiality is your main concern, it is a good option to use the Bitcoin core wallet as it does not rely on information from third parties.

What is a Hosted wallets?

Cryptocurrency is the simplest but most risky way to store.

The client trusts his money to a third party, but as if it were a bank, he receives no protection.

The server can be compromised by the administrators themselves or remotely. Secure wallet supply by private keys.

If such a key is not only known to the fund holder but also to a third party, then two owners already exist.

What is a Decentralized Wallet?

You hold the keys of your wallet, enabling you to communicate and create a transaction anywhere with anyone. 

You then hold your keys again, which means that you better protect the hell out of them or face a potentially really bad day.

Are there any transaction fees?

There is no fee-free Bitcoin wallet. If you want your Bitcoin transaction to be successful, you should pay a fee. 

Bitcoin miners are charged this fee for providing this service. 

There is therefore no such thing as a Bitcoin wallet that has no transaction fees. 

You can, however, configure your Bitcoin wallet to transfer Bitcoin with low transaction fees or the lowest fees possible

Are Cryptocurrency Wallets Secure?

There is no such thing as a “good cryptocurrency wallet” one-size-fits-all. 

The best wallet for you will be one that suits your needs, so if protection is your number one concern, you are likely to end up choosing a different wallet for someone who wants to access their coins quickly and easily.


The cryptocurrency environment is constantly evolving and security systems are being developed, so you should take all the necessary security measures and stay up-to-date with the latest security improvements and updates to keep your Bitcoin or any other cryptocurrency wallet safe from unwanted parties.

The first camp is made up of speculators who are risk-friendly and are therefore not searching for a cryptocurrency wallet that asks a lot of questions. 

The second camp consists of conservative investors interested in fewer digital assets and want a safe environment more similar to our regulated banking industry.

While there is no such thing as an ‘ unhackable ‘ device, you can take important measures to drastically reduce the chances of compromise.

They are one of the basic infrastructure pieces that enable blockchain networks to send and receive funds. 

Each type of wallet has its advantages and disadvantages, so understanding how they work before moving your funds is crucial.
