What’s a Crypto wallet?

Cryptocurrencies wallet store all your digital currencies. To be more specific, they store private and public keys that are to be used in sending and receiving cryptocurrencies.

A Cryptocurrency wallet is a software that allows the users to send and receive cryptocurrencies. At a time, wallets can hold multiple tokens and coins. Nonetheless, wallets only provide support to a limited number of cryptocurrencies.

A cryptocurrency wallet stores multiple and private key pairs. In order to spend your money, the keys need to be matched with a public key.

There are over fifteen hundred cryptocurrencies in the world; cryptocurrencies are not the wallets. When it comes to bitcoin and the other altcoins, the cryptocurrencies are stored decentrally and managed in a ledger that is available to the public on the network.

A private key is attached to every piece of cryptocurrency; providing a digital signature of transactions and inserting it in the public ledger, thereby spending it in the related cryptocurrency.

Wallets exist in different forms which allow users to store and access their digital currencies in different ways. However, the question that remains to haunt the cryptocurrency users is that of the security of these wallets.

Types of Wallets:

Desktop Wallets

Desktop Wallets are to be downloaded and installed on PCs and Laptops. The desktop wallets are considered to be secure unless your computer has never been connected to the internet. In case, the wallet is connected to the internet it becomes a cold wallet.

And if the computer is ever hacked or infected by a virus, the chances are that you may lose your entire money.

Paper Wallets

Paper Wallets are user-friendly wallets that ensure high-level of security. To use this, you first need to print your public and private keys. This can be used to send and receive funds to a wallet’s public address and can withdraw or send money by entering private keys or by scanning QR code displayed on the paper wallet.

Mobile Wallets

Unlike the other wallets, the mobile wallets run on smartphones via applications. These wallets work similarly to Apple Pay; you can use these wallets for shopping in stores and malls that accept cryptocurrencies as payment systems.

Online Wallets

Online Wallets are the least secured wallets in comparison with the types of wallets listed above. Also called as ‘web wallet’, these wallets can be accessed from any device and any location.

The significant advantage of storing keys on an online wallet is that it can be used to store a smaller amount of cryptocurrencies. As long as you are connected to the internet, you make cryptocurrency payments. The private keys are stored on the online wallet provider’s server. The providers store your keys and give you the access to keys by sending you the crypto code.

Some third parties have control over the keys; making the wallet vulnerable to theft and hacking.

Hardware Wallets

Hardware Wallets are probably the safest types of cryptocurrency wallets that are available to the users. The Hardware wallets stores user keys on hardware devices and are stored offline. Thereby adding an extra layer of security to users funds.

Disadvantages of using hot wallets compared to cold wallets

Before we move on to list some of the best cryptocurrency wallets, we share with you some of the disadvantages that a hot wallet possesses in comparison with the cold wallets.

difference between hot and cold wallet

The simplest way to describe hot and cold wallets is by saying the hot wallets are connected while the cold wallets are not. Often people store currencies on both the wallets as they are designated for different purposes.

So what are Hot wallets?

Hot wallets are cryptocurrency wallets that are connected to the internet. Ideally, hot wallets are more comfortable to set up, access and acknowledge more tokens. The wallets are often referred to storing your bitcoins and other cryptocurrencies in an exchange where currencies can be withdrawn instantly.

It involves a significant amount of risk when holding currencies in a hot wallet, as most of the devices are vulnerable to hackers or malware that enter into systems and steal funds. Thereby it is recommended that you don’t store a large number of currencies in a wallet that has low standards concerning security.

Cold Wallets are cryptocurrency wallets that aren’t connected to the internet. The wallets are more secure, but they don’t support or store as many cryptocurrencies as hot wallets. Since the wallets are not connected to the internet, the wallet is protected from vulnerabilities like unauthorized access and cyber attacks, whereas a system connected to the internet is prone to attacks like these.

Cold wallets are also referred to as Hardware Wallets, allowing to store keys on devices like USB( Ledger, Trezor, etc.) Often wallets are categorized into two platforms: an offline wallet containing private keys and another platform for holding the public keys.

Why you should go for a Cold Wallet instead of a Hot Wallet?

Hot Wallet providers store your keys on their servers, this makes your funds more vulnerable to technical glitches, regulations, and more specifically hackers. Whereas cold wallets are more secure because the keys are stored offline on USB devices.

To access the data, the hardware or physical wallets need to be plugged into a computer or a laptop. There is an added layer of security to the cold wallets as no one other than the owner can have access to the information associated with their crypto funds.

However, cold wallets are not free and cost about 80-90$ and do justice to their cost, in comparison with the hot wallets, which are free for the services they have to offer. If you are someone who is excited and interested in cryptocurrency investments, cold wallets are the safest wallets to go with.

Disadvantages of using a hardware wallet

Hardware wallets are relatively new, but for now, they are maintaining a good track record when compared to the wallets that are connected to the internet. However, it is essential to understand that hardware wallets are the target of high value, there are ways that in which a hardware wallet can fail to protect your cryptocurrencies. The number of risks has to be carefully considered when throwing trust in a single wallet and which one to buy.

  • Cold wallets aren’t free. The prices of a few wallets are slightly expensive, and some exceed more than $50.
  • These wallets are not ideal for quick and regular transactions.
  • Most hardware wallets don’t provide support to all the cryptocurrencies.
  • If you forget the seed keys or PIN, you may not be able to access your coins.


Most of the cryptocurrency users leave their coins on an online exchange platform. Although storing currencies on these platforms are convenient, however, cryptocurrencies are not secure.

Cryptocurrencies can be stolen and are vulnerable to attacks; this is why you need to go with hardware wallets to store all your coins.

We suggest you use either Ledger Nano S or Trezor, as they provide brilliant security and also how intuitive their user interface is. We also recommend you to purchase these hardware wallets from an authorized and reputable seller.
