Crypto Wallet: Hot and Cold Wallet in 2023

Where their priceless digital assets are held is one of the first queries that new cryptocurrency users have. Due to the wide range of solutions available on the market, this problem may be challenging and perplexing. Furthermore, failing to implement adequate security measures may result in financial loss with no hope of compensation.

Users have a choice of two fundamental storage options: hot wallets or cold wallets. One style of wallet might be better for you than the other depending on your situation and at certain times.

I. What is a Crypto Wallet?

Crypto Wallet

A crypto wallet is a piece of software designed to store cryptocurrencies. Although it is called a “wallet”, it is not a literal wallet.

Public and private keys used to uniquely identify each wallet are stored in cryptographic wallets. The program creates information that users can use to manage their own digital assets, including sending and receiving cryptocurrency through blockchain transactions. Users are required to include a digital signature, which is algorithmically created with the aid of a private key, while sending cryptocurrency. The signature will be invalid if the supplied key is incorrect.

A public key is an address that you can freely share with other network users in order to receive money, but a private key is different because it gives third parties access to your wallet.

A private key is a string of symbols that acts as a personal password for cryptocurrency. You will lose access to your crypto wallet and all of the funds contained in it if you misplace your private key, and there is no way to retrieve it back. Cryptocurrency owners won’t be able to get assistance from a third party to regain access to centralized payment services like banks.

For your money to be secure, you must safeguard your private key. You have two options: either assume complete responsibility for your actions and exercise all due prudence, or commit your money to a centralized agency. This is a crucial feature that separates cold wallets from hot wallets.

II. What Is a Hot Wallet?

Hot wallet is an online wallet used to store and manage cryptocurrencies. Hot wallets were the only choice for early cryptocurrency adopters and aficionados when Bitcoin was initially introduced.

Hot wallets with crypto storage are made available online through specialized platforms. In this scenario, the user must also provide the service access to their private key. For the benefit of users, many cryptocurrency exchanges offer hot wallets. Members of the platform will automatically acquire a wallet once they sign up.

III. Category of hot wallets

The following wallets fall under this category:

  • Desktop wallet (e.g. Electrum or Coinbase)
  • Mobile wallet (e.g. Trust Wallet or Edge).
  • Web wallet (e.g. or MyEtherWallet).
  • Browser wallet (e.g. Jaxx or Metamask).

Hot wallets may be non-custodial or custodial depending on the service’s policy. Non-custodial wallets give users control over their private keys. In contrast to a custodial wallet, the private keys are controlled by a third party.

This leads to the following question: are hot wallets safe? Generally yes, but there is still the possibility of being hacked which could cost users money. Therefore, for long-term investors who are holding their coins, hot wallets may not be the best choice.

IV. Other information about hot wallets 

1. When Should I Use a Hot Wallet?

Despite the reduced security, there are some cases where hot wallets are the best option, so there is no reason to give them up. Here are some of the most common use cases:

  • Small transactions: use a hot wallet if you need to send a small amount of money to other users.
  • When you need quick access: hot wallets are convenient for instant payments.
  • When you prioritize convenience: hot wallets are a good choice for cross-platform access.

2. Advantages of Hot Wallet

In many ways, the convenience of using a hot wallet is undisputed. With that said, hot wallets have the following advantages:

  • Easy to set up: Online wallets can be created in minutes.
  • Instant access to cryptocurrencies: This feature makes the wallet ideal for frequent transactions.
  • User-friendly interface: Their function is obvious even to a novice.
  • Multi-level security: Reputable services do their best to protect hot wallets from cyber attacks and implement security best practices like multi-factor authentication and other extra layers of protection.
  • Multiple backup options: Hot wallets often provide users with multiple methods of recovering their funds, thus protecting them from the risk of accidentally losing their private keys.
  • Ability to accept multiple tokens: This feature makes the hot wallet suitable for traders and investors with diverse portfolios.
  • Free calculation: Hot wallets are provided for free while hardware wallets can be quite expensive
  • Insurance: Online services like Coinbase often have their own insurance funds that can reimburse users in the event of a hack.

3. Disadvantages of Hot Wallet

While hot wallets are the preferred choice of millions of users due to their convenience, this option has some serious drawbacks:

  • Less protection: Despite multiple levels of security, even the top crypto exchanges are vulnerable to malware and hacks.
  • Funds are centrally stored: This feature leads to 2 serious drawbacks. First, centralized servers often fall victim to cybercrime. Second, huge centralized servers can take longer to process transactions when there are many users.
  • The lack of access to your private keys: When holding coins in a hot wallet, users often do not have access to their private keys, and therefore cannot fully control the digital assets stored in the wallet.

V. What Is Cold Wallet?

The main difference between a cold wallet and a hot wallet is that it is not connected to the Internet. This feature makes cold wallets the safest storage options as it makes hacking and malware attacks inaccessible. Connection is only required when making transactions.

Cold wallets often take the shape of a physical flash drive that must be connected to a computer in order to access cash. Can you trust cold wallets? If we’re referring to hacking assaults, the answer is unambiguously yes. Because transactions are signed inside the device itself, it is almost impossible to steal money from a cold wallet even when it is linked to the Internet. If the thief has physical access to both the gadget and the private key, it may still be taken. This calls for the safest possible storage of cold wallets.

Cold wallets are generally applied to store digital assets on a long-term basis. It is a reliable and secure solution for those who move their cryptocurrencies frequently. Therefore, it is best for long-term investors to use this vehicle to store crypto funds.

VI. Category of cold wallets

The two most popular types of cold wallets include hardware wallets and paper wallets.

Hardware wallets are physical devices specifically designed to hold public and private keys in digital form. Some popular hardware wallets are offered in the market such as Ledger Nano X, Ledger Nano S, Trezor, KeepKey and others. Their prices usually range from $60 to $200.

If you are looking for a free alternative, a paper wallet could be the solution. To use a paper wallet, you should print out a piece of paper and keep it in a safe place. In terms of security, it is now considered an outdated method as it is unreliable compared to other options. Paper can be easily damaged. Besides, you need to be tech-savvy to properly use this storage method.

Some people use spare mobile devices as cold storage devices and only enable them for transactions. During the transaction, the phone must be connected to the main phone via Wifi or Bluetooth to transfer funds from it to the hot wallet. Once the transaction is complete, the backup phone will be disconnected and turned off to keep your digital assets safe. Old laptops can also apply this method.

VII. Which Crypto Wallets are suitable for (Project Token)?

1. Advantages of Cold Wallet

Security is the main feature that outperforms its hot wallet cousin. It is not connected to the internet, so only the wallet owner has access to the data it contains. With that said, the main benefits of cold wallets include:

  • Resistance to hacking attacks: Basically, hardware wallets cannot be hacked.
  • Limited USB connections: This feature is built in to protect private keys even if your mobile device or computer is compromised.
  • Regenerate private key: With hardware wallets, keyphrases allow you to recover your assets and regenerate private keys even if the wallet is lost. What’s more, it can even restore transaction history.

2. Disadvantages of Cold Wallet

Despite their high security, cold wallets have many disadvantages that make them not widely accepted.

Price: As mentioned above, cold wallets are quite expensive. The most affordable options cost around $60, while premium models can go up to $500 a piece.

  • The difficulty in using: Trading crypto from cold wallets requires additional steps that can complicate the process.
  • Not suitable for traders: Using cold wallets for trading can be very risky due to the highly volatile prices. Since cold wallet withdrawals are not instantaneous, prices may change in the process and result in unprofitable trades. Therefore, hot wallets are much more suitable for this purpose.
  • Difficulty in installation: Hardware wallets are often used by experienced crypto investors with a technical background while beginners may encounter problems setting up a wallet for the first time.
  • Inconvenience: It is necessary to plug the cold wallet into your PC every time you make a transaction.

Although the cons outweigh the advantages, cold wallets are still the best choice for long-term crypto storage due to the enhanced level of security they provide.


The choice of wallet depends on the specific circumstances and activities of the cryptocurrency owner.  A hot wallet is the perfect option for you if you’re a crypto newbie looking for convenience, a trader who wants quick access to your money, or if you just regularly pay with cryptocurrency.

However, if you are an investor interested in long-term crypto storage and value security above all else, a cold wallet is probably a better choice because of its enhanced level of security.

To select the wallet that best meets your needs, it is crucial to thoroughly consider your cryptocurrency ambitions.
