What is a Cryptocurrency Electronic Wallet?
A cryptocurrency electronic wallet is similar to a regular bank card where your funds are stored. However, in this case, your virtual currency is stored instead of fiat money. Crypto wallets can be of different types: a special computer program, a mobile application for smartphones or tablets, or an online crypto wallet. Most cryptocurrency exchanges automatically provide an account for storing digital assets after registration.
The criteria for choosing a crypto wallet depend on many factors. The most important are reliability and the ability to securely store your private key or seed phrase (a sequence of twelve or twenty-four specific words in English that give access to your virtual currency stored in the wallet).
Just like fiat money is stored in a bank account rather than on a card, virtual currency is not stored on the wallet itself but on the blockchain. Electronic wallets exist to manage private keys conveniently and to access your funds.
By storage type, wallets are divided into hot wallets (requiring an Internet connection) and cold wallets (without a connection). Additionally, there are multi-currency wallets and single-currency wallets for one type of crypto.
Large amounts are best stored in hardware wallets. For traders who actively operate on exchanges, storing crypto directly on the platform might help avoid transaction fees.
For everyday use, mobile or desktop wallets (installed on a PC) are a good choice for sending, receiving, and managing funds. Online wallets are suitable for beginners starting to explore the crypto world, but it is better not to store large sums there.
If you’re unsure which type suits you best, you can create multiple wallets and combine them. We will discuss storage options for cryptocurrencies further below.
Structure of a Cryptocurrency Wallet
The main purpose of a crypto wallet is to assist users in managing digital assets.
To start working with virtual currencies, you need a specialized program — a cryptocurrency wallet — integrated into a hardware, software, or exchange environment. It also provides access to the blockchain system, allowing you to create and execute transactions.
A crypto wallet, regardless of its environment, is equipped with a private key and a public key.
The private key is a security key generated cryptographically from random numerical values. It cannot be decrypted or hacked. It is represented as a 16-character number and consists of 32 bytes or 256 bits. The private key is used to sign transactions, which are then sent to the network for approval before reaching the recipient.
The public key is an open code accessible to any user. It contains a combination of letters, symbols, and numbers and is necessary to receive funds into a crypto wallet.
Is Using a Crypto Wallet Secure?
The best crypto wallets are the most secure ones. In the virtual currency system, the safety of your personal account is maintained by a network of miners who validate operations and secure the system with high-speed processing algorithms. Hacking the existing level of security is theoretically possible but would require enormous computational power. For instance, a hacker aiming to commit double-spending on Bitcoin’s blockchain would need a computational power exceeding that of the entire network’s miners combined, and still would have only a chance of success after surpassing 51% of the total network power.
Custodial Wallet
A custodial crypto wallet is a program intended for transferring and storing virtual currencies. Its main characteristic is that the custodian (operator) controls users’ addresses or has access to their private keys. Additionally, users must verify their identity (KYC procedure).
Centralized exchanges typically offer built-in custodial wallets. Even though each user has an individual account and balance, the actual funds are stored in a few addresses controlled by the exchange. This makes working with trading tools easier and often fee-free for internal transfers.
Drawbacks:
The main disadvantage of custodial wallets is that the operator has access to users’ assets. Centralized custody of a large amount of crypto makes exchanges a prime target for hackers, potentially resulting in client losses. Moreover, exchanges, being legal entities, must comply with regulations and can freeze accounts or provide user information to authorities if required.
Another disadvantage is possible downtime during technical maintenance, when users may lose access to their funds temporarily.
Non-Custodial Wallet
A non-custodial crypto wallet gives users full control over their assets through personal private keys. Such programs cannot freeze or control user funds and are not responsible for asset security.
Typically, these wallets can be installed on a personal computer, phone, or browser. No identity verification is required to generate an address via a non-custodial application.
Another security guarantee is the open-source nature of these wallets, allowing independent verification of their safety.
Which Wallet is Better: Custodial or Non-Custodial?
Virtual currencies and assets used for trading or investing can be stored on custodial wallets (e.g., on exchanges). However, it is crucial to strengthen account security by enabling two-factor authentication.
Unused cryptocurrencies are better stored in personal non-custodial wallets, where only you possess the private keys.
“Hot” and “Cold” Cryptocurrency Wallets
All crypto wallets are classified as hot or cold. Beginners may prefer hot or software wallets, as they are easier to use across various platforms and devices.
Hot wallets require an Internet connection and are considered less secure and more vulnerable to hacker attacks due to their online nature. However, they are more convenient for quick transactions.
Cold wallets, such as hardware wallets, are offline devices like USB drives or Secure Element chip devices. They offer better security but are less convenient for frequent transactions.
Types of Cold Crypto Wallets
Hardware Wallets
Buying a hardware crypto wallet means purchasing a physical device that randomly generates private and public keys stored within it. These wallets are highly secure but may experience technical malfunctions, which can be mitigated by choosing a reputable manufacturer.
Hardware wallets are mainly used for long-term storage rather than daily transactions.
Software Wallets
- Desktop wallets are programs installed on PCs, giving users full control over their assets and keys. Important files (wallet.dat) must be password-protected and backed up securely.
- Mobile wallets are smartphone apps allowing users to buy and sell crypto easily, often via QR codes.
Security measures include backing up the seed phrase and protecting the wallet with strong passwords. Frequent users should choose wallets that sync with crypto exchanges.
Paper Wallets
Paper wallets involve printing key information offline, removing the risk of online hacking. However, loss or damage of the paper could result in permanent loss of access to funds.
Multi-Currency Wallets
These wallets allow holding different types of cryptocurrencies and may come as hardware, mobile, or desktop versions.
How to Choose a Cold Wallet?
- For small amounts, paper wallets are suitable.
- For large amounts, hardware wallets (crypto USB drives) offer the best security.
- For those afraid of losing a device, mobile or desktop wallets are safer.
If choosing a mobile or desktop wallet, pay attention to:
- Official developers,
- User-friendly interface,
- Strong security standards.
Regardless of the wallet type, always back up your password, private key, or seed phrase securely.
How a Hardware Crypto Wallet Works
Hardware wallets store your data offline, resembling USB drives. Some support Bluetooth connectivity. They use several protection methods like PIN codes or fingerprint scanning and generate private and public keys internally. While hacking them is virtually impossible, physically losing the device could mean losing access to your funds.
Advantages:
- Protected from hacker attacks,
- Independent from platforms,
- Portable worldwide,
- Ideal for long-term crypto investments.
Disadvantages:
- Impossible to recover if passwords or seed phrases are lost,
- Damage to the device can result in loss of assets,
- Transactions require extra time,
- Possible technical failures,
- Physical theft risks (thief cannot access funds, but you lose them too).
How to Transfer Crypto to a Cold Wallet?
There is a famous saying in the crypto world: “Not your keys, not your crypto.” This emphasizes the importance of having your private keys under your control.
Even though crypto deposited on an exchange wallet is yours, the platform controls it. Therefore, withdrawing to a personal cold wallet is preferred for long-term storage.
Example: Withdrawing from Binance to a Ledger hardware wallet.
1. Setting Up the Device as New
Turn on the Ledger device via the button near the USB port. Follow the on-screen instructions: right button to move forward, left to go back. Press both to choose “Set up as new device.”
2. Setting a PIN Code
Press both buttons to choose “Set a PIN code.” Select a 4–8 digit PIN using the left and right buttons. Confirm by pressing both buttons again.
3. Writing Down the Recovery Phrase
The device will display a 24-word recovery phrase once. Write down each word carefully on the provided sheet. Confirm the phrase by selecting the correct words one by one as prompted.
Protecting Your Crypto Assets
- In the device menu, click “Receive,” select the crypto you want to deposit, and copy the displayed address.
- Log in to your Binance account, go to “Wallet” -> “Overview,” and click “Withdraw.”
- Select the cryptocurrency and amount, paste the copied address, and confirm.
Creating an Account
- Turn on the Ledger device, open “Manager,” and install the required crypto apps.
- Click “+ Add account” to create a new crypto account and link it to the app.
After confirmation in the blockchain, your crypto will appear in the Ledger wallet balance. Double-check all information before transferring, as transactions are irreversible.
