Varieties of cold bitcoin wallets

Since the emergence of Bitcoin on the market there have been many storages, which differ not only in the way of access, but also in characteristics. The user himself chooses the option that suits him in terms of the set of functions, interface and degree of security.

Hardware wallet

This is a carrier in the form of a USB flash drive. Private files are created inside a secure environment. It is considered a safe way to interact with digital assets because of the use of crack-resistant cryptography.

Hardware cold BTC wallets are more commonly used to store large amounts. It is not very convenient to conduct transactions on a regular basis: you need to be connected to a computer.

Due to the risk of software failure of the device and loss of all information on it, the user should carefully choose the manufacturer. In order not to lose all the funds, you should be careful.

Paper wallet

This is a printed sheet with public and private keys that are available only to the owner. The advantage of this method is complete autonomy without connection to the Internet. The data can be easily copied. Duplicates can be stored in different places to reduce the risk of losing access to assets due to mechanical damage to the paper wallet.

In 2023, this method is not very popular. Users favor more technologically advanced storage.

Removable storage devices

As a cold Bitcoin wallet, you can use an ordinary USB flash drive or a portable hard disk. After installing the program on a PC, all files necessary to identify the owner are transferred to external devices. Without a connection to a computer, it will not be possible to sign a transaction to send cryptocurrency.

Desktop wallets

These are storages in the form of software installed on the user’s PC. They come in two types:

• “Thick ” – you need to download the entire blockchain to your hard drive and synchronize it. This requires more than 500 gigabytes of free space.
• “Thin ” – no download of the entire registry is needed. The program works faster.

How to create a wallet

To work with cryptocurrency, you need special software that will interact with records in the blockchain, displaying the balance of funds and sending coins to other recipients. Step-by-step instructions for installing the program on your computer on the example of Electrum Wallet:

1. Download the installation file from the official website.
2. Choose the way of connection to the server (automatic or manual).

3. Come up with a name for the wallet.

   

   Enter the name of the cryptocurrency account
4. Create and save a seed phrase.

   

   Mnemonic set of words
5. Set login password.

Best cold Bitcoin wallets

Secure and simple cryptocurrency storage options range from desktop programs to hardware devices that protect your data from hacking.

How to choose the right one

The user proceeds from their own objectives for a cold wallet, with parameters of convenience and security. All of them have their own strengths and weaknesses.

Other options for storing BTC

The development of the cryptocurrency market places new demands on the protection of assets and user data. There are methods that are not based on a complex password for the private key. At the same time, they increase security without losing usability.

Multi-signature

Blockchain technology allows participants in a transaction to make a joint decision to send coins using unique keys. The security of this method is achieved by storing signatures on different devices, such as a PC and a phone. If attackers gain access to one of them, they will not be able to withdraw funds without the second one.

The Electrum program can generate up to 15 multi-signatures for a single address. The bitcoin blockchain has a partial validation feature – for example, 6 versions are issued, but 4 out of 6 in any configuration are enough to send a transaction. This simplifies the process of managing cryptocurrency with a large number of interested participants.

Fragmentation of private keys

Separating the signature with cryptographic methods provides additional protection. Any part individually cannot be used to send coins, and losing a few of them will not result in loss of access to the private key. If the signature is split into 5 parts, it will only take 3 fragments to restore the integrity of the data.

Smart banknotes

This is a new form of cryptocurrency storage where the paper contains a contactless chip. They can be used to make physical transactions, transferring smart banknotes like fiat money. At the same time, anonymity and no fees for moving the note on the blockchain are preserved. Tangem banknotes are one such project. The denomination of each corresponds to the amount of funds in the distributed ledger.

Physical coins

This is an object with a private key to an account that already holds a certain amount of cryptocurrency. The most valuable coin has a face value of 1,000 BTC or $40 million at the exchange rate as of February 2022.

The first producer was a member of the cryptocurrency community nicknamed Casascius. His nickname is a noun for such coins. Each of them contained a private key hidden behind a holography. It could not be read or scanned without damaging the sticker. Once cashed in, the coin was a souvenir.

Ensuring security

Cryptocurrency has a material value and is an object of close attention of intruders. To preserve access to the account, it is worth observing the following recommendations:

• Regularly update software, antivirus and firewalls.
• Keep sensitive data separate.
• Use 2-factor authentication.
• Back up private keys on a regular basis.

Summary

A cold cryptocurrency wallet is suitable for storing large amounts of money safely. Control over sensitive data is centered in the hands of the owner. When the user follows the guidelines to protect their property, the risk of unauthorized access to the wallet and cryptocurrency is reduced.

In 2023, there are many digital vaults available in the market. But hardware devices are considered the most reliable. Despite the high price, they are popular among crypto investors. Standalone devices additionally protect private keys with cryptography. Transaction signing takes place in a closed environment. If you combine secure physical storage with key segmentation or multi-signature, you can make a cold wallet with a high level of security for digital assets without spending a lot of money.
