After more than 10 years of Bitcoin’s existence, the level of awareness of its holders about how to safely store assets still remains at a rather low level. Not everyone understands what a hardware wallet is and what it is made for.
Despite numerous reports of hacking of cryptocurrency exchange wallets and various types of wallets, followed by theft of user funds, many continue to be frivolous about this problem, preferring the simplest and most vulnerable storage options.
If you are one of those who are interested in the possibility of reliable storage of the main cryptocurrency, a hardware Bitcoin wallet is perfect for this purpose. Let’s examine their principle of operation and look at some examples.
How Do Hardware Wallets Work?
A cold wallet is cryptocurrency storage that does not have a permanent connection to the Internet. In this case, we are talking about local storage of files with private keys that provide access to addresses with bitcoins on the blockchain network.
Unlike hot wallets, which allow you to make transactions at any time, a cold wallet is not intended for frequent use in asset transfer operations. For the same reason, it becomes impossible for attackers to gain remote access to them.
Most often, a cold bitcoin wallet is used to securely store large amounts that are not used for a long time in trading, investing and other activities with cryptocurrencies.
Types of Cold Wallets
Depending on the method of technical implementation of the storage process, cold wallets are divided into several categories. Most of the following options are multi-currency solutions that support bitcoin, although there are ones created exclusively for it.
- Hardware wallets are small-sized devices for storing several types of cryptocurrencies with a high level of security, the interaction with which is carried out only through computer equipment with installed native applications.
- All sorts of USB flash drives, memory cards, and portable hard drives are a budget alternative to hardware BTC wallets. To comply with all the conditions of the category of cold storage, after recording private keys, these devices are removed from computer slots and stored in safe places.
- The easiest way to create a cold wallet for bitcoin is to write down on paper the data needed to access the coins. Private keys can be written manually or printed both in the original form and in encrypted, including in the form of QR codes. Thus, a paper cold wallet is obtained, which must be stored at least in a place hidden from prying people, but best of all in a safe or a bank cell.
If you want to create a paper wallet for cryptocurrency, It is best to use special services like bitaddress.org that generate new private and public keys, for example, as a result of arbitrary user cursor movements.
