Understanding the specifics of blockchain technologies is difficult for those not caught up in the crypto fever. This makes it easy to fall prey to various scams. I recall a married couple buying metal bitcoins at a city market, highlighting the tangible aspect of the digital world.

Cryptocurrency is not static on the computers of its owners, but rather exists in the form of a distributed records registry (blockchain) stored by many people. However, accessing the blockchain can be challenging. One option is a crypto wallet, an access terminal for confirming crypt transactions and allowing transfers and exchanges between different cryptocurrencies.
It is thought that Satoshi Nakamoto, the anonymous creator of bitcoin, was involved in the development of the first bitcoin wallet. This evolved into Bitcoin Core, still in use today but relatively inconvenient as it requires downloading the entire data chain to the computer.
Crypto wallets can be either custodial (registered with a third-party service) or non-custodial (keys and passwords are only held by the owner). Non-custodial wallets are more secure but require careful management. Wallets can also be hot (used on a PC) or cold (stored on a hardware device), with hardware wallets considered more reliable for long-term storage.
Hardware wallets have no permanent connection to the internet and can be connected to any computer for access. However, they need to be purchased, unlike other types of wallets which can be used for free. There is an impressive range of hardware wallets available, with Trezor, Ledger, SafePal S1, and Tangem being some of the most interesting devices.
Trezor One is an affordable model recommended for beginners and supports a variety of operating systems. It comes with two cables of different lengths, stickers, and a form for code words. Ledger is considered one of the leaders in its segment, offering a variety of models with good protection and multicurrency support. SafePal S1 is a Chinese device that supports about 30,000 types of crypto assets but has a fragile material build.
Tangem offers a hardware wallet for over 4,000 different cryptocurrencies, with support for DeFi systems and a higher level of security certification than competitor devices. Their Tangem Note is similar but supports only one cryptocurrency.
Hot wallets are a free software solution installed on a PC or smartphone that require a constant internet connection, making them more vulnerable to attacks. It is recommended to choose well-known solutions and download them from reliable sources.
In my opinion, I believe that crypto wallets may have negative intentions. However, an alternative solution is to construct a custom system unit using miscellaneous parts with at least a terabyte HDD or SSD, install Linux and the native Bitcoin Core, synchronize the blockchain for a few days, and continuously use it while keeping the blockchain updated.
This method is considered to be the most secure and also beneficial for the network by having numerous full nodes. It would be interesting to know if there are any comprehensive video tutorials available on properly utilizing the main client, including importing and exporting keys. Additionally, it's crucial to stay aware of potential risks and to always prioritize security when dealing with cryptocurrencies.
Crypto wallets that operate through software can be accessed via a web browser or by installing an application on a computer or smartphone. While some developers store user information and transaction data on their servers, many allow for downloaded storage on the wallet owner's device. These wallets are considered "hot" because they rely on network connectivity and are more susceptible to cyber attacks. Due to security concerns, it is recommended to avoid storing large sums of funds on these types of wallets.
One of the best software crypto wallets available is the Trust Wallet, which is ideal for working with Binance exchange coins and other currencies. The wallet offers several security features, including two-factor authentication, Google authorization, SMS or email verification, and primarily stores the currency on cold storage servers for maximum protection.
Although there is no fee for using the wallet or exchanging currency, a percentage is charged on blockchain network transactions. Trust Wallet also allows for easy and direct cryptocurrency exchanges without the need for third-party platforms. Its Wallet Connect function smoothly links the wallet to integrated sites, enabling users to log in and confirm transactions promptly.
Additionally, Trust Wallet offers an option to buy cryptocurrencies directly through the app via MoonPay and Simplex services. Unfortunately, the service operates exclusively through mobile apps on Android or iOS and is not available on desktop computers. As with any type of crypto wallet, it is vital to remain vigilant and prioritize safety measures for secure transactions.
Hi,
Hardware wallets are a good solution up to a point. They are relatively easy to modify and compromise the batch before selling. To do such a manipulation with a computer is a difficult task. And it is not known whether a specific laptop will be used to work with cryptocurrency. But as for a hardware wallet, you can be sure that sooner or later it will be used to store cryptocurrency. Manufacturers of hardware wallets are looking for ways to solve this problem - for example, apply security stickers. But there are dozens of ways to overcome this.
However, it should be noted that Ledger and Trezor devices are indeed designed with security in mind.
There are two main varieties: USB wallets and Bluetooth wallets. USB wallets, like the Ledger Nano S, require you to plug them into a computer for transactions. On the other hand, Bluetooth wallets, like the Ledger Nano X, can connect to your smartphone, offering more convenience but also potentially exposing you to additional risks, depending on your phone's security.
When selecting a hardware wallet, one must consider their cryptocurrency usage. Some wallets support a wide variety of coins, while others are designed for specific cryptocurrencies. It's important to choose a wallet that supports all the coins you plan to hold or trade. This ensures that you won't have to manage multiple wallets, which can be cumbersome and confusing.
Another essential aspect is security features. Most reputable hardware wallets use secure elements, similar to those found in credit cards, to prevent unauthorized access. Look for features like passphrase protection and two-factor authentication. These layers of security can significantly minimize risks.
Backup options are equally important. When you set up a hardware wallet, it often generates a recovery seed—a set of 12 to 24 words. This seed acts as your backup. If your device is lost, stolen, or damaged, you can restore your wallet using this seed. It's crucial to write this seed down and store it in a secure location, away from potential threats.
Additionally, it's vital to maintain a regular check on firmware updates. Manufacturers frequently release updates to fix vulnerabilities and enhance functionality. Always ensure you download these updates from the official website, as malicious entities can create fake updates to steal your information.
Finally, remember to always treat your hardware wallet like cash. Keep it in a safe place and never share your PIN or recovery seed with anyone. Be cautious of phishing attempts that can trick you into giving away your information.
Using a hardware wallet is one of the best practices for keeping your crypto investments safe. The combination of being offline, having robust security features, and providing backup options makes them a superior choice for anyone serious about managing their digital assets. By understanding the various complexities and taking the necessary precautions, you can significantly reduce the risks associated with cryptocurrency ownership.
