Wallet Basics
How Do Cryptocurrency Wallets Work?
Cryptocurrency wallets, contrary to widespread misconception, do not really hold digital assets. There is no need to use a blockchain if you have access to the necessary technologies. To put it another way, these wallets are capable of generating the information needed to transfer and receive money via the blockchain. One or more sets of public and private keys are included in this type of data.
The public and private keys are used to construct an alphanumeric identification for the wallet's address. In essence, a blockchain "address" is a precise "location" to which currencies can be transmitted. In order to receive payments, you can share your address with others but you should never reveal your private key.
Regardless of the wallet you choose, you can gain access to your digital assets using your private key. It's possible to access funds even if your computer or smartphone is compromised, as long as you have the private key (or seed phrase). It is important to note that the coins never leave the blockchain; they are only transferred from one wallet to another.
An Ethereum wallet can only receive and send Ethereum + Ethereum based tokens.

Do I Need A Crypto Wallet To Trade Crypto?
Yes, that's the simple answer. When it comes to keeping and exchanging cryptocurrency, you need a wallet address. To store your cryptocurrency, you can use the hot wallet offered by your crypto exchange, a mobile wallet you install on your phone or browser extension, or a desktop wallet. There are a variety of choices available.
Here are a few examples of the various sorts of wallets that are available:
Hot Wallet: Coinbase, Binance, KuCoin
Mobile Crypto Wallets: Trust Wallet, MetaMask
Browser Extension Crypto Wallets: MetaMask, MathWallet, Binance Chain Wallet
Desktop Crypto Wallets: Electrum, Exodus
Hot vs. Cold Wallets
Cryptocurrency wallets are classified as either "hot" or "cold" depending on their operating mode.
Any wallet that is linked to the Internet in some way is referred to as a hot wallet. Creating a Binance account and sending money to your wallet is an example of depositing into the company's hot wallet. Traders and other frequent users will appreciate how simple it is to set up these wallets and how quickly they make their money available.
As opposed to this, a cold wallet has no access to the internet. Since the keys are stored on a physical medium, they are impervious to online hacking. As such, cold wallets tend to be a much safer alternative to "keeping" your coins. Long-term investors and "HODLers" can benefit from cold storage, which is also known as cold storage.
Types Of Wallets
Software Wallets
There are numerous types of software wallets, each with its own set of features. The majority of them are linked to the Internet in some way (hot wallets). Web, desktop, and mobile wallets are a few of the more prevalent and significant varieties, and the descriptions below cover them all.
Web Wallets
You don't need to download or install anything to utilize web wallets to access blockchains. Both exchange wallets and browser-based wallet providers are included in this category. You should be able to create a new wallet and protect it with a unique password in the majority of circumstances. Some service providers, on the other hand, hold and manage your private keys. Assuming you're an unskilled user, this is a risky practice.
Desktop Wallets
A desktop wallet is a piece of software that you download and run on your own computer. In contrast to certain web-based options, desktop wallets provide you complete access to your keys and funds. "wallet.dat" will be saved locally on your computer when you create a new desktop wallet. Because it contains the private key information needed to access your cryptocurrency addresses, this file should be password-protected.
Your password will be required each time the software is launched in order to read the wallet.dat file if your desktop wallet has been encrypted. Your cash will be at risk should you lose this file or forget your password.
The importance of a backup wallet cannot be overstated.
Keep a copy of the dat file in a safe place. If you like, you can export the private key or seed phrase associated with it. In the event that your computer fails or becomes inaccessible for whatever reason, you will be able to access your funds on other devices.
In general, desktop wallets are considered more secure than web-based wallets, but it is imperative that your computer be free of viruses and spyware before you begin using a cryptocurrency wallet.
Mobile Wallets
In many ways, mobile wallets are just like their desktop equivalents, but they're optimized for use on mobile devices. QR codes may be used to transfer and receive cryptocurrency, making this a convenient option.
As a result, mobile wallets are an excellent choice for spending Bitcoin, BNB, and other cryptocurrencies in the real world on a regular basis. A well-known mobile crypto wallet is Trust Wallet.
Mobile devices, like desktops, can be infected by malicious software and spyware. This means that you should protect your mobile wallet by encrypting it and making a copy of your private keys (or seed phrase) in the event that your phone is stolen or otherwise damaged.
Hardware Wallets
A random number generator (RNG) is used to create public and private keys for hardware wallets. The device itself, which is not linked to the Internet, is then used to store the keys. Thus, hardware storage is considered one of the most secure options for cold wallets.
Despite the fact that these wallets are more secure from online attacks, they may still pose a risk if the firmware is not correctly implemented. In addition, compared to hot wallets, hardware wallets are less user-friendly and make it more difficult to get to your money.
A hardware wallet is an excellent option if you intend to keep your cryptocurrency for an extended period of time or if you have a sizable cryptocurrency portfolio. You can establish a PIN code to protect your hardware wallet as well as a recovery phrase to use if you ever misplace your wallet.
Paper Wallets
A paper wallet is a printed piece of paper containing keys and QR codes used to facilitate your cryptocurrency transactions. Because they are removed from the internet, at one point, paper wallets were considered to be more secure than other forms of cryptocurrency storage.
The Importance Of Backups
If you lose access to your bitcoin wallets, you might lose a lot of money. As a result, it's critical that you periodically create backups. Wallet.dat files and seed phrases can often be safely backed up in this manner. It is essentially the root key that generates and allows access to all the crypto wallet's private keys. Also, make a copy of your password in case you chose to encrypt it.
