Cryptocurrency Exchanges and Wallets: Your Gateway to Digital Assets

In the ever-evolving world of digital finance, cryptocurrencies have become synonymous with innovation and investment opportunities. However, navigating the crypto space requires understanding two fundamental components: cryptocurrency exchanges and wallets. These tools are essential for anyone looking to invest in or use cryptocurrencies. This article will explore what they are, how they differ, and why they are crucial for your crypto journey.

Understanding Cryptocurrency Wallets and Exchanges 

What Is a Cryptocurrency Wallet ? A crypto wallet is an application that functions as a wallet for your cryptocurrency. It is called a wallet because it is used similarly to a wallet you put cash and cards in. Instead of holding these physical items, it stores the passkeys you use to sign for your cryptocurrency transactions and provides the interface that lets you access your crypto.

Modern cryptocurrency wallets make the blockchain accessible to everyone. When cryptocurrency was first introduced, sending cryptocurrency was a manual task that required entering long keys. Today, the software does most of it for you.

A cryptocurrency exchange is a platform where you can buy, sell, or trade cryptocurrencies. Exchanges can be centralized, like Coinbase or Binance, or decentralized, like Uniswap or SushiSwap. Centralized exchanges are managed by a single entity and often provide user-friendly interfaces, customer support, and a variety of services. Decentralized exchanges (DEXs), on the other hand, allow for direct peer-to-peer transactions without the need for an intermediary.

Cryptocurrency Wallet Types

There are two main types of wallets: 

Custodial and Noncustodial: Custodial wallets are hosted by a third party that stores your keys for you. This could be a company that provides enterprise-level data security systems businesses use to preserve and secure data. Some cryptocurrency exchanges offer custodial wallets for their customers. Noncustodial wallets are wallets in which you take responsibility for securing your keys. This is the type that most cryptocurrency wallets on devices are.

There are two subcategories of wallets: hot and cold. A hot wallet has a connection to the internet or to a device that has a connection, and a cold wallet has no connection. Lastly, there are three subcategories of wallets—software, hardware, and paper. Each of these types is considered either a hot or cold wallet.

So, you can have a noncustodial software hot wallet, a noncustodial hardware cold or hot wallet, or a custodial hardware cold wallet. These are the most common types, but you may also encounter other combinations.

• Software Wallets : Software wallets include applications for desktops and mobile devices. These wallets are installed on a desktop or laptop computer and can access your cryptocurrency, make transactions, display your balance, and much more. Some software wallets also include additional functionality, such as exchange integration if you’re using a wallet designed by a cryptocurrency exchange.Many mobile wallets can facilitate quick payments in physical stores through near-field communication (NFC) or by scanning a QR code. Mobile wallets tend to be compatible with iOS or Android devices. Trezor, Electrum, and Mycelium are examples of wallets that you can use. Software wallets are generally hot wallets.

• Hardware Wallets : Hardware wallets are the most popular type of wallet because you can store your private keys and remove them from your device. These devices might resemble a USB drive, and modern hardware wallets have several features. You can make a cryptocurrency transaction on your computer or device by plugging in the hardware wallet. Most of them can sign cryptocurrency transactions automatically without requiring you to enter the key, circumventing a hacker’s ability to log your keypresses or record your screen.

• Paper Wallets : Early crypto users would write or type their keys on paper, which they called paper wallets. These evolved to include the keys and QR codes so wallets on mobile devices could scan them. However, paper wallets are easily damaged or lost, so many crypto owners do not use them anymore.However, there is nothing wrong with using a paper wallet if you take measures to store it properly in a safe or deposit box and check on it once in a while to ensure it hasn’t deteriorated.

The Role of Cryptocurrency Wallets

A cryptocurrency wallet is a digital tool that allows you to store, send, and receive cryptocurrencies. Wallets can be software-based, known as ‘hot wallets,’ or hardware-based, known as ‘cold wallets.’ Hot wallets are connected to the internet and are convenient for frequent transactions, while cold wallets are offline and provide additional security for long-term storage.

Crypto Wallet Security

Wallet safety is essential, as cryptocurrencies are high-value targets for hackers. Some safeguards include encrypting the wallet with a strong password, using two-factor authentication for exchanges, and storing any large amounts you have offline.

Seed Words

Most modern wallets generate a twelve-word mnemonic seed phrase. An example phrase could be “airport bedroom impression sample reception protection road shirt…” which seems random but is created and linked to your keys by your wallet. You can use the phrase to restore the wallet if the device is lost or damaged. These words should be carefully stored in a safe place because anyone who finds them will be able to access your cryptocurrency.

What are Cryptocurrency Exchanges?

In order to start buying and selling cryptocurrencies and other digital assets, the most common way is to transact with Crypto Exchanges. Cryptocurrency exchanges are privately-owned platforms that facilitate the trading of cryptocurrencies for other crypto assets, including digital and fiat currencies and NFTs.

The most common way of transacting in cryptocurrencies and other digital assets is via a Cryptocurrency Exchange.

There are Centralized and Decentralized Cryptocurrency Exchanges, and each offers advantages and disadvantages.

Centralized Cryptocurrency Exchanges (“CEX”)

Centralized cryptocurrency exchanges act as an intermediary between a buyer and a seller and make money through commissions and transaction fees. You can imagine a CEX to be similar to a stock exchange but for digital assets.

Popular Crypto Exchanges are Binance, Coinbase Exchange, Kraken and KuCoin. Much like stock trading websites or apps, these exchanges allow cryptocurrency investors to buy and sell digital assets at the prevailing price, called spot, or to leave orders that get executed when the asset gets to the investor’s desired price target, called limit orders.

CEXs operate using an order book system, which means that buy and sell orders are listed and sorted by the intended buy or sell price. The matching engine of the exchange then matches buyers and sellers based on the best executable price given the desired lot size. Hence, a digital asset’s price will depend on the supply and demand of that asset versus another, whether it be fiat currency or cryptocurrency.

CEXs decide which digital asset it will allow trading in, which provides a small measure of comfort that unscrupulous digital assets may be excluded from the CEX.

Decentralized Cryptocurrency Exchanges (“DEX”)

A decentralized exchange is another type of exchange that allows peer-to-peer transactions directly from your digital wallet without going through an intermediary. Examples of DEXs include Uniswap, PancakeSwap, dYdX, and Kyber.

These decentralized exchanges rely on smart contracts, self-executing pieces of code on a blockchain. These smart contracts allow for more privacy and less slippage (another term for transaction costs) than a centralized cryptocurrency exchange.

On the other hand, even though smart contracts are rules-based, the lack of an intermediary third party means that the user is left to their own, so DEXs are meant for sophisticated investors.

Advantages of Centralized Cryptocurrency Exchanges

1. User-friendly

Centralized exchanges offer beginner investors a familiar, friendly way of trading and investing in cryptocurrencies. As opposed to using crypto wallets and peer-to-peer transactions, which can be complex, users of centralized exchanges can log into their accounts, view their account balances, and make transactions through applications and websites.

2. Reliable

Centralized exchanges offer an extra layer of security and reliability when it comes to transactions and trading. By facilitating the transaction through a developed, centralized platform, centralized exchanges offer higher levels of comfort.

3. Leverage

One of the other benefits of certain CEXs is the option to leverage your investments using borrowed money from the exchange, called margin trading. It allows investors to reap higher returns, but losses can also be amplified.

Disadvantages of Centralized Cryptocurrency Exchanges

1. Hacking risk

Centralized exchanges are operated by companies that are responsible for the holdings of their customers. Large exchanges usually hold billions of dollars worth of bitcoin, making them a target for hackers and theft.

An example of such an incident is Mt.Gox, which was once the world’s largest cryptocurrency exchange company before it reported the theft of 850,000 bitcoins, leading to its collapse.

2. Transaction fees

Unlike peer-to-peer transactions, centralized exchanges often charge high transaction fees for their services and convenience, which can be especially high when trading in large amounts.

3. Custody of digital assets and risk of fraud

Lastly and most importantly, most CEXs will hold your digital asset as a custodian in their own digital wallet rather than allow you to store your private keys on your own digital wallet. While more convenient when you want to trade, there are drawbacks, namely the risk of the centralized cryptocurrency exchange failing and fraud.

Recent examples include the failure of the 50 USD billion algorithmic stablecoin TerraUSD and sister token Luna, the bankruptcies of hedge fund Three Arrows Capital, lender Celsius Network, broker Voyager Digital and the sudden collapse of FTX and Alameda Research.

Advantages of Decentralized Cryptocurrency Exchanges

1. Custody

Users of decentralized exchanges do not need to transfer their assets to a third party. Therefore, there is no risk of a company or organization being hacked, and users are assured of greater safety from hacking, failure, fraud, or theft.

2. Preventing market manipulation

Due to their nature of allowing for the peer-to-peer exchange of cryptocurrencies, decentralized exchanges prevent market manipulation, protecting users from fake trading and wash trading.

3. Less censorship

Decentralized exchanges do not require customers to fill out know-your-customer (KYC) forms, offering privacy and anonymity to users. Since DEXs don’t exercise censorship, more cryptocurrencies and digital assets are available than through a CEX. As a matter of fact, many Altcoins are only available on DEXs.

Disadvantages of Decentralized Cryptocurrency Exchanges

1. Complexity

Users of decentralized exchanges must remember the keys and passwords to their crypto wallets, or their assets are lost forever and cannot be recovered. They require the user to learn and get familiar with the platform and the process, unlike centralized exchanges, which offer a more convenient and user-friendly process.

2. Lack of fiat payments

DEXs are best for investors looking to switch from one digital asset to another and not well suited for someone looking to buy or sell digital assets with fiat currency, called on and off-ramping. It makes them less convenient for users that do not already hold cryptocurrencies.

3. Liquidity struggles

Some 99% of crypto transactions are facilitated by centralized exchanges, which suggests that they are accountable for the majority of the trading volume. Due to the lack of volume, decentralized exchanges often lack liquidity, and it can be difficult to find buyers and sellers when trading volumes are low.
