Cryptocurrency Exchanges

What is cryptocurrency exchange?
Cryptocurrency exchanges are platforms that facilitate the trading of cryptocurrencies for other assets, including digital and fiat currencies. In effect, cryptocurrency exchanges act as an intermediary between a buyer and a seller and make money through commissions and transaction fees.
A crypto exchange is a platform on which you can buy and sell cryptocurrency. You can use exchanges to trade one crypto for another — converting Bitcoin to Litecoin, for example — or to buy crypto using regular currency, like the U.S. Dollar. Exchanges reflect current market prices of the cryptocurrencies they offer. You can also convert cryptocurrencies back into the U.S. Dollar or another currency on an exchange, to leave as cash within your account (if you want to trade back into crypto later) or withdraw to your regular bank account.
If you're wondering where to buy cryptocurrency, using a cryptocurrency exchange platform is likely where you'll start your investment journey. Cryptocurrency exchanges are online platforms used to buy and sell cryptocurrency. These platforms allowing users to trade cryptocurrencies using fiat money or altcoins.
Traders want to buy cryptocurrencies and trade them with each other. This is why crypto exchanges are in such a need in this industry. They allow them to buy, sell and trade their cryptocurrencies instantly, some of them serve as the fiat gateways as well, so you can even use your bank account or credit card to purchase some cryptocurrency assets.
The classic process of cryptocurrency exchanges is focused on trading similar to a stock exchange. With your fiat money or another crypto, you can exchange your assets by placing a limit order that would go to an orderbook and wait there until matched or by placing a market order that would be instantly matched with buyers and sellers requests already available in the exchange's depth of market (DOM).

Centralized vs. Decentralized Cryptocurrency Exchanges
Centralized cryptocurrency exchanges act as a third-party between a buyer and a seller. Since they are operated and controlled by a company, centralized exchanges offer more reliability. Approximately 99% of all crypto transactions go through centralized exchanges. Examples of centralized cryptocurrency exchanges include: Coinbase, GDAX, Kraken, Gemini
Decentralized cryptocurrency exchanges (DEX) allow users to execute peer-to-peer transactions without the need for a third party or an intermediary. Due to some of the issues associated with centralized exchanges, decentralized exchanges are preferred by some users.
However, decentralized exchanges do not facilitate the trading of fiat currencies for cryptocurrencies. Examples of decentralized cryptocurrency exchanges include: AirSwap, Io, Barterdex, Blocknet

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.

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 suspension.
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.

Advantages of Decentralized Cryptocurrency Exchanges

1. Mitigating hacking risk
   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 and 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. Anonymity
   Decentralized exchanges do not require customers to fill out know-your-customer (KYC) forms, offering privacy and anonymity to users.

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
   Decentralized exchanges do not allow for the trading of fiat currencies for digital ones, making 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.

How does a cryptocurrency exchange work?
With a centralized exchange, the process is basically the reverse of buying. But one advantage if you own crypto is that you probably already have everything set up.

This type of exchange is not limited to cryptocurrencies, p2p exchanges are very popular in the traditional markets as well. Its representatives are Over-the-counter desks (OTC), where you buy or sell an asset from some other individuals or companies, but confidentially. There is no order book and no direct effect on the price of the underlying asset. A typical example in the crypto sphere is the website LocalBitcoins.com, where supply meets demand in the meaning, they trade peer to peer. Mostly without a middleman, but some OTC trading desks might be used as well, where they charge fees for the mediation. OTC serves primarily for large amounts of crypto, which might have affected the price of the traded asset. Typically, it is used by large venture capital companies, hedge funds, and last but not least, for the cryptocurrency miners.

What are the benefits of using a cryptocurrency exchange?
Be careful when picking a crypto exchange. Some platforms provide wallets that do not let you transfer your coins off of the platform. This may create security risks if the exchange is hacked, or tax issues if you ever wanted to move your crypto off of the platform. You’d have to sell and rebuy your coins, which might cause you to realize some capital gains.
These platforms facilitate crypto purchases, allow you to convert cryptocurrencies back into dollars, and transfer them out of the exchange. Different exchanges come with different features, which may sway you toward choosing one exchange over another. Beyond fees, when choosing the best crypto exchange for your needs, consider things like security, trading volumes, educational resources and whether an exchange lists the cryptocurrencies you’re interested in buying.
With cryptocurrency, the transaction cost is low to nothing at all—unlike, for example, the fee for transferring money from a digital wallet to a bank account. You can make transactions at any time of the day or night, and there are no limits on purchases and withdrawals. And anyone is free to use cryptocurrency, unlike setting up a bank account, which requires documentation and other paperwork.

Others have features like crypto staking or crypto loans that allow you to earn interest on your crypto holdings. The best exchanges offer educational offerings to keep you up to date on all things crypto.
