What is an Exchange?
A Crypto exchange is a marketplace where cryptocurrencies are traded for other Cryptocurrencies and also for traditional Fiat currencies. The core function of an exchange is to ensure fair and orderly trading and the efficient dissemination of price information for any Cryptocurrency trading on that exchange. Exchanges give Cryptocurrency projects, a platform from which to sell Cryptocurrencies to the investing public.
Types of Crypto Exchanges?
There are four different types of crypto exchanges:
Centralized exchanges (CEX)
Decentralized exchanges (DEX)
Swap exchanges
What is a centralized exchange?
A centralized exchange operates similar to the banks, transactions are controlled by the owners of the exchanges. Users of Centralized exchanges do not have control of their private keys.
As Andreas Antonopoulos said: “your keys, your Bitcoin. Not your keys, not your Bitcoin.
What is a decentralized exchange?
A decentralized exchange (DEX) is a peer-to-peer service which allows users to transact directly with other parties, without the supervision & involvement of a central authority.
One of the key aspects of DEX´s it´s censorship resistance As any application built on a decentralized blockchain it can't be shut down unless the entire chain gets shut down, this is important as many countries have banned or heavily restricted cryptocurrency use.
Also Dex´s can facilitate faster and cheaper transactions as code does all the validations there´s no middleman taking a cut.
it's not an easy undertaking to decentralize every aspect of an exchange marketplace and while some have nailed down the basic functionalities of swapping coins with other users the more advanced functionalities are by and large not present someone used two robust and complex centralized stock trading platforms would be woefully disappointed moving to a decentralized cryptocurrency exchange so in that aspect Dex is still have some catching up to do with centralized exchanges that can generally provide more robust features and a better user experience Dex's are no doubt an important part of the future of cryptocurrency
What is a Swap exchange?
Swap exchanges are exchanges which have simplified the process of trading, where you simply send them a specific currency and then they will swap it and take a small fee and then send you the new cryptocurrency to whichever address you selected. This convenience comes at a cost. Traditionally these exchanges have higher fees than traditional crypto exchanges. Also some people don't like signing up on traditional crypto exchanges and going through the KYC (Know your customer) process , usually if you´re trading small amounts Swap exchanges won´t require KYC.
It’s an easy way to consolidate several tokens and or currencies into one or to take advantage of a buying opportunity quickly without having to waste time waiting for KYC verification, etc.
Do your homework before joining any Crypto Exchange
As anything in life it's important to do some work & research before joining any crypto exchange

Trading Fees If you´re a frequent trader this point takes even more relevance, Fees wildly vary between exchanges, take your time understanding the deposit & trading and withdrawal fees. You should easily find any fee-related information within the exchange website.
Deposit Methods Check beforehand what type of deposit methods are available on the exchange and its fees, ( Debit Card, Credit Card, Wire transfer, Paypal ).

Traditional wire transfer has the inconvenience of usually taking a long time for the bank to process.

Before joining, make sure no restrictions apply to the country you're currently living in , and that you have full access to all the exchange functionality.
Available Trading Pairs Always check for the available trading pairs and see if it covers what you´re looking for. Some exchanges focus on new projects that are not yet that well known, and are not easily accessible, some only trade a few pairs and only really established tokens like Bitcoin, Litecoin, Ethereum.
Liquidity is the ability of a cryptocurrency to be converted into cash or other coins without compromising cryptocurrencies' value. A high liquidity indicates a vibrant and stable market where participants can trade quickly, easily and at fair prices.
