How Crypto Exchanges Work?

How Crypto Exchanges Work?

Cryptocurrency exchanges typically work in the following way:

1. Create an Account

The first step is to create an account with a cryptocurrency exchange. This usually involves providing some personal information, such as your name, email address, and phone number.

  • Exchanges require this info to verify your identity and ensure compliance with Know Your Customer (KYC) regulations.
  • Strong password protocols and two-factor authentication (2FA) provide account security.

2. Deposit Funds

Once you have created an account, you need to deposit funds into it. You can do this by transferring fiat currency (such as USD or EUR) from your bank account or by sending cryptocurrencies from another wallet.

  • Fiat deposits allow you to directly buy crypto with funds from your bank.
  • With crypto deposits, you can trade between cryptocurrencies without converting to fiat.
  • Minimum and maximum deposit limits may apply depending on verification level.

3. Place a Buy or Sell Order

Once you have deposited funds, you can place a buy or sell order for the cryptocurrency you want to trade. You can specify the price you are willing to pay or sell the cryptocurrency at, or you can use a market order to buy or sell the cryptocurrency at the current market price.

  • Market orders fill at current prices immediately, while limit orders set a price and may not fill right away.
  • Exchanges match orders from their books and execute trades.
  • Advanced orders like stop losses let you plan exits based on price.

4. Execute the Trade

Once you have placed an order, the exchange will match your order with another user’s order and execute the trade. The cryptocurrency you bought or sold will then be deposited into your account.

  • Settlement times vary by exchange but are often fast, especially with crypto-to-crypto trades.
  • You can track order status on the exchanges order pages and transaction history.
  • Trades incur fees, such as trading commissions and network costs for withdrawals.

How Does A Cryptocurrency Exchange Function?

Cryptocurrency exchanges function in a variety of ways, but there are some common features that most exchanges share.

Matching Engines and Order Books

One common feature is that exchanges typically use a matching engine to match buyers and sellers. This engine takes into account the price and quantity of orders that have been placed and matches them up in a way that is fair and efficient.

  • The engine matches orders from the exchange’s order book, which lists open buy and sell orders.
  • Orders execute based on price-time priority, with the best price filled first.
  • Matching engines use algorithms to fill orders in a fast, liquid market.

Trading Fees

Another common feature is that exchanges typically charge fees for their services. These fees may vary depending on the exchange and the type of trade being executed.

  • Common fee types include maker/taker fees, deposit/withdrawal fees, and account fees.
  • Fees are usually a percentage of the total transaction amount.
  • Higher-volume traders may get discounts on trading fees.

Security Features

Finally, most exchanges offer a variety of security features to protect their users’ assets. These features may include two-factor authentication, cold storage, and insurance.

  • 2FA requires an extra login step using your phone or other device.
  • Cold storage keeps crypto funds offline in secure wallets.
  • Insurance compensates users in case of loss of funds due to exchange hacks or failure.

Why Should Someone Consider Using a Cryptocurrency Exchange?

There are a number of reasons why someone might consider using a cryptocurrency exchange:

Convenient Trading

One reason is that cryptocurrency exchanges offer a convenient way to buy, sell, and trade cryptocurrencies. Exchanges typically have a wide selection of cryptocurrencies available to trade, and they offer a variety of trading tools and features.

  • Easy account creation and verification gets you trading quickly.
  • Intuitive order forms and detailed charts allow efficient trades.
  • Apps offer trading on the go from your smartphone or tablet.

Secure Storage

Another reason is that cryptocurrency exchanges can provide a safe and secure way to store cryptocurrencies. Many exchanges offer cold storage for their users’ assets, and they have a variety of security features in place to protect their users from fraud and theft.

  • Offline cold wallets provide better protection than hot online wallets.
  • Multi-signature and 2FA authentication adds layers of account security.
  • Insurance covers losses from exchange hacks, theft or failure.

Learning and Investing

Finally, cryptocurrency exchanges can be a good way to learn about and invest in cryptocurrencies. Many exchanges offer educational resources and tools to help users learn more about cryptocurrencies and how to trade them.

  • Articles, videos, and guides teach crypto basics and advanced trading strategies.
  • Some exchanges have simulated trading platforms to practice on.
  • You can build a diversified crypto portfolio by buying into different assets.

How to Start a Cryptocurrency Exchange

Starting a cryptocurrency exchange is a complex and challenging task. There are a number of things that you need to do to get started, including:

Obtain Licenses and Permits

Cryptocurrency exchanges are regulated in many jurisdictions, so you need to obtain the necessary licenses and permits before you can start operating an exchange.

  • Money transmitter licenses are required at state, federal, and international levels.
  • Regulations deal with KYC rules, consumer protection, and anti-money laundering.
  • Consult lawyers to ensure compliance with all applicable regulations.

Develop a Trading Platform

You need to develop a trading platform that is secure and easy to use. This platform should allow users to buy, sell, and trade cryptocurrencies.

  • Work with developers to code exchange software and infrastructure.
  • Ensure platform is fast, reliable, and equipped to handle heavy traffic.
  • Mobile apps make trading convenient on smartphones and tablets.

Implement Security Protocols

Security is critical – implement robust protocols to protect user assets and data. Measures should include:

  • Cold wallet storage for crypto funds.
  • Multi-factor authentication for account access.
  • Data encryption and cybersecurity monitoring.
  • Insurance coverage for deposits.

Offer Customer Support

Provide customer service channels like email, phone, and ticketing to address user issues promptly. Customers will need help with:

  • Account setup and funding questions.
  • Fixing problems with trades or withdrawals.
  • Understanding fees and how the exchange works.

Market and Promote

Getting the word out about your exchange will be key. Some promotional tactics include:

  • Paid ads on search engines, social media, and crypto websites.
  • Affiliate and referral programs to incentivize sign-ups.
  • Promotional offers like fee discounts to attract traders.

How is a Cryptocurrency Exchange Different From a Cryptocurrency Wallet?

While they both deal with cryptocurrencies, exchanges and wallets serve different primary functions:


  • Exchanges facilitate trading cryptocurrencies, converting to fiat, and token investing
  • You don’t have direct control of crypto stored on an exchange
  • Trades occur directly through the exchange’s books and wallets


  • Wallets securely store crypto assets and enable transactions
  • You fully control private keys for crypto held in a wallet
  • Self-hosted wallets remove reliance on a third party like an exchange

Some key differences:

  • Exchanges act as custodians and hold crypto on users’ behalf, while wallets give the user direct control.
  • Wallets emphasize security through private keys and control of assets. Exchanges optimize for convenient trading and transactions.
  • While exchanges allow trading between currencies, wallets only facilitate transactions in a currency they support.
  • Wallets are suited for passive holding, while active trading requires an exchange account.

So in summary – exchanges facilitate trading and conversion between currencies, while wallets provide secure storage and direct control. Many crypto holders use both.

How to Select the Proper Exchange for Your Investing Needs?

Choosing a suitable cryptocurrency exchange for your needs requires research and due diligence. Here are some key factors to consider:

Location and Legality

  • Make sure the exchange serves your country or state and complies with regulations.


  • Compare trading fees between exchanges – they can really add up with active trading.


  • Review how the exchange stores crypto funds and protects accounts from unauthorized access.

Supported Coins

  • Exchanges offer different coin listings – be sure they support what you want to trade.


  • Look for exchanges with higher trading volume and tighter spreads for the pairs you’ll trade.

User Experience

  • Test the exchange’s platform, apps, and tools to ensure an intuitive experience.

Be Cautious of New or Unregulated Exchange

While the above factors help select a quality exchange, it’s also important to be cautious and avoid exchanges with red flags, such as:

  • Unregistered exchanges that don’t comply with regulations. This increases risks.
  • New exchanges that are unproven and may not have robust infrastructure.
  • Exchanges located in countries with poor regulatory oversight. They may take more risks with user funds.
  • Anonymous teams that lack transparency and accountability. Make sure the exchange founders and leadership are public.
  • Exchanges with a history of significant outages, hacks or losing user funds point to poor management.

Do Your Research on Exchange Reputation and Reviews

Before selecting an exchange, be sure to:

  • Research online for user reviews – look for common complaints or praises.
  • Check forums and sites like Reddit for community feedback and experiences.
  • Search if the exchange has had issues like hacks, outages, or regulatory problems.
  • Look for professional exchange reviews that objectively assess pros and cons.
  • See how responsive the exchange’s customer support is by contacting them before signing up.

Taking the time to research thoroughly will help avoid exchanges with bad practices or mismanagement.

Go With Exchanges that Offer Higher Security

Since you are entrusting exchanges with your funds, it makes sense to use ones that prioritize security features such as:

  • Cold storage wallets that keep most crypto offline unavailable to hackers.
  • Multi-factor authentication requiring an extra step like an OTP code to login.
  • Address whitelisting so withdrawals only go to approved addresses.
  • Transaction monitoring that detects suspicious trading activity indicative of fraud.
  • Email and SMS notifications alerting on withdrawals and other account changes.
  • Insurance coverage that reimburses users in case funds are lost or stolen.

Beware of Exchanges With Higher Fees or Limited Coins

Two red flags to watch out for when choosing an exchange are:

High Fees

Excessive trading, deposit, or withdrawal fees can cut into your profits. Watch out for:

  • Trading fees over 0.5% for takers and 0.2% for makers.
  • Withdrawal fees higher than the typical network transaction fee.
  • High deposit fees on fiat transfers or wire purchases.
  • Account fees just for signing up or having an account.

Limited Coin Support

Having a wide range of cryptocurrencies to choose from is useful. Be cautious if an exchange only offers:

  • One or two major coins like BTC and ETH but few altcoins.
  • Many obscure coins but excludes top 10 or 20 currencies.
  • Few trading pairs, reducing liquidity for trades.
  • Few fiat currency gateways to convert between crypto and cash.
