How is a Cryptocurrency Exchange Different from a Cryptocurrency Wallet?

Cryptocurrency exchanges and wallets are among the most basic tools in the crypto ecosystem, their use cases differ as they address different needs. Anyone and everyone involved in the world of digital currencies must absolutely grasp these distinctions.

What is a Cryptocurrency Exchange?

A cryptocurrency exchange is a platform where users can buy, sell, and trade different cryptocurrencies. Just like a stock exchange, these exchanges are tailored for digital assets. They offer a place where normal folks can convert their fiat to crypto and back, as well as trade between cryptocurrencies.

Types of Exchanges:

Centralized Exchanges (CEXs): There are various different types but in the mainstream, CEXs (Centralized Exchanges). For example, Binance, Coinbase and Kraken. Centralized exchanges serve as intermediaries and hold users' funds while overseeing their transactions.
Decentralized Exchanges (DEXs): Platforms like Uniswap and SushiSwap allow peer-to-peer trading without an intermediary. Private keys are controlled by the user — good for security but might be more difficult for beginners to get set up.

How Exchanges Work:

Account Creation: Users register and deposit funds, either from fiat or cryptocurrency.
Trading: It accepts orders for the buying or selling of cryptocurrencies from other users. The exchange connects buyers and sellers that help to make the transaction successful.
Custody: Centralized exchanges custody takes control of users private keys and thus, funds. This is easier but less secure if the exchange gets hacked.

What is a Cryptocurrency Wallet?

A cryptocurrency wallet is a software that allows you to store, send and receive digital currencies securely. The role of wallet is the opposite to that of an Exchange as wallets are not for trading but for storing private keys securing own crypto and owned.

Types of Wallets:

Hot Wallets: These wallets are online and can be accessed through web, mobile, desktop etc. While more convenient, they are also far less secure in the face of online threats.
Cold Wallets: Hardware and paper wallets that store private keys offline for high-level security against hacking.
Custodial Wallets: A third-party account where a company holds your keys.
Non-Custodial Wallets: Private keys are held by the users (not the exchange), hence providing more security and privacy.

How Wallets Work:

Private Keys: This is a unique cryptographic code that allows the cryptocurrency to be turned over on its underlying blockchain. These keys need to be secured very carefully.
Transactions: Wallets sign transactions with the private key to establish ownership and authorize moving funds from an address.
