What is Cryptocurrency?

Definition: A cryptocurrency is a digital or virtual currency that uses cryptography for security. Many cryptocurrencies are decentralized and operate on technology called blockchain, which is a distributed ledger enforced by a network of computers.

Examples:

• Bitcoin (BTC)
• Ethereum (ETH)
• Ripple (XRP)

Characteristics:

• Decentralized: Not controlled by any central authority like a government or bank.
• Digital: Exists only in electronic form.
• Blockchain-based: Transactions are recorded on a blockchain, which is a chain of blocks, each containing a list of transactions.

Use Cases:

• Medium of Exchange: Used to buy goods and services.
• Store of Value: Held for its potential to increase in value.
• Investing: Cryptocurrencies can be bought and held as long-term investments, with the potential for value appreciation over time.
• Investment: Traded on cryptocurrency exchanges for potential profit.

What is a Token?

Definition: A token is a digital asset created on an existing blockchain. Unlike cryptocurrencies like Bitcoin or Ethereum, which have their own blockchains, tokens operate on top of another blockchain, most commonly Ethereum.

Types of Tokens:

• Access Services: Used within specific platforms (e.g., paying for services on a decentralized application).
• Investment: Similar to holding shares in a company.
• Governance: Voting on decisions in decentralized organizations.
• Investing: Tokens can be bought and held as long-term investments, with the potential for value appreciation over time.

What is an Exchange?

Definition: A cryptocurrency exchange is a platform that allows users to buy, sell, and trade cryptocurrencies and tokens.

Types of Exchanges:

• Centralized Exchanges (CEX): Operate like traditional stock exchanges with a central authority managing the transactions (e.g., Binance, Coinbase).
• Decentralized Exchanges (DEX): Operate without a central authority, allowing peer-to-peer trading directly between users (e.g., Uniswap, SushiSwap).

Examples:

• Binance: A popular centralized exchange offering a wide range of cryptocurrencies.
• Coinbase: A user-friendly centralized exchange for buying and selling cryptocurrencies.
• Uniswap: A decentralized exchange operating on the Ethereum blockchain.

Use Cases:

• Trading: Buying and selling cryptocurrencies and tokens for profit.
• Investing: Purchasing cryptocurrencies to hold and potentially gain value.
