What Is Cryptocurrency?
Cryptocurrency is a type of digital money.
Unlike traditional money issued by governments, cryptocurrency exists only online and operates on decentralized networks.
Think of cryptocurrency as internet-native money.
Just as email allows people to send messages directly across the world, cryptocurrency allows people to send value directly across the world.
Simple Definition
A cryptocurrency is a digital asset that uses cryptography and blockchain technology to secure transactions and record ownership.
That sounds complicated, so let’s simplify it.
Imagine you send a friend $20 using a banking app.
The bank updates its internal records to show that your balance decreased and your friend’s balance increased.
With cryptocurrency, a blockchain performs that record-keeping function instead of a bank.
No single company controls the system.
Why Was Cryptocurrency Created?
To understand cryptocurrency, it helps to understand the problem it was designed to solve.
Traditional financial systems rely on intermediaries:
- Banks
- Payment processors
- Governments
- Credit card companies
These organizations help verify and process transactions.
While they provide valuable services, they can also introduce:
- Fees
- Delays
- Restrictions
- Limited access
Cryptocurrency was created to allow people to transfer value directly without needing a trusted middleman.
The goal was to create a financial system that is:
- Open
- Global
- Accessible
- Transparent
- Resistant to censorship
What Is Bitcoin?
Bitcoin is the world’s first cryptocurrency. Readers interested in Bitcoin’s original vision can review the official Bitcoin whitepaper published by Satoshi Nakamoto.
It was introduced in 2009 by a person or group using the name Satoshi Nakamoto.
Bitcoin was created as a peer-to-peer electronic cash system.
Today, many people view Bitcoin as:
- Digital money
- Digital gold
- A store of value
- An alternative financial asset
The official Bitcoin website also provides beginner-friendly educational resources and documentation.
Why Bitcoin Matters
Bitcoin solved a major problem known as the “double-spending problem.”
Without getting overly technical, it created a way for digital money to be transferred without requiring a central authority.
This breakthrough led to the entire cryptocurrency industry.
Many newer cryptocurrencies exist today, but Bitcoin remains the largest and most recognized cryptocurrency.
What Is Blockchain?
Simply put, blockchain is the technology that powers cryptocurrency.
If you want a deeper technical explanation of blockchain technology, the educational resources from the Linux Foundation can be helpful.
Blockchain Explained Simply
Imagine a notebook shared by thousands of people.
Every time someone makes a transaction:
- The transaction is written in the notebook.
- Everyone receives a copy.
- New entries cannot easily be changed.
That shared notebook is similar to a blockchain.
A blockchain is a digital ledger that records transactions in chronological order.
Instead of being stored on one computer, copies are distributed across many computers worldwide.
How Does a Blockchain Work?
A blockchain organizes data into blocks.
Each block contains:
- Transaction information
- A timestamp
- A connection to the previous block
These blocks form a chain.
Hence the name “blockchain.”
Step-by-Step Example
Imagine Alice sends Bob 1 Bitcoin.
- Alice creates the transaction.
- The network verifies the transaction.
- The transaction enters a new block.
- The block is added to the blockchain.
- Bob receives the Bitcoin.
The transaction becomes permanently recorded.
Why Is Blockchain Considered Secure?
Several factors make blockchain technology secure.
Decentralization
Thousands of computers maintain copies of the blockchain.
There is no single point of failure.
Transparency
Transactions can be publicly verified.
Cryptography
Advanced mathematics helps secure the network.
Immutability
Once information is recorded, changing it becomes extremely difficult.
What Makes Cryptocurrency Valuable?
This is one of the most common beginner questions.
A cryptocurrency’s value comes from several factors.
Supply and Demand
If more people want an asset than are willing to sell it, the price rises.
Utility
Some cryptocurrencies provide real-world functionality.
Examples include:
- Payments
- Smart contracts
- Decentralized applications
Scarcity
Bitcoin has a maximum supply of 21 million coins.
Limited supply can increase perceived value.
Network Effects
The more people use a cryptocurrency, the more valuable the network may become.
Types of Cryptocurrencies
Not all cryptocurrencies are the same.
Understanding the major categories can make the industry easier to navigate.
Bitcoin
Bitcoin is the original cryptocurrency.
Primary use cases:
- Store of value
- Long-term investment
- Global transfers
Altcoins
An altcoin is any cryptocurrency other than Bitcoin.
The word means “alternative coin.”
Examples include:
- Ethereum
- Solana
- Cardano
- Avalanche
Altcoins often aim to improve upon or expand Bitcoin’s capabilities.
Stablecoins
Stablecoins are cryptocurrencies designed to maintain a stable value.
Many are tied to the U.S. dollar.
Examples:
- USD Coin
- Tether
A stablecoin worth $1 today is intended to remain close to $1 tomorrow.
Stablecoins are commonly used for:
- Trading
- Payments
- Moving funds between exchanges
Utility Tokens
Utility tokens provide access to specific products or services.
Examples include tokens used within blockchain ecosystems.
Governance Tokens
Governance tokens allow holders to vote on decisions affecting blockchain projects.
Think of them like voting shares in a digital community.
What Is Ethereum?
Ethereum is the second-largest cryptocurrency ecosystem after Bitcoin.
While Bitcoin primarily focuses on money and value transfer, Ethereum introduced programmable smart contracts.
Ethereum’s official website contains educational materials about smart contracts, decentralized applications, and the broader Ethereum ecosystem.
Smart Contracts Explained
A smart contract is a program stored on a blockchain that automatically executes when conditions are met.
Think of a vending machine.
You insert money.
The machine automatically delivers a product.
No employee is required.
Smart contracts work similarly.
They automate agreements without needing intermediaries.
What Are Crypto Wallets?
A crypto wallet is a tool used to store and manage cryptocurrency.
Despite the name, wallets do not actually store coins.
The blockchain stores ownership records.
Wallets store the keys that allow access to your cryptocurrency.
Think of a wallet as the key to a digital vault.
Public Keys and Private Keys
Understanding keys is extremely important.
Public Key
A public key works like an email address.
You can share it with anyone.
People use it to send cryptocurrency to you.
Private Key
A private key works like a password.
Anyone with access to your private key can access your funds.
Never share your private key.
Ever.
Types of Crypto Wallets
Hot Wallets
Hot wallets connect to the internet.
Examples:
- Mobile wallets
- Browser wallets
- Desktop wallets
Advantages:
- Convenient
- Easy to use
Disadvantages:
- More exposed to online threats
Cold Wallets
Cold wallets remain offline.
Examples:
- Hardware wallets
- Air-gapped devices
Advantages:
- Better security
- Reduced hacking risk
Disadvantages:
- Less convenient
For long-term holdings, many investors prefer cold storage.
What Are Cryptocurrency Exchanges?
A cryptocurrency exchange is a platform where users buy, sell, and trade cryptocurrencies.
Think of an exchange as a digital marketplace.
Popular examples include:
Exchanges allow users to:
- Purchase crypto
- Convert currencies
- Sell assets
- Manage portfolios
If you’ve never used an exchange before, you may want to review some educational content before opening up an account or making your first purchase. The Coinbase Learn education hub is a great place to get started.

How Cryptocurrency Transactions Work
Let’s simplify the process.
Imagine sending $50 to a friend.
With cryptocurrency:
- You enter their wallet address.
- You choose an amount.
- You sign the transaction with your private key.

Fraudsters pretend to be:
- Exchanges
- Influencers

Fake websites imitate legitimate platforms.

How to Store Crypto Safely
Security should be your top priority.
The Cybersecurity & Infrastructure Security Agency (CISA) publishes general cybersecurity best practices that are useful for protecting online accounts and digital assets.
Enable Two-Factor Authentication (2FA)
Add an extra layer of protection.
Use Strong Passwords
Avoid reused passwords.
Use a password manager if possible.
Protect Your Recovery Phrase
Your recovery phrase can restore wallet access.
Store it securely offline.
Never share it.
Beware of Links
Do not click suspicious links from:
- Emails
- Text messages
