In the world of blockchain and cryptocurrency, you’ll often hear the terms "coin" and "token" used—sometimes interchangeably. But these two concepts are fundamentally different. For example, is Bitcoin a coin or a token? What about Ethereum? This article will clarify the distinctions and help you understand the unique roles each plays.
Understanding Basic Terminology
What Is a Coin?
A coin—often referred to as a cryptocurrency—is a digital currency created using cryptographic techniques. It operates on its own native blockchain and functions primarily as a medium of exchange, store of value, or unit of account. Bitcoin is the most well-known example.
Key attributes of a coin include:
- Being built on an independent blockchain
- Serving as digital money
- Being mineable, transferable, and receivable
Coins are generally used for payments, value storage, and financial transactions—much like traditional money.
What Is a Token?
A token is a digital asset built on top of an existing blockchain. Tokens represent assets or utilities and are often issued through smart contracts. They can serve various functions within a specific project or ecosystem.
Common characteristics of tokens:
- They operate on an existing blockchain (e.g., Ethereum, Binance Smart Chain)
- They can represent assets, voting rights, or access to services
- They are often created using standardized templates like ERC-20
Tokens aren’t native to the blockchain they run on—they rely on the underlying network’s security and functionality.
Key Differences Between Coins and Tokens
Although both are forms of digital assets, coins and tokens differ in several important ways:
| Feature | Coin | Token |
|---|---|---|
| Blockchain | Has its own blockchain | Built on an existing blockchain |
| Function | Currency, store of value | Utility, asset representation |
| Creation | Requires building a blockchain | Often created via smart contract |
| Examples | Bitcoin (BTC), Ethereum (ETH) | Chainlink (LINK), Uniswap (UNI) |
How Tokens and Coins Work Together
It’s common for people to confuse these terms because all coins and tokens fall under the broad category of "cryptocurrencies." However, not all cryptocurrencies function as actual currencies.
For instance, while Bitcoin acts as digital cash, many other so-called "coins" do not serve as a widely accepted medium of exchange. Similarly, tokens often have specialized uses within decentralized applications (dApps) or platforms.
You can use coins to purchase tokens, but the reverse isn’t always true. Tokens are generally tied to a specific platform or use case.

Frequently Asked Questions
Can a token become a coin?
Yes. Some projects initially launch tokens on an established blockchain and later migrate to their own mainnet, at which point the token may become a native coin. This process is often referred to as a "swap" or "mainnet migration."
Is Ethereum a coin or a token?
Ethereum (ETH) is the native cryptocurrency of the Ethereum blockchain, which makes it a coin. However, many tokens are built on the Ethereum network using its smart contract functionality.
Why are tokens easier to create than coins?
Creating a token doesn’t require building a new blockchain from scratch. Developers can use existing platforms like Ethereum, which provide token standards (e.g., ERC-20) that simplify the process.
What are some common types of tokens?
- Utility tokens: Provide access to a product or service
- Security tokens: Represent ownership or equity in an asset
- Governance tokens: Allow holders to vote on project decisions
Can tokens be used as money?
While some tokens are designed as payment methods within their ecosystems, they are not generally accepted as universal currency like Bitcoin or Ethereum.
How do I store coins and tokens?
Both can be stored in cryptocurrency wallets. Coins require a wallet compatible with their native blockchain, while tokens must be stored in a wallet that supports the smart contract platform they’re built on.
Conclusion
Understanding the difference between coins and tokens is essential for anyone interested in cryptocurrency. Coins function as digital money on their own blockchains, while tokens represent assets or utilities on existing networks. Though the terms are often used interchangeably, they refer to distinct concepts with different purposes, technical structures, and use cases.
Whether you’re investing, developing, or simply learning, recognizing these differences will help you navigate the crypto landscape with greater confidence.
