Understanding the world of cryptocurrency starts with mastering its language. As the digital asset space evolves, so does the terminology—especially when distinguishing between coins, tokens, and altcoins. While these terms are often used interchangeably, they represent fundamentally different concepts in blockchain technology. This guide breaks down each term clearly, helping you navigate the crypto landscape with confidence.
Understanding Cryptocurrency Basics
Before diving into the differences, let’s revisit what a cryptocurrency actually is.
A cryptocurrency is a form of digital or virtual currency secured using cryptography. Unlike traditional money issued by central banks, cryptocurrencies operate on decentralized networks based on blockchain technology. A blockchain is a distributed ledger that records all transactions across a peer-to-peer network, ensuring transparency, security, and immutability.
This foundational technology enables the creation of various digital assets—each serving unique purposes and built using different technical frameworks.

What Is a Coin?
A coin is a cryptocurrency that operates on its own independent blockchain. It serves as the native currency of that network and is primarily used to pay for transaction fees, reward validators (miners or stakers), and facilitate value transfer.
The most well-known example is Bitcoin (BTC), the first cryptocurrency ever created. Bitcoin runs on the Bitcoin blockchain—note the capital "B" when referring to the network, versus lowercase "b" for the coin itself.
Similarly, Ether (ETH) is the native coin of the Ethereum blockchain. While ETH is often associated with smart contracts and decentralized applications, it remains a coin because it powers its own standalone network.
Key characteristics of a coin:
- Has its own dedicated blockchain
- Used for network security and transaction validation
- Functions as digital money within its ecosystem
Coins are typically designed to be fungible, meaning each unit holds equal value and can be exchanged one-for-one—just like traditional fiat currencies.
What Is a Token?
Unlike coins, tokens do not have their own blockchain. Instead, they are built on top of existing blockchains—most commonly Ethereum—leveraging the host network’s infrastructure for transaction processing and security.
Tokens are created using standardized protocols. The most widely adopted standard is ERC-20, which defines how fungible tokens behave on Ethereum. These tokens can represent assets, access rights, or even real-world items like shares or commodities.
For example:
- Shiba Inu (SHIB) is an ERC-20 token built on Ethereum.
- Developers define token supply, distribution schedules, and utility within smart contracts before deployment.
Another major category is non-fungible tokens (NFTs), governed by standards like ERC-721. NFTs are unique digital assets—each with distinct properties—making them ideal for digital art, collectibles, gaming items, and identity verification.
Other blockchains such as Cardano, Avalanche, and Solana also support token creation through their own smart contract systems or EVM-compatible environments.
Utility Tokens
Some tokens serve specific functions within decentralized applications (dApps). These are known as utility tokens.
Imagine a gaming platform where players use a custom token to unlock levels, purchase skins, or participate in events. Though not intended for broad economic use outside the app, these tokens often gain value and are traded on exchanges.

Governance Tokens
In decentralized communities known as DAOs (Decentralized Autonomous Organizations), decision-making power is distributed among members rather than centralized leaders. Governance tokens enable this model by granting holders voting rights on proposals—such as protocol upgrades or fund allocation.
For instance, owning a governance token might allow you to vote on whether a new feature should be added to a DeFi platform. Over time, these tokens may appreciate in value based on the success and adoption of the underlying project.
What Are Altcoins?
The term altcoin is short for “alternative coin”—referring to any cryptocurrency other than Bitcoin.
When Bitcoin launched in 2009, it was the only cryptocurrency in existence. As new projects emerged with different features—like faster transactions, enhanced privacy, or smart contract capabilities—the need arose for a category to describe these alternatives.
Initially, “altcoin” meant any coin besides Bitcoin. However, due to Ethereum’s pivotal role in enabling decentralized finance (DeFi), NFTs, and dApps, many now consider Ether (ETH) to stand alongside BTC as a foundational asset.
Therefore, in modern usage—especially within investment and trading contexts—an altcoin typically refers to any cryptocurrency other than Bitcoin and Ethereum.
Examples include:
- Solana (SOL)
- Cardano (ADA)
- Polkadot (DOT)
- Chainlink (LINK)
These projects often introduce innovations in consensus mechanisms, scalability solutions, or interoperability protocols.

Frequently Asked Questions (FAQ)
Q: Can a token ever become a coin?
Yes. Some tokens start on platforms like Ethereum but later migrate to their own blockchain. For example, Binance launched BNB as an ERC-20 token before moving it to the Binance Chain. Once migrated, BNB became a native coin of its own network.
Q: Are all tokens on Ethereum called ERC-20?
No. While ERC-20 is used for fungible tokens (like SHIB or USDT), other standards exist:
- ERC-721: For non-fungible tokens (NFTs)
- ERC-1155: For semi-fungible tokens (used in gaming)
Each standard defines how tokens interact with wallets, exchanges, and smart contracts.
Q: Is Ether a coin or a token?
Ether (ETH) is a coin because it is the native currency of the Ethereum blockchain. Despite powering thousands of tokens built on its network, ETH itself operates at the base layer of the system.
Q: Do I need coins to use tokens?
Yes. To interact with tokens—such as sending them or using them in dApps—you must pay transaction fees in the host blockchain’s native coin. On Ethereum, that means paying gas fees in ETH.
Q: Are altcoins riskier than Bitcoin?
Generally speaking, yes. Bitcoin has the longest track record, largest market cap, and highest liquidity. Altcoins often carry higher volatility and speculative risk due to lower adoption or unproven technology. However, they also offer potential for high returns if successful.
Q: Can I store both coins and tokens in the same wallet?
Yes. Most modern crypto wallets (like MetaMask or Trust Wallet) support multiple assets across different blockchains. Just ensure your wallet supports both the network (e.g., Ethereum) and token standard (e.g., ERC-20).
