Understanding Cryptocurrency and Tokens
Cryptocurrency and tokens are related but distinct concepts in blockchain technology. While tokens represent a subset of virtual currencies, cryptocurrencies encompass a broader range of digital assets.
Core Differences Explained
| Comparison Factor | Cryptocurrency | Token |
|---|---|---|
| Definition | Digital currency operating on its own blockchain | Digital asset built on existing blockchains |
| Blockchain | Has independent blockchain (e.g., Bitcoin, Ethereum) | Runs on host blockchain (e.g., ERC-20 tokens on Ethereum) |
| Self-Sufficiency | Can operate independently | Requires host blockchain infrastructure |
| Primary Use Cases | Payments, store of value, smart contracts | Asset representation, governance, utility in dApps |
| Examples | BTC, ETH, BNB | USDT, UNI, MATIC |
Major Categories of Digital Assets
Native Cryptocurrencies (Coins)
Key Characteristics:
- Operate on proprietary blockchains
- Function as network fuel (paying transaction fees)
- Enable core blockchain operations
Notable Examples:
- BTC: The original cryptocurrency powering Bitcoin network
- ETH: Ether fuels Ethereum smart contracts
- BNB: Native currency of Binance Smart Chain
- SOL: Primary asset on Solana blockchain
Blockchain Tokens
Distinguishing Features:
- Built atop existing blockchains
- Created via smart contract standards (ERC-20, BEP-20)
- Serve specialized functions in decentralized ecosystems
Prominent Cases:
- USDT: Dollar-pegged stablecoin available on multiple chains
- UNI: Governance token for Uniswap protocol
- MATIC: Utility token for Polygon network
Practical Applications
Cryptocurrencies like BTC serve primarily as:
- Digital gold/store of value
- Peer-to-peer payment networks
- Foundation for decentralized finance
Tokens typically enable:
- Platform-specific utilities
- Governance rights in DAOs
- Specialized functions in DeFi protocols

Key Takeaways
- All tokens are cryptocurrencies, but not all cryptocurrencies are tokens
- Native coins power independent blockchains
- Tokens provide specialized functionality on host networks
- Both play crucial but distinct roles in Web3 ecosystems
Frequently Asked Questions
What's the main technical difference between coins and tokens?
Coins operate on their own blockchain while tokens are smart contracts deployed on existing blockchains. This means tokens inherit the security and functionality of their host chain.
Can a token become a coin?
Yes, through "mainnet migration" where projects launch their own blockchain. Examples include Binance Coin (BNB) which started as an ERC-20 token before Binance Chain launched.
Why are most DeFi projects built using tokens?
Tokens allow rapid deployment on established blockchains like Ethereum, providing immediate access to:
- Existing user bases
- Development tools
- Network security
- Liquidity pools
How do transaction fees differ?
Native coins pay fees in their own currency (e.g., ETH for Ethereum), while token transactions require the host chain's native coin for gas fees (e.g., ETH for ERC-20 tokens).
Which offers better investment potential?
There's no universal answer - native coins typically offer broader utility but tokens can provide targeted exposure to specific platforms or innovations. Diversification across both categories is common among crypto investors.

Are stablecoins considered tokens or coins?
Most stablecoins like USDT and USDC are tokens built on existing blockchains. However, some projects have created stablecoin-specific chains (e.g., Terra before its collapse), which would qualify as coins.
