Coin vs Token: The One Distinction That Explains Crypto
Headlines call everything a coin, but technically coins and tokens are different things. The test is a single question: does the asset have its own blockchain?
Coins: the native currency of a chain
A coin has an independent blockchain and serves as that chain's native asset for fees and rewards.
- Bitcoin (BTC) is the native currency of the Bitcoin chain.
- Ether (ETH) pays gas on the Ethereum chain.
- SOL is the native currency of Solana.
A coin's existence is tied to its chain's security and operation. As long as the chain lives, the coin exists.
Tokens: assets built on someone else's chain
A token has no chain of its own. It is issued by a smart contract on an existing blockchain.
- USDT and USDC are stablecoin tokens issued across Ethereum, Tron, and other chains.
- UNI is Uniswap's governance token on Ethereum.
- Most memecoins are tokens on Ethereum or Solana.
To transfer a token you pay fees not in the token itself but in the underlying chain's coin. Sending USDT on Ethereum requires ETH for gas. This is the single most common place newcomers get stuck.
Token standards
Tokens follow standard interfaces so wallets, exchanges, and dapps can handle them uniformly.
| Standard | Chain | Purpose |
|---|---|---|
| ERC-20 | Ethereum | Ordinary fungible tokens |
| ERC-721 | Ethereum | NFTs (non-fungible) |
| SPL | Solana | Solana-ecosystem tokens |
The same USDT exists on several chains with different address formats and fees. Choose the wrong network on a deposit or withdrawal and funds can be lost. This is why exchanges make you confirm the network twice.
Why investors should care
- The basis of value differs. A coin's demand comes from usage and security of the chain itself. A token's value depends on the issuer's business, contract design, and supply policy.
- The cost of creation differs. Launching a chain is hard; issuing a token takes minutes. This is why most scam projects are tokens.
- The checklist differs. For a token, look first at total supply, team allocation and vesting, and whether the contract is audited.
Summary
- Own chain: coin. Issued on another chain: token.
- Token transfers are paid for in the underlying chain's coin.
- Tokens are easy to issue, so always examine the issuer and the supply structure.
Get this one distinction right and wallets, fees, and listing news all become much easier to read.
