Token vs Coin: What is the Difference?

In casual conversation, "coin" and "token" are used interchangeably. In crypto, they refer to technically different things — and the difference affects how you evaluate an asset.

A coin is the native currency of its own blockchain. Bitcoin (BTC) runs on the Bitcoin network. Ether (ETH) runs on Ethereum. SOL runs on Solana. These coins pay for transaction fees (gas), reward validators or miners, and serve as the base unit of account on their respective chains. They're baked into the protocol itself.

A token is created on top of an existing blockchain using a smart contract standard. UNI, LINK, AAVE, SHIB — all are ERC-20 tokens deployed on Ethereum. They don't have their own blockchain. They ride on Ethereum's infrastructure, using ETH to pay for the gas needed to transfer them. Over 500,000 ERC-20 tokens have been deployed on Ethereum alone.

The analogy that holds up: a coin is like a country's official currency, issued by the nation itself. A token is like a casino chip or a gift card — created by a specific entity and accepted within a specific context, but relying on the underlying economy (the blockchain) for settlement.

The coin vs. token distinction affects three things that matter for trading.

Gas dependencies. To move any ERC-20 token, you need ETH in your wallet to pay gas. If you hold $10,000 in USDC but zero ETH, you can't transfer it. This catches people off guard — especially when gas prices spike during volatile markets, exactly when you need to move funds urgently. On Solana, you need SOL. On BNB Chain, you need BNB. Always keep enough of the native coin to cover gas.

Network effects. A coin's value is directly tied to its blockchain's usage. More dApps on Ethereum → more gas demand → more ETH burned → potentially higher ETH price. A token's value depends on its specific protocol's success — UNI is valuable because Uniswap generates fee revenue, not because Ethereum's gas demand is high.

Migration risk. Tokens can be redeployed on other chains. USDC exists on Ethereum, Solana, Arbitrum, and a dozen other networks. If activity migrates from Ethereum to Solana, USDC works fine on both — but ETH loses gas revenue. Coins are chain-locked; tokens are chain-fluid.

GaiaEx lists both coins (BTC, ETH, SOL) and tokens (UNI, LINK, AAVE, etc.) across spot and perpetual markets. From a trading perspective, the mechanics are identical — place orders, manage positions, take profit or cut losses. The coin/token distinction matters most for deposits and withdrawals: when moving assets to or from your GaiaEx wallet, make sure you're using the correct network and have enough native coin for gas. Sending an ERC-20 token on Ethereum when gas is $50 per transaction is a different experience than sending the same token on Arbitrum for $0.10.
