Coin vs Token: What Is the Difference
A coin is the native asset of its own network. A token lives on top of someone else's blockchain. The difference, and why it matters every time you make a transfer.
A coin lives on its own blockchain. A token lives on top of someone else's. Bitcoin (BTC) is a coin with its own network. USDT is a token issued on top of Ethereum, Tron, Solana, and other networks. It has no blockchain of its own.
The core difference
Coins power their own networks: paying transaction fees, participating in consensus, storing value. ETH in Ethereum, SOL in Solana, BNB in BNB Chain are each the native coin of their network. A token is created through a smart contract on an existing blockchain. Deploying a token can take minutes. Building a blockchain from scratch takes years.
Why the same asset exists on multiple networks
An issuer releases the same token on several blockchains so users can pick the network with the fees that suit them. USDT exists on Tron, Ethereum, Solana, BNB Chain, and elsewhere. One stablecoin, several different technical wrappers.
Why this matters when you exchange
When you send USDT, you must specify the network. USDT on Tron and USDT on Ethereum are different contracts. Sending on one network while expecting the recipient to receive on another means losing the funds. Always confirm the network with the person you are sending to.
The short version
Coin: its own blockchain, the foundation of its network. Token: runs on top of another blockchain. The network always matters on every transaction.
