Coin

Most popular terms Beginner

A coin in cryptocurrency is a digital asset that operates on its own blockchain. It is the native currency of that network, used to pay for transactions, secure the blockchain, and incentivize participants. Coins often act as a medium of exchange, store of value, and unit of account within their ecosystem.

What Is a Coin?

A coin is a type of cryptocurrency that runs on its own blockchain. Unlike tokens, which are built on top of existing blockchains, coins are native assets to the networks they power.

Coins have several key functions:

  • Payments and transfers: used to send value directly between users without intermediaries.
  • Transaction fees: required to process and confirm transactions on the blockchain.
  • Security and incentives: given as rewards to miners or validators who keep the network safe.
  • Economic backbone: measure value within the blockchain and often influence the network’s economy.

Examples include:

  • Bitcoin (BTC): the first cryptocurrency, designed as digital money and store of value.
  • Ethereum (ETH): powers smart contracts and decentralized applications.
  • BNB: used for transaction fees, governance, and ecosystem utilities on the BNB Chain.

Unlike tokens, which rely on another blockchain to exist, coins are self-sustaining assets tied directly to the health, usage, and growth of their blockchain.

The Role of Coins in Crypto

Coins are essential to blockchain ecosystems. They act as:

  • Mediums of exchange for transferring value peer-to-peer
  • Incentives for miners or validators who secure the network
  • Units of account for measuring value within the ecosystem
  • Stores of value, with some coins (like Bitcoin) seen as digital gold

Coins can also play a governance role, enabling holders to vote on network upgrades and policies.

Coins vs. Tokens

Coins and tokens are both types of cryptocurrencies, but they serve different purposes and are created in different ways.

Coins

  • Run on their own blockchain (e.g., Bitcoin on the Bitcoin blockchain, Ether on Ethereum).
  • Used mainly for payments, transaction fees, and securing the network.
  • Often designed to act as money, store value, or provide rewards to network validators.
  • Can be mined or staked depending on the blockchain’s consensus mechanism.

Tokens

  • Built on existing blockchains using smart contracts (e.g., USDT or SHIB on Ethereum).
  • Used for a wide range of purposes, such as stablecoins, governance, gaming, or representing assets.
  • Do not usually secure the blockchain itself but rely on the underlying network for security.
  • Easier to create compared to launching an entirely new coin with its own blockchain.

FAQ

Is Bitcoin a coin or a token?

Bitcoin is a coin, not a token. Coins like BTC operate on their own native blockchain, while tokens are built on top of another blockchain (e.g., ERC-20 tokens on Ethereum). Since Bitcoin has its own independent network, it’s classified as a coin.

What is the difference between a coin and a token?

A coin is a cryptocurrency that runs on its own blockchain (e.g., Bitcoin, Ethereum). A token is a digital asset built on an existing blockchain, relying on its infrastructure for transactions and security (e.g., USDT on Ethereum). In short: coins are native to blockchains, tokens are created on top of them.

Can new coins be created?

Yes. Developers can launch new blockchains and issue native coins, but creating and maintaining a blockchain requires significant resources.

Which are the most popular crypto coins?

Bitcoin (BTC), Ethereum (ETH), and BNB are among the most widely used and traded coins in the crypto market.
