Cryptocurrencies serve diverse functions across finance, technology, and entertainment. This guide explores key distinctions between digital assets, their use cases, and emerging trends in blockchain innovation.
Coins vs. Tokens: Fundamental Differences
Coins (Native Blockchain Assets)
- Operate on independent blockchains (e.g., Bitcoin, Ethereum)
Function as:
- Stores of value (BTC)
- Network fuel for smart contracts (ETH)
- Transaction fees paid in native coins (BTC for Bitcoin network, ETH for Ethereum gas)
Tokens (Built on Existing Blockchains)
- Represent assets/utilities within ecosystems
Examples:
- Axie Infinity (SLP): Play-to-earn gaming currency
- Uniswap (UNI): Decentralized exchange governance token
- Basic Attention Token (BAT): Brave browser rewards system
