Cryptocurrency Key Terms FAQ

What’s the difference between a coin and a token?

Coins (like Bitcoin) operate on their own blockchain, while tokens (like UNI or USDC) are built on existing blockchains and represent assets or utilities.

Why are private keys so important?

Private keys are cryptographic proof of ownership. Lose them, and you permanently lose access to your crypto assets. Never share them!

How does staking differ from mining?

Mining uses computational power to validate transactions (Proof-of-Work), while staking involves locking crypto holdings to support network operations (Proof-of-Stake), typically with lower energy consumption.

Are all cryptocurrencies decentralized?

Not necessarily. While Bitcoin and Ethereum are decentralized, some projects (like Ripple’s XRP) have significant centralized control. Always check a project’s governance model.

What does “Web3” mean in crypto context?

Web3 refers to the next internet evolution featuring decentralized protocols, blockchain integration, token-based economics, and user-controlled data.
