Popular examples of cryptocurrencies include:

Bitcoin (BTC) – The original and most valuable crypto.
Ethereum (ETH) – Powering smart contracts and decentralized apps.
Ripple (XRP), Solana (SOL), Cardano (ADA) – Offering faster and cheaper transactions.

Why Cryptocurrency Matters in 2025

Cryptocurrency isn't just for geeks or day traders anymore. In 2025, crypto is mainstream. Here's why it matters:

Decentralized Finance (DeFi) has created alternative banking systems.
Tokenization is disrupting real estate, gaming, and art markets.
Crypto loans, staking, and yield farming offer passive income.
Blockchain is enabling secure, transparent voting and supply chains.

With inflation soaring in traditional economies, crypto assets have become a hedge against fiat currency devaluation.
