Cryptocurrency

Cryptocurrency has transformed from a niche digital experiment into a trillion-dollar global financial ecosystem. From Bitcoin’s rise in 2009 to thousands of altcoins today, crypto has disrupted traditional finance, created new forms of investment, and opened doors to decentralized applications. In 2025, understanding cryptocurrencies, their opportunities, and their risks is essential for investors, businesses, and everyday users alike.

What is Cryptocurrency?

A cryptocurrency is a digital or virtual currency secured by blockchain technology. Unlike government-issued fiat money, cryptocurrencies are decentralized, often peer-to-peer, and operate without central banks. Transactions are verified using cryptography, ensuring transparency, immutability, and security.

How Does Cryptocurrency Work?

Cryptocurrencies rely on blockchain, a distributed ledger that records transactions across multiple computers. Each transaction is stored in a block and linked to the previous block, creating a secure chain. Miners or validators confirm these transactions through consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS).

Popular Cryptocurrencies in 2025

• Bitcoin (BTC) – The first and largest cryptocurrency by market capitalization.
• Ethereum (ETH) – Known for its smart contracts and decentralized applications (dApps).
• Stablecoins (USDT, USDC) – Pegged to fiat currencies for reduced volatility.
• Altcoins – Thousands of alternatives with niche use cases like DeFi, gaming, or privacy.
