What Are Cryptocurrencies?
Cryptocurrencies belong to the high-risk asset class, involving significant investment risks including potential loss of capital. The information provided here is for educational purposes only and does not constitute financial advice. Always conduct your own research before investing.
When people mention cryptocurrencies, Bitcoin (BTC) often comes to mind first. While Bitcoin pioneered the space, it's just one part of a vast ecosystem that now includes thousands of alternatives like Litecoin (LTC) and Ethereum (ETH). These digital assets are increasingly recognized as payment methods and beyond, but understanding their fundamentals, risks, and security measures is crucial for potential investors.

- 2013: Ethereum was conceptualized by Vitalik Buterin, introducing smart contract functionality.
- 2022: Ethereum completed "The Merge," transitioning from Proof-of-Work (PoW) to Proof-of-Stake (PoS), reducing energy consumption by 99.9%.
Market Evolution
- 2010: BTC price rose from $0.003 to $0.09
- 2011: First mini bull cycle (peaked at $32)
- 2017: Historic bull run (reached $20,000)

How Cryptocurrencies Work
Cryptocurrencies are decentralized digital currencies using cryptography for security. Unlike traditional fiat currencies:
- No central authority controls issuance
- Transactions are peer-to-peer
- All transactions are recorded on public ledgers (blockchains)
Blockchains consist of sequentially linked "blocks" containing transaction details (timestamp, value, unique ID). Once added, blocks become immutable public records.
