What is Cryptocurrency?
Cryptocurrency is digital money secured by cryptography. Unlike traditional currencies, it operates decentralized via blockchain technology, offering:
- Transparency: Public ledger of all transactions.
- Security: Immutable records resistant to fraud.
- Low Fees: Bypasses intermediaries like banks.

Blockchain Technology
Blockchain is a distributed ledger where transactions are recorded in "blocks" linked chronologically. Key features:
- Decentralization: No single entity controls the network.
- Consensus Mechanisms: Proof of Work (PoW) or Proof of Stake (PoS) validate transactions.
Analogy: Like a shared Google Doc where changes are visible to all and irreversible.

How Cryptocurrencies Work
- Mining: Validators solve complex math problems to add blocks (PoW).
- Staking: Holders lock coins to validate transactions (PoS).
