Cryptocurrencies

Cryptocurrencies are digital or virtual currencies that use cryptography for secure transactions. They operate independently of traditional banks and are usually based on blockchain technology, which is a decentralized ledger that records all transactions.

A cryptocurrency is a digital asset that can be used as a medium of exchange, store of value, or investment. Unlike fiat money (like USD or EUR), cryptocurrencies are not issued by a central authority and rely on decentralized networks to verify and record transactions.

⭐ Key Features

1. Decentralization
   • Operates on a blockchain or distributed ledger

2. Security
   • Uses cryptographic techniques to secure transactions
   • Transactions are immutable once confirmed on the blockchain
3. Transparency & Traceability
   • Every transaction is publicly recorded on the blockchain
   • Users can verify transactions without exposing personal data
4. Digital Wallets
