Cryptocurrency is a digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (fiat money), cryptocurrencies are decentralized and often operate on blockchain networks. blockchain is considered highly secure. Each block is cryptographically linked to the previous one, and consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS) prevent fraudulent changes. However, vulnerabilities can still exist at the application level, especially in smart contracts, so ongoing audits and testing are essential.
