30 Cryptocurrency Quiz Questions and Answers – OnlineExamMaker Blog (2024)

Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional fiat currencies issued by governments and central banks, cryptocurrencies operate on decentralized networks based on blockchain technology. The creation and transfer of cryptocurrencies are secured by cryptographic techniques, ensuring the integrity of transactions and the control of new coin creation.

Popular Cryptocurrencies:

1. Bitcoin (BTC): Created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto, Bitcoin is the first and most well-known cryptocurrency. It serves as a digital store of value and a medium of exchange.

2. Ethereum (ETH): Launched in 2015 by Vitalik Buterin and others, Ethereum is a decentralized platform that enables developers to build and deploy smart contracts and decentralized applications (dApps).

3. Ripple (XRP): Developed by Ripple Labs, Ripple is both a digital payment protocol and a cryptocurrency. It is designed to facilitate fast and low-cost cross-border transactions.

4. Litecoin (LTC): Created by Charlie Lee in 2011, Litecoin is often referred to as the “silver to Bitcoin’s gold.” It shares similarities with Bitcoin but offers faster transaction confirmation times.

5. Cardano (ADA), Polkadot (DOT), and Solana (SOL): These are examples of newer cryptocurrencies that have gained popularity due to their unique features and potential use cases.
