Unlike traditional currencies issued by governments, cryptocurrencies operate on decentralized networks based on blockchain technology. This means that they are not controlled by any central authority, making them immune to government interference or manipulation.How Does Cryptocurrency Work?
Cryptocurrency transactions are verified through blockchain technology, which is a distributed ledger that records all transactions across multiple computers. These transactions are grouped into blocks and then linked together to form a chain. Blockchain ensures transparency, security, and immutability of the transaction records.The Most Popular Cryptocurrencies

- Ripple (XRP): Known for its focus on facilitating cross-border payments and working with financial institutions.
- Litecoin (LTC): Often referred to as the silver to Bitcoin's gold, Litecoin is designed for faster transactions.
- Cardano (ADA): A blockchain platform that focuses on security, scalability, and sustainability through a scientific approach.
