What is cryptocurrency?

Cryptocurrency is a type of digital payment system that does not rely on banks to verify transactions. It is a peer-to-peer system that allows anyone, anywhere to send and receive payments. Cryptocurrency payments are not physical currencies carried and exchanged in the real world, but purely exist as digital entries in online databases that describe specific transactions.

Characteristics of cryptocurrency

  1. Decentralization: Cryptocurrency has no central issuing or regulatory authority, instead it uses a decentralized system to record transactions and issue new units.
  2. Cryptography: Cryptocurrency uses encryption to validate transactions, providing security.
  3. Digital Wallet: Cryptocurrency is stored in digital wallets.
  4. Blockchain: Cryptocurrency operates on a distributed public ledger called blockchain, which is a record of all transactions updated and held by currency holders.
