A cryptocurrency is a digital or virtual currency designed to work as a medium of exchange
That means there’s no physical coin or bill — it’s all online. You can transfer cryptocurrency to someone online without a go-between, like a bank.
People might use cryptocurrencies for quick payments and to avoid transaction fees. Some might get cryptocurrencies as an investment, hoping the value goes up. You can buy cryptocurrency with a credit card or, in some cases, get it through a process called “mining.” Cryptocurrency mining, or cryptomining, is a process in which transactions for various forms of cryptocurrency are verified and added to the blockchain digital ledger. According to Jan Lansky,
a cryptocurrency is a system that meets six conditions:
1. The system does not require a central authority, its state is maintained through distributed consensus.
2. The system keeps an overview of cryptocurrency units and their ownership.
3. The system defines whether new cryptocurrency units can be created. If new cryptocurrency units can be created, the system defines the circumstances of their origin and how to determine the ownership of these new units.
4. Ownership of cryptocurrency units can be proved exclusively cryptographically.
5. The system allows transactions to be performed in which ownership of the cryptographic units is changed. A transaction statement can only be issued by an entity proving the current ownership of these units.
6. If two different instructions for changing the ownership of the same cryptographic units are simultaneously entered, the system performs at most one of them.
