A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange using cryptography to secure the transactions and to control the creation of additional units of the currency.

Cryptocurrencies are a subset of alternative currencies, or specifically of digital currencies.

Bitcoin became the first decentralized cryptocurrency in 2009.

Since then, numerous cryptocurrencies have been created.

These are frequently called altcoins, as a blend of bitcoin alternative.

Bitcoin and its derivatives use decentralized control as opposed to centralized electronic money/centralized banking systems.

The decentralized control is related to the use of bitcoin's blockchain transaction database in the role of a distributed ledger.
