A cryptocurrency is 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, called altcoins, 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. The most popular altcoins now (August 2016) – Ethereum, Steem, Ripple, Ethereum Classic, Litecoin, Dash, Dogecoin.

Cryptocurrencies 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.
