"A cryptocurrency is a digital asset that individuals exchange to purchase goods and services. Unlike normal currencies typically managed by a central authority within a sovereign state, cryptocurrencies are decentralized. Individual nodes along a blockchain manage cryptocurrencies, thereby providing transparency and the security of the currency. This prevents the value of the currency from being manipulated by a single authority. Cryptocurrencies are exchanged directly between two parties using public and private keys, usually with little or no processing fees."
