Cryptocurrency is a type of digital currency that uses cryptography for security and anti-counterfeiting measures. Public and private keys are often used to transfer cryptocurrency between individuals. As a counter-culture movement that is often connected to cypherpunks, cryptocurrency is essentially a fiat currency. This means users must reach a consensus about cryptocurrency's value and use it as an exchange medium.
However, because it is not tied to a particular country, its value is not controlled by a central bank. With bitcoin, the leading functioning example of cryptocurrency, value is determined by market supply and demand, meaning that it behaves much like precious metals, like silver and gold. Gavin Andresen, bitcoin's technical lead, told Forbes. Because bitcoins must be cryptographically signed each time they are transferred, each bitcoin user has both public and individual private keys.
Cryptocurrency transactions are anonymous, untraceable and have created a niche for illegal transactions, like drug trafficking. Because the currency has no central repository, law enforcement and payment processors have no jurisdiction over bitcoin accounts.
For cryptocurrency supporters, this anonymity is a primary strength of this technology, despite the potential for illegal abuse, as it enables a shift in power from institutions to individuals.

That software forces the system to complete complicated calculations — imagine them digging through layers of digital rock. Bitcoin works differently from traditional currencies. Where dollars and pounds are handled by banks and financial institutions which collectively confirm when transactions occur, Bitcoin operates on the basis of a public ledger system. In order for transactions to be confirmed — to avoid the same Bitcoin from being spent twice, for example — a number of Bitcoin nodes, operated by miners around the world, need to give it their seal of approval. For that, they are rewarded the transaction fees paid by those conducting them and while there are still new Bitcoins to be made — there are currently more than In taking part in mining, miners create new Bitcoins to add to the general circulation, whilst facilitating the very transactions that make Bitcoin a functional cryptocurrency.
