Cryptocurrency
A cryptocurrency is a digital-only token. It uses cryptography to regulate how the tokens are created, how they’re traded, and how secure they are. And it doesn’t use or need a central bank or government to control or manage them. Bitcoin was the first cryptocurrency, created by Satoshi Nakamoto. All cryptocurrency transactions are stored on a public, global list or ledger. That means the records are stored in different places (nodes) at once. Cryptocurrencies are exchanged electronically without one central party or middle man needed to approve the transaction.
