So what exactly is Bitcoin? Bitcoin is a digital currency and digital payment system that allows people to send and receive Bitcoins â or digital tokens â to anyone, anywhere in the world. It runs on a decentralized network of computers in which all transactions are recorded, verified and updated by technology known as blockchain, which is akin to an online public ledger.
The definition of bitcoin is a publicly-owned, digital form of currency that uses cryptography (information security algorithms) to securely send and receive payments. An example of bitcoin is the digital money that can be allocated using a cell phone to donate to an Internet site such as Wikileaks.
