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.
Bitcoin is the most well known, highly valued, and actively traded cryptocurrency in active existence today; and as of this writing there are more than 15 million bitcoins in circulation. The USD value of a bitcoin (BTC) is currently about $695 , which gives a market capitalization of about $11 billion.
