Bitcoin is a digital currency (also called crypto-currency) that is not backed by any country’s central bank or government. Bitcoins can be traded for goods or services with vendors who accept Bitcoins as payment.
The Bitcoin network is designed to mathematically generate no more than 21 million Bitcoins and the network is set up to regulate itself to deal with inflation. Bitcoins can be spent by initiating a transfer request from a Bitcoin address in the customer’s wallet to a Bitcoin address in the vendor’s wallet. As of this writing, one Bitcoin (also called a BTC) is worth $104 — but just as with stocks, the value of Bitcoins can fluctuate quickly.
