Bitcoin was the very first decentralized digital currency. Bitcoin introduced a new technology called a blockchain, which is a database for managing transactions between individuals who know nothing about one another, without the presence of a central authority. With no more than 21 million coins ever to be produced, Bitcoin is both a new payment system and a store of value. It’s often referred to as “digital gold.”

What makes it different?
Send money to anyone, anywhere without needing a bank to confirm it. Thousands of individuals help verify these blockchain transactions — and they’re rewarded with their own bitcoin. In theory, everyone wins, except the middleman!
