What is Bitcoin
Bitcoin is a distributed network that maintains a ledger of balances of bitcoin-the-token. Both are referred to as "bitcoin."
The system enables payments to be sent between users without passing through a central authority, such as a bank or payment gateway. It is created and held electronically. Bitcoins aren't printed, like dollars or euros - they're produced by computers all around the world, using free software. It was the first example of what we today call cryptocurrencies, a growing asset class that shares some characteristics of traditional currencies, with verification based on cryptography.
Crypto represents the next layer of infrastructure for the internet, It will allow money to move at the speed of light around the world for free, but also offer binding, verifiable contracts, enabling anyone to do business together.
