What is Bitcoin?
Bitcoin is an entirely digital, global currency launched in 2009: it is a fully decentralized monetary system with no central authority that regulates the monetary base.
What does this mean? Well, it is money, currency, that can be sent over the internet to transfer money or to make payments to anyone. However, it is not physical money.
Think of how email allows us to send a digital message to anyone in the world, for free. Bitcoin is very much the same concept, but for money:
- Email is a digital version of paper mail.
- Bitcoin is a digital version of paper cash.
You can store digital cash in your wallet or send a payments instantly to anyone, without having to register or sign up. You just send your bitcoins to the right address.
Key properties of Bitcoin:

The currency and its transactions are encrypted with the the toughest cryptographic hash functions available and virtually impossible to compromise or counterfeit.

All transactions are transparent and public. However, while every transaction is viewable by anyone, the parties or individual attached to the transactions remain anonymous.

Worldwide
Any transfers can occur from anywhere connected to the internet, and are not constrained by geographic, political boundaries nor imposed any transfer or conversion rates.

Most Bitcoin transactions can be done for no fees, or for just a few optional cents regardless of transaction size. Compare that to wire transfers or credit card transactions.
