Pro Tip: You can buy fractions of Bitcoin (e.g., 0.001 BTC), with the smallest unit called a satoshi (100 million satoshis = 1 BTC).
The Origins of Bitcoin
Published in 2008 by the pseudonymous Satoshi Nakamoto, Bitcoin’s whitepaper, "A Peer-to-Peer Electronic Cash System", addressed trust issues in traditional finance. Key points:
"The root problem with conventional currencies is all the trust required... central banks must be trusted not to debase currency."
The network launched in 2009, with Nakamoto disappearing in 2010. Today, Bitcoin’s code is maintained by a global developer community.
