Plain-language guides to what Bitcoin is, who created it and how it grew from a 2008 whitepaper into a global network, before you spend a dollar on it.
Bitcoin basics are the core ideas you need before anything else: what Bitcoin is, how it differs from ordinary money, who created it and why. This section covers those foundations for anyone searching for what Bitcoin is, who started it or who owns it. The place to begin is What Is Bitcoin?, a plain-English introduction to the network, the coin and the main risks.
The second guide, The History of Bitcoin, follows the story from the whitepaper of 31 October 2008 and the first block on 3 January 2009 through halvings, exchange failures and the arrival of US spot Bitcoin ETFs in January 2024. Its creator, Satoshi Nakamoto, used a pseudonym, and nobody has proven who that person or group was. If you wonder who owns Bitcoin, the short answer is nobody owns the network, and the history shows why.
If you want a guided order instead of a list, the Start Here learning path walks through four core guides in sequence. When you are ready to go further, Money & Economics explains why people value Bitcoin, and the timeline of milestones gives context for the headlines. Nothing here is investment advice, and Bitcoin's price can fall sharply.

Frequently asked questions about Bitcoin Basics
What is Bitcoin in simple terms?
Bitcoin is a digital money system that runs without a bank or company in charge. Thousands of computers keep identical copies of a public ledger and check every transaction against shared rules. The word also names the unit of money, written bitcoin or BTC. What Is Bitcoin? explains the network, the coin and the main risks in plain English.
Who created Bitcoin?
Bitcoin was created by a person or group using the name Satoshi Nakamoto, whose real identity is unknown. The whitepaper appeared on 31 October 2008 and the first block was created on 3 January 2009. Nakamoto stopped taking part in 2010 and 2011, and nobody has proven a claim to the name. See The History of Bitcoin.
Who owns Bitcoin?
Nobody owns the Bitcoin network. Individual coins belong to whoever controls the private keys that can spend them, including individuals, companies, funds and exchanges holding coins for customers. The main software is open source, and rule changes only matter if the people running the network adopt them. What Is Bitcoin? covers ownership and control.
How many bitcoin will ever exist?
Only 21 million bitcoin can ever exist, a limit written into the software. New coins are released on a schedule that halves roughly every four years, and the last are expected around the year 2140. One bitcoin divides into 100 million satoshis, so owning a fraction is normal. Details are in What Is Bitcoin?.
When did Bitcoin start and what are the key milestones?
The network started on 3 January 2009 with the genesis block, after the whitepaper of 31 October 2008. Later milestones include the first halving in November 2012, the 2014 collapse of the Mt. Gox exchange, the SegWit upgrade in August 2017 and US spot Bitcoin ETFs in January 2024. The history timeline places each in context.
Is Bitcoin safe for a beginner?
Bitcoin carries real risks: the price can fall sharply, payments are generally irreversible, lost keys cannot be recovered, no deposit insurance applies and scams target newcomers. Whether it suits you depends on your finances, so learn first and consider a qualified professional. What Is Bitcoin? sets out the risks plainly.
