What is Bitcoin?
Satoshi Nakamoto published the Bitcoin white paper in 2008 and released the first software in 2009. Bitcoin is an open network for transferring scarce digital value without a central issuer. The public ledger records spendable transaction outputs, while private keys authorize new transactions. Independently operated nodes check the same supply and transaction rules, and proof-of-work miners compete to add valid blocks.
The network and the asset are related but not identical. Bitcoin is the protocol and network; bitcoin, measured as BTC or satoshis, is the asset accounted for by that system. A wallet manages the keys used to spend it. An exchange account is a claim on a company until a withdrawal reaches an address controlled by the user.
Bitcoin’s price can move sharply because buyers and sellers meet in separate order books around the world. Scarcity does not guarantee a stable price or a future return. Start with the system, custody, and risks before treating the chart as the whole story.
Read the complete Bitcoin guide →Bitcoin questions, answered quickly
Use the short answer first. Follow the linked evidence when the distinction matters.
Does Bitcoin have one official price?
No. Bitcoin trades on separate venues, so prices can differ. Bitcoin.now publishes a read-only BTC/USD reference from available direct dollar markets and labels its sources and timestamp. Check the source method.
How many satoshis are in one bitcoin?
One bitcoin equals 100,000,000 satoshis. A satoshi, often shortened to sat, is the smallest unit recorded by the Bitcoin protocol. Use the satoshi calculator for exact unit conversions.
Why is Bitcoin limited to 21 million?
Bitcoin nodes independently enforce an issuance schedule whose block subsidy halves every 210,000 blocks. The schedule approaches a maximum of 21 million bitcoin. The supply explorer calculates it by block height.
Can I buy or trade Bitcoin on Bitcoin.now?
No. Bitcoin.now provides education, read-only market references, calculators, and research. It does not open accounts, connect wallets, execute trades, or provide executable quotes. Read the neutral buying due-diligence guide before comparing providers.

I’m new to Bitcoin
Build a correct mental model before you think about buying.
About this path+
Learn what Bitcoin is, how transactions work, what wallets control, and which risks to check before using money.
More information
This path starts with the difference between Bitcoin, bitcoin, a wallet, and an exchange account. It then covers supply, transactions, fees, buying risks, and the first custody choices in a sensible order.
02
I want to protect it
Compare custody and build backups around realistic risks.
About this path+
Compare exchange custody, self-custody, seed backups, hardware wallets, scams, and recovery plans.
More information
This path helps you identify what each key or backup protects, who can authorize a transaction, and how to test recovery safely. It also separates realistic theft and loss risks from security theater.
03
I want the deep mechanics
Follow transactions, blocks, nodes and consensus.
About this path+
Follow a transaction from its signature through node checks, mining, blocks, confirmations, and consensus.
More information
This path connects UTXOs, scripts, the mempool, proof of work, difficulty, block rewards, and chain selection. Each lesson builds on the last so the network becomes one understandable system.
04
I’m reading the market
Understand venues, liquidity, ETFs and risk without hype.
About this path+
Learn how prices form, why USD and USDT differ, and how liquidity, spreads, ETFs, custody, and volatility affect risk.
More information
This path explains why exchanges show different prices, how order books and trading volume can mislead, and what an ETF changes - or does not change. It keeps market observation separate from personal investment advice.
Bitcoin, from first principles.
