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 →Build a correct mental model before you think about buying.
Learn what Bitcoin is, how transactions work, what wallets control, and which risks to check before using money.
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.
Compare custody and build backups around realistic risks.
Compare exchange custody, self-custody, seed backups, hardware wallets, scams, and recovery plans.
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.
Follow transactions, blocks, nodes and consensus.
Follow a transaction from its signature through node checks, mining, blocks, confirmations, and consensus.
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.
Understand venues, liquidity, ETFs and risk without hype.
Learn how prices form, why USD and USDT differ, and how liquidity, spreads, ETFs, custody, and volatility affect risk.
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.
Not a company. Not an app. Not merely a chart. Learn how an open network can keep a scarce, shared ledger without a central owner.
