ECONSOURCE-LED TOPIC GUIDE
Distinguish issuance rules, bank-money creation and economic reasoning about scarcity, incentives or value. A verifiable limit is not a price forecast.
New issuance corresponds to the subsidy component of the block reward, whose permitted amount gradually declines. Under consensus rules, total issuance will not exceed 21 million BTC; transaction fees only transfer existing bitcoin. A bank deposit is a claim on a commercial bank. Cash and central bank reserves are other forms of money; fiat money does not mean only paper banknotes. A commercial bank typically creates a matching deposit when it grants a loan; repayment of principal destroys such deposit money. A central bank creates reserves through a different mechanism. The quantity of money also depends on the chosen aggregate definition.
An issuance cap does not guarantee bitcoin's purchasing power or price growth. Bank deposit creation is not unlimited either: credit risk, capital, liquidity, regulation and monetary policy constrain it. None of these properties alone determines suitable custody or investment for a particular person. The banking sources describe the United Kingdom and euro area; local rules vary. Bitcoin Core v29.0 is an implementation example, not a claim to be the latest version. Linked entries have their own sources and reviews.
A curated path from first principles to the details that matter.
Bitcoin’s issuance cap is the consensus result of a block subsidy that halves every 210,000 blocks and integer satoshi arithmetic. Validating nodes reject a coinbase output above subsidy plus transaction fees; cumulative issuance approaches but stays below 21 million BTC.
The programmed 50% reduction in Bitcoin’s block subsidy every 210,000 blocks.
Central-bank money consisting mainly of currency in circulation plus reserve balances held by banks.
An asset used to transfer purchasing power through time, subject to price, custody, dilution and liquidity risks.
Menger's idea of how easily a good can be exchanged near its prevailing price across scales, places and time.
A form of network effect in which a monetary asset or payment system becomes more useful as more counterparties accept and hold it.
