Hyperbitcoinisation: the full picture

• A. A rapid increase in the number of Bitcoin miners worldwide
• B. A hypothetical scenario in which Bitcoin becomes the dominant global monetary system and displaces most fiat currencies ✓
• C. A technical upgrade that increases Bitcoin's transaction throughput
• D. A government policy that mandates Bitcoin as legal tender

Why: Hyperbitcoinisation describes a hypothetical, often rapid, transition in which Bitcoin becomes the primary global store of value and medium of exchange, displacing fiat currencies. It is a speculative future scenario rather than a technical upgrade or policy.

• A. Traditional central bankers and monetary policy committees
• B. Academic economists studying Keynesian models
• C. Bitcoin maximalists and advocates who expect Bitcoin to supplant fiat money ✓
• D. Large commercial banks seeking to integrate blockchain settlement

Why: The term originated and is primarily used within the Bitcoin community, especially among maximalists who believe Bitcoin will eventually replace fiat currencies entirely.

• A. It was coined in a 1930s economics textbook about hyperinflation
• B. It is derived from the 'hyper' prefix, implying an extreme or accelerated version of 'Bitcoinisation,' a term describing Bitcoin's growing adoption ✓
• C. It was introduced by a government regulator in a formal policy paper
• D. It comes from a Greek word meaning 'digital gold'

Why: The word combines 'hyper-' (extreme or rapid) with 'Bitcoinisation' (the spread of Bitcoin use), so it denotes an accelerated, dramatic form of Bitcoin's adoption. The term gained popularity in online Bitcoin communities in the 2010s.

• A. Because Bitcoin cannot be divided into smaller units
• B. Because Bitcoin's price volatility and limited transaction capacity raise doubts about its ability to serve as everyday money at global scale ✓
• C. Because Bitcoin is legally banned in every country
• D. Because Bitcoin transactions are instantaneous and therefore unsuitable for payments

Why: Critics point to Bitcoin's significant price volatility, which undermines its usefulness as a stable unit of account, and to its limited base-layer transaction throughput, questioning whether it could handle global payments at scale.

• A. They are unrelated terms describing different cryptocurrencies
• B. Bitcoinisation refers to a current or gradual increase in Bitcoin adoption, while hyperbitcoinisation refers to an extreme, rapid, and near-total version of that process ✓
• C. Hyperbitcoinisation is the older term, and Bitcoinisation was coined later to describe it
• D. Bitcoinisation refers to mining difficulty, while hyperbitcoinisation refers to block size

Why: Bitcoinisation describes the ongoing, gradual spread of Bitcoin use, whereas hyperbitcoinisation is the hypothetical extreme endpoint in which that adoption becomes rapid and dominant, displacing fiat money.

• A. 21 million BTC ✓
• B. 100 million BTC
• C. 210 million BTC
• D. Unlimited, with supply controlled by miners

Why: Bitcoin's protocol caps total issuance at 21 million coins. This fixed ceiling is hard-coded into the software and is a core reason many people view bitcoin as a scarce monetary asset.

• A. Every year
• B. Every 2,100 blocks, roughly every four years ✓
• C. Every 10 minutes
• D. Only when governments vote to change it

Why: The block subsidy halves every 210,000 blocks, which corresponds to roughly every four years at the target block time of about 10 minutes. Halvings cut the rate of new bitcoin issuance in half each time.

• A. 50 BTC
• B. 25 BTC
• C. 6.25 BTC
• D. 3.125 BTC ✓

Why: The reward started at 50 BTC in 2009, halved to 25 BTC in 2012, to 12.5 BTC in 2016, to 6.25 BTC in 2020, and to 3.125 BTC in April 2024.

• A. It guarantees the price will always rise
• B. It makes bitcoin immune to all forms of market risk
• C. It limits the ability of any authority to inflate the money supply by creating new units ✓
• D. It means transactions are free of fees forever

Why: A predictable, capped supply means no central bank or government can expand the quantity of bitcoin at will. Supporters argue this protects purchasing power over time, unlike fiat currencies that can be increased without limit.

• A. New issuance stays constant forever at 50 BTC per block
• B. New issuance increases with each halving
• C. New issuance decreases geometrically, approaching zero as the supply nears 21 million ✓
• D. New issuance is set annually by a committee of developers

Why: Because the subsidy halves repeatedly, issuance shrinks geometrically. The total supply converges toward 21 million, with the last fraction of a bitcoin mined around the year 2140.

• A. Medium of exchange
• B. Store of value ✓
• C. Unit of account
• D. Legal tender

Why: A store of value is the function of money that allows people to save purchasing power across time. Bitcoin proponents argue its fixed supply of 21 million coins makes it a strong candidate for this role, though its price volatility is a common point of debate.

• A. It can be physically exchanged for goods in a store
• B. It is used to express and compare the prices of goods and services ✓
• C. It is backed by a government guarantee
• D. It can be divided into very small fractions

Why: A unit of account is the measuring stick of value: prices, debts, and contracts are denominated in it. Bitcoin is used as a unit of account in some contexts, such as when merchants list prices in sats or BTC, but most everyday pricing still occurs in national currencies.

• A. Its fixed supply cap of 21 million coins
• B. Its ability to be transferred peer-to-peer without a central intermediary ✓
• C. Its historical price appreciation
• D. Its use of proof-of-stake consensus

Why: A medium of exchange must be transferable in a way that lets buyers and sellers complete trades easily. Bitcoin's peer-to-peer transfer capability allows value to move directly between parties. The fixed supply mainly supports the store-of-value case, and proof-of-stake is not how Bitcoin works.

• A. Volatility makes it impossible to divide Bitcoin into smaller units
• B. Sellers may be reluctant to accept an asset whose value could shift sharply before a transaction settles or before they spend it ✓
• C. Volatility reduces the total number of Bitcoin in circulation
• D. Volatility means Bitcoin cannot be sent across borders

Why: When the value of money changes rapidly, merchants face pricing risk and users may hesitate to spend it, since its purchasing power could drop soon after receipt. This is one reason many merchants convert Bitcoin payments into fiat immediately, limiting its practical use as everyday money.

• A. Bitcoin fully satisfies all three functions equally at present
• B. Bitcoin is widely debated as to how fully it satisfies each function, with its store-of-value role often considered its strongest case ✓
• C. Bitcoin satisfies none of the three functions by definition
• D. Bitcoin only functions as a medium of exchange, never as a store of value

Why: Analysts disagree on how well Bitcoin performs each monetary function. Its supply schedule and scarcity make the store-of-value argument prominent, while its volatility and limited everyday acceptance weaken its medium-of-exchange and unit-of-account roles. Understanding this nuance is central to evaluating hyperbitcoinisation claims.

• A. The discretion of a central bank's board of governors
• B. The amount of gold held in reserve to back the currency at a fixed rate ✓
• C. Voter approval of annual money supply targets
• D. The total value of a nation's exports in the prior year

Why: Under the gold standard, currency was convertible into a fixed quantity of gold, so the monetary base was effectively limited by the gold reserves a country held. This scarcity constraint is a central argument for hard money advocates.

• A. Deflation
• B. Stagflation
• C. Inflation
• D. Disinflation

• A. The Panic of 1907
• B. The Bretton Woods Conference of 1944
• C. Executive Order 6102 in 1933 and the Gold Reserve Act of 1934 ✓
• D. The Nixon Shock of 1971

Why: In 1933 Franklin Roosevelt's Executive Order 6102 required citizens to surrender gold coins and certificates to the Federal Reserve, and the Gold Reserve Act of 1934 fixed the gold price at $35 per ounce while restricting private gold ownership. The 1971 Nixon Shock ended international convertibility for foreign governments.

• A. Steady erosion of purchasing power
• B. Relative stability or gradual appreciation of purchasing power ✓
• C. Rapid, predictable doubling every decade
• D. No measurable effect, since prices are set by producers alone

Why: When the money supply cannot be expanded at will, real purchasing power tends to hold steady or rise as productivity grows and goods become cheaper in money terms. Advocates contrast this with fiat systems where expanding money supply tends to erode savings over time.

• A. Good money always drives bad money out of circulation
• B. When two forms of money have a fixed legal exchange rate, the overvalued money tends to drive the undervalued money out of circulation ✓
• C. Central banks must raise interest rates when unemployment falls
• D. Inflation always precedes a sovereign debt default

Why: Gresham's law states that if two monies are forced to exchange at a fixed legal ratio despite differing metal content or value, people hoard the more valuable one and spend the less valuable one, so bad money drives out good. The popular phrasing 'bad money drives out good' is a simplification of this.

• A. The process of issuing a currency in a fixed, unchangeable supply
• B. The reduction in a currency's purchasing power, often caused by an increase in its money supply
• C. A government revaluing its currency upward against foreign currencies
• D. The removal of a currency from circulation after a central bank redesign

• A. A sustained decrease in the general price level across an economy
• B. A sustained increase in the general price level, reducing purchasing power over time
• C. A temporary spike in the price of a single commodity
• D. A fixed exchange rate between two national currencies

• A. Its issuers can adjust the supply at will through central bank policy
• B. The protocol caps total issuance at 21 million coins, which cannot be changed by any single party
• C. Its supply is pegged to the price of gold
• D. Miners are limited to a fixed number of coins per year by government licence

• A. A guaranteed return on a government bond
• B. An asset or strategy intended to preserve value when another asset loses value, such as during inflation
• C. A tax levied on savings accounts to offset inflation
• D. A loan taken out to finance speculative trading

• A. Its price is set daily by a central authority
• B. Its supply schedule is predictable and not controlled by a central bank
• C. It pays a fixed interest rate to holders
• D. It is legal tender in every country

• A. Institutional adoption relies on individuals holding small amounts in self-custody, while retail adoption involves banks and funds holding large reserves.
• B. Institutional adoption is driven by large organizations such as companies, funds, and banks allocating capital to Bitcoin, while retail adoption is driven by individual users buying and holding it directly.
• C. Institutional adoption requires government legislation, while retail adoption requires only a smartphone and internet access.
• D. Institutional adoption and retail adoption are identical in mechanism but differ only in the currency used for settlement.

• A. A central bank printing Bitcoin-denominated bonds to fund national debt.
• B. A national government or state entity holding Bitcoin as a reserve asset or recognizing it as legal tender or an official asset class.
• C. Individual citizens voting in referendums to approve the use of Bitcoin in their private transactions.
• D. A private company registering its ownership of Bitcoin with a national stock exchange.

• A. El Salvador adopting Bitcoin as legal tender in 2021.
• B. Japan banning all cryptocurrency exchanges in 2015.
• C. Germany issuing a digital euro backed by gold reserves.
• D. Switzerland replacing the franc with a stablecoin pegged to the dollar.

• A. Mandatory purchases by central banks for monetary policy operations.
• B. Access to user-friendly wallets, exchanges, and mobile apps that lower the barrier to buying and holding Bitcoin.
• C. Requirements that all employers pay salaries exclusively in Bitcoin.
• D. Elimination of all price volatility through government price controls.

• A. Regulated vehicles are required by Bitcoin's protocol for any transaction above a set size.
• B. Regulated vehicles offer compliance, custody standards, and familiar operational frameworks that fit institutional governance and reporting requirements.
• C. Self-custody is illegal for any entity holding more than one bitcoin.
• D. Regulated vehicles guarantee a fixed return that eliminates market risk entirely.

• A. Excessive inflation caused by central bank printing
• B. Deflationary pressure that could discourage spending and increase the real burden of debt ✓
• C. Immediate loss of all monetary value due to hacking of the network
• D. Unlimited growth in the number of bitcoins in circulation

Why: Because Bitcoin's supply is capped at 21 million coins and issuance is programmatically decreasing, critics argue that a Bitcoin standard could produce persistent deflation. Deflation can encourage hoarding over spending and raise the real value of debts, which can strain borrowers and the economy.

• A. Its volatility makes it difficult to price goods and contracts stably in the short term ✓
• B. Its volatility guarantees that prices never change
• C. Its volatility has no effect on prices because it is used only for savings
• D. Its volatility makes it impossible to store any value over time

Why: A unit of account needs stable purchasing power to set prices and write contracts. Bitcoin's historically high volatility against goods and services makes posting prices and long-term contracts harder, which is one of the main objections raised against it serving as everyday money.

• A. Miners will be paid entirely in fiat currency
• B. Block rewards may decline over time, and fee revenue may not be sufficient to sustain the security budget ✓
• C. Transaction fees will eliminate the need for miners
• D. Fees will make the network faster without any trade-offs

Why: Bitcoin's block subsidy halves roughly every four years, so long term security depends on transaction fees replacing subsidy revenue. Critics question whether fee demand will be large enough to keep the hash rate and network security at adequate levels.

• A. Whether a fixed supply can adjust to growth in goods and services without monetary tools to respond to recessions ✓
• B. Whether Bitcoin will stop functioning when the economy grows
• C. Whether output and money supply must always move in exactly the same ratio by law
• D. Whether governments are required to print money during expansions

Why: Under a fixed-supply monetary system, central banks cannot expand money in response to recessions or financial crises. Critics ask how an economy would absorb shocks, such as falling demand or banking stress, without the countercyclical tools that a flexible money supply provides.

• A. Bitcoin's price rises steadily but never exceeds one dollar
• B. Bitcoin becomes the dominant global monetary asset and the transition could cause large disruptions to existing currencies and institutions ✓
• C. Bitcoin is banned in every country within a single year
• D. Bitcoin replaces gold as the only metal used in jewelry

Why: Hyperbitcoinisation refers to a scenario in which Bitcoin becomes the dominant global money. Open questions include whether such a transition is plausible, how quickly it might happen, and what disruptions it would cause for existing currencies, governments, and financial institutions.
