Key terms and definitions for Bitcoin market analysis
The highest price a cryptocurrency has ever reached. Bitcoin's ATH is a key psychological and technical level that, once broken, often signals the beginning of a new phase of price discovery.
A market phase where informed investors steadily buy Bitcoin at low prices during periods of low sentiment and volume. Accumulation phases occur at cycle bottoms and precede major bull markets.
Any cryptocurrency other than Bitcoin. Short for "alternative coin," the term encompasses thousands of tokens ranging from major networks like Ethereum to small speculative projects.
A volatility indicator that measures the average range of price movement over a specified period, accounting for gaps. ATR does not indicate direction — it measures how much an asset typically moves.
A trend strength indicator that measures how strong a trend is regardless of its direction, ranging from 0 to 100. Readings above 25 indicate a strong trend, while readings below 20 suggest a weak or absent trend.
The excess return of an investment relative to a benchmark after adjusting for risk. Positive alpha indicates an asset or strategy has outperformed what its risk level would predict.
A prolonged period of declining prices, typically defined as a 20% or greater drop from recent highs. In Bitcoin, bear markets historically last 12-18 months and often follow cycle tops.
The amount of new Bitcoin awarded to miners for successfully adding a block to the blockchain. The reward started at 50 BTC per block and is cut in half approximately every four years through the halving process.
A sustained period of rising prices and positive market sentiment. Bitcoin bull markets have historically been driven by halving-induced supply shocks, lasting 12-18 months and producing exponential gains.
A distributed, immutable ledger that records every Bitcoin transaction in sequential blocks linked by cryptographic hashes. The blockchain enables trustless verification without any central authority.
The average interval between new blocks being added to the blockchain. Bitcoin targets a 10-minute block time, maintained by the difficulty adjustment that recalibrates every 2,016 blocks.
The percentage of total cryptocurrency market capitalization that belongs to Bitcoin. Dominance is a gauge of Bitcoin's relative strength versus altcoins and tends to rise during risk-off periods and fall during speculative altcoin rallies.
Binary CDD simplifies Coin Days Destroyed into a binary signal — either 1 (above average) or 0 (below average) — based on whether the current CDD exceeds its long-term average. Summing this over time reveals sustained periods of heavy or light old-coin movement.
A volatility indicator consisting of a middle moving average band and two outer bands set at standard deviations above and below it. The bands expand during high volatility and contract during low volatility.
The difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask) for Bitcoin. A tighter spread indicates a more liquid and efficient market.
An arbitrage strategy that profits from the price difference between Bitcoin spot and its futures contracts. Traders buy spot Bitcoin and simultaneously sell futures at a premium, earning the spread as the contracts converge at expiration.
A market condition where Bitcoin futures prices are lower than the current spot price, with longer-dated contracts priced progressively lower. Backwardation is unusual for Bitcoin and typically signals extreme bearish sentiment or market stress.
A measure of an asset's sensitivity to market movements, where the market has a beta of 1.0. Bitcoin's beta relative to equities has been significantly above 1.0, indicating it amplifies broader market moves.
An experimental token standard built on Bitcoin using Ordinals inscriptions that allows the creation, minting, and transfer of fungible tokens directly on the Bitcoin blockchain. Named as a nod to Ethereum's ERC-20 standard.
An exchange-traded fund that tracks Bitcoin's price, allowing investors to gain Bitcoin exposure through a traditional brokerage account without directly holding or managing the cryptocurrency. The January 2024 launch of U.S. spot Bitcoin ETFs was a watershed moment for institutional adoption.
A method of storing Bitcoin offline, disconnected from the internet, to protect against hacking and theft. Hardware wallets and paper wallets are common forms of cold storage.
The process of a transaction being included in a block and added to the blockchain. Each subsequent block adds another confirmation, increasing the transaction's security. Six confirmations is widely considered irreversible.
The holding and safekeeping of Bitcoin. Self-custody means you control your own private keys ("not your keys, not your coins"), while third-party custody means an exchange or institution holds them on your behalf.
The process by which all nodes in the Bitcoin network agree on the current state of the blockchain. Bitcoin uses Nakamoto Consensus, combining proof-of-work mining with the longest-chain rule to achieve agreement without a central coordinator.
The phase in a market downturn when remaining holders, including previously convicted long-term investors, surrender and sell at a loss. Capitulation events often mark the final stage of a bear market and historically signal major bottoms.
Coin Days Destroyed (CDD) quantifies the economic weight of Bitcoin transactions by multiplying the number of coins moved by the number of days they were held before moving. It distinguishes between meaningful economic activity and trivial transfers.
A market condition where Bitcoin futures prices are higher than the current spot price, with longer-dated contracts priced progressively higher. Contango is the normal state for Bitcoin futures and reflects positive carry costs and bullish expectations.
The first transaction in every Bitcoin block, created by the miner, which generates new Bitcoin as the block reward plus collects all transaction fees from the block. This is the only way new Bitcoin enters circulation.
A statistical measure ranging from -1 to +1 that describes how closely two assets move together. Bitcoin's low correlation with traditional assets makes it a valuable portfolio diversifier.
A measure of the average change in prices paid by consumers for a basket of goods and services. Rising CPI indicates inflation, which has been cited as both a headwind and a tailwind for Bitcoin depending on the monetary policy response.
An investment strategy where you buy a fixed dollar amount of Bitcoin at regular intervals regardless of price. DCA reduces the impact of volatility and removes the need to time the market.
The distribution of power and control away from a central authority. Bitcoin is decentralized because no single entity controls the network. Thousands of nodes worldwide independently validate transactions and enforce the rules.
The act of attempting to spend the same Bitcoin twice. Bitcoin's proof-of-work consensus mechanism prevents double spending by ensuring the network agrees on a single transaction history.
A market phase where large holders and early-cycle buyers sell their Bitcoin to newer participants at elevated prices. Distribution occurs near cycle tops and precedes major corrections or bear markets.
The Difficulty Ribbon plots multiple simple moving averages of Bitcoin's mining difficulty to visualize miner capitulation. When the ribbons compress, weaker miners are leaving the network, which has historically preceded significant price rallies.
Bitcoin's automatic recalibration of mining difficulty every 2,016 blocks (approximately two weeks) to maintain a consistent 10-minute average block time. It is one of Bitcoin's most critical self-regulating mechanisms.
A measure of the U.S. dollar's value against a basket of six major foreign currencies. DXY strength has historically been inversely correlated with Bitcoin — a weakening dollar tends to coincide with rising Bitcoin prices.
The ratio of a country's total government debt to its gross domestic product. Rising debt-to-GDP ratios globally have strengthened the case for Bitcoin as a hedge against long-term fiscal unsustainability.
A platform where you can buy, sell, and trade Bitcoin and other cryptocurrencies. Centralized exchanges (like Coinbase or Kraken) act as intermediaries, while decentralized exchanges allow peer-to-peer trading.
Entity-Adjusted Dormancy measures the average number of days destroyed per coin transacted, adjusted to account for entities rather than raw addresses. It reveals whether old, long-held coins are waking up and entering circulation.
A type of moving average that places greater weight on the most recent price data, making it more responsive to new information than a simple moving average. Commonly used periods include the 12, 21, 50, and 200-day EMAs.
The set of optimal portfolios that offer the highest expected return for each level of risk. Adding Bitcoin to the investable universe has historically pushed the efficient frontier outward, meaning better risk-return combinations become available.
Fear Of Missing Out. The anxiety-driven impulse to buy an asset because its price is rising rapidly. FOMO often leads to buying near cycle tops and is a powerful driver of late-stage bull market euphoria.
Fear, Uncertainty, and Doubt. Negative or misleading information spread to cause panic selling. FUD is common during bear markets and corrections, often creating buying opportunities for long-term investors.
Financial contracts obligating the buyer to purchase, or the seller to sell, Bitcoin at a predetermined price on a specified future date. Bitcoin futures trade on both crypto exchanges and regulated platforms like the CME.
A sentiment indicator that measures market emotion on a scale from 0 (Extreme Fear) to 100 (Extreme Greed). The index aggregates volatility, volume, social media, surveys, dominance, and trend data to gauge whether the market is fearful or euphoric.
A technical analysis tool that uses horizontal lines at key Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, 78.6%) to identify potential support and resistance levels where price may reverse during a pullback.
A periodic payment exchanged between long and short traders in Bitcoin perpetual futures contracts to keep the contract price aligned with the spot price. Positive funding means longs pay shorts; negative funding means shorts pay longs.
A computer that downloads, validates, and stores the complete Bitcoin blockchain and independently enforces all consensus rules. Full nodes are the backbone of Bitcoin's decentralization, ensuring no one can cheat the system.
The competitive marketplace where Bitcoin users bid transaction fees to have their transactions included in blocks. Because block space is limited, fees rise with demand, creating an auction-like system that prioritizes transactions by fee rate.
The target interest rate set by the Federal Reserve at which banks lend to each other overnight. It is the primary tool for U.S. monetary policy and has a significant influence on Bitcoin through its impact on global liquidity and risk appetite.
An event that occurs approximately every four years (every 210,000 blocks) where the Bitcoin block reward is cut in half. Halvings reduce the rate of new supply entering the market and have historically preceded major bull runs.
A misspelling of "hold" that became a Bitcoin meme and investment philosophy. It means holding Bitcoin long-term through volatility rather than trying to trade short-term price movements.
Hash Ribbons use the crossover of short-term and long-term hash rate moving averages to detect miner capitulation and recovery. A buy signal fires when the 30-day hash rate moving average crosses back above the 60-day, indicating that miner capitulation has ended.
The total computational power being used by miners to process Bitcoin transactions and secure the network, measured in hashes per second. A higher hash rate means greater network security and more competition among miners.
The use of borrowed funds or margin to increase the size of a trading position beyond what the trader's own capital would allow. In Bitcoin markets, leverage up to 100x or more is available on some exchanges.
The forced closure of a leveraged trading position when the trader's losses approach their deposited margin. Liquidations are triggered automatically by exchanges to prevent positions from going into negative equity.
The LTH/STH Supply Ratio compares the amount of Bitcoin held by Long-Term Holders (coins unmoved for 155+ days) to Short-Term Holders (coins moved within the last 155 days). It tracks the tug-of-war between accumulation by patient holders and distribution to newer market participants.
The ease with which Bitcoin can be bought or sold at stable prices without causing significant price movement. High liquidity means large trades can execute with minimal impact on the market price.
A layer-2 payment network built on top of Bitcoin that enables near-instant, low-cost transactions by conducting them off-chain through payment channels. Only the opening and closing of channels are recorded on the main blockchain.
The total market value of all Bitcoin in circulation, calculated by multiplying the current price by the total number of mined coins. Market cap is used to compare Bitcoin's size relative to other assets.
A ratio of Bitcoin's current price to its 200-day moving average. Values below 1.0 suggest undervaluation relative to the long-term trend, while values above 2.4 have historically indicated overheated conditions.
The process of using computational power to validate transactions and add new blocks to the Bitcoin blockchain. Miners are rewarded with newly minted Bitcoin (the block reward) plus transaction fees.
A metric comparing Bitcoin's market value (current price times supply) to its realized value (the value of all coins at the price they last moved). Extreme high readings signal overvaluation; low or negative readings signal undervaluation.
A trend-following momentum indicator that shows the relationship between two exponential moving averages of price. MACD crossovers and histogram changes are used to identify shifts in trend direction and momentum.
A calculation that smooths price data by creating a constantly updated average over a specified number of periods. Moving averages help identify trend direction and act as dynamic support and resistance levels.
The volume of buy and sell orders at various price levels in Bitcoin's order book. Greater market depth means the market can absorb larger trades without significant price impact.
The waiting area where valid but unconfirmed Bitcoin transactions sit before being included in a block by miners. Each full node maintains its own mempool, and transactions compete for block space by offering higher fees.
A group of Bitcoin miners who combine their computational resources and share block rewards proportionally based on each member's contributed hash power. Mining pools reduce the variance of mining income for individual participants.
A cryptographic data structure used in Bitcoin to efficiently summarize and verify all transactions in a block. The Merkle root — a single hash at the top of the tree — is included in the block header and allows any transaction to be verified without downloading the entire block.
The largest peak-to-trough decline in an asset's price over a specific period. Bitcoin has historically experienced max drawdowns of 70-85% during bear markets, making it a critical risk metric for position sizing.
A framework developed by Harry Markowitz that demonstrates how investors can construct portfolios to maximize expected return for a given level of risk through diversification. Adding Bitcoin to traditional portfolios has historically improved the efficient frontier.
A computational technique that models the probability of different outcomes by running thousands of random simulations. Applied to Bitcoin, it helps estimate the range of possible future prices and portfolio values under uncertainty.
A measure of the total money supply that includes cash, checking deposits, savings deposits, money market securities, and other near-money assets. Expansion of M2 has historically been a bullish catalyst for Bitcoin as more dollars chase scarce assets.
The rate at which money circulates through the economy, calculated as GDP divided by the money supply. Declining money velocity suggests that newly created money is being hoarded rather than spent, often flowing into financial assets including Bitcoin.
A computer running Bitcoin software that validates transactions and blocks, enforces consensus rules, and relays data across the network. Running a full node is the most sovereign way to interact with Bitcoin.
The NVT (Network Value to Transactions) Ratio compares Bitcoin's market capitalization to its daily on-chain transaction volume. It functions similarly to a P/E ratio in traditional finance, measuring whether the network is overvalued or undervalued relative to its economic throughput.
NUPL measures the difference between Bitcoin's market cap and realized cap as a proportion of market cap, representing the aggregate unrealized profit or loss of all holders. It ranges from euphoria at the top to capitulation at the bottom.
Data and transactions recorded directly on the Bitcoin blockchain. On-chain analysis examines blockchain data (addresses, transaction volumes, coin age) to derive insights about network health and investor behavior.
A cumulative momentum indicator that adds volume on up days and subtracts volume on down days. OBV reveals whether volume is flowing into or out of an asset, often leading price moves.
A real-time list of all open buy and sell orders for Bitcoin on an exchange, organized by price level. The order book reveals the supply and demand dynamics at each price point.
The total number of outstanding Bitcoin derivative contracts (futures or options) that have not been settled or closed. Rising open interest indicates new money flowing into the market, while falling open interest suggests positions are being unwound.
A protocol that enables inscribing arbitrary data — images, text, audio, or code — directly onto individual satoshis (the smallest unit of Bitcoin). Ordinals brought NFT-like functionality to Bitcoin without requiring changes to the core protocol.
A technical indicator using the 111-day and 350-day (x2) moving averages. When the shorter average crosses above the longer one, it has historically signaled Bitcoin cycle tops with remarkable accuracy.
A mathematical model describing Bitcoin's price as a function of time. On a log-log scale, Bitcoin's price history forms a straight line, producing support and resistance bands useful for identifying long-term value zones.
A secret cryptographic key that proves ownership of Bitcoin and authorizes transactions. Losing your private key means losing access to your Bitcoin permanently. It should never be shared with anyone.
A cryptographic key derived from a private key that can be shared openly. In Bitcoin, public keys are used to generate addresses and verify that transactions were authorized by the corresponding private key holder.
The Puell Multiple divides the daily issuance value of Bitcoin (in USD) by its 365-day moving average. It measures whether miners are earning significantly more or less than their yearly average, highlighting potential cycle extremes.
A trend-following indicator that places dots above or below price to indicate potential reversal points. SAR stands for "Stop and Reverse" — when the dots flip from below to above price, it signals a shift from bullish to bearish, and vice versa.
Bitcoin's consensus mechanism in which miners expend computational energy to find a valid block hash that meets the current difficulty target. Proof of work secures the network by making it prohibitively expensive to alter the blockchain's history.
The aggregate value of all Bitcoin calculated using the price at which each coin last moved on-chain, rather than the current market price. It represents the total cost basis of all holders and is a key input to the MVRV Z-Score.
A price level where selling pressure tends to outweigh buying pressure, preventing the price from rising further. In cycle analysis, resistance bands mark historically overheated zones where corrections are more likely.
Realized Cap values each Bitcoin at the price it last moved on-chain rather than at the current market price. It represents the aggregate cost basis of all coins in circulation and serves as a more grounded measure of capital invested in the network.
Reserve Risk measures the confidence of long-term holders relative to Bitcoin's current price. Low Reserve Risk indicates high holder conviction at a low price, representing an attractive risk-reward entry, while high Reserve Risk signals the opposite.
A momentum oscillator that measures the speed and magnitude of recent price changes on a scale from 0 to 100. Readings above 70 indicate overbought conditions, while readings below 30 suggest oversold conditions.
A metric that evaluates an investment's return relative to the amount of risk taken to achieve it. Bitcoin's risk-adjusted returns have historically outperformed most traditional assets over multi-year horizons despite higher absolute volatility.
The process of periodically adjusting portfolio weights back to target allocations by selling overweight assets and buying underweight ones. For portfolios containing Bitcoin, rebalancing acts as a systematic buy-low-sell-high mechanism.
The interest rate adjusted for inflation, calculated as the nominal interest rate minus the inflation rate. Negative real rates have historically been one of the strongest macro tailwinds for Bitcoin as they incentivize moving into scarce assets.
The smallest unit of Bitcoin, equal to 0.00000001 BTC (one hundred-millionth). Named after Bitcoin's creator, Satoshi Nakamoto. As Bitcoin's price rises, "stacking sats" has become a popular way to think about accumulation.
A set of 12 or 24 words that serves as a human-readable backup of your private keys. With your seed phrase, you can recover your entire Bitcoin wallet on any compatible device. It must be stored securely offline.
A price level where buying pressure tends to outweigh selling pressure, preventing the price from falling further. In cycle models like the Power Law, support bands indicate historically undervalued zones.
The pseudonymous creator of Bitcoin who published the whitepaper in 2008 and released the first software client in 2009. Satoshi's true identity remains unknown, and they are estimated to hold approximately 1 million BTC from early mining.
Bitcoin's hard-coded maximum supply of 21 million coins. This fixed limit, enforced by the protocol's consensus rules, makes Bitcoin the first provably scarce digital asset.
The current market price of Bitcoin for immediate delivery. The spot price is determined in real time by supply and demand across cryptocurrency exchanges worldwide.
A valuation model that prices Bitcoin based on its scarcity by dividing the existing supply (stock) by the annual production (flow). The model, popularized by analyst PlanB, suggests Bitcoin's price should increase after each halving as the flow is reduced.
A cryptocurrency designed to maintain a stable value relative to a reference asset, typically the US dollar. Major stablecoins like USDT (Tether) and USDC serve as the primary on-ramp and trading pair in cryptocurrency markets.
SOPR measures the profit ratio of coins moved on-chain by dividing the realized value of spent outputs by their value at creation. A SOPR above 1 means coins are moving at a profit on average, while below 1 means they are moving at a loss.
Spent Output Age Bands (SOAB) categorize all Bitcoin transactions by the age of the coins being spent, showing what percentage of daily volume comes from coins held for different durations. They reveal the spending behavior of short-term and long-term holders over time.
Supply in Profit/Loss measures the percentage of Bitcoin's circulating supply that is currently worth more (in profit) or less (at a loss) than its last on-chain transaction price. It provides a direct gauge of aggregate holder sentiment and market cycle positioning.
Price levels where buying pressure (support) or selling pressure (resistance) has historically been strong enough to halt or reverse a move. These levels form the foundation of most technical analysis strategies.
A momentum indicator that compares a closing price to a range of prices over a specified period, generating a value between 0 and 100. Readings above 80 indicate overbought conditions and below 20 indicate oversold.
The difference between the expected price of a Bitcoin trade and the actual execution price. Slippage occurs when market conditions shift between the time an order is placed and when it fills.
A Bitcoin protocol upgrade activated in August 2017 that separates (segregates) transaction signature data (witness) from the transaction data. SegWit fixed transaction malleability and effectively increased block capacity.
Bitcoin's simple, stack-based programming language used to define the conditions under which Bitcoin can be spent. Every Bitcoin transaction contains a script that specifies who can claim the funds and under what circumstances.
A measure of risk-adjusted return that calculates how much excess return an investment generates per unit of total volatility. A higher Sharpe Ratio indicates better compensation for the risk taken.
A variation of the Sharpe Ratio that only penalizes downside volatility rather than total volatility. It provides a more accurate risk-adjusted measure for assets like Bitcoin that have asymmetric return distributions.
A statistical measure of the amount of variation in a set of values. In investing, it quantifies the dispersion of returns around the mean and serves as the primary input for calculating volatility and the Sharpe Ratio.
Two different structures for Bitcoin exchange-traded funds: spot ETFs hold actual Bitcoin, while futures ETFs hold Bitcoin futures contracts. Spot ETFs provide more accurate price tracking and do not suffer from the "roll cost" drag that affects futures-based products.
A small amount of Bitcoin paid to miners for including a transaction in a block. Fees are determined by market demand for block space and serve as an incentive for miners alongside the block reward.
Thermocap measures the total revenue paid to Bitcoin miners since the genesis block, calculated as the cumulative sum of all block rewards and transaction fees in USD terms. It represents the minimum cost of producing all existing Bitcoin.
A major Bitcoin protocol upgrade activated in November 2021 that introduced Schnorr signatures, improved smart contract capabilities, and enhanced privacy by making complex transactions look identical to simple ones on-chain.
An alternative name for the Bitcoin blockchain, emphasizing its function as a chronological chain of timestamped blocks. The term was used by Satoshi Nakamoto in early Bitcoin source code and highlights the temporal ordering that gives Bitcoin its integrity.
The return earned on U.S. government bonds of various maturities. Treasury yields represent the risk-free rate of return and serve as the benchmark against which all other investments, including Bitcoin, are compared.
A charting tool that displays the amount of trading volume at specific price levels over a given period. It reveals where the most and least trading activity occurred, highlighting key support, resistance, and fair value zones.
An intraday benchmark that calculates the average price of an asset weighted by volume. VWAP shows the true average price at which trading occurred, making it a key reference for institutional traders.
A statistical measure of the dispersion of returns, typically expressed as annualized standard deviation. Bitcoin's volatility has historically been 3-5 times higher than the S&P 500 but has been trending downward over time.
A statistical measure that estimates the maximum potential loss of an investment over a specific time period at a given confidence level. For Bitcoin, VaR quantifies worst-case scenarios to help with position sizing and risk management.
Software or hardware that stores your private keys and allows you to send and receive Bitcoin. Wallets do not actually store Bitcoin itself; they store the keys needed to access your coins on the blockchain.
An individual or entity holding a very large amount of Bitcoin. Whale movements (large on-chain transfers or exchange deposits) are closely watched because they can significantly impact market price and sentiment.
The original document titled "Bitcoin: A Peer-to-Peer Electronic Cash System" published by Satoshi Nakamoto on October 31, 2008. It describes the design of a decentralized digital currency that solves the double-spending problem without a trusted third party.
An ERC-20 token on Ethereum that represents Bitcoin 1:1, allowing BTC holders to use their Bitcoin in Ethereum's DeFi ecosystem. Each WBTC is backed by one real Bitcoin held in custody by a custodian.
