What is Bitcoin on-chain activity?
On-chain activity is everything recorded directly on the Bitcoin blockchain: how many addresses are used, how many transactions confirm, how much value moves and how much is paid in fees. Unlike price —which forms on exchanges—, these figures describe actual network usage and anyone can verify them. This tool shows them live next to the price so you can compare both at a glance.
What are unique addresses?
The number of distinct addresses involved in confirmed transactions each day. It is a common activity gauge, with one important caveat: an address is not a person. One user may use many addresses (modern wallets rotate them automatically) and a single address may pool thousands of users (an exchange hot wallet). Read it as a trend, not a user census.
What does the transaction count measure?
Confirmed transactions per day on the chain. A caveat applies here too: large operators bundle many payments into a single transaction (batching), and protocols like Lightning settle thousands of payments off-chain. Even so, its relative evolution —growing or cooling— remains a useful pulse of the network.
What is the estimated on-chain volume?
The total value moved on-chain each day, in US dollars. It is called an estimate because Bitcoin transactions return change to the sender (change outputs), and separating truly transferred value from change requires heuristics. The source (Blockchain.com) applies that estimation consistently, which keeps the series comparable over time.
What are network fees?
Every transaction pays miners a fee to be included in a block, measured in satoshis per vbyte (sat/vB): you pay for the space the transaction occupies, not for its amount. Under congestion fees rise; when the network is quiet, moving any amount can cost cents. The "Sending BTC now costs" card turns the fast rate into actual money: the approximate cost in dollars and euros of a typical ~140 vB transaction (one input, two SegWit outputs); it is an indicative estimate, since the real cost depends on each transaction's size. The mempool card shows the network queue right now (pending transactions and their size in vMB): a large queue explains expensive fees, and an empty one, fees of cents.
What is the hashrate?
The hashrate is the total computing power miners dedicate to securing the network, measured here in exahashes per second (EH/s; 1 EH/s = a quintillion calculations per second). The higher it is, the more expensive it becomes to attack the network, so it is usually read as an indicator of network security and miner investment. It is directly tied to the difficulty adjustment: if the hashrate rises, difficulty will rise at the next adjustment to keep blocks at ~10 minutes. It is protocol-level technical data, with no mechanical short-term relation to price.
What does the price vs activity chart show?
The chart plots the BTC price and the selected on-chain metric over the range you choose (90 days or 1 year), both normalized to their own range (period minimum to maximum) so two series of very different scales fit on the same canvas. The on-chain metric is drawn in two layers: the daily data (thin line) and its 7-day moving average (main line), which filters out the typical weekly pattern of activity —it drops on weekends— and anomalous days, making the trend comparable with the price. Below it, the tool summarizes the situation with percentiles: where today's value sits within each series' own ~90-day range. For example, "price at the 81st percentile, addresses at the 23rd" means the price is higher than 81% of its last ~90 days while network usage sits in the lower part of its range. The gap between both percentiles is a descriptive measure of that separation; it implies no future direction and is not a signal. Analysts historically watch whether price and network usage move together or apart, always alongside many other factors.
What is the difficulty adjustment?
Every 2,016 blocks (about two weeks) Bitcoin adjusts the mining difficulty so blocks keep arriving every ~10 minutes regardless of how much computing power is connected. More miners push difficulty up; disconnections pull it down. The tool shows the real-time estimate of the next adjustment (computed by mempool.space from the current block pace) and when it will happen. It is protocol-level technical data, useful for mining context.
What is the halving?
Every 210,000 blocks (roughly four years), the per-block reward miners receive is cut in half. It is the mechanism that caps Bitcoin's total issuance at 21 million. The tool shows how many blocks remain until the next halving and its estimated date at ~10 minutes per block; the exact date depends on the real mining pace, so the estimate updates continuously.
When is it cheapest to move BTC?
The hour map shows the median fee per block (sat/vB) over the last ~4 weeks, grouped by day of week and hour in your local time. Green cells are the historically cheapest slots and red ones the most expensive; the outline marks the current hour. A 0 is not an error: it marks slots whose blocks were nearly empty and the median fee was literally zero, which is common when the network is very quiet. The typical pattern: the network gets congested during US and European working hours and relaxes overnight and on weekends. It is a statistical guide to the recent past, not a guarantee: a sudden congestion event can change the pattern at any time.
What does the total stablecoin supply measure?
Stablecoins are cryptocurrencies designed to be worth 1 dollar. The total supply is the sum of the market capitalization of all USD-pegged ones: it grows when new units are minted (money enters the ecosystem as tokenized dollars) and shrinks with redemptions. That is why analysts follow it as a gauge of the liquidity available inside the crypto market. The tool shows the current total, its 7- and 30-day change and its ~90-day evolution, along with a breakdown of the largest stablecoins and their mechanism: fiat-backed (dollar and bond reserves), crypto-backed (overcollateralized with crypto assets) or algorithmic. It is a descriptive size-and-composition figure; it implies no market direction.
What is peg deviation (depeg)?
The peg is the 1-dollar anchor. In practice, a stablecoin's market price oscillates slightly around that value (±0.1% is routine: fees and arbitrage friction). The deviation column shows that difference as a percentage, and the color only highlights its magnitude: amber from 0.3% and red from 1%. Large, sustained deviations —so-called depegs— are infrequent but relevant episodes, because they stress-test the coin's backing mechanism. If you enable alerts, your browser can notify you when any top stablecoin exceeds the deviation threshold you set. Showing the deviation is an arithmetic fact; it is not a judgement on any coin nor a recommendation.
Data sources and notice
On-chain series come from the public Blockchain.com API; network status (fees, difficulty, block height) from mempool.space; historical price from the public Binance API; and stablecoin data (supply and prices) from the public DefiLlama API. Daily data may lag the price by one or two days (each card shows the date of its latest data point). This tool shows technical information about the Bitcoin network and the stablecoin market for educational and informational purposes. Nothing shown here constitutes financial advice or an investment recommendation. Trading cryptocurrencies carries a high risk of loss. Each person is responsible for their own decisions.
Frequently asked questions about Bitcoin on-chain data
Do unique addresses equal users?
No. One user may control many addresses (modern wallets rotate them automatically) and a single address may pool thousands of users, such as an exchange wallet. Read them as an activity trend indicator, not a census of people.
How often is the data updated?
Recommended fees, the difficulty adjustment and the block height refresh every few minutes. The daily series (addresses, transactions, volume, dollar fees) are published once a day by the source and may lag by one or two days; each card shows the date of its latest data point.
What does each metric's percentile mean?
It shows where today's value sits within that series' own range over the last ~90 days. An 81st percentile means the current value is higher than 81% of the values in that period. It is a neutral way to put the figure in recent context, with no interpretation of future direction.
Is the on-chain volume exact?
It is an estimate. Bitcoin transactions return change to the sender, and separating truly transferred value from change requires heuristics. The source applies the same method consistently, so the series is comparable over time even if the absolute figure is approximate.
When is it cheapest to move bitcoin?
Historically, the cheapest slots tend to be overnight hours and weekends (green cells on the hour map, shown in your local time), because there is less congestion. It is a statistical pattern from recent weeks, not a guarantee: congestion can change at any moment.
What is Bitcoin's difficulty adjustment?
Every 2,016 blocks (about two weeks) the network recalculates the mining difficulty to keep blocks at ~10 minutes. The next-adjustment estimate shown by the tool is computed from the current block pace and changes in real time until the adjustment block arrives.
What is Bitcoin's hashrate?
It is the total computing power miners dedicate to securing the network, measured in exahashes per second (EH/s). The higher it is, the more expensive attacking the network becomes. It is tied to the difficulty adjustment and is usually read as an indicator of network security and miner investment; it has no mechanical short-term relation to price.
How much does it cost to send bitcoin right now?
The "Sending BTC now costs" card computes it live: it multiplies the current fast rate (sat/vB) by the size of a typical ~140 vB transaction and converts it to dollars and euros at the current price. With a quiet network it is usually under a dollar; under congestion it can multiply. It is an indicative estimate: the real cost depends on your transaction's size, not its amount.
When is the next Bitcoin halving?
The tool shows live how many blocks remain until the next halving (every 210,000 blocks) and the estimated date at ~10 minutes per block. The exact date depends on the real mining pace, so the estimate updates continuously.
Why only Bitcoin and not Ethereum or other networks?
Because Bitcoin is the only network whose historical on-chain data is publicly available, stable and key-free through consolidated sources. Rather than mixing networks with uneven data quality, the tool focuses on doing one well.
Does the price vs activity divergence predict price?
No. The tool describes where each series sits within its recent range and the gap between them; these are arithmetic facts about the past and present, not predictions. Analysts use this kind of data as context alongside many other factors. It does not constitute financial advice.
Why does the stablecoin supply matter?
Because it gauges the tokenized-dollar liquidity available inside the crypto ecosystem: it grows when new units are minted and shrinks with redemptions. It is context data analysts read alongside many other factors; it does not predict any asset's price nor constitute advice.
What does it mean when a stablecoin loses its peg?
That its market price moves away from 1 dollar more than usual. Swings of ±0.1% are routine; large, sustained deviations (depegs) are infrequent episodes that stress-test the coin's backing mechanism. The tool shows each top stablecoin's deviation as an arithmetic fact, without judging any coin.
How do this tool's alerts work?
There are two, both optional: one notifies you when the network's fast fee drops to the threshold you set (handy for moving BTC cheaply) and another when any top stablecoin deviates from its peg by more than the percentage you choose. They work while the tab stays open, via browser notifications, and your settings are saved only in your browser (localStorage): the website receives and stores nothing.
