The next Bitcoin halving is expected around April 2028, when the network reaches block 1,050,000. At that block, the new-Bitcoin subsidy paid to the miner of a block falls from 3.125 BTC to 1.5625 BTC. The rule is based on block height—not a fixed calendar date. Bitcoin Core’s mainnet consensus parameters specify a subsidy-halving interval of 210,000 blocks. Public countdowns, including CoinWarz, currently place the event near mid-April 2028; their day estimates can change as mining speed and difficulty evolve.
The 2028 halving does not cut the Bitcoin already held by users in half, and it does not guarantee a price increase. It reduces the flow of newly created coins. The immediate economic pressure falls on miners, whose block-subsidy income drops by 50% in BTC terms before accounting for transaction fees, changes in the BTC price, mining difficulty, electricity, or equipment efficiency.

| Question | Answer |
|---|---|
| Trigger | Bitcoin block 1,050,000 |
| Expected calendar timing | Around April 2028; not fixed |
| Subsidy before | 3.125 BTC per block |
| Subsidy after | 1.5625 BTC per block |
| Percentage reduction | 50% of block subsidy |
| Halving interval | Every 210,000 blocks |
| Coins already circulating | Not reduced by halving |
| Transaction fees | Still added to subsidy; not automatically halved |
| Miner revenue in BTC | Depends on subsidy plus transaction fees |
| Price outcome | Not determined by the subsidy code |
The most reliable invariant is the trigger height. Any website providing an exact day, hour, minute, or countdown is estimating when that height will be reached. Its precision is not the same thing as certainty.
What is the Bitcoin halving?
Bitcoin mining rewards include the block subsidy—new coins created according to consensus rules—and transaction fees paid by the transactions included in a block. Approximately every 210,000 blocks, the subsidy for a valid new block is divided by two.
The halving mechanism is not a discretionary monetary-policy meeting. A miner cannot claim the old subsidy after the activation height and expect that block to be accepted by correctly validating nodes. The rule is implemented in Bitcoin’s consensus software and can be independently checked against its source.
The historical 2024 event reduced the subsidy from 6.25 to 3.125 BTC at height 840,000. In 2028 the next step reduces it to 1.5625 BTC at 1,050,000. In the next cycle, the projected 2032 halving will reduce it to 0.78125 BTC at height 1,260,000.
These figures refer to the subsidy, not a guarantee about a miner’s total payout. Transaction fees are additional and vary with demand for blockspace.
Why is the halving expected in April 2028?
Bitcoin targets an average block interval of ten minutes. About 144 blocks at that target correspond to one day. At that average, 210,000 blocks represent roughly 1,458 days, or just under four years. But real blocks are discovered unpredictably, not every 600 seconds on schedule.
The network adjusts mining difficulty periodically to keep its average block time near the target, but changing hash rate can speed up or slow down blocks between adjustments. More miners or more efficient hardware do not instantly change the halving’s block height; they can change its estimated calendar arrival.
As checked on October 7, 2026, the CoinWarz 2028 countdown estimated April 14, 2028. This is a dated estimate, not an announcement from Bitcoin developers or an onchain event date. Other countdown services may disagree by days or more.
BTC-Pulse’s existing Bitcoin mining-difficulty guide explains why a network that produces blocks probabilistically still has a fairly predictable long-run issuance schedule.
How the block subsidy is calculated
The BIP-42 reference describes the subsidy-halving behavior and the technical correction that keeps the schedule bounded. Bitcoin Core performs an integer right shift based on the number of completed 210,000-block intervals.
At genesis, the subsidy began at 50 BTC. The sequence of halvings proceeds: 25, 12.5, 6.25, 3.125, 1.5625, and so on as the number of completed intervals rises. Smaller quantities eventually reach zero because Bitcoin measures value in indivisible satoshis.
The broad maximum of approximately 21 million BTC follows from this declining geometric issuance schedule, allowing for technical details of implementation and historical blocks. The schedule is not a future discretionary printing plan that can be accelerated by an exchange or a miner.
Bitcoin subsidy schedule: 2024, 2028, 2032
Scroll the table horizontally to see all columns.
| Epoch starting height | Approximate cycle | Subsidy per block | Approx. new BTC/day at 144 blocks | Approx. new BTC/year at 365 days |
|---|---|---|---|---|
| 840,000 | 2024 | 3.125 | 450 | 164,250 |
| 1,050,000 | 2028 | 1.5625 | 225 | 82,125 |
| 1,260,000 | ~2032 | 0.78125 | 112.5 | 41,062.5 |
The last two columns are illustrative expected averages derived from 144 blocks per day. Actual calendar-day block counts can differ. Their annual totals are not promises about the number of blocks found in one specific calendar year.
This table separates a fixed consensus amount per valid block from the uncertain number of blocks mined over a period of clock time.
What exactly falls by 50%?
The new-coin component of a block reward falls. Existing balances do not. A wallet holding 0.2 BTC before the halving still holds 0.2 BTC after it, unless the owner spends or receives funds in the meantime.
Transaction fees are not cut in half by the halving rule. If users pay 0.1 BTC in aggregate fees to include transactions in a particular block, those fees remain available to the block’s miner under the normal transaction rules. They change based on blockspace demand and bidding, not the subsidy multiplier.
Miner economics can therefore move by somewhat less or somewhat more than 50% once transaction fees, difficulty, hash rate, BTC price and energy costs are considered. The only exact halving ratio in this context applies to the block subsidy itself.
A worked miner-revenue example
Assume, purely for illustration, that a miner’s block includes 0.10 BTC in transaction fees immediately before and after the halving. Ignore pool fees and assume the BTC price is unchanged.
Before the 2028 halving:
3.125 BTC subsidy + 0.10 BTC fees = 3.225 BTC total block reward
After the 2028 halving:
1.5625 BTC subsidy + 0.10 BTC fees = 1.6625 BTC total block reward
The difference is 1.5625 BTC for each otherwise comparable block. The total reward falls by about 48.45%, not exactly 50%, because the transaction-fee component did not change.
A miner’s total block revenue includes transaction fees as well as the subsidy. If average transaction fees rise sharply, the total reward reduction can be smaller. If fees fall, the miner could face an even greater revenue squeeze than the subsidy alone suggests.
How much fee revenue would replace the subsidy cut?
Continue the same example with 0.10 BTC in pre-halving fees. To restore total per-block revenue of 3.225 BTC after the halving, transaction fees would need to reach:
required fees = 3.225 − 1.5625 = 1.6625 BTC per block
That is a jump from 0.10 BTC to 1.6625 BTC in this hypothetical case. It illustrates how much fee demand would be needed to offset the missing new issuance if the Bitcoin price and other inputs remained constant.
Nobody should read this as a forecast that fees will reach 1.6625 BTC. Actual fees depend on blockspace demand, transaction composition and the market for inclusion. It is a stress-test calculation showing that fee substitution is not automatically easy.
Our Bitcoin fees and mempool guide explains how user demand for transactions affects miner fee income.
What happens to Bitcoin’s new supply?
At 144 expected blocks per day, 3.125 BTC per block corresponds to around 450 BTC of new supply per day before the event. After the subsidy falls to 1.5625 BTC, that rate becomes about 225 BTC per day.
The approximate difference is 225 BTC per day, or 82,125 BTC across a hypothetical 365-day period at the target average block cadence. This is a flow comparison, not a claim that anyone burns or removes 82,125 BTC of existing coins.
The economic consequence depends on the market’s appetite to buy and hold new supply, miners’ selling strategies, treasury acquisitions, derivative hedging, exchange inventories and broader monetary conditions. A smaller newly created flow can matter without mechanically forcing any particular spot price.
A miner may also sell less or more than newly mined rewards depending on financing, working capital and treasury policy. Miner distribution is not identical to issuance.
How do Bitcoin miners respond?
A miner’s short-term economics depend on hash price, electricity cost, equipment efficiency, facility overhead, pool fees and the BTC-denominated reward available for the hash power contributed.
The subsidy cut can reduce revenue per unit of hash power if all else is constant. Less efficient machines may become unprofitable first, prompting miners to shut them down, move to cheaper energy or upgrade equipment. Others may hedge future production or seek additional revenue from hosting AI and high-performance-computing workloads.
BTC-Pulse has reported on public miners shifting capacity toward AI and HPC. That article illustrates an existing business response to mining economics; it does not prove what miners will do in 2028.
If some miners leave the network and hash rate falls, blocks may temporarily arrive more slowly until difficulty readjusts. The network’s rules do not change the halving height to protect miners from lower profitability.
Why difficulty adjustment matters after the halving
Bitcoin adjusts mining difficulty approximately every 2,016 blocks. When hash rate changes, the adjustment helps restore the average ten-minute block interval over time. This is distinct from the halving, which changes the subsidy every 210,000 blocks.
The two schedules interact economically. Lower mining revenue can change how many machines operate, which changes effective hash rate and then difficulty. Difficulty may decline if substantial hash power exits, improving the relative position of miners that continue operating.
However, difficulty adjustment is not a bailout. It does not guarantee every miner becomes profitable, and it can take time for the network to reach a new equilibrium.
Does a Bitcoin halving guarantee a bull market?
No. The subsidy rule says nothing about how much buyers will pay for BTC. Historically, halvings have occurred during broader cycles of liquidity, credit, institutional access, mining technology and market participation.
It is tempting to attribute every subsequent price rally solely to a halving. That oversimplifies causality. Other variables include global interest rates, macro liquidity, ETF flows, risk appetite, exchange leverage, regulation and the BTC price that miners require to fund operations.
Another common error is claiming that the market receives no warning. The height and schedule have been public for years. Traders can price expectations ahead of the event, and the actual price reaction can differ sharply from predictions.
The supply rule is known; future demand and valuation remain uncertain.
Three scenarios for the 2028 mining market
Scroll the table horizontally to see all columns.
| Scenario | Miner-side conditions | What to watch | What it does not prove |
|---|---|---|---|
| Stress | BTC price weak, fees low, energy expensive | Hash-rate exits, difficulty adjustment, listed-miner liquidity | Automatic network collapse |
| Adaptation | Some inefficient capacity exits, efficient fleets expand | Fleet efficiency, power agreements, pooled revenue | Guaranteed BTC rally |
| Fee-supported | Blockspace fees grow substantially | Fees per block, sustained onchain settlement demand | That fees will replace subsidy every day |
These are operational scenarios, not BTC price targets. There is no defensible reason to insert a precise 2028 Bitcoin price into a halving explainer when the query primarily asks for date and supply mechanics.
How to estimate the event using block height
A live Bitcoin node or trustworthy explorer can provide current chain height. Subtract that number from 1,050,000 to get remaining blocks, then divide by a rough expected block count per day for an approximate time estimate.
For example, if the chain were at a hypothetical height of 970,000:
remaining = 1,050,000 − 970,000 = 80,000 blocks
80,000 ÷ 144 ≈ 556 days
This is explicitly a hypothetical example, not a claim about the chain height on October 7, 2026. A real countdown should refresh the current height and recent block-interval estimate, especially if hash rate changes quickly.
A calendar countdown can be helpful for planning, but the activation condition is always the consensus height.
Common mistakes about 2028
“All Bitcoin balances will halve”
False. Only the new subsidy per block halves. Wallet balances remain denominated in the same BTC units.
“The exact halving date is already coded”
False. The block height is coded. Clock time depends on future blocks.
“Transaction fees will also fall 50%”
False. Fees are determined by user demand and transaction rules, not by the subsidy schedule.
“Mining becomes permanently unprofitable”
Not necessarily. Profitability depends on BTC price, fee flow, equipment and power costs, and the difficulty response.
“A price pump must follow within a certain number of days”
The software has no price mechanism. Supply changes can influence incentives, but price remains a market outcome.
“More hash rate moves the halving to an earlier block”
No. The activation height stays at 1,050,000. Faster block production can shift its expected calendar date.
FAQ
What is the Bitcoin halving date in 2028?
There is no final day fixed by consensus. Public countdowns checked October 7, 2026 point approximately to April 2028, with CoinWarz estimating April 14. The event actually occurs at block 1,050,000.
What will the Bitcoin block reward be after the 2028 halving?
The subsidy will be 1.5625 BTC per block, plus whatever transaction fees are included in that block. The total may differ from block to block.
How much new Bitcoin will be mined daily?
At 144 blocks per day on average, roughly 225 BTC of new subsidy after the event, compared with 450 BTC before it. Actual calendar-day totals vary.
Is Bitcoin’s supply cut by half?
The rate of newly minted coins from block subsidies is halved. Existing supply is not cut in half.
When is the next halving after 2028?
The following programmed subsidy interval begins at height 1,260,000, roughly in 2032 if average block timing stays close to target. The subsidy then becomes 0.78125 BTC.
Can the 2028 halving happen before April?
It could. If blocks arrive faster than earlier estimates, the activation day moves earlier; slower block production moves it later.
BTC-Pulse Take
The 2028 halving is most useful as a predictable change in the creation of new BTC and a stress test for miners. Its trigger block is fixed, but the exact date, miner profitability and market price are not.
The practical figures are the 1.5625 BTC post-halving subsidy, the approximate reduction of 225 new BTC per day at target cadence, and the transaction-fee revenue needed to offset that reduction. These can be evaluated without promising a bull market or treating miner fees as guaranteed.
