How Many Bitcoins Are Mined a Day? Translate Blocks Into a Supply Budget

At Bitcoin’s usual ten-minute target pace, about 450 new BTC are mined in a 24-hour period during the current 3.125-BTC subsidy era. That is 144 expected blocks multiplied by 3.125 BTC each. It is a planning rate, not a promise that exactly 450 BTC appear on every calendar date. The more useful way to apply it is to distinguish a daily shorthand, a month-length estimate and the fixed block budget that governs an entire halving era.

One subsidy rule, several reporting units

Bitcoin issues the subsidy with accepted blocks, not with daily accounting runs. Bit.Fan’s explanation of the per-block daily-mining rule ties the daily estimate to block timing and the current block reward. The Bitcoin.org halving schedule lists 3.125 BTC per block after the April 2024 halving at height 840,000 and an average target of roughly ten minutes per block. Divide 24 hours by ten minutes and you get 144 target-paced blocks, hence 450 BTC.

Writing “450 BTC/day” is a unit conversion from a protocol rule and a target interval. The actual rule is 3.125 BTC of permitted new subsidy per block in this height range. A date with faster or slower block discoveries will contain a different number of blocks. No miner receives a special midnight payment to correct a day that happens to finish above or below the planning rate.

A month estimate must state its month length

A report that says “13,500 BTC per month” silently assumes a 30-day month at 450 BTC per day. For a 28-day February, the same rate gives 12,600 BTC; for 31 days, it gives 13,950 BTC. Those three values are hypothetical target-paced baselines, not observed chain totals. A reader comparing monthly figures should check whether the author used 28, 30 or 31 days before attributing the difference to miners or an issuance change.

The same care applies to annualization. At 450 BTC a day for 365 days, the arithmetic result is 164,250 BTC. A leap year would produce a different calendar multiplier, and a year that crosses the next subsidy halving cannot use 3.125 BTC for every block. The annualized figure is helpful for a rough scale comparison only when its assumptions are printed beside it.

Imagine a planning spreadsheet with “BTC created” as one row. Its formula can use expected blocks per day times the active subsidy times the number of days. Label the cell “target-paced estimate” and include the relevant block-height range. A separate row can later hold observed subsidy from the chain. Combining estimate and observation under one unlabeled number makes revisions look like contradictions when they are simply different methods.

The halving era has a block budget, not a calendar budget

The subsidy remains 3.125 BTC for 210,000 block heights from 840,000 through 1,049,999. If every block claims the full permitted subsidy, that range allows 210,000 multiplied by 3.125, or 656,250 BTC of new issuance. This is a block-count budget for the era. How many calendar days the era lasts depends on actual block timing, so multiplying a four-year guess by 450 BTC/day will not necessarily produce the same exact number.

At height 1,050,000, Bitcoin.org lists the next subsidy as 1.5625 BTC, with the calendar date estimated around 2028. The height is the rule boundary; the date is a projection. A month containing that boundary should divide its accepted blocks into the two subsidy ranges. Multiplying every block in such a month by the old 3.125 rate would overstate the scheduled issuance after the halving.

Reconcile an estimate with chain data

For an observed month, count accepted blocks in the reporting window and apply each block’s subsidy. The Bitcoin developer getblockstats reference describes a per-block subsidy field and a separate totalfee field, both measured in satoshis. Transaction fees are existing BTC paid by users, not extra newly minted supply. A combined block reward display is therefore the wrong column for a new-issuance sum.

A reporting window also needs a declared time zone and date boundary. An explorer’s block timestamps and chain selection may change an early, unsettled count; wait for an accepted history before calling a short window final. If a miner claims less than the full permitted subsidy, a simple block-count times rule calculation is an upper schedule estimate rather than the exact amount claimed. State which measurement you use.

Suppose a hypothetical 30-day period contains 4,280 accepted blocks, all within the current height era and claiming full subsidy. The chain-based schedule result is 4,280 times 3.125, or 13,375 BTC. That is 125 BTC below the 13,500-BTC target-paced month because there were 40 fewer blocks than the 4,320 target count. Nothing about the halving rule changed. This invented block count illustrates reconciliation, not a report on an actual month.

Use the daily figure for the right purpose

About 450 BTC per day is a convenient statement of present target-paced network creation. For calendar planning, multiply it by the correct number of days and warn when a halving may intervene. For a halving-era budget, use 210,000 block heights and the subsidy assigned to those heights. For history, inspect accepted blocks and fees separately. These are three ways to answer how many bitcoins are mined a day at different levels of precision, without pretending a daily estimate is a fixed protocol payout.

Sold Bitcoin but No Cash Yet? Diagnose the Withdrawal Path

Yes, bitcoin can be sold for real money, but a completed BTC sale does not always mean cash is already in your bank. The sale may have created a fiat balance inside a service, while the payout is pending, restricted or unavailable for that account. Find the last completed step before attempting another transfer. That approach is more useful than assuming the bitcoin disappeared or selling again because a bank deposit has not appeared. Locate the balance that actually exists Start in the transaction history. Does it show an incoming BTC deposit, an executed BTC-to-fiat sale, or a submitted fiat withdrawal? Those are separate records. Bit.Fan’s guide to taking bitcoin out for cash explains that a user usually sells BTC first and withdraws the fiat proceeds second. A trading service that supports only the first action cannot complete a bank cash-out for you. Read the asset label carefully. A BTC-to-stablecoin swap gives you a digital token, not automatically dollars at a bank. A sell con...

How Many Bitcoins Have Been Mined? Reproduce the Supply at Any Block

The amount of Bitcoin mined is a moving total tied to the latest valid block. Instead of copying a number that becomes stale, record the block height and calculate the scheduled subsidy for every completed halving era. Then distinguish scheduled issuance from actually created coins, the unspent transaction-output set, coins whose keys may be lost, and BTC currently offered for sale. Define the quantity before counting it The guide to Bitcoin's cumulative mined supply explains the 21 million cap, roughly ten-minute block target, and reward halving every 210,000 blocks. Those rules describe the issuance curve rather than a real-time exchange inventory. “Mined” commonly means BTC created by coinbase transactions in accepted blocks. “Circulating supply” may be a data provider's estimate of issued coins. “Unspent supply” refers to transaction outputs that have not been spent. “Liquid supply” tries to infer which owners may trade. These labels cannot be substituted without stating a...

How to Audit Claims About Polymarket Influencer Marketing

Image
A viral video that shows a large prediction-market win can be an advertisement, a demonstration on a simulated site, or a record of a real trade. Viewers cannot tell which one from a balance animation alone. A sound review preserves the original post, identifies who paid whom, checks the exact market and wallet activity, and keeps allegations clearly attributed until the underlying evidence is verified. Start with what the report actually says The Chinese-language summary of the Wall Street Journal reporting says the newspaper examined influencer videos that allegedly displayed fabricated bets or winnings on sites resembling Polymarket. It also reports claims about U.S.-focused audiences, paid promotion, and videos discussing inside information. These are serious assertions, so a secondary article should name the original reporting and avoid presenting every detail as independently proven. Create a claim table with the quoted allegation, named source, date, evidence cited, response fr...
