How many halvings are left?

Four halvings have happened, in November 2012, July 2016, May 2020, and April 2024, and the reward now sits at 3.125 coins per block. The cap is 21 million, with 20,083,115 coins circulating as of 12 September 2026, so under four million remain, issued on a schedule that halves every 210,000 blocks. A total count of future halvings is arithmetic this page does not perform, because the sources behind it state the rule, not a projection.

Why is the halving every four years instead of a gradual decline?

The protocol rule is block-counted, not calendar-counted: the reward halves every 210,000 blocks. At the protocol's intended cadence of about one block per ten minutes, 210,000 blocks works out to roughly four years. The design rationale behind the step shape is not stated in the documents behind this page, so this page does not state it either.

Can You Mine Bitcoin Now? The ASIC Era, on Record

The question behind the short URL

People type mine into a search bar and mean one question. Can they do it, on their hardware, from where they sit. This page answers in documented facts rather than a yes or a no, because the honest yes or no depends on electricity prices and hardware budgets no education page can price for a stranger. The era facts are fixed. They are below, dated and sourced.

The URL’s plainness is inherited. The old page at this address was a stub, thirty-odd words around a video slot, and the research pack recorded it as empty. The question deserved a real page. This is it.

The era you would be entering

The first era ran from 2009. Ordinary processors did the work, and the reward was 50 coins per block. That era has a protocol-dated end. Block 210000, reached on 28 November 2012, halved the reward to 25 coins and closed the opening phase ^[3].

Specialized hardware took over from there. Application-specific integrated circuits, ASICs, have been the dominant mining method since 2013, and they remain dominant today ^[1]. An older version of this family’s copy treated 2021 as the end of the ASIC era. That was the audit’s vintage talking. The era has no recorded end. The hardware evolution page walks the whole ladder, processor to graphics cards to field-programmable chips to ASICs, with the protocol-dated boundaries marked.

The reward you would compete for

Each block pays its winner two streams. The subsidy is 3.125 new coins, the rate set by the fourth halving in April 2024 ^[1]. Transaction fees ride on top, paid by transactors ^[1]. The subsidy is fixed by schedule. The fees are not.

The competition itself is a lottery by design. The protocol’s walkthrough uses the lottery framing to explain what the work buys: no single participant can keep adding blocks one after another ^[4]. Difficulty retargets as participation changes, keeping the cadence near ten minutes ^[4]. More power joins, the work gets harder. That is the shape of the thing a miner enters.

The supply math, dated

The cap is 21 million coins, stated in the FAQ’s own words ^[1]. The circulating count read 20,083,115 coins on 12 September 2026, from a public on-chain endpoint ^[2]. Under four million remain, issued across the halving schedule’s long tail. The next halving is protocol-scheduled, not calendar-pinned, and this page pins nothing.

The four boundaries, on-chain

The halving boundaries are not folklore. Each is a specific block with a timestamp, readable by anyone. Two independent block-data providers returned identical timestamps and hashes for all four ^[3]. Block 210000, 28 November 2012, 15:24:38 UTC. Block 420000, 9 July 2016, 16:46:13 UTC. Block 630000, 11 May 2020, 19:23:43 UTC. Block 840000, 20 April 2024, 00:09:27 UTC. The reward crossed 50 to 25, 25 to 12.5, 12.5 to 6.25, and 6.25 to 3.125 across those four moments ^[3].

The exactness is the point. A reader deciding whether to enter an era deserves to know the era’s boundaries are protocol events, not anniversaries somebody estimates. The dates above are not rounded recollections. They are block reads.

Verifying without joining

Nothing on this page asks a reader to mine in order to check it. The supply endpoint is public ^[2]. The halving blocks are public ^[3]. The protocol’s FAQ, which carries the cap and the schedule, is a public document ^[1]. That openness is the system’s own posture. The FAQ describes the money supply information as readily available on the blockchain for anybody to verify ^[1]. A prospective miner can audit the record before spending a cent on hardware, and this page’s sourcing is built so that auditing it is one click deep.

What this page will not do

Three things sit outside this page by rule. It projects no profitability, because the inputs vary by place and moment. It recommends no hardware, because recommendations are product picks and this library makes none. It predicts no price effect from any halving, past or future. The web is full of all three. This page is the antidote, not the echo.

The honest summary

The documented record supports four sentences. The CPU era ended in 2012 at a protocol-dated block. ASIC hardware has dominated since 2013 and still does. The winner of each block takes 3.125 new coins plus fees. Nobody’s profitability follows from any of those sentences, and anyone who says otherwise is selling something, usually hardware or a course. The facts are free above. The decision is the reader’s own.

Where this page sits

The mining overview holds the schedule and the supply count in full. The explainer holds the consensus mechanism step by step. The hardware history holds the eras. The price page carries the market record with the same dating discipline, and the bitcoin hub is this family’s home root.
