The Bitcoin network is now more than halfway (50.01%) through its current halving cycle, with the next halving expected on April 12, 2028, just under two years away, according to mempool.space.
This cycle, known as "epoch 5", which began in April 2024 and will continue through to 2028.
A halving occurs every 210,000 blocks, roughly every four years, and reduces the reward miners receive by 50%.
This process controls bitcoin’s issuance and ensures a predictable decline in its inflation rate (currently under 1%). In the current epoch, the block subsidy is 3.125 BTC per block. With blocks mined on average every 10 minutes, around 450 BTC are issued daily.
This 10 minute schedule is maintained through difficulty adjustments, which occur every 2,016 blocks. The network increases or decreases mining difficulty depending on how quickly blocks are found, keeping issuance consistent.
With approximately 104,986 blocks remaining in this cycle, bitcoin’s supply continues its dependable path toward its fixed cap. Each new epoch further reduces issuance and its inflation rate, reinforcing its long term scarcity.
Bitcoin has a fixed maximum supply of 21,000,000 coins, one of its main characteristics which underpins its scarcity. Recently, the network reached a major milestone as the 20 millionth bitcoin was mined, meaning the final million will take another 114 years to mine.
Bitcoin is up around 15% since the April 2024 halving, rising from roughly $64,000 to just under $75,000. Previously reached an all time high of around $126,000 in October 2025 before falling roughly 50% to $60,000 in early February.
However, it has underperformed previous cycles over the same post-halving period, continuing the trend of diminishing returns, according to Glassnode data.
This is largely expected as bitcoin matures, with greater adoption and a larger market cap requiring more capital to drive outsized gains. As a result, volatility is declining each cycle and price action is becoming more gradual compared to earlier cycles.
