The Bitcoin network has officially passed a symbolic milestone, with approximately 100,000 blocks remaining until its fifth halving event, projected to occur around block 1,050,000 in early-to-mid 2028. Based on the average block time of 10 minutes, data providers estimate roughly 700 days remain, placing the halving in April–May 2028. This will reduce the block subsidy from 3.125 BTC to 1.5625 BTC, further tightening the daily new supply from about 450 BTC to roughly 225 BTC.
Halving fundamentals and monetary policy
Bitcoin halvings are hard-coded to automatically cut miner block rewards by 50% every 210,000 blocks. The most recent halving in April 2024 at block height 840,000 dropped rewards from 6.25 BTC to 3.125 BTC. The next halving continues Bitcoin’s deflationary supply model, capping total supply at 21 million coins. Historically, each halving has preceded major bull cycles—2012, 2016, 2020, and 2024 all saw substantial price appreciation in subsequent months—though analysts caution that past patterns may not repeat.
ETF era rewrites the halving playbook
This will be the first full halving cycle dominated by spot Bitcoin exchange-traded funds (ETFs). U.S. spot Bitcoin ETFs now hold well over $100 billion in assets, fundamentally changing market dynamics. Institutional inflows can absorb newly minted coins many times over; for example, a single strong day saw $167 million in ETF inflows, dwarfing the roughly $450 BTC mined daily. Coins sent to long-term wallets, corporate treasuries, and ETFs are locking up circulating supply, leaving exchange reserves at multi-year lows. Some analysts argue the classic four-year “halving cycle” is effectively dead, replaced by an ETF liquidity cycle where macro flows and allocation shifts overshadow the marginal impact of issuance cuts.
Mining industry under pressure
Lower block rewards squeeze miner profitability unless offset by higher Bitcoin prices or transaction fees. After the 2024 halving, large public miners such as Marathon Digital, Riot Platforms, CleanSpark, and Core Scientific accelerated ASIC upgrades and infrastructure expansion. Network hash rate continues to hit new highs, signaling confidence despite rising operational costs. However, transaction fee revenue remains cyclical, and the long-term sustainability of mining revenue after multiple halvings remains an open question.
The milestone reinforces Bitcoin’s narrative as a scarce digital asset with a predictable supply schedule. As the countdown continues, market participants will closely watch whether ETF-driven demand can sustain price action in a landscape where classic supply-shock models may no longer apply.
