Bitcoin Miners Face Steeper Climb to 2028 Halving as Costs Rise and Margins Shrink
With block rewards set to fall to 1.5625 BTC in 2028, mining operators are already selling reserves, locking in long-term power deals and diversifying beyond pure Bitcoin mining to survive the next issuance cut.
Bitcoin's fifth halving, expected in April 2028, is shaping up to be significantly more punishing for miners than the 2024 event, as record-high hashrates, elevated energy costs and tighter capital markets compress already thin margins [1].
Several major operators have begun liquidating holdings ahead of the cycle. MARA Holdings sold more than 15,000 BTC in March to reduce leverage, Riot Platforms offloaded over 3,700 BTC in Q1, and Bitdeer reported its Bitcoin holdings had reached zero as of late February [1].
Industry executives say the environment demands a fundamental rethink. Cango's Juliet Ye described a widening efficiency gap that is forcing fleet upgrades and a move toward multi-region energy contracts, warning that operators lacking scale and diversification will struggle. GoMining CEO Mark Zalan argued that "capital discipline now matters more than hashrate maximalism" [1].
Business models are evolving accordingly. Miners are increasingly eyeing revenue from grid services, heat reuse and high-performance compute contracts alongside block rewards. Facilities capable of toggling between AI workloads and hashpower are already attracting premium valuations from investors [1].
Regulatory clarity — including the EU's MiCA framework and expanding U.S. custody rules — is also accelerating institutional capital flows into the sector, with Zalan suggesting the market has yet to fully price in the 2028 supply shock [1].
