Bitcoin miners are heading into the 2028 halving with tighter margins and higher costs, as block rewards are set to fall to 1.5625 BTC in a more competitive environment.
The shift comes as rising energy prices, record hashrate and stricter regulatory frameworks reduce profitability compared with the 2024 cycle.
Miners including MARA Holdings and Riot Platforms have already begun selling Bitcoin reserves to reduce debt and strengthen balance sheets ahead of the next halving.
Industry participants say the sector is moving away from pure mining models toward energy and infrastructure strategies, including long-term power contracts and diversified revenue streams.
Operators are increasingly exploring additional income from grid services, data centres and AI workloads to offset declining block rewards.
At the same time, clearer regulation in markets such as the US and Europe is attracting institutional capital but also raising operational requirements.
As the 2028 halving approaches, miners that can control costs, secure energy and diversify revenue are expected to outperform in a more demanding market environment.
At the time of reporting, Bitcoin price was $71,212.82.
