Bitcoin miners brace for tighter margins ahead of 2028 halving

The block reward will fall from 3.125 BTC to 1.5625 BTC at the April 2028 halving, cutting miners’ newly issued Bitcoin revenue in half overnight [1]. Unlike the 2024 cut, which occurred when Bitcoin traded near $63,000, the next reduction arrives amid record hashrate, higher energy prices and stricter capital discipline, leaving operators with far less cushion for loss.

Large miners have already begun reshaping balance sheets. MARA Holdings sold more than 15,000 BTC in March, Riot Platforms off‑loaded over 3,700 BTC in Q1, Cango disposed of 2,000 BTC to pay down debt, and Bitdeer reported zero Bitcoin holdings as of Feb. 20 [2]. Those sales signal a broader reset in how miners view hardware, power and financing. Juliet Ye, head of communications at Cango, says the efficiency gap between legacy and newer rigs is widening, forcing “real decisions around fleet upgrades” and a shift toward long‑term energy contracts rather than chasing cheap tariffs [1][2]. “There is less room in the middle now,” she adds, noting that operators with scale and diversification will manage the upcoming squeeze, while smaller players may struggle.

GoMining CEO Mark Zalan echoes the capital‑first mindset, arguing that new deployments must now meet tougher return thresholds before funding is approved. He describes pure block‑reward mining as a “thinner business than it once was” and predicts stronger operators will adopt models resembling power and data‑center firms, monetizing grid services, curtailment and heat reuse to supplement shrinking subsidies [1][2]. Zalan also believes the market has not fully priced in the 2028 halving, suggesting that Bitcoin’s scarcity will meet a “much stronger ecosystem” by then.

From a mining‑pool perspective, Alejandro de la Torre, co‑founder of DMND, says the core dynamics of mining cycles remain unchanged. He expects dominant mining regions to peak and then cede ground, opening space for mid‑size miners to form new energy partnerships in emerging markets, which could broaden decentralization [1][2].

The combined pressure of higher input costs, tighter energy markets and clearer regulation is nudging miners away from being pure Bitcoin proxies toward infrastructure operators with diversified revenue streams. Investors are already re‑rating firms that lock in high‑performance compute contracts at more than double the revenue multiples of pure‑play miners, according to Ye [2].

If the 2024 cycle rewarded miners that rode Bitcoin’s price strength, the run to 2028 will likely favor those that can manage debt, secure long‑term power and build multi‑purpose facilities. The open question remains: will the industry’s shift toward infrastructure and diversified income be enough to offset the halving‑driven revenue drop and keep smaller operators afloat?
