  • Post-halving competition squeezes miners as August output declines, with smaller firms exiting while majors like MARA dominate.
  • Marathon Digital mined 705 BTC and grew holdings to 52,477, while BitFuFu saw a sharp 12.6% output drop, signaling uneven resilience.
  • Despite weaker production, most listed miners increased BTC holdings, favoring accumulation over sales to weather rising costs.

The Bitcoin mining industry’s competition intensifies after a recent halving, with leading firms like Marathon Digital showcasing strong output and holdings. 

Meanwhile, other players face significant challenges, reflecting a dynamic and evolving market landscape.

Competition Becomes Fiercer

The Bitcoin mining industry is entering a fiercely competitive phase following the 2024 halving, because operating costs continue to rise. This has forced many smaller miners to exit the market, leaving the playing field to large publicly listed mining firms. As a result, the concentration of mining in large companies also causes the market to face the problem of centralization.

According to CompaniesMarketCap, major players such as Marathon Digital (MARA), Riot Platforms, CleanSpark, and Cango maintain multi-billion-dollar market capitalizations and continue serving as pillars of the Bitcoin ecosystem. Mining companies rebounded in July when the network hashrate nearly reached an all-time high despite increasing difficulty and competition.

But what about August?

MARA Remains Steady

Public companies’ overall Bitcoin mining output in August was not particularly optimistic compared to July, though the growth rates varied significantly.

Typically, notable shifts came from smaller miners like BitFuFu and Cipher. BitFuFu’s mining output fell sharply to 408 BTC, down 12.63% from July’s 467 BTC, even as its holdings rose slightly to 1,899 BTC. Cipher, by contrast, recorded strong growth, mining 241 BTC compared with 214 BTC in July, a 12.62% increase. In addition, its holdings also expanded significantly to 1,414 BTC, up 16% month-over-month.

Company BTC Mined (July) BTC Mined (Aug) Change (BTC, %) BTC Holdings (End Aug)
Marathon (MARA) 703 705 +2 (0.28%) 52477
Riot Platforms 484 477 -7 (-1.45%) 19309
CleanSpark 671 657 -14 (-2.09%) 12827
Cango 650.5 663.7 +13.2 (+2.03%) 5193
BitFuFu 467 408 -59 (-12.63%) 1899
Cipher 214 241 +27 (+12.62%) 1414

On the contrary, larger miners showed more moderate changes. For instance, Cango mined 663.7 BTC, up 2.03% from July, while CleanSpark produced 657 BTC, down 2.09%. Meanwhile, Riot Platforms slipped 1.45% to 477 BTC, though its holdings climbed to 19,309 BTC.

Above all, Marathon Digital remained steady, with output rising 0.28% to 705 BTC, and it reinforced its position as the industry’s largest holder with 52,477 BTC. The company reinforced its lead as the largest holder, ending the month with 52,477 BTC, an increase of 1,838 BTC.
