Bitcoin Mining 2024: Halving, Challenges & Billion-Dollar Moves
By Kapil Rajyaguru
2024 was no ordinary year for Bitcoin mining. The halving event on April 19—Bitcoin’s fourth—halved block rewards from 6.25 BTC to 3.125 BTC, slashing miners’ revenue streams overnight. While Bitcoin’s price soared from $16,615 in early 2023 to over $100,000 by late 2024, miners faced the stark reality of declining profitability.
Monthly subsidies plummeted from $1.49 billion pre-halving to $882 million post-halving, leaving miners grappling with economic challenges. Yet, remarkably, total mining revenue for 2024 reached $13.3 billion, up from $10.5 billion in 2023, driven by price surges and fleeting on-chain activities.
Bitcoin’s hashrate exploded to an unprecedented 727 EH/s—a 43% year-to-date increase—highlighting fierce competition. With global electricity consumption by Bitcoin mining reaching 0.65%, miners found profitability dwindling. Revenue per terahash plummeted from $0.095 at the year’s start to $0.046, pushing miners toward pooling resources
Publicly traded miners were underwhelmed compared to Bitcoin’s staggering 100% gains, with an average return of just 70%. Core Scientific and TeraWulf defied the odds, skyrocketing by 420% and 243%, respectively. Collectively, public miners produced 42,154 BTC—22.69% of the network’s output—while Marathon Digital emerged as a treasury titan, hoarding 27,562 BTC worth $7.1 billion.
Mergers and acquisitions dominated 2024, making it the second-biggest year for Bitcoin mining deals. Highlights included Northern Data’s $435 million acquisition of Damoon and Bitfarms’ $140 million buyout of Stronghold Digital. These strategic moves aimed to scale operations, streamline supply chains, and combat mounting economic pressures.
Bitcoin Ordinals, BRC-20, and Runes tokens briefly revived miner revenues, contributing 16% of monthly income in April. However, by year’s end, fees dropped to a mere 3%, reigniting debates over miners’ reliance on block subsidies.
Concerns over centralization persist, with over 50% of hash power concentrated between Foundry USA and Antpool. Decentralization protocols like Braiins’ Stratum and Ocean’s DATUM aim to redistribute block-building power, but adoption remains low.
As subsidies dwindle, miners must pivot toward transaction fees for sustainability. With new technologies on the horizon and a maturing Bitcoin ecosystem, the industry braces for another transformative year.
