Less than two months after the April 2024 Bitcoin halving slashed block rewards from 6.25 to 3.125 BTC, the network’s seven-day average hashrate reaches an all-time high, defying widespread predictions of a mining exodus. On the same day, the mining industry witnesses a dramatic corporate maneuver as Riot Platforms launches an unsolicited $950 million takeover bid for Bitfarms, signaling that the sector’s consolidation phase has arrived in earnest.
TL;DR
- Bitcoin’s seven-day average hashrate reaches a new all-time high on May 29, 2024, just weeks after the halving
- Riot Platforms makes an unsolicited $950 million acquisition offer for Bitfarms Ltd.
- Bitfarms responds by adopting a shareholder rights plan to block the hostile takeover
- Despite the halving cutting rewards in half, mining competition intensifies as efficient operators expand
- Bitcoin trades near $67,578, keeping mining economics viable for well-capitalized operators
Hashrate Defies Post-Halving Expectations
When Bitcoin underwent its fourth halving on April 19, 2024, reducing miner rewards from 6.25 BTC to 3.125 BTC per block, many analysts predicted a significant drop in network hashrate as unprofitable miners would be forced to shut down their operations. Instead, the opposite happens. By May 29, Bitcoin’s seven-day average hashrate climbs to a new record high, demonstrating the resilience and adaptability of the mining sector.
This counterintuitive outcome is driven by several factors. First, Bitcoin’s price has remained elevated near $67,578, meaning that even the reduced 3.125 BTC reward translates to roughly $211,180 per block — still a substantial incentive for miners. Second, the deployment of next-generation mining hardware, including machines achieving 200 TH/s with improved energy efficiency, allows operators to maintain profitability despite the reward reduction. Third, large-scale miners have been aggressively expanding their capacity in the months leading up to the halving, and these investments continue to come online.
Riot Platforms vs. Bitfarms: A Mining Industry Power Struggle
The corporate drama unfolding between Riot Platforms and Bitfarms adds a fascinating dimension to the post-halving mining landscape. On May 28, Riot Platforms announces an unsolicited proposal to acquire all outstanding shares of Bitfarms Ltd. at a valuation of approximately $950 million, representing a significant premium over Bitfarms’ trading price at the time.
Riot, one of North America’s largest publicly traded Bitcoin mining companies, sees the acquisition as a strategic opportunity to expand its operational footprint and achieve economies of scale in an increasingly competitive environment. The combined entity would control a substantial portion of the global Bitcoin mining hashrate, with operations spanning multiple countries and energy markets.
Bitfarms, which operates mining facilities across Canada, the United States, Paraguay, and Argentina, does not welcome the approach. On May 29, the company confirms receipt of Riot’s proposal and promptly announces the adoption of a shareholder rights plan — commonly known as a “poison pill” defense — designed to prevent Riot from accumulating a controlling stake without board approval.
The Consolidation Imperative
The Riot-Bitfarms confrontation reflects a broader trend sweeping the Bitcoin mining industry in the wake of the halving. With rewards cut in half, only the most efficient and well-capitalized operators can maintain healthy profit margins. This creates powerful incentives for mergers and acquisitions, as larger companies seek to absorb smaller competitors and achieve the scale needed to remain competitive.
Bitfarms reports impressive growth metrics in its recent filings, highlighting a 223% hashrate increase and 40% efficiency improvement. The company holds approximately 48.18 BTC on its balance sheet, worth roughly $3.25 million at current prices, along with cash reserves. These fundamentals make it an attractive acquisition target despite the defensive posture adopted by its board.
Energy Efficiency Becomes the Deciding Factor
As hashrate reaches new highs, the importance of energy efficiency in mining operations cannot be overstated. Post-halving, the cost to mine one Bitcoin effectively doubles in raw energy terms, placing enormous pressure on operators to secure the cheapest possible electricity. Mining companies are increasingly relocating operations to regions with abundant, low-cost renewable energy, or negotiating long-term power purchase agreements that provide cost certainty.
The push for efficiency is also driving investment in immersion cooling technology, which allows mining hardware to operate at higher speeds while consuming less power for temperature management. Companies that have invested in these technologies ahead of the halving now enjoy a significant competitive advantage over those still relying on traditional air-cooled facilities.
Why This Matters
The simultaneous occurrence of record hashrate and a major mining industry acquisition battle tells us something profound about Bitcoin’s maturity as an asset class and an industry. The network’s security — directly tied to hashrate — continues to strengthen even as the economic model for miners undergoes its most dramatic shift since 2020. The Riot-Bitfarms situation foreshadows a wave of consolidation that will likely reshape the mining sector over the coming year, concentrating hashrate among fewer, larger, and more efficient operators. For Bitcoin investors, this means the network’s security infrastructure is becoming more robust and professional, managed by publicly traded companies with board oversight and fiduciary responsibilities. For the mining industry itself, the halving has accelerated a Darwinian process where only the most operationally excellent survive, setting the stage for a more mature and sustainable mining ecosystem.

hashrate at all time highs 6 weeks after the halving. everyone who predicted a mining exodus was dead wrong
hostile takeover was always the endgame for post-halving mining. the math is simple, bigger fleets means lower per-unit energy costs. bitfarms shareholder rights plan is just a speed bump
bitfarms adopted a poison pill to stop riot but honestly that just delays the inevitable. post-halving survival requires scale and their power contracts cant compete
Riot bidding $950M for Bitfarms while BTC is at $67,578 shows how confident the big miners are. Hostile takeover season is here.
riot borrowing $950M worth of stock for a hostile bid tells you they see post-halving consolidation as the play. smaller miners are going to get eaten
200 TH/s machines with better efficiency are the reason hashrate keeps climbing. the old rigs die, new ones more than replace them
hashrate hitting ATH after rewards got cut in half is the most bullish signal for BTC security imaginable. efficient miners just keep winning
200 TH/s machines replacing older rigs is just the hardware cycle. what matters is that breakeven cost is still below $67K for efficient miners post halving
breakeven depends on your energy contract though. miners with fixed-rate power deals from 2022 are printing, everyone else is sweating
