After the 2024 halving, Bitcoin mining entered its fifth epoch and block rewards were reduced from 6.25 BTC to 3.125 BTC. This forced miners to rethink their operations, optimize efficiency, cut energy costs and upgrade hardware to remain profitable. Cointelegraph Research, with insights from industry experts at Uminers, examines this transformation in its latest report. The analysis covers ASIC efficiency improvements, corporate performance, geographical expansion and new revenue models. As miners adapt, Bitcoin moves into a new era where institutional momentum and sovereign adoption could redefine its role in the global financial system.
The mining industry’s response to rising hashrate and shrinking margins
Despite the adverse financial impact of the halving, Bitcoin’s network hashrate has continued to climb. As of May 1, 2025, the total computational power of the network reached 831 EH/s. Earlier in the month, hashrate peaked at 921 EH/s, marking a 77% increase from the 2024 low of 519 EH/s. This rapid recovery underscores the industry’s relentless drive for efficiency as larger mining firms reinvest in fleet upgrades and energy optimization to maintain profitability.
The mining arms race has always revolved around power efficiency. With energy costs rising, the latest ASIC models from Bitmain, MicroBT and Canaan are further optimizing the energy required per hash. Bitmain’s Antminer S21+ delivers 216 TH/s at 16.5 J/TH, while MicroBT’s WhatsMiner M66S+ pushes immersion-cooled performance to 17 J/TH. Meanwhile, semiconductor giants TSMC and Samsung are driving the next wave of innovation, with 3-nm chips already in use and 2-nm technology on the horizon.
Post-halving profitability: The global shift toward low-cost energy
Bitcoin mining profitability has tightened significantly post-halving. Hashprice, the daily revenue per terahash per second, dropped from $0.12 in April 2024 to about $0.049 by April 2025. At the same time, network difficulty has surged to an all-time high of 123T, making it harder for miners to generate returns. To stay competitive, operations must extract maximum value from every watt of power consumed. This shift has intensified the search for cheap, reliable power, driving mining expansion into regions where energy costs remain low.
Electricity pricing now dictates mining profitability. In Oman, licensed miners benefit from government-backed subsidies, securing electricity at $0.05–$0.07 per kWh, while in the UAE, semi-governmental projects operate at even lower rates of $0.035–$0.045 per kWh. These incentives have turned the region into a prime destination for institutional-scale mining. Meanwhile, in the US, where industrial power costs often exceed $0.1 per kWh, miners face shrinking margins, forcing a migration toward more cost-efficient locations. Africa, the Middle East and Central Asia have emerged as key battlegrounds in this race, offering the energy arbitrage opportunities miners need to survive.
What’s next for Bitcoin mining?
The 2024 halving has reinforced a hard truth: Efficiency is no longer optional; it’s a necessity. The industry is shifting toward leaner, more optimized operations, where only the most power-efficient miners can thrive. The rise of AI computing, global regulatory shifts and ongoing hardware advancements will continue to shape the sector over the next 12–18 months.

Coinbase chief legal officer Paul Grewal addressed some of the concerns raised by US lawmakers and industry leaders around President Donald Trump’s crypto ventures, and how they may affect related legislation.
Speaking at the Consensus conference in Toronto on May 15, Grewal said there had been “hiccups” in Congress since the Senate Banking Committee voted to advance the Guiding and Establishing National Innovation for US Stablecoins, or GENIUS Act, in March. Though Grewal said there were disputes over “substantial issues that need to be addressed” in the bill, he hinted that Trump’s involvement in the industry was a “complicating factor.”
“The discussion around the president’s support for a certain memecoin or two and other efforts does add a certain level of challenge to the effort to get Democrats and Republicans aligned on the right way to regulate the [spot market], but I have confidence that the Senate and the House are going to sort all that out,” said Grewal.

Democrats including Senator Elizabeth Warren explicitly called out the Trump family’s crypto venture, World Liberty Financial, and its USD1 stablecoin in opposing the GENIUS Act. However, some of the bill’s supporters, like Senator Kirsten Gillibrand, who proposed an earlier version of the legislation, said they would remove language specifically targeting the president’s crypto ventures.
Whatever the terms for modifications to the bill may be, many lawmakers still expect the Senate to take up another vote in a matter of days. Punchbowl reported on May 15 that Democrats “won major victories” after receiving assurances that some of their concerns around consumer protection, Anti-Money Laundering, and national security safeguards would be addressed.
First stablecoins, then a market structure bill?
The House of Representatives is also considering draft legislation for a digital asset market structure bill, a different iteration of the FIT21 bill that passed the chamber in May 2024. Democratic representatives have similarly pushed back on the legislation, citing “Trump’s crypto corruption.”
“I think we’re gonna learn a lot from the progress we see just in the next few days on stablecoins on the appetite to really tackle all these problems on any schedule that resembles the one that was laid out not long ago by the White House and certain leaders in Congress,” said Grewal.
Stablecoin regulation is “the next catalyst” for the crypto industry and could lead to unprecedented “appetite from institutional investors,” according to Ash Pampati, head of ecosystem at the Aptos Foundation.
In an interview with Cointelegraph at Consensus 2025 in Toronto, Pampati said that “the whole world outside of the United States […] has already jumped onto this [stablecoins],” adding that “the US is […] at the doorstep.”
“I really think about new use cases that can emerge because of the borderless nature of stablecoins, because of the efficiency of the dollar onchain,” he said. “If you’re trying to send money to your friend in Nigeria, why do you have to go through a bunch of hoops?”
Stablecoins are often used to transfer money across borders, as they are easier and cheaper to transfer than traditional finance methods such as wire transfers. They are also used to hedge against fiat currency, which, in emerging markets, can devalue significantly in a short period of time.
According to a new survey from Fireblocks, Latin America leads all regions in real-world use of stablecoins, with 71% of respondents saying they use the technology for cross-border payments. Half of respondents in the region, which encompasses a number of developing countries, say they expect stablecoins to offer lower transaction costs than traditional finance rails.
“I think you will see an amazing appetite from institutional investors […] we can really think, rethink the fintech space across B2B, B2C with fully onchain rails,” Pampati said.
86% of firms ready for stablecoins
According to Fireblocks’ survey, 86% of respondents say that their company shows “infrastructure readiness.” In other words, their companies are ready to adopt stablecoin. In addition, 75% of respondents say they see clear customer demand for stablecoins.

However, regulation still holds a large role in determining adoption. The survey shows that confidence in stablecoins is rising, not only because of the technology but also because regulatory barriers have fallen.
A 21-year-old man has been charged with three counts of arson with intent to endanger life after fires at two properties and a car linked to Prime Minister Sir Keir Starmer.
Roman Lavrynovych, 21, a Ukrainian national from Sydenham, southeast London, is due to appear at Westminster Magistrates’ Court on Friday, the Metropolitan Police said.
The force said officers from the Met’s Counter Terrorism Command led the investigation because of the connections to the prime minister.

There was another blaze at the front door of a house converted into flats in Islington, also linked to the prime minister, on Sunday.
One person was taken to safety via an internal staircase by crews wearing breathing apparatus, London Fire Brigade said.
The head of the Crown Prosecution Service counter terrorism division, Bethan David, said: “These charges relate to two fires at residential addresses in Islington on Sunday May 11 and in Kentish Town on Monday May 12, as well as a car fire in Kentish Town on Thursday May 8.
“The Crown Prosecution Service reminds all concerned that criminal proceedings against this defendant are now active and that he has the right to a fair trial.”
