Speaking at the Blockworks Digital Assets Summit on March 20, 2025, President Donald Trump pledged to make the United States 'The undisputed bitcoin superpower.'
Yet, with mounting operational expenses and sluggish bitcoin prices, implementation is anything but easy.
Bitcoin's hashrate continues to surge to all-time highs, underscoring the network's rapid expansion and the growing demand for computational power. Driving this evolution is a crucial, but frequently overlooked component of the ecosystem: application-specific integrated circuits, the purpose-built machines that power bitcoin mining.
Hashrate isn't just a technical metric, it's a proxy for the health, security, and resilience of the Bitcoin network.
But, the production of ASIC mining hardware has long been dominated by just two players: Bitmain and MicroBT.
Since bitcoin's early days in 2009, when enthusiasts mined the cryptocurrency from personal computers, the mining industry has grown into a global, multi-billion-dollar enterprise.
Over the years, companies like Bitmain and MicroBT have dominated the market, capitalizing on efficient manufacturing and access to chip foundries. However, as demand for computing power expands, especially with the rise of AI, new competitors such as Auradine, Braiins, and Block's Proto team are stepping in.
This period marks a pivotal shift in the ASIC landscape, where innovation and efficiency are key to staying competitive. Particularly, each Bitcoin halving cycle fuels the need for next-generation mining technology.
More companies are entering the bitcoin mining chip market, including Auradine, Braiins, and Block's Proto.
Auradine and Block are based in the U.S., while Braiins operates in the Czech Republic. Together, they represent a new wave, making the bitcoin mining market more competitive.
Auradine, founded in 2022 in Silicon Valley, recently launched its AH3880 miner. Designed for efficiency, stability, and AI integration, it features a closed-loop hydro cooling system that enhances energy use and longevity, positioning it as a strong competitor to existing market leaders. Its reliability and forward-looking design catch the attention of large-scale operators and data centers alike.
Also founded in 2022 is Proto. Supported by Jack Dorsey's Block and partnering with Core Scientific, they take a distinctly open-source approach to Bitcoin mining.
Proto's open ASIC platform supplies developers with chips, systems, and tools to create custom solutions. This effort aims to reduce entry barriers, encourage innovation, and decentralize control in a market long dominated by a handful of major players.
Braiins, long known for its contributions to mining software, is now building its own ASIC hardware.
The company aims to challenge that dynamic with a more decentralized, flexible design architecture.
This next generation of mining hardware companies is also aligned with broader trends in the energy and infrastructure sectors.
Riot Platforms, one of the largest bitcoin mining companies, CEO Jason Les, said at the Bitcoin for America Summit in March 2025,
Les emphasized that miners can act as flexible energy consumers, helping balance grids and accelerate the development of power infrastructure for AI and data centers.
Redefining the future of bitcoin mining isn't just about who builds the fastest machines, it's about creating a competitive ecosystem.

Leveraged Bitcoin Longs on Bitfinex Weakest Since December and It Could Mean Rally Time
Those who have followed financial markets for some time may have heard of contrary indicators. These metrics are often misleading at first glance – some appear positive but tend to signal a market downtrend, while others that seem negative mark price upswings. One such contrary indicator is leveraged bitcoin longs on the crypto exchange Bitfinex. Historically, the number of leveraged longs on the exchange has tended to slide during bull runs and rise during bearish trends. As of writing, the number of BTCUSD longs on Bitfinex had fallen to 47,691, the lowest since December, offering bullish cues for bitcoin, according to data source TradingView. The tally of longs peaked in the first half of April and has been declining since then, characterizing BTC's rapid recovery from around $75K to record highs of over $110K. "When Bitfinex Long Positions rise, the price tends to fall. When Long Positions drop, the price usually goes up," crypto analytics firm Alphractal said on X. Explaining the conundrum, Alphractal said that traders are typically wrong about the market direction. That leads to forced or discretionary liquidations, which drive the price in the opposite direction. "As long as Bitfinex Long Positions keep dropping, Bitcoin will continue to rise," João Wedson, CEO of Alphractal, noted. The chart shows the contrary nature of the BTCUSD longs on Bitfinex. Since 2021, every major BTC rally, including those seen in November-December last year and the latest one from early April lows, has coincided with the slide in BTCUSD longs on the exchange. On the other hand, BTC's bear trends, including the 2022 crash and the decline from $100K to $75K seen early this year, occurred as BTC/USD longs surged.

US, China to Resume Trade Talks With Focus on Rare Earth Exports
(Bloomberg) -- Supply Lines is a daily newsletter that tracks global trade. Sign up here. Next Stop: Rancho Cucamonga! Where Public Transit Systems Are Bouncing Back Around the World ICE Moves to DNA-Test Families Targeted for Deportation with New Contract Trump Said He Fired the National Portrait Gallery Director. She's Still There. US Housing Agency Vulnerable to Fraud After DOGE Cuts, Documents Warn Top trade negotiators from the US and China are set to hold fresh talks in London on Monday, offering a glimmer of hope that the world's two largest economies can defuse tensions over Chinese dominance in rare-earth minerals. Both sides have accused the other of reneging on a deal in Geneva in May where they tried to start dialing back their trade war. Relations have spiraled since President Donald Trump's return to the White House, stoking uncertainty for companies and investors. China said Saturday it approved some applications for rare-earth exports, without specifying which countries or industries were involved — after Trump said Friday that Chinese President Xi Jinping had agreed to restart the flow of minerals and magnets using the materials. 'We want the rare earths, the magnets that are crucial for cell phones and everything else to flow just as they did before the beginning of April and we don't want any technical details slowing that down,' Kevin Hassett, head of the National Economic Council at the White House, said Sunday on CBS's Face the Nation. 'And that's clear to them.' US-China trade tensions escalated this year as a series of duty hikes on each other's goods sent tariffs well above 100% before hitting a pause. While the Geneva deal was meant to pave the way for a broader de-escalation, subsequent talks quickly stalled amid mutual recriminations. The US complained about a decline in shipments of rare-earth magnets essential for American electric vehicles and defense systems, while China bristled at tightened US restrictions on artificial intelligence chips from Huawei Technologies Co., access to other advanced technologies and crackdowns on foreign students in the US. Trump's reprieve on US tariffs for Chinese goods runs out in August, unless he decides to extend it. If deals aren't reached, the White House has said Trump plans to restore tariff rates to the levels he first announced in April, or lower numbers that exceed the current 10% baseline. In London, US Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick and US Trade Representative Jamieson Greer will meet a Chinese delegation led by Vice Premier He Lifeng. Trump offered a positive spin on what has been a rollercoaster relationship since he took office in January, saying on social media that the talks should go 'very well.' While a call between Trump and Xi last week generated some hope on Wall Street for lower duties between the trading partners, investors' optimism was limited. While promising to reshape US trading relationships, the US president has reached only one new trade agreement — with the UK. The Geneva meeting underscored the challenge of deal-making between China and the US. 'There was confusion and misunderstanding or misinterpretation intentionally on both sides, depending on how you look at it, about what was agreed to,' said Josh Lipsky, chair of international economics at the Atlantic Council. 'They left too many things open to interpretation and they all paid the price for it in the intervening weeks.' After the two leaders spoke, the Chinese Foreign Ministry said Trump told Xi that Chinese students are welcome to study in the US. Trump later said it would be his 'honor' to welcome them. For now, Xi appears to be betting that a reset in ties will lead to tangible wins in the weeks and months ahead, including tariff reductions, an easing of export controls and a less-fraught tone. The US and China 'just want to get back to where they were in Switzerland with a few more agreements down on paper to actually understand what is gonna be licensed, what gets permitted, what doesn't,' Lipsky said.

Opinion - What's the matter with Ohio? Trump tariffs are a loser even in Red states.
Donald Trump largely got a second chance at the presidency due to a deep dissatisfaction with the economy. It turns out his tariff policy has not eased fears and in fact may be fueling deeper anxieties among voters. It is one of the few issues where a significant number of Republican voters are willing to break with the president. Notably, independent voters are also spooked by tariff uncertainty. While public opinion polling in the aggregate has illustrated these trends, few polls have probed how Red State voters are reacting to Trump's tariff policies. Once a prized bellwether state, Ohio has now voted solidly Republican in the last three elections, including a double-digit margin of victory for Trump in 2024. Yet, our poll of Buckeye voters finds Trump is currently underwater and the tariffs are a major reason why. A majority of Ohio voters (51 percent) believe the Trump tariff policies will personally hurt them and just 1 in 4 think his tariff policies will benefit them. About half think the tariffs will hurt the United States (49 percent), while 38 percent think the country will benefit from them. This is somewhat vexing as Trump had long indicated he would engage in an aggressive tariff policy in his second term. Perhaps the uneven rollout and increased media attention to the potential effects of tariffs on the American consumer could be driving the discontent. Although Trump enjoys almost universal support among Republicans in our poll on most issues, there is some melt when it comes to the tariffs. Just 47 percent of Republicans think the tariffs will personally help them, and less than 1 in 5 think the tariffs will personally hurt them. Independents also provide some caution, as a majority (53 percent) think they will personally be hurt by Trump's tariff policies. The poll finds some rare bipartisan agreement in who respondents think will benefit most from the tariff policies. Respondents overwhelmingly think the tariffs will benefit the wealthy (66 percent) and large corporations (60 percent). Majorities of both Democrats (75 percent) and Republicans (56 percent) believe the wealthy will benefit from the tariff policies. Seventy-two percent of independents also believe the wealthy will benefit. When it comes to large corporations, however, it is Republicans who are most likely to agree that these entities would likely benefit from the Trump tariff policies, with 67 percent in agreement, compared to 55 percent of Democrats and 51 percent of Independents. Large majorities of all respondents believe that small businesses (59 percent), the middle class (58 percent), the working class (58 percent), labor unions (58 percent) and the United States automobile industry (54 percent) do not stand to benefit from the tariffs. Although Trump has claimed that his tariff policies would benefit these groups, thus far, most people appear to be skeptical. This is a message Democrats will likely amplify leading up to next year's midterm elections. As might be expected, the largest amount of agreement among all respondents is that foreign governments would not benefit from the tariffs (75 percent). Overall, we find Trump's approval in Ohio is underwater with 47 percent approving and 48 percent disapproving of his job in office. Keep in mind that this poll is of voters who indicated they supported Trump by a 10-point margin, largely reflecting the actual outcome of the 2024 election in the state. Moreover, this is a 7-point slide in favorability from when we polled Ohio voters in February of this year. Nationally, Trump's approval is at minus 4, with 46 percent approval and 50 percent disapproval. The frenzied pace of the first few months of the second Trump presidency has created some unease among many voters as well. Not surprisingly, nearly 9 in 10 Democrats feel more anxious (86 percent). More broadly, majorities of non-whites (59 percent), those 18-44 (53 percent) and women (50 percent), personally feel more anxious with Trump as president. While 24 percent of independents are less anxious with Trump as president, 43 percent are more anxious with him as president. Notably, Trump has changed course on the implementation of his tariffs on several occasions already, likely fueling more uncertainty among voters. Citizens across the country and in red states in particular have conveyed a strong distrust in government and an impulse for change. The advantages Republicans have in the House and Senate may be in jeopardy, given that the president's party has an average midterm loss of 28 seats in the House and 4 seats in the Senate from 1934-2018. In 2022, Republicans gained just 8 seats in the House and lost one seat in the Senate. If public opinion continues in this direction, especially in red states, some Republicans will be faced with difficult choices on how closely they align themselves with Trump and his tariff agenda.
