Tether is deepening its commitment to the Bitcoin ecosystem through a dual strategy that bridges infrastructure development and emerging market adoption. The company announced plans to release its modular Bitcoin mining operating system, MOS, as open-source software by the fourth quarter of 2025. Tether CEO Paolo Ardoino says the software is designed to help new entrants bypass costly vendor solutions by offering a scalable and peer-to-peer architecture that supports existing mining infrastructure. In a parallel development, Tether’s USDT stablecoin has appeared as a pricing benchmark in a Bolivian airport store, signaling increased informal use of digital dollars amid the country’s ongoing economic downturn. Tether’s Bold Bitcoin Play: Mining Software Goes Open Source to Spark Decentralization Boom Tether, the powerhouse behind the world’s most widely used stablecoin USDT, is preparing to take a major step into Bitcoin infrastructure with an ambitious open-source initiative. In a move that could democratize Bitcoin mining and challenge the dominance of incumbent players, Tether CEO Paolo Ardoino announced on Monday that the company will open-source its proprietary Bitcoin Mining Operating System (MOS) by the fourth quarter of 2025. The announcement was made via Ardoino’s official X account, where he emphasized that the initiative would pave the way for a ”horde” of new mining companies to join the Bitcoin ecosystem without being shackled by costly and proprietary third-party software systems. The MOS platform is designed as a scalable, modular system that uses a peer-to-peer Internet of Things (IoT) architecture. Tether says it will be compatible with current mining infrastructure, including mining containers and various power delivery modules. This makes the MOS accessible not just to future projects, but to existing operations that want to cut costs and gain flexibility. Strengthening Bitcoin's Decentralization The move is the latest in Tether’s growing list of initiatives aimed at fostering decentralization within the Bitcoin ecosystem. In April 2025, Tether partnered with the Ocean mining pool — a protocol founded by Bitcoin core developer Luke Dashjr — to decentralize block production and ensure smaller miners could remain competitive in the wake of growing industrial consolidation. The partnership saw Tether commit both its current and future hashrate to Ocean, giving weight to its message that decentralization is essential to Bitcoin’s long-term viability. Ardoino’s consistent emphasis on modularity and accessibility signals a strong strategic intent: break down the walls that separate institutional miners from upstarts and hobbyists, and reinforce the core ethos of Bitcoin — trustless, permissionless participation. Tether’s open-source announcement comes at a time of rapid transformation in the Bitcoin mining industry. The recent halving event has significantly reduced block rewards, forcing miners to rethink their strategies in order to remain profitable. Large mining companies still hold key advantages, including access to cheaper energy, bulk hardware purchases, and favorable financing. Yet even these giants are hedging their bets by diversifying operations into new sectors. Hive Digital, once a pure-play crypto mining firm, has seen better margins from artificial intelligence workloads than from mining Bitcoin. According to executive chairman Frank Holmes, institutional interest in Hive’s AI division now dwarfs interest in its crypto operations. Still, not all miners are diversifying away from Bitcoin. Canadian firm Cango has gone in the opposite direction. After selling off its legacy business units, the company doubled down on BTC mining and has already mined over $100 million worth of Bitcoin in just two months. A Gateway for Global Participation Tether’s MOS rollout could be particularly impactful for miners in emerging markets, where access to proprietary mining software is limited and cost-prohibitive. Open-source tools could help bootstrap local mining operations in Latin America, Africa, and Southeast Asia — regions where the appetite for Bitcoin is strong but infrastructure is lacking. By lowering the technical and financial barriers to entry, Tether’s new software initiative could empower a new generation of miners, further decentralize the Bitcoin network, and ignite innovation across the mining stack — from hardware optimization to energy efficiency. While the project is slated for Q4 2025, Tether has not yet shared the specific licensing model or development roadmap for the MOS release. Questions also remain about governance, community contributions, and long-term support for the project. If successful, this open-source experiment could help balance the scales between large-scale miners and decentralized participants, injecting new vitality into the heart of Bitcoin’s decentralized promise. Tether Stablecoin Spotted in Bolivian Airport Store Amid Economic Crisis Meanwhile, in a vivid sign of the changing global monetary landscape, Tether’s USDT stablecoin appears to be gaining an unlikely foothold in South America — particularly in Bolivia, where the national currency is rapidly losing credibility. Over the weekend, Ardoino shared a series of photos showing items priced directly in USDT at a Bolivian airport store, highlighting the growing unofficial use of crypto as a medium of exchange in a country reeling from economic instability. A New Normal in Airport Retail The photos, posted to Ardoino’s official X account, were taken at Duty Fly, a duty-free shop inside a Bolivian airport. The images show various consumer goods, including sunglasses and candy, with price tags denominated in Tether’s USDT — a US dollar-pegged stablecoin. Most notably, one image displayed a formal notice to customers. The sign clarified that customers could still pay in either Bolivianos (the local fiat currency) or US dollars, but the pricing benchmark was set in Tether. According to the shop, USDT’s value was being used to establish a functional exchange rate between the local currency and the dollar — effectively turning USDT into a proxy for currency conversion amid a rapidly eroding official rate. While neither Tether nor Duty Fly responded to inquiries from media, the post immediately sparked conversation across crypto and economic circles. With one USDT equivalent to one US dollar, many observers saw the moment as both symbolic and practical — a sign that Bolivians are increasingly seeking alternatives to a failing monetary system. This is not the first sign of USDT’s growing presence in Bolivia. Back in October 2024, one of Bolivia’s largest banks, Banco Bisa, began offering custody and transaction services for USDT, allowing its clients to buy, sell, and transfer the stablecoin. The move was widely seen as a significant step in legitimizing crypto’s presence in the country, especially amid the broader Latin American trend of crypto adoption as a hedge against currency instability. More recently, reports have emerged suggesting that Bolivia is considering using cryptocurrencies like USDT to pay for cross-border energy imports — a stark reversal from its historical hardline stance against digital assets. In 2020, the Bolivian government banned all use of cryptocurrencies, but the worsening economic picture appears to have forced a reevaluation of that position. A Nation in Economic Freefall The reasons for crypto’s rise in Bolivia are not hard to understand. Once hailed for its economic stability in the early 2010s, the country is now suffering from one of the most severe macroeconomic crises in Latin America. Bolivia’s usable foreign reserves have plunged from $15 billion in 2014 to just $1.98 billion by December 2024. Alarmingly, less than $50 million of that is in liquid cash, with the rest held in gold — a reflection of how tight the government's access to actual dollars has become. The result has been a thriving black market for US currency, with exchange rates on the street soaring to nearly 10 Bolivianos per dollar, far above the official rate of around 7.

Despite these outlays, the country still struggles with fuel shortages. Inflation has also skyrocketed, with the Consumer Price Index hitting 14.6% in March 2025. Ardoino’s photo of a pack of Oreos priced at between 15 and 22 USDT is a particularly stark image — not just of crypto adoption, but of the collapse of consumer purchasing power. That’s roughly $15–22 for a basic grocery item, a price point that would be inconceivable in most developed economies, even accounting for duty-free inflation. Global Symbolism, Local Realities While Tether remains a controversial player in global finance, often scrutinized for its reserve practices, its growing real-world utility in countries like Bolivia is becoming harder to ignore. As a dollar-pegged digital currency that can be accessed via mobile apps and peer-to-peer exchanges, USDT offers a practical workaround for citizens in countries with unstable banking systems, hyperinflation, or currency shortages. For now, it remains unclear just how widespread USDT adoption is in Bolivia beyond isolated cases like Duty Fly. But if current trends continue, the stablecoin’s visibility could move from retail novelty to monetary necessity.
