Sustainable Bitcoin Mining and AI: Industry Shifts, Profits, and Global Expansion

Green Mining DAO: Sustainable and Profitable Bitcoin Mining in Paraguay

According to MoneyToday, the Swiss startup Green Mining DAO has been pursuing a business model for three years that aims to combine profitability and sustainability in Bitcoin mining. The company operates three mining facilities in Paraguay, a country that generates 100% of its electricity from renewable hydropower, mainly from the Itaipú, Yacyretá, and Acaray projects. Paraguay exports about 70% of its electricity to neighboring countries, and Green Mining DAO sources its power from ANDE, which supplies only renewable hydropower.

The startup pays electricity prices between $0.047 and $0.057 per kWh, enabling efficient and profitable mining. The latest facility, Green Mine #003 (GM3), located in Villarrica, has been operational since September 2024 and is being expanded from 2 MW to 6 MW. Green Mining DAO also utilizes the waste heat from mining to operate dehydrators for drying mangoes, which helps local families increase their income by up to 50% and saves up to 2.5 tons of CO2 per megawatt.

Investors in Green Mining DAO do not invest directly in Bitcoin but become co-owners of sustainable mining facilities through tokenized shares. The average production cost is 31% below the Bitcoin market price, and about 10% of revenues are reinvested in new machines and infrastructure. The majority of profits go to investors, who receive quarterly Bitcoin dividends. In Q1 2025, a total of 0.57 Bitcoin was distributed as dividends, and a long-term dividend yield of up to 20% is targeted at full capacity.

The company plans to expand to a new continent each year, focusing on regions with access to renewable energy and low electricity prices. Facilities are built in mobile containers, allowing for quick relocation if regulatory or political conditions change.

Bitcoin Miners Under Pressure: Low Fees and Market Shifts

CoinDesk reports that while the Bitcoin price remains near record highs, transaction fees have dropped to a decade low. Data from Glassnode shows that median daily fees have fallen by over 80% since April 2024, with up to 15% of daily blocks now settled at just 1 satoshi per vByte. Nearly half of recent blocks are not full, indicating weak demand for blockspace and a quiet mempool.

This is a stark contrast to previous bull cycles, where price rallies led to congestion and fee spikes. The shift is attributed to spot ETFs and custodians now holding over 1.3 million BTC, with these coins rarely moving on-chain. Retail activity has migrated to Solana, where memecoins and NFTs benefit from lower costs and faster execution.

For miners, this environment is challenging. With block rewards halved to 3.125 BTC and fees making up less than 1% of block revenue in July, profitability is under pressure. Publicly traded miners are diversifying into AI and HPC hosting to offset declining mining returns. The CoinShares Bitcoin Mining ETF is up nearly 22% year-over-year, while BTC itself is down over 3%, reflecting investor preference for diversified business models.
