Bitcoin mining pool and crypto financial platform EMCD announced on July 27 the launch of its "Miner Support Program", which will provide up to $30 million in support to eligible miners, including financing, fee waivers, and preferential offers for hardware and infrastructure partnerships. The launch comes as the Bitcoin mining industry faces severe profitability pressure following the Bitcoin halving. According to CoinShares' Q1 2026 data, Bitcoin's hash price has dropped to approximately $28 per PH per day, a 50% decline from its October 2025 peak and the lowest level since the halving. Data from Hashrate Index shows that around 252 EH/s of computing power has exited the market due to declining profitability, with a large number of outdated mining rigs forced to shut down due to excessive operating costs. Meanwhile, three consecutive negative mining difficulty adjustments — the first such occurrence since July 2022 — signal the industry is undergoing a massive shakeout. EMCD stated that the support program will provide solutions tailored to the actual operational needs of mining companies, including offering collateralized liquidity support at an annual rate of 3.9% to miners facing financial pressure to help cover their operating costs; it will also launch a 60-day waiver of mining pool fees to reduce mining expenses. In addition, EMCD will offer discounts on Vnish firmware to miners using outdated or inefficient mining rigs, and provide equipment procurement and data center service support for miners looking to expand or migrate their computing power via its partner network. Founded in 2017, EMCD currently operates a Bitcoin mining pool covering over 120 markets, manages more than 30 EH/s of computing power, and ranks among the top 10 Bitcoin mining pools globally.
