The Bitcoin mining industry finds itself entangled in the US-led trade war, facing hefty tariff liabilities from US Customs and Border Protection (CBP). Public miners like CleanSpark and IREN are bracing for potential costs exceeding $185 million and $100 million respectively. These companies received invoices alleging Chinese equipment originations under the revised tariffs, impacting revenues already strained by declining transaction fees. Meanwhile, the broader blockchain sector is forging partnerships with Wall Street institutions as institutional investors increasingly embrace crypto assets. This week’s Crypto Biz newsletter delves into these developments, highlighting The Miner Mag’s latest findings, Polkadot’s new capital markets division, SharpLink’s significant ETH purchase and reports of China potentially greenlighting yuan-backed stablecoins.
