MercurityFintech Holding Inc. Announces Strategic Engagement with BitGo for Institutional-Grade Custody Services

New York, March 12, 2025 — Mercurity Fintech Holding Inc.

The engagement with BitGo is expected to deliver several strategic benefits to MFH, including enhancing digital asset security, strengthening regulatory compliance, boosting credibility with investors, demonstrating a proactive approach to risk management and investor confidence.

“Partnering with BitGo represents a pivotal step in our long-term strategy to provide our investors and clients with best-in-class security and regulatory assurance,” said Shi Qiu, CEO of Mercurity Fintech Holding Inc. “ As we continue to innovate at the intersection of traditional finance and blockchain, this collaboration reinforces confidence that assets under our management are safeguarded by one of the most trusted custodians in the industry.
