Exhibit 99.1

BIT Mining LimitedExpands into the Solana Ecosystem

An SOL treasuryof up to $300 million will highlight strategic expansion

AKRON, Ohio, July 10, 2025 – BIT Mining Limited (NYSE: BTCM) (“BIT Mining” or the “Company”), a leading technology-driven cryptocurrency mining company, today announced a strategic shift with its expansion into the Solana ecosystem, marking a critical milestone in the Company’s long-term growth trajectory. This transition positions BIT Mining to capture emerging opportunities across the broader blockchain value chain, while also attracting investors seeking exposure to the Solana ecosystem. By entering the Solana ecosystem, the Company aims to leverage its high-performance infrastructure and dynamic developer community to drive innovation, enhance ecosystem integration, and create sustainable shareholder value.

As part of this strategic realignment, BIT Mining will build a robust SOL treasury as a core pillar of its strategic shift. To support its Solana-focused strategy, the Company plans to raise between $200M and $300M in phases, based on market conditions and capital availability. Proceeds will be used to accumulate SOL tokens, strengthening the Company’s treasury reserves through ongoing capital deployment and incremental acquisitions.

To initiate the treasury, BIT Mining will convert its existing crypto holdings into SOL and adopt a long-term holding strategy. Looking ahead, the Company intends to further capitalize on its market expertise and proprietary technologies by deepening its participation in the Solana ecosystem, including operating validator nodes to support network decentralization and security, while generating stable, on-chain staking rewards.

Xianfeng Yang, CEO of BIT Mining, commented on the news, “We are excited to take this bold step into what we believe is one of the most dynamic and promising ecosystems in the blockchain space. This strategic move reflects our commitment to staying adaptive and responsive in an ever-evolving industry. With our strong execution capabilities and long-term vision, we are confident in our ability to accelerate sustainable growth and deliver lasting value to our shareholders.”
