BTCT Announces Completion of $1 MillionEthereum Strategic Reserve

 

SINGAPORE, July 11, 2025 /PR Newswire/ – BTC Digital Ltd. (“BTCT”or the “Company”) (NASDAQ: BTCT), a leading blockchain technology company, today announced that it has established astrategic reserve of $1 million in Ethereum (ETH). This milestone marks the first phase of BTCT’s broader initiative to deepenits exposure to Ethereum’s on-chain financial infrastructure and to position the Company for long-term growth in the emerging digital-assetera.

 

“As the stablecoin market continues its explosive growth, Ethereumhas emerged as the foundation of on-chain USD settlement and value transfer,” said Mr. Siguang Peng, CEO of BTCT. “Bysecuring an initial $1 million ETH reserve today—and with plans to scale that position—we are proactively positioningourselves for decentralized finance, stablecoin issuance, and asset tokenization. This strategic move strengthens our technological edge,enhances market confidence, and optimizes capital deployment.”

 

Key Drivers of BTCT’s Ethereum Reserve Strategy:

 

·Dominant Stablecoin Infrastructure: Over half of all major stablecoins—including USDT and USDC—operate on Ethereum,making it the centerpiece of decentralized USD issuance and settlement.
·High-Volume On-Chain Transactions: Stablecoin activity has pushed Ethereum’s on-chain transaction volume to levels approachingtraditional financial rails, underscoring its growing importance in global payments and liquidity networks.
·Collateral and Security Dynamics: As decentralized finance and real-world asset tokenization expand, increased ETH stakingand collateralization will further reduce circulating supply, reinforcing network security and value.
·Institutional Adoption: A number of mining and blockchain firms have already begun integrating ETH into their reserve portfolios,leveraging smart contracts for yield-generation, collateral, and cross-chain financial products.
·Regulatory and Technical Tailwinds: U.S. regulatory clarity, the forthcoming Pectra upgrade, and mature Layer-2 scaling solutionswill significantly boost Ethereum’s throughput, cost-efficiency, and compliance readiness.

LookingAhead


Building on its origins in large-scale crypto mining, BTCT is undergoing a strategic evolution from “hash-rate provider”to “on-chain financial infrastructure participant.” The Company intends to continuously augment its ETH holdings in alignmentwith market developments and network upgrades. BTCT believes that Ethereum, akin to “digital gold,” will remain indispensable—notonly as a stablecoin settlement hub but also as a catalyst for decentralized payments, asset tokenization, and the next wave of globalfinancial interoperability.
