“Our new origin has begun,” said Jinghai Jiang, CEO,COO and Chairman of the Board of Bit Origin. “From our experience in mining, we understand the tradeoffs that define proof-of-work systems. We see Dogecoin’s utility potential for micropayments nearing an inflection point, driven by renewed developer activity and broader institutional interest in tokenization. While we embrace its cultural origins, which have helped drive liquidity and global familiarity, we believe current market conditions align with Dogecoin’s evolution toward decentralized finance.”

¹DOGE-Per-Share calculated by dividing the Company’s current Dogecoin holdings by the total number of Class A and Class B ordinary shares outstanding as of April 18, 2025, as most recently reported.
