SINGAPORE, June 4, 2025 (GLOBE NEWSWIRE) — BitFuFu Inc. (“BitFuFu” or the “Company”) (NASDAQ: FUFU), a world-leading Bitcoin miner and mining services innovator, today announced its unaudited production and mining operation updates for May 2025.
“To meet the continued strong demand for cloud mining services, in May we further expanded our hashrate and power capacity to record levels of 34.1 EH/s and 651 MW, respectively,” said Leo Lu, Chairman and CEO of BitFuFu.
“In May 2025 alone, BitFuFu mined 400 BTC, including 357 BTC mined by our cloud-mining customers. The significant increase in Bitcoin production in May, up 91.4% month-over-month, directly reflects a full month’s contribution from the additional hashrate purchased in late April. Similarly, the new hashrate acquired at the end of May is expected to position the Company for another strong increase in Bitcoin production in June, as Bitcoin productions benefit from this expanded capacity throughout the entire month.”
Lu continued, “Consistent with our disciplined treasury management strategy, after suspending Bitcoin sales for almost four months, we opportunistically sold 178 BTC at an average price of $104,000 during the recent all-time high in May. These strategic sales enabled us to capitalize on favorable market conditions, efficiently cover operational expenses, and strengthen our liquidity. Our long-term conviction in Bitcoin is unchanged, and we will continue to hold a substantial balance while managing the business responsibly.”
