The 50 Most Interesting Companies In Bitcoin's History: 18/50

F2Pool

Founded by Chun Wang, Mao Shihang 2013 · Mining Pools · Active
The Idea: China's first Bitcoin mining pool. Wang had been GPU mining since 2011 but realized ASICs made solo mining obsolete. He coded the backend; Discus Fish (who had built a 50,000-member Chinese mining community on QQ) handled operations. Launched May 5, 2013 from Wenzhou.
Early Traction: Grew explosively as China became the epicenter of Bitcoin mining. At peak, commanded roughly one-third of Bitcoin's entire network hashrate.
Peak Stats: One-third of global Bitcoin hashrate at peak. Mined over 1.3 million BTC total. The largest mining pool in the world today.
Status Today: Active. Still one of the top mining pools globally. Wang became notable for his colorful personality - he later went to space on a commercial flight.
Why It Matters:

F2Pool represented the rise of China as the dominant force in bitcoin mining, and the company remains one of the largest bitcoin mining pools today despite China's bitcoin mining ban.
