2019 hasnt been great for Bitmain, Wu said in Tuedays internal meeting.
Even with bitcoins price rebound, Wu said the company didnt fully seize the moment.
Our mining equipments market share is declining, he said. Our mining pools dominance is also declining.
Indeed, Bitmains major rival miner makers including Canaan, WhatsMiner and InnoSilicon have all been able to increase sales following the market boom this year.
Meanwhile, BTC.com and Antpool, Bitmains flagship mining pools, lost their long-time dominant positions to Poolin founded by former BTC.com creators and F2Pool. Poolin and F2pool are currently the top two mining pools in the world, based on the real-time hash rate distribution.
Wu wanted to cut costs and lay people off, Zhan didn't.
