The crypto mining rig makers

  • Canaan (finally) reported its fourth quarter and full-year 2020 earnings. The company’s revenues continued to decline though it narrowed its losses. The company’s outlook was more positive: It said that it has laid a “solid foundation” for growth in Q1 2021. (TechNode)
  • Bitmain sued relative newcomer MicroBT for intellectual property theft for the second time. MicroBT’s founder was a chip engineer at Bitmain. A previous lawsuit over similar claims was dismissed by a Beijing IP court in 2018. (The Block)

The bell tolls for Filecoin
