The Ethereum 2.0, or Serenity (called affectionately) update is one of the most awaited ones in crypto history. There have been several rumors accusing that the update will be delayed, but Buterin has been updating the community regularly and has assured the users a couple of days ago that the development is on track and is not even delayed by a single day. I hope Ethereum will be back in price $1,000 on 2020.
