What a clickbait title ! Anonymity is not leaving Bitcoin ! You can still buy your bitcoins with cash and get covered without any problem ! Only sale is monitored on South Korean exchanges, which represent, let me remind you, a very minor part of the world volume.
And some exchanges that implemented the KYC compliance policy, title is a self-explanatory that cryptocurrency is no anonymous yet the Op stated some facts from a country who pulled off some exchanges to support the thread, it is not the coins itself who are not anonymous, you can still perform transactions not just in bitcoin but on any other coins as long as it is not requiring some information anonymously, some multi-platform web wallets and local exchanges already implemented this compliance in order to eliminate abuses.
