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.
Nothing has changed in the transaction monitoring till now. Government tracked the transactions before and is tracking the transactions today. They cannot track the transaction transfers between the crypto wallets but they can track the transaction to the FIAT. There are even more exchanges then before and because of that monitoring is inevitable.

There are more criminal activities than before and because of that authorities are suspecting on the crypto holders but that is actually the deceiving of the populations because the FIAT is actually the main asset for the money laundry and that same monitoring of the cryptocurrencies is actually a masked attempt to hide the money laundry that the government is doing.
