It is no surprise that anonymity has been leaving bitcoin. Bitcoin is not as anonymous as it used to be.
Monero the more anonymous bitcoin has been getting a lot of news as it is being used for many illegal purposes such as drugs and money laundering.
South Korea today, however, is increasing regulation on all cryptocurrency exchanges as reported by
https://revoltmedia.org/south-korean-new-rules-on-cryptocurrency/.
South Korean laws passed this morning are now only letting South Korean exchanges accept users if the user has real-name bank accounts connected.
Regulations like this are the first of many soon to come that will try to take anonymity from cryptocurrency.
The South Korean government reasoning was to prevent money laundering and other illegal activities.
I don't think that the title is valid at all. Crypto currencies are anyway not anonymous because this is what bitcoin.org says here :
All Bitcoin transactions are stored publicly and permanently on the network, which means anyone can see the balance and transactions of any Bitcoin address.

With that said, I'm pretty sure same principle is followed by the different alt coins too. I can just easily scan the ETH address on the etherscan.io and checkout the balance, history of transaction and much more. So thats not anonymous at all.

That may or may not be true but that doesn't change the facts of cryptocurrency principles like its anonymous, it can't be used for money laundering etc.
