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.
Being an anonimous person now,in the world of cryptocurrency is still excess, but there are some other circumstances also,that you must past a kyc for claiming your coins when you are a bounty hunters,or when you sign in some exchange trading that need to pass a kyc form,thats why there some countries need those exchange trading to pass there real name and account to prevent using the money in laundering or another illegal activities, so therefore i conclude that the sanctity of being anonimous is still there,but its only depend of which country that you belong.
