Bitcoin has recently received attention from outside the circle one after another, but none of them are good things.

Two weeks ago, it became a hot search on Weibo because of the sharp drop, and in the past two days, it has once again attracted attention because of "Room N".

Originally, Xiao Pai didn't pay much attention to the "Room N" incident, thinking that it was just an ordinary SQ video spread on the Internet. Later, because several South Korean exchanges assisted the police in the investigation, and the core operator "Doctor" Zhao Zhubin (transliteration, 24 years old) mainly accepts digital currencies such as Bitcoin and Monero, so he paid attention.

Just looking at it made Xiao Pai disgusting, how could there be such a perverted person in the world.

It's really a thousand dollars. I won’t describe Xiao Pai in detail. If I talk too much, I don’t know which pervert will imitate it. It is simply an abuse and humiliation of women beyond human nature.

South Korean police have as many as 74 female victims, 16 of whom are minors, and the youngest one is an 11-year-old elementary school student.

What is even more infuriating is the collective annihilation of humanity. The "Room N" incident lasted from the second half of 2018 to March 2020, with as many as 260,000 paying users. Who would have thought that this "collective crime" involving 260,000 people would last so long. If it weren't for the undercover investigation by reporters, it is unknown how long it would have lasted. Is there no one in the middle to report it? It is simply a collective loss.

What is the concept of 260,000 people?

The total population of South Korea is only 51 million, which means that 1 in every 200 people will participate in this "crime".

It is said that the number of taxis in South Korea is about 260,000, which means that if you wave casually on the road, the person who may come to you will be a member of "Room N".

South Korean President Moon Jae-in ordered a thorough investigation of the "room N" incident and asked the police to investigate all members of the chat group. South Korean netizens launched a petition on the Cheong Wa Dae website. As of 17:00 on March 24, the number of petitioners requesting the disclosure of the identities of the perpetrators and members of the chat room has exceeded 4.4 million, making it the largest petition in Korean history. The South Korean police disclosed the identity of the main criminal and found hundreds of millions of won in cash at his home.

According to South Korean media reports, the payment standards for "Room N" opened on Telegram are 200,000, 600,000, and 1.5 million won (equivalent to 1,149 yuan, 3,448 yuan, and 8,620 yuan), and most of them use bitcoin transactions.

According to the level, the operator will provide content of different scales. The videos are also categorized with tags such as "female nurse, female teacher, female middle school student" for users to choose.

The charges were settled using a digital cryptocurrency, which was made more difficult to investigate because Telegram's security system is already very strict.

It is said that the principal criminal, Zhao Zhubin, has 513 cryptocurrency wallets, and a total of 3 personal cryptocurrency wallet address accounts disclosed in the "Doctor's Room", one of which has an amount of 3.2 billion won (about 18.39 million yuan).

"Doctor" accepts digital currency when paying, and he thought it was safe and secret, but he probably didn't think that Bitcoin has no privacy at all. All transaction records of cryptocurrency are traceable. Once the receiving address is known, the address of the transfer to this address can be found, so that the funds can be easily found through the address and IP and the real-name authentication information of these addresses on the exchange. people who come and go.

At present, South Korean cryptocurrency exchanges, including Bithumb, have received a notice from the police, asking them to assist in the investigation of the "Room N" case. Bithumb stated that it is identifying the relevant user list and promised to actively assist the police investigation.

On the 20th of this month, the South Korean police seized and searched a cryptocurrency sales agency, and obtained a list of members who purchased cryptocurrency through the agency company and sent it to the "Dr. Zhao" account. A manager of the company said: "About 100 people transferred Monero to Dr. Zhao's account in our place." currency users.

Dr. Zhao received two cryptocurrencies, Bitcoin and Monero, at the same time. Since Bitcoin is more popular, it is expected that more people who have transferred Bitcoin can be found. Compared with Bitcoin, Monero has stronger anonymity, and Bitcoin is easier to track transfer personnel through exchanges. At present, mainstream exchanges in South Korea are actively cooperating with the investigation of the "Nth Room" case and Dr. Zhao.

At present, millions of Koreans have petitioned to disclose users' personal information, and there are many posts on Korean websites, saying that it is a crime to see "Nth Room" only after they started together, and then delete it permanently.

It is hoped that the South Korean police can consider semi-disclosing the information of these users, at least to put various information of users including DNA into the database, knowing that the potential possibility of these people engaging in crimes in the future is very high.

In fact, it is a well-known fact that Bitcoin and anonymous coins are used for illegal transactions. Xiao Pai wants to fight against the injustice of Bitcoin, technology does not distinguish between good and evil, the key is to see who is being used. In the hands of villains, any technology in cash can be turned into a tool for doing evil.

To some extent, the traceability of digital currency is also helping the police to destroy the underground dark web.

For example, in October last year, the US and South Korean authorities stated that they had destroyed one of the world's largest child pornography websites through Bitcoin tracking, and had arrested hundreds of people around the world and rescued at least 23 underage victims. It is reported that this website called Welcome To Video sells child pornography videos, which can be paid with Bitcoin, and has now sold 250,000 videos describing child sexual abuse using cryptocurrencies.

The website is run by a South Korean named Jong Woo Son, who is serving an 18-month prison sentence in South Korea where he will face charges from U.S. authorities. Several other accused individuals have been convicted and sentenced to up to 15 years in prison, according to the U.S. Department of Justice.

Prosecutors said they located the criminals by analyzing the blockchain and deanonymizing bitcoin transactions, as well as by locating servers.

According to PANews, in a survey of 31 darknet markets, it was found that Bitcoin is still the most popular cryptocurrency on the darknet, followed by Monero and Litecoin. About 93% accept Bitcoin as payment, and more than 44% of sites offer Bitcoin-exclusive support. In addition, the average number of cryptocurrencies supported by each market is about 2.4. Monero is also a digital currency accepted by Dr. Zhao.

Monero is the only asset other than Bitcoin that also has the exclusive support of darknet markets. For example, Whitehouse Markets and Monopoly Market are markets that only support Monero. Their reasons for doing so are:

• Whitehouse Markets: "Bitcoin lacks the necessary privacy and some users don't know how to launder their coins, or don't even realize they have to."

• Monopoly Market: "When dealing with government agencies, we must assume that they have a complete database or have the ability to contact the exchange to obtain any information they want. After all, this is also the effect that KYC regulation hopes to achieve, that is, to trace to the end , to see who bought what. Monero is a countermeasure to solve this problem. Through Monero, you can safely buy bitcoins in any necessary channel, including providing your ID card to the exchange. This is not only easy to operate , and the prices are more affordable, as sellers who don't require ID tend to bid up their prices for the risk factor.
