The financial privacy of the Chinese crypto community has been continually evolving, with the government implementing various regulatory measures to control the use of cryptocurrencies and monitor transactions in the crypto space.

The situation became even more complex with China’s plan to introduce a central bank digital currency (CBDC). While the digital Yuan is intended to enhance payment efficiency and reduce transaction costs, some Chinese citizens perceive it as a means for the government to exert greater control over payment systems and surveillance of users’ activities.

This article provides insight into China’s cryptocurrency landscape and suggests a solution to maintain a crypto user’s privacy and anonymity despite the stringent crypto regulations.

The Current State of Cryptocurrency in China

China was among the first countries to quickly embrace cryptocurrency, opening BTC China, its first cryptocurrency exchange in 2011. In 2013, Bitcoin was initially accepted as a form of payment. Large-scale Bitcoin mining operations began in China in 2013 and grew into an industry in 2017.

Coincidentally, it was also in 2013 when the Chinese government initiated its crackdown on cryptocurrency, expressing concerns that cryptocurrencies could destabilize the Yuan, its fiat currency. As of September 2023, cryptocurrency is considered illegal in China.

The Regulatory Landscape

China’s restrictive stance against cryptocurrency aims to protect the nation’s economic system and halt financial crimes, including fraud and money laundering. Below is an overview of the Chinese government’s regulations against cryptocurrency.

Cryptocurrency Prohibition

The restrictions began on December 5, 2013, when the People’s Bank of China (PBoC) and other government agencies and watchdogs, such as the Ministry of Industry and Information, jointly prohibited banks and other financial institutions from dealing in cryptocurrency.

Initial Coin Offerings (ICO) Ban

ICOs were declared as illegal fundraising activities in September 2017 to combat scams associated with ICOs.

Crypto Exchange Shutdown

Following the ICO ban, the Chinese government directed local crypto exchanges to voluntarily shut down. Some exchanges like BTCC and ViaBTC closed down, while others moved overseas. This resulted in a significant drop in crypto trading activity in China. However, some Chinese crypto traders found ways to bypass the ban by using offshore exchanges for their trading activities.

Crypto Trading and Mining Restrictions

In May 2021, Chinese authorities restricted crypto mining and trading due to concerns about its energy-intensive nature and its impact on China’s environmental goals. The mining ban had a global impact because China generated approximately 50% of the world’s Bitcoin mining power. In September of the same year, crypto trading was banned, declaring all cryptocurrency investments, trading, and transactions on local or foreign platforms as illegal.

Challenges and Risks

The cryptocurrency market worldwide is susceptible to market volatility, posing the risk of financial losses for crypto investors. The Chinese crypto community faces additional challenges, summarized as follows: capital flight concerns, lack of regulatory predictability, CBDC threat, and social media censorship.

Let’s delve deeper into each one.

Capital Flight Concerns

China has strict capital controls to manage the movement of funds outside the country, aiming to maintain economic stability. To achieve this, Chinese authorities impose limits on how much money individuals or businesses can transfer out of China.

In pursuit of privacy and anonymity, Chinese citizens and businesses have turned to cryptocurrencies to circumvent these controls by moving funds overseas through cryptocurrencies instead of using the traditional banking system. Recognizing the potential of cryptocurrency as a capital flight instrument, Chinese authorities resorted to restricting ICOs and closely monitoring crypto exchanges to address their concern about capital flight.

Central Bank Digital Currency (CBDC)

China has been developing its CBDC, known as the digital Yuan, since 2014. The digital Yuan is not a cryptocurrency; it is a fiat currency under government control. Transactions in digital Yuan are faster because they bypass banks, and advanced technologies in its design prevent counterfeiting, illegal duplication, and transaction falsification. However, unlike cryptocurrency, which aims to provide anonymity, the digital Yuan’s design intends to combat financial crimes and track down perpetrators.

Lack of Regulatory Predictability

The Chinese government has sent mixed signals regarding its stance on cryptocurrency. Despite the crackdown on crypto trading and other crypto activities, it has invested in blockchain research and development and explored blockchain technology in finance and supply chain management.

In a recent news report, Chinese courts have recognized cryptocurrencies as legal property. However, individuals involved in crypto activities in the country still face severe penalties.

Social Media Censorship

China is known for its tight control over Internet content and social media platforms through its Great Firewall. The system restricts access to foreign social media platforms and websites. China has developed its own social media ecosystem, including WeChat and Weibo, which are under government control and vulnerable to content filtering and monitoring. This means all crypto- related activities on the Internet are closely monitored.

These factors give the Chinese crypto community ample reason to be concerned about their privacy and anonymity. But why is financial privacy important to them?

The Significance of Financial Privacy

Financial privacy is crucial for individuals and businesses in the cryptocurrency space, but it holds even greater importance for the Chinese crypto community which faces several challenges and risks. Financial privacy safeguards individuals and businesses from malicious actors who might exploit their crypto funds or attempt to hack into their crypto holdings. Given the prevalence of cyber- attacks, fraud, and scams in the crypto space, robust encryption and other financial privacy features are needed.

Additionally, Chinese crypto users value financial privacy to protect their crypto assets from government surveillance and to participate in the crypto market without fear of facing legal repercussions. They want control over their financial assets, data, and strategies without any external interference.

While the Chinese crypto community highly values financial privacy, the government’s regulations against cryptocurrency and related activities in the mainland have posed a threat to that privacy.

The Importance of User Education

Every cryptocurrency user must be well-informed to manage the inherent risks associated with investing and trading in cryptocurrencies. With the increasing number of frauds and scams, user education becomes even more critical so that users can easily recognize danger signals and protect themselves from financial losses. Similarly, awareness of security measures, such as hardware wallets, strong passwords, and two-factor authentication, empowers users to prevent hacking and theft.

Specifically for the Chinese crypto community, user education entails understanding the various laws that govern the use of cryptocurrencies. This knowledge allows them to conduct their crypto activities without violating these laws and to safeguard their financial activities and transactions from government scrutiny.

Privacy is a fundamental right, and individuals who understand how cryptocurrency works, the associated risks, and the regulatory framework, are better equipped to exercise their autonomy, financial freedom, and privacy rights.

Understanding UniJoin’s Bitcoin Mixer

An essential aspect of user education is knowing the tools that can help navigate the complexities of the crypto landscape and the related regulations. One such tool is the Bitcoin mixer such as UniJoin.

What is UniJoin?

UniJoin is the leading crypto mixer that promises privacy and anonymity to crypto users through the use of CoinJoin technology. In addition to Bitcoin, it will be also able to process mixing with Ethereum, Litecoin, and Tether in the future.

UniJoin allows crypto users to invest in cryptocurrencies in restricted countries, securely store funds in their digital wallets anonymously, shop online, and transfer funds to other users without being traced by third-party individuals.

This reliable Bitcoin mixer immediately deletes logs after the mixing process is completed, ensuring that no user data is retained. This feature provides an additional layer of protection, concealing transaction details from scrutiny. Supported by the Tor browser, UniJoin enhances anonymity by allowing users to enter the platform as anonymous users.

Both beginners and experts find UniJoin easy to use. Launched in 2021, UniJoin enjoys a high trust rating and has built a good reputation within the Bitcoin community.

How Does it Work?

UniJoin mixes users’ Bitcoins with those of others in a single pool before breaking them into a single transaction. Each user within the pool provides coins as inputs and identifies anonymous receiving addresses as outputs. This process eliminates any link between the input and the output, ensuring that a recipient cannot trace from which input corresponds to the output and vice versa.

Benefits of UniJoin’s Bitcoin Mixer for Chinese Users

UniJoin offers several potential benefits to the Chinese crypto community which faces various challenges and risks.

At the top of the list of these benefits is user privacy and anonymity. UniJoin’s impressive features conceal users’ transaction history, granting them financial privacy. UniJoin also provides greater financial freedom by allowing users to avoid censorship and similar restrictions.

Another important benefit is security. Since transactions are untraceable, the risk of Chinese crypto users’ activities being detected, hacked, and attacked by cyber criminals is significantly reduced. The Chinese crypto community can also diversify its assets through UniJoin. By mixing their crypto assets before moving them to offshore exchanges, they gain access to cryptocurrencies that are banned in China.

UniJoin is a legitimate service, and its use minimizes the risk of legitimate users being linked to illegal activities. However, it is crucial to be aware of China’s laws and ensure compliance.

How UniJoin Can Protect You

UniJoin may offer several benefits, but can it truly protect the Chinese crypto community? Absolutely! Here’s how:

  • Letter of Guarantee: After a user sends coins for mixing, UniJoin provides them with a letter of guarantee, which is a digitally signed confirmation of its obligations. This document serves as proof in case a user raises a concern requiring verification.
  • Immediate Deletion of Store Logs: Information related to a mixing order is immediately deleted upon completion of the mixing process. The information becomes unavailable when the page is reloaded. Similarly, chat history is deleted upon the full resolution of a user concern.
  • UniCode: As no information is retained beyond the completion of the mixing process, UniCode serves as a reference to ensure that a user does not receive previously mixed Bitcoins from earlier CoinJoin rounds. The UniCode feature enhances privacy.
  • 24/7 Support: Users can chat with friendly and knowledgeable support staff to assist them with any concerns or difficulties they encounter with the UniJoin service, such as accidentally creating two transactions to one generated deposit address.

How to Use UniJoin: Step-by-Step Guide

There are five key steps to mixing cryptos using UniJoin.

Step 1

Create an anonymous digital wallet to store all your untraceable bitcoins.

Step 2

Visit the homepage and start creating your Bitcoin Mixing order by clicking on “Start Mixing” or click on the button below.

Start Mixing

Step 3

Input your anonymous digital wallet address into the designated field on the UniJoin website. You also have the option to input multiple addresses and subsequently determine the distribution of mixed Bitcoins to your designated wallet addresses.

Step 4

Select the desired wallet distribution and time delay.

  • Wallet distribution (only if 2 or more addresses have been put as receiving addresses) refers to the step in which the mixed Bitcoins are distributed back to the users. However, instead of sending the entire amount to a single address, UniJoin can distribute them across multiple wallet addresses.

  • For example, if a user initially sent 2 BTC for mixing, UniJoin might distribute the mixed Bitcoins as follows:

    0.5 BTC to Address A
    0.7 BTC to Address B
    0.3 BTC to Address C
    0.5 BTC to Address D

    You can establish the allocation percentages for distributing the mixed Bitcoins to the receiving addresses by adjusting the slider.

  • Time delay is a user-controlled feature. Users specify how many hours or minutes they expect to receive the mixed Bitcoins. It begins from the time a particular transaction has received two confirmations from the blockchain explorer. Increasing the time delay enhances anonymity, as it prevents prying eyes from linking the time of deposit to the payout time. UniJoin discourages setting the time delay to exactly two hours, as it can weaken the anonymity feature.

Step 5

Read all the terms mentioned on this page and accept them by ticking the boxes.

Step 6

Firstly, make sure to download the letter of guarantee as this file will be crucial to raise support requests on your order on UniJoin. After that, start your mixing order by sending the minimum amount of unmixed coins within the 24-hour timeframe. The deposit will be automatically recognized by the system and will start the mixing process as soon as your transaction has 2 confirmations on the blockchain. The minimum amount you can send to the pool is 0.001 BTC and the maximum is 1000.00 BTC.

Step 7

Receive mixed Bitcoins to your digital wallet. This will happen based on the time delay you specified.

Upon placing your first mixing order, UniJoin shall provide you with a Unicode, an auto-generated unique string that you use for all future mixing requests. The Unicode ensures that you don’t receive Bitcoins back from your previous mixing orders. The Unicode is another privacy-enhancing tool.


The cryptocurrency space is inherently complex to navigate, and stringent regulations, such as those implemented by China, amplify the challenges and risks it presents. However, the Chinese crypto community need not fear for the future of their financial privacy. With proper education and the right platform, their financial privacy can still be protected.
