1.
Yin Zhentao, deputy director of the law and Finance Research Office of the Financial Research Institute of the Chinese Academy of Social Sciences, said that digital currency faces two risks. The first is the technical level. Digital currency relies on blockchain technology and a system, which will make it suffer from security impact, such as hacker attacks on computer systems. We have seen many practical problems in this process
Zhao Zhanzhan, a special researcher of intellectual property research center of China University of political science and law, believes that digital currency has anonymity, quickness and irrevocability. In addition, bitcoin and other digital currencies have high circulation in the world, so many criminals use digital currency as a new money laundering channel. Moreover, there are many different ways to realize money laundering through digital currency. Generally speaking, the probability of new money laundering being found and investigated is lower than before. Many countries have no effective means and technology to combat money laundering through digital currency. These factors lead to criminals prefer this way of money laundering

3. Digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
digital currency is a kind of unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form
according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk

4. Well, if you don't know whether it's safe or not, it depends on yourself. Otherwise, if you use it, the person who has used it may feel safe, and the person who hasn't used it may still be worried
5. The following is for reference only:
very large
in the field of blockchain and virtual currency, such cases of losses caused by the security of exchanges occur frequently, causing great economic losses to users. The security experts of Juhui ggfx also gave a hint: there are still many loopholes in the current digital currency trading platform, for example, the most common are the following six kinds:
the first kind: denial of service attack
denial of service attack is the most important attack against the digital currency trading platform at present. Through denial of service attack, the attacker makes the trading platform unable to access normally, Because users can not accurately distinguish the degree of attack, it often causes panic asset transfer, which brings some loss
the second kind: phishing
even the best technical measures at present can not make the digital currency trading platform avoid phishing attacks. Some hackers and outlaws can confuse digital currency investors by means of fake domain names or fake pages, while ordinary investors can't identify the authenticity, so it's easy to cause asset losses
the third: Hot wallet protection
many digital currency trading platforms use a single private key to protect the hot wallet. If hackers can access a single private key, they can crack the hot wallet related to the private key. For example, in the attack on yapizon of Seoul stock exchange in 2017, the attackers stole hot wallets from the trading platform twice in a year, resulting in a total loss of nearly 50% of the assets of the trading platform and eventually leading to the bankruptcy of the trading platform
Fourth: internal attack
e to the lack of perfect risk isolation measures or ineffective supervision on the authority of employees, the digital currency trading platform also has employees' self-monitoring and stealing, and some employees with operating authority of the platform use internal trust to seek ill gotten gains for themselves. For example, in 2016, the event of employees stealing bitcoin on shapeshift caused a total loss of US $230000 to the trading platform by stealing and reselling sensitive information to others
the fifth: software vulnerability
the software vulnerability of digital currency trading platform includes single sign on vulnerability, OAuth protocol vulnerability, etc. At present, all countries have laws requiring banks or other financial institutions to implement information security measures to protect customers' deposits. However, e to the fact that the blockchain field is still in its infancy, there is a lack of such specifications for encrypting digital assets. Therefore, it is not accidental that many trading platforms have a large number of loopholes in the absence of security constraints
sixth: transaction malleability
Technical supporters of blockchain often think that blockchain transactions are highly secure because they are recorded on records that are said to be unchangeable, but each transaction needs to have a corresponding signature, and the records can be temporarily forged before the final confirmation of the transaction. Mt. GOx, which once accounted for 80% of the world's total transactions, was hacked to submit code changes to the public ledger before the initial transaction was released, resulting in a loss of 473 million US dollars< br /> &# 160;

7. That is to say, there is no central management institution, no state institution or organization, no beneficiary, public ownership, fairness, impartiality and openness.
8. At present, the size of bitcoin block is 1m, and it can only process about 7 transactions per second. With the continuous growth of bitcoin transaction volume, it is difficult for bitcoin network to confirm transfer transaction quickly, resulting in congestion in bitcoin network
there is a backlog of tens of thousands of transactions on the bitcoin blockchain, and the transaction cost of bitcoin transfer is as high as tens of dollars. When the network is congested, bitcoin transactions even take several days to be packaged. We started to discuss how to expand the capacity
since 2013, people have put forward a lot of schemes for bitcoin expansion. Some people say they want to raise the upper limit of block size, and some people say they want to take out some useless information in the block... But these schemes have not been widely recognized. As a result, the expansion of bitcoin has been controversial.

10. Risk 1: Limited trading rules. Before okex's point-to-point trading area, the digital currency purchased by RMB could not be directly transferred to the spot account for trading, but could only be traded in the point-to-point trading area
there are only a few large currencies in the point-to-point trading area, such as BTC, BCH, ETH, etc, LTC, and they can't withdraw the currency, so the direct purchase of digital currency with RMB is blocked. Fortunately, e to the large number of complaints, this restriction has been lifted
risk 2: the transaction process is not standardized. If you want to use RMB to buy digital currency for trading in the exchange, you must find the offline usdt team to buy it. Before purchasing, you need to carry out identity authentication. Besides the photos of the front and back sides of the ID card, you need to read a disclaimer by video. The time of releasing the currency is uncertain. If you want to the bottom, you have to see your luck
there is a great risk in the process of offline trading, because once there is any problem, it will make the sky should not call the earth ineffective. Fortunately, the legal currency transaction of usdt has been launched recently, so offline channels can be avoided as far as possible
risk 3: platform customer service. Okex's customer service is outsourced, and there are few things it can handle. Customer service calls are often blocked. If there is a real problem in the transaction, the customer service staff will pretend not to see it. The message sent yesterday may not reply to you today
risk 4: system stability. With more and more people speculating in currency, the matching mechanism of the whole platform is facing more and more challenges. In the past, a small number of people could play and cope with it, but now more and more people are. Recently, many people can't deal with the market price list in time e to matching, the market price is incorrect, and there is no way to cancel the order and other system problems. The platform will not deal with them, resulting in the loss of many people.
