Transaction fraud of digital currency contract

1. A number of victims of virtual currency fraud cases distributed all over the country said that they were refused to file a case when reporting to the local police because virtual currency could not be valued and could not reach the starting loss amount of theft or fraud. This situation may be affected by the announcement on preventing the financing risk of token issuance issued by seven ministries and commissions on September 4, 2017 (hereinafter referred to as the announcement). Generally speaking, fraud and other crimes of infringing property rights have the starting point of "large amount" According to the interpretation of the Supreme People's Court on Several Issues concerning the specific application of law in the trial of fraud cases, indivials who defraud public or private property of more than 2000 yuan belong to "large amount". However, the announcement clearly pointed out that "any so-called token financing trading platform shall not provide pricing, information intermediary and other services for token or virtual currency." Therefore, it is difficult for the public security organs to recognize the price of virtual currency displayed on the trading platform, and to estimate the value of virtual currency when the victims encounter virtual currency fraud, so as to determine whether the case meets the filing standard.

2. Can solve withdrawal recovery, do not panic, keep good chat records, transaction records and other evidence. Find a regular rights company to help you recover. Most of the domestic platforms are not up to standard, try to avoid operation, not greedy for huge profits! In fact, if you are cheated by black platforms such as foreign exchange and options, don't be afraid to lose heart. If you collect your own rights protection materials in time, you can recover them. Deposit records, transaction records, bank flow and so on are all vital rights protection materials. Before the platform is completely shut down, recover the principal.

digital currency is a new technology that can be used to improve transaction efficiency, but now it has been targeted by some lawless elements and carried out marketing and fraud in its name, using ordinary people's ignorance of digital currency to deceive investment and investors

Generally speaking, we investors or cheated people should prepare the following evidence:

1. The chat records between relevant chat records and analysts or agents or order calling personnel are the most basic evidence, because such evidence can fully reflect the whole process of our cheated people being cheated and the illegal places of relevant business personnel in the chat process, Can be fully reflected in the chat record

2. The evidence of relevant deposit and withdrawal records is the deposit and withdrawal of the bank account of the investor or the cheated person, which can reflect the investment and withdrawal of the cheated person, and the difference between the two is basically the total capital loss of the investor. This kind of evidence can be preserved by the cheated basically, just go to the bank and print the bank account

the above evidence is the basic evidence that investors or cheaters should have, but not all the evidence. In the process of power only, if there is no or incomplete basic evidence, then the difficulty of power only will increase, but the light of justice is still willing to take up the weapon of law to help you safeguard your vital interests! Willing to give the most professional legal aid! Promise only right is not successful, do not charge the slightest fee

4. At that time, I was also in the wechat group. Hongfeng and his group broadcast live every day to take you to speculate in stocks. They found a cheater to say that he was a big man and took you to digital currency. Fortunately, I saw the digital currency fraud before and didn't fall for it. But in the end, I lost more than 20000 when I bought stocks. I don't know if they were caught by the police. It's hateful. What's more hateful is that the scam they are searching for now is the advertisement pursued by the law firm, which is estimated to be another scam.

5.

The contract transaction of digital currency is not safe. There are still many loopholes in the digital currency trading platform, for example, the most common are the following six kinds:

1. 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

2. Phishing incident

even the best technical measures at present can not make the digital currency trading platform avoid phishing attacks. Some hackers and criminals 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

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, e to the lack of perfect risk isolation measures, or ineffective supervision on the rights of employees, some employees who have the operation rights of the platform use internal trust to seek unjust wealth 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

Fifth, the software vulnerability of digital currency trading platform includes single sign on vulnerability, OAuth protocol vulnerability and so on. 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

6. Transaction malleability the 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 forged temporarily before the final confirmation of the transaction

rules of contract transaction

1. Transaction time

contract transaction is 7 * 24 hours transaction, which will be interrupted only ring the settlement or delivery period of 16:00 (UTC + 8) every Friday. In the last 10 minutes before delivery, the contract can only be closed, not opened

Transaction types are divided into two types, opening and closing. Opening and closing positions are divided into two directions: buying and selling:

buying open long (bullish) refers to buying a certain number of contracts when users are bullish and bullish on the index. Carry out "buy open more" operation, match success will increase long position

selling pingo (multi order closing) refers to the selling contract that the user makes up for when he is no longer bullish on the future index, offsets with the current buying contract and exits the market. Carry on "sell flat much" operation, match after success, will rece long position

short selling (bearish) refers to the new sale of a certain number of certain contracts when the user is short or bearish on the index. Carry out the operation of "sell short" and increase the short position after successful matching

buy close (short single close) refers to the buy contract that the user will not be bearish on the future index market and make up for, offset with the current sell contract and exit the market. Carry out "buy short" operation, after matching successfully, short position will be reced

3. Order method

limit order: the user needs to specify the price and quantity of the order. Limit order can be used for opening and closing positions

order at opposite price: if you choose to order at opposite price, you can only enter the order quantity, not the order price. The system will read the latest competitor price at the moment of receiving the entrustment (if the user buys, the competitor price is the selling price of 1); If it is a sell, then the counter price is buy 1 price). Issue a price limit order for this counter price

4. Position

the user owns the position after opening and trading, and the positions in the same direction of the same contract will be merged. In a contract account, there can only be 6 positions at most, that is, multiple positions of current week contract, short positions of current week contract, multiple positions of next week contract, short positions of next week contract, multiple positions of quarterly contract and short positions of quarterly contract

5. Order restriction

the platform will restrict the number of single user's positions in a certain period of contract and the number of single open / close positions, so as to prevent users from manipulating the market

when the number of positions or entrustments of users is too large, the platform has the right to require users to take risk control measures, including but not limited to cancellation of orders, closing positions, etc. The platform has the right to adopt measures including but not limited to limiting the total number of positions, limiting the total number of consignments, limiting the opening of positions, withdrawing orders, forcibly closing positions, etc. for risk control

6. The best way to prevent being cheated is not to be greedy, or to send money to them instead of being bullied
never trust a phone call with unknown origin and money borrowing.
if you can't distinguish it clearly, you can call 110 to report the case, and the police will screen it.

7. You can call the police, because many of the digital currencies issued in China are illegal fund-raising activities. The Ponzi scheme in the guise of blockchain usually means that the people in front earn the money of the new entrants in the back, and the platform profits from it. However, these funds have a running cycle, and they will collapse when the time comes
2. Digital currency is an alternative currency in the form of electronic currency. It is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community

it is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currencies, such as bitcoin, lightcoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography
on October 13, the International Monetary Fund predicted that global GDP would shrink by 4.4% in 2020, up 0.8 percentage points from the forecast in June. This year, China remains the only major economy the IMF expects to achieve positive growth< Tobias Adrian, head of the IMF's monetary and capital markets department, said in an exclusive interview with China first finance and economics reporter recently that China's economic recovery is leading the world, while the pilot of the central bank's digital currency (DCEP) is leading the world. He believes that at present DCEP is still focusing on M0 (cash in circulation), which has little impact on banks. In the early stage, DCEP will pay more attention to the application in China. In the future, as more countries begin to pilot central bank digital currency (CBDC), the cross-border use and convertibility of CBDC will be concerned

recently, the promotion of global central banks' digital currency is accelerating. Some mainstream central banks have changed their conservative attitude in their early years and accelerated the research on CBDC. China has taken the lead in carrying out relevant pilot projects. At 8:00 on October 11, Shenzhen "Lixiang Luohu digital RMB red envelope" booking ended, and the system successfully completed the pilot booking registration, which is an important step in the development process of digital RMB

Adrian said: "China's digital currency pilot is leading the world, and the IMF is closely following the pilot situation of China's digital currency in some urban areas." From the perspective of monetary statistics, the central bank's digital currency belongs to the category of M0, that is, cash, not M1 or m2. Therefore, he does not think it is necessary to worry about the impact on banks in the initial stage.

8. All transactions take place on the blockchain
once a transaction occurs, the blockchain itself cannot make any changes unless both parties negotiate under the chain, which is the "non tamperability" of the blockchain. Therefore, 91token can not complete such operations as "private key loss recovery", "encryption password recovery", "account freezing" and "transaction rollback"
if you transfer to the wrong address of the exchange, it is recommended to contact the official office of the exchange.

If you are cheated, you can choose to report to the police in time for recovery

digital currency is an emerging technology that can improve transaction efficiency, but it is targeted by lawless elements to carry out pyramid selling and fraud in its name. The official website of the monetary Bureau of the people's Bank of China issued the risk warning on issuing or promoting digital currency in the name of the people's Bank of China. The central bank indicated that recently, indivial enterprises falsely used the name of our bank

falsely claimed that the central bank issued digital currency promotion team in an attempt to deceive the public and take the opportunity to make huge profits. The central bank has not issued legal digital currency, nor has it authorized any institution or enterprise to issue legal digital currency

extended information:

the so-called "digital currency" in the market is not legal digital currency. At the same time, the so-called "digital currency" launched by some institutions and enterprises and the so-called promotion of the central bank's issuance of digital currency may involve pyramid selling and fraud

They are: treasure money, Baichuan money, SMI, MBI, mark money, dark money, mmm, Fuda compound interest financing, etc
