Is digital currency binding on Lao Lai
on September 4, 2017, the people's Bank of China and other seven ministries and commissions issued the "notice on preventing the financing risk of token issuance", which cleaned up the ICO and virtual currency trading venues. The scale of domestic virtual currency transactions decreased significantly, effectively avoiding the impact of virtual currency prices on China's financial market.
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
Many central bank governors voice the trend of digital currency, bitcoin will not replace other legal currencies in the end. 1. There is no way to regulate bitcoin, which hinders monetary policy. 2. The global circulation of bitcoin can make many criminal organizations launder money with the growing popularity of the Internet, bitcoin has attracted more and more attention, and many big men have begun to build bitcoin platforms, which makes many people have high expectations of bitcoin, and bitcoin has also seen a significant rise. Central bank governors of many countries are talking about the trend of digital currency. Bitcoin will not replace other fiat currencies in the end. The main reason is that the decentralization of bitcoin leads to no government being able to manage and control bitcoin, which makes it easy for bitcoin to become a money laundering tool for many criminals, thus affecting the development of the country, This is also the most direct reason why bitcoin can not obtain legal tender digital currency is a currency that can be controlled by the state or the government. This kind of currency is very different from bitcoin. The state recognizes digital currency, but there is no national recognition of bitcoin, which is the real reason why bitcoin will not replace legal currency in the end

according to the investigation of China Youth Daily · Zhongqing online reporter, the "two barrels of oil" and "Li Gui" in Zhejiang market are not as simple as a rumor refuting announcement. A company in Guangdong also organized an attack on "China oil card" on social media
"in the past, when Shanzhai gas cards were overturned in other areas, we felt that they were far away. This time, the" Zhongyou card "went straight to Yongtaiwen area in Zhejiang Province, making people feel more nervous than ever before." Jiang Zhiyong, director of the gas station management department of PetroChina Zhejiang sales company, said with the publicity materials distributed at the news conference of the Wenzhou Branch of "China Petroleum card"
in the business hall of Sinopec Cixi gas station, a man told a woman that after running Sinopec gas card, he could download an app on his mobile phone, register and bind the gas card, and get 4000 yuan discount by recharging 15000 yuan through the app. The staff of the business hall reminded the lady not to believe in such preferential activities
claims that it is a large-scale comprehensive wealth platform based on Internet plus energy and employment, and its members are both consumers and market promoters, thus achieving mass employment and entrepreneurship. Ordinary consumers who download the "Zhongyou card" app on their mobile phones must input their mobile phone number, verification code, and the name and mobile phone number of the previous introcer. They can only register and log in after strict audit
"'petrochina card 'does not issue cards at all, nor is it based on Sinopec's platform and system operation. Instead, it parasitizes its business model on Sinopec and other regular gas cards, and in addition, it pulls a group of people and develops a system to expand everywhere." Relevant personnel of Sinopec Zhejiang oil company's Publicity Office said that its essence is to let Sinopec and PetroChina "carry the black pot"
the relevant business departments of Sinopec and PetroChina Zhejiang company said that it was "impossible" for the "CNPC card" to promise the high return of recharging its members. According to the sales revenue and cost data of gasoline and diesel provided by the company, taking the air recharge of 15000 yuan for 4000 yuan package as an example, 15000 yuan can add more than 2400 liters of gasoline
"two barrels of oil" business department related staff pointed out that Shanzhai gas cards often take the money from home to make up for the price difference, drum style continues to develop new members. What's more, when members reach a certain scale and amount of capital, they can make up the capital gap with the return of investment in other fields, in which the potential legal risk and capital risk are very large
in recent years, with the rapid development of the Internet and social media, all kinds of fake gas cards come out in a variety of ways, and become "little strong" repeatedly. In 2012, the company launched a PC version of its official website, and some Internet experts imitated the webpage and linked to "phishing" websites to defraud customers of their top up money
WeChat official account, some people registered "petro technology" and "micro refueling" for their lives. They announced that they would get "Sinopec" thanks to the message that they could get the 200 yuan Sinopec fuel card free. Within a short time, the news was wildly forwarded in the circle of friends, and Sinopec Ningbo Branch's gas card customer service hotline constantly received calls from customers to inquire about and verify the problems such as the return of pre charging fees to cash
then, a "China Petroleum Reserve" card suddenly appeared in Zhejiang, claiming that as long as customers fill up gas at Sinopec and PetroChina gas stations, issue invoices, take photos and upload them to the app platform, they will rebate according to the preferential amount“ The "zhongchu oil" card didn't run for long before it went out of business. Now Zhejiang has another "Zhongyou card"
"the most important thing is that the cost of breaking the law is low and it is difficult to crack down on."“ "Two barrels of oil" related staff said that even if Sinopec and PetroChina outlets monitored the market for fake gas cards, they would at most issue a public statement, or even be unable to report the case to the police. Because "the one who is injured will report", Sinopec and PetroChina are not direct victims and cannot report to the police
recently, Sinopec and PetroChina informed Taizhou market supervision and Administration Bureau of the suspected false publicity and other relevant information about the opening of "PetroChina card" in Taizhou. After on-site investigation and evidence collection, the law enforcement officers of the Bureau ordered them to rectify the behaviors beyond the scope of business license. However, a person concerned told China Youth Daily · Zhongqing online that "the business of" Zhongyou card "in developing members' air recharge has not stopped because of this."
