Digital currency contract two directions buy together

1.

We need to call the police. This belongs to currency fraud. We can't blindly trust the virtual investment platform that can easily earn a lot of money. Fraud gangs often use "small investment, big income" as t to let investors taste the sweetness first and then increase investment, so as to achieve the purpose of fraud

at present, the so-called "digital currency" in the market is not legal digital currency. 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. It is necessary for the general public to raise their risk awareness, invest rationally and prudently, and prevent the interests from being damaged

extended information:

five ways to distinguish whether digital currency is MLM currency. virtual currency does not rely on specific monetary institutions to issue, it is based on a specific algorithm, generated through a large number of calculations, is a decentralized way of issuing. Each different terminal node is responsible for maintaining the same account book, and the maintenance process is mainly to package and encrypt the transaction information by the algorithm, while the MLM currency is mainly issued by a certain organization, and the profit is made by pulling the head

2. Transaction mode. Virtual currency is a kind of sporadic transaction formed spontaneously in the market. After the scale is formed, the third party graally establishes an exchange to complete the transaction. The MLM currency is issued by an institution and traded on its own platform

3. The virtual currency itself is an open source program, maintained in the GitHub community. The parameters and methods of the total amount limit are shown in the open source code. The open source of MLM currency is completely ing other people's open source code, and there is no use of open source code to build programs, so its essence is controlled by the website like Q currency

Whether the source code link is given. The general decentralized digital currency will give the source code link in the prominent position of the official website, so as to show the operation mechanism of the monetary system openly and transparently. What MLM currency focuses on is the transaction process of recharge purchase, not to mention its operation mechanism, and even the website does not have the link address of the source code

5. Whether the official website starts with HTTPS. In general, the addresses of the official website and trading website of decentralized digital currency begin with HTTPS. The purpose of this kind of website is to protect users' data from illegal theft. But the official website of MLM currency, trading website and other related websites do not start with HTTPS

2.

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

3. For many people, the concept of digital currency is a mystery. But there is no doubt that digital currency is different from virtual currency. Virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency. In 2013, the central bank, together with five ministries and commissions, issued the notice on prevention of bitcoin risks, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, which do not exist in the form of currency and legal currency. At the same time, digital money is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes.

4. Chongqing jinwowo analysis and research: blockchain is based on the Internet, but its function is wider than the Internet. The main similarities of the two technologies are
:
(1) in terms of data transmission mode, the Internet and blockchain do not need centralized intermediary
(2) both technologies require users to access the Internet
(3) both technologies can meet the needs of multiple users in an organization.

5. The DC / DC mole is a DC-DC transformer. The so-called isolation and non isolation refer to whether a transformer is added after rectification and filtering.
the one with transformer is isolation, and the one without transformer is non isolation. Generally, the power supply is isolated,
the safety of isolation is higher, and the requirements of isolated devices are lower for design, Because the isolated power is sent to the power mole after the transformer step-down, the non isolated power is directly sent to the power mole through the 220 V, and the current power chips are isolated

Different colors of the cream have different effects, according to their own needs to choose

1, ivory white: suitable for some skinned people who need no more skin color correction. They use them to cover defects and pore, and create the effect of nude make-up. Some people, regardless of their skin color, rashly choose ivory white in order to make them look white. In fact, it's a big mistake. In this way, the skin color of their face and body is far from natural. Most of us are not particularly white, so we should be cautious.

2. Light skin color: darker than ivory, more suitable for our Asian skin color. The skin is not black or white, and tends to be popular. Choosing this color is not too wrong

3. Dark skin color: this color is more suitable for the dark beauty, which will make the skin white. Don't choose the color number with your own skin color

Soft pink: it is suitable for people with fair complexion but not good complexion. Soft pink can add color to the skin and make people feel better. People with dark skin should choose carefully, otherwise they will appear black and red

5. Purple: purple, which is very popular recently, can neutralize yellow. Girls with dark yellow skin can use it to brighten their skin and make their skin look healthy and bright

6. Green: specifically for reddish skin, covering red blood and pockmarks to make skin look clean and shiny

extended information:

isolation cream is an important item to protect skin. The essence of sunscreen is sun protection. The sunscreen used in isolation cream is the same as that used in sunscreen. It is usually divided into organic sunscreen and physical sunscreen

organic sunscreen and ultraviolet can transform the harmful ultraviolet into harmless; Physical sunscreen agents (titanium dioxide, zinc oxide, etc.) mainly rely on the principle of reflection to block ultraviolet rays

to sum up, black people choose black, white people choose white, close to their skin color, and colorful BB Cream / isolation cream can neutralize and brighten their skin color. The most reliable thing is to have a try at the store counter

The "perfect set of commemorative banknotes" includes ten Hong Kong dollars with a face value of 10 yuan, ten Australian dollars with a face value of 10 yuan, ten new Taiwan dollars with a face value of 100 yuan, and one 50th anniversary banknote with a face value of 50 yuan; A thousand rupiah worth only 0.5 yuan falsely claimed to be worth 300 yuan; The so-called "wrong currency" is actually the fifth set of RMB in the 1999 edition...

according to the Beijing News, in Soho modern city, Dawang Road, Beijing, some cultural companies selling commemorative coins and coins coax the old people to the company by collecting souvenirs for free, and then make them spend tens of thousands of yuan through sales promotion, Buy some cheap commemorative coins and even currency in circulation

Yes, you are right. Even the currency in circulation dares to sell as collection currency. It can be said that the routine of these companies is not clever at all, and even ridiculous, but Rao is so, many old people are cheated. For no other reason, these companies recognize that some old people have money, but they lack knowledge about money

This is obviously against the law. In essence, this is a fraud committed intentionally by taking advantage of the poor discrimination and market information of the elderly, which is suspected to constitute a crime of fraud. According to the criminal law of our country, the crime of fraud refers to the act of defrauding a large amount of public and private property by making up facts or concealing the truth for the purpose of illegal possession. In this regard, it is also necessary to carry out the corresponding special strike, find out and eradicate the relevant instrial chain; And the establishment of effective daily supervision, so that they do not dare to move their minds on the elderly

When we were young, our parents were our tutors; Today's elderly parents, in terms of social experience and cognition of new things, often become "children" who need to learn from us

in addition, the community, banks and other relevant institutions and departments can also organize some activities to care for the elderly, go deep into the elderly group, and explain the knowledge of prevention of being cheated. In a word, let the old people be "smart" and form a cognitive defense line, so that similar scams will not succeed easily
