Digital currency contract with a single routine

1. 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.

2. Is it true that someone in my circle of friends has issued large-scale digital currency loopholes to cash out? I don't think you should believe it. At present, the central bank is at an adaptive stage, and there are still many immature aspects.

3. At present, our country does not recognize digital currency as a kind of "turn a blind eye", which neither recognizes legality nor illegality. However, it is said that it seems to recognize the legality of digital currency now, because our country is also advocating its own digital currency

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

5. The risk of digital currency platform is great. I can't believe what they say. I have to judge for myself. I have enough experience to enter.

6. 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.

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
