Security of digital currency transaction

1.

Basic routine: the "trading market" of MLM digital currency is basically controlled by specific institutions. In order to attract investors' investment in the early stage, the currency price may be very high. Once the time is ripe, it will be sold intensively, and the price will plummet, and the investors will lose all their money

There are three characteristics of digital money MLM:

1. Digital money is a real proct, and it is highly packaged

2. The participants can get a head pulling reward, and the prize is the digital currency itself

3. Digital currency will appreciate with the increase of participants in the scam. In the cycle of digital currency appreciation, the number of participants who can obtain digital currency will also increase, and the participants, including the lowest level participants, will also gain, but in the cycle of devaluation, the bottom level participants often lose a lot

in 2017, the Internet Finance Association of Jiangsu Province issued the "internet pyramid selling identification guide", which named 26 so-called digital currencies as illegal pyramid selling projects covered or suspected to be covered with digital currency. They are: treasure money, Baichuan money, SMI, MBI, mark money, Diablo money, mmm, Fuda compound wealth management, carat money, V treasure, Vicat money, petroleum money, Huaqiang money, CB aiib Hong Kong Group, Yuansheng, Morgan money, beta money, WorldCom, u money, Jubao, 21st century fox, Wanxi wealth management, Wanfu money, Wuxing money, Yi money, Zhonghua money, etc

five ways to distinguish whether digital currency is pyramid selling currency:

1. Issuance mode

virtual currency does not rely on specific monetary institutions. It is proced by a large number of calculations according to specific algorithms, and is a decentralized issuance mode. 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 spontaneously formed in the market, which is graally completed by a third party establishing an exchange after the scale is formed. The MLM currency is issued by an institution and traded on its own platform

3. Implementation method

virtual currency itself is an open source program, which is maintained in 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

4, whether to give the source code link

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. The MLM currency focuses on the transaction process of recharge purchase, but does not mention its operation mechanism. Even the website does not have the link address of the source code

5, whether the official website starts with HTTPS

generally, the addresses of the official website and trading website of decentralized digital currency start with HTTPS, and the purpose is that this kind of website can well protect the user's data from illegal theft. But the official website of MLM currency, trading website and other related websites do not start with HTTPS

2. Digital currency transaction is not safe, investment should be cautious.

3.

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

4. It depends on what kind of exchange it is. There is no problem with the big ones, such as the coin net in the fire coin net. It is suggested to be careful with some small platforms. If satisfied, please accept

5. It's the same as P2P. It depends on the platform. Of course, the big platform is safe. It's the small platform that has an accident. The leading ones in the global trading volume of digital currency exchange are all right, like fire money.

6. Another risk of digital currency is credit risk. Because there are middlemen in digital currency transactions. Therefore, many criminals use digital currency as a new money laundering channel

7. It's a fraud platform. I've reported it on the official website of the Ministry of public security! Everyone who has been cheated should report to the police!

8. First of all, you have to make sure that you are operating on the international mainstream digital platform to ensure the security of the transaction

9. I think it's safe,
