My friend asked me to participate in digital currency

1. If you are recommended by people in the stock group, they have a commission. One person controls dozens of micro signals. It's true that there are only two or three people in each group. The others are trust. They live a good life in each group every day. Show a steering wheel, show a high-end villa or something. If you are male, they will add you with wechat of beautiful avatar. If you are a female, they will use wechat like a successful person to add you. Let you invest in digital currency from a friend's point of view. But you may not know that they have dozens of micro signals, or even play several roles. Once sold into the digital currency of informal platform, you can't think of it... Always think of "there is no free lunch in the world".

2. The Internet of things is a general term for an instry, such as automobile, rice, Internet and other instries. Only the people's Bank of China has the right to issue currency. Any other enterprise that issues currency is a pyramid scheme swindler. The original shares will not be issued in this way. It needs a professional securities company to operate. Other people say that the basic way to pay for the original shares is to cheat my friends to join the group called China Internet of things digital currency. Is this fake

3.

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

4. It's no use suing the recommender. They just recommend it, and they don't have to let you invest. You can only sue the investment company.

5. Recently, Huawei held a new proct launch of P30 in Paris, France, and released Huawei P30, Huawei P30 pro and other models. Since the cooperation with Leica in the first generation of p9, Huawei's "P Series" seems to have become a synonym for Huawei's camera phone. At the press conference, Yu Chengdong also focused on the introction of the photo taking function of P30 series, and compared the dark light environment shooting ability of P30 pro with that of iPhone XS Max and Samsung S10 plus

in the early days of the emergence of mobile phones, people have great expectations for the configuration, style and function of mobile phones, so it is easier for mobile phone manufacturers to carry out differentiated positioning

however, with the continuous maturity of communication technology, manufacturing process and configuration, the homogenization of mobile phone instry is becoming more and more serious, and it is difficult to seek differentiation. So the mobile phone brand began to look for a demand that the majority of users are concerned about. As a frequently used function in smart phones, taking photos has been concerned by all parties

in addition, the rise of mobile Internet makes social platforms and social software hot. In the era of 2G and 3G, the data flow is low and the camera pixels are poor. Although there are social platforms, they are far from popular. In the 4G era, all kinds of social networking platforms are rising rapidly, and we media is exploding. People's desire for expression is unprecedented, and they all hope to show themselves more in online social networking

in addition, with the improvement of economic level, the frequency of people's travel and entertainment is increasing, so self photography, landscape photography, high-definition video shooting and other behaviors are becoming more and more frequent. How to take more beautiful and higher style photos has become an issue of great concern. And these behaviors have a certain degree of requirements for photography ability. Mobile phone manufacturers conform to this trend and focus on the photography function

however, smart phones and professional camera equipment have their own advantages. The advantage of smart phones lies in portability, and professional camera equipment lies in its professionalism. They have their own advantages, and the comparability is not so strong. Therefore, it is inevitable that there will be some disputes if we insist on putting the two together

however, it is undeniable that the smartphone's emphasis on the photo taking function has indeed caused a great impact on the traditional photography equipment market. Even if it can't really compare with the professional photography equipment, the smartphone has made great progress in the photography function, such as double camera, four camera, night camera, deep camera... The photography technology of the smartphone is improving at a visible speed, and each stage is further away from the professional

for most non professional photography users, the camera function on the mobile phone is enough. In the eyes of most ordinary consumers, the shooting ability of mobile phones can completely replace photographic equipment. With more than 90% of mobile phone manufacturers using Qualcomm chips, it is easier to see the effect by working hard on the camera function. In order to highlight the brand differences, and to meet the needs of users, today's mobile phone photo functions are rich and diverse, which more "devour" those potential users who may be professional photography equipment. Therefore, it is a wise choice for mobile phone manufacturers to focus on the photo taking function.

7. Normally, there is no problem, but we still need to confirm the link, because now there are many people posing as public security organs, so we should be careful.

8. Ventilation, air pressure, drainage and lifting are collectively referred to as the four major mining machinery, which are also the main large-scale mechanical equipment in mine proction. Its daily maintenance, inspection, and equipment installation quality have a considerable impact on its life experience. Especially the quality of equipment installation is directly related to the failure rate, material consumption and service life ring service. With the continuous development of the proction level, the single machine capacity of mining machinery is also increasing, and the accuracy requirements for the installation quality of mechanical equipment are also improving. Any mechanical equipment, from arriving at the installation site to putting it into operation and proction, must go through the following installation process: equipment open box inspection and acceptance, handling and lifting, foundation acceptance and setting out, equipment marking, equipment in place, leveling and alignment, equipment fixing, disassembly, cleaning and assembly, grouting adjustment and commissioning, until the project acceptance and other processes

(1) strengthen the maintenance of crusher equipment to prevent errors and leakage. Since maintenance is not the main cause of equipment failure, maintenance work must be carried out. Maintenance and management personnel make effective maintenance plan for the mechanical maintenance manual, and check the implementation at any time according to the technical instructions of the machine and the driver. And establish a reward and punishment mechanism, reward the good and punish the bad, strengthen the responsibility of drivers, infrared carbon sulfur analyzer, mobilize their enthusiasm and enthusiasm, do a good job in maintenance, ensure the normal operation of mechanical equipment and other nursing work from the source, and prevent maintenance support

(2) strengthen the daily inspection work of crusher equipment, the test results should be recorded in detail, not only including the previous maintenance records, and put a record, but also including the daily use and workload of a record, so as to analyze and judge the mechanical fault, and eliminate the hidden danger timely and accurately

(3) the maintenance management personnel should timely grasp the situation, understand the overall situation, make a reasonable and detailed mechanical maintenance plan, make the maintenance instruction and supervision of maintenance business, procurement activities, and avoid unnecessary maintenance and cost waste.
