1. bitcoin is just a game. If it is promoted as a tool to get rich, it can be regarded as a fraud. Just like the currency in other online games, the only difference is that bitcoin has been standardized since the game was first formulated. It can't be issued indiscriminately, so it can keep its value better than other virtual game props. It is equivalent to the online collection. Bitcoin is a prop in the game, and its value is reflected in the recognition of bitcoin by players: more people play, the value of props in the game is higher; The risk is that he is not the only game, and his algorithm is not the only one. Maybe someone will be able to make other special coins soon. All you need to do is promote the game and sell your props. As for money, bitcoin does not have the basic attributes of money, such as unfair initial distribution and insecure circulation. Money needs to be maintained by the state machine
< H2 > extended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked
4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30

2. First of all, in the friend interface of your transfer, click the "complaint" button in the upper right corner, and then click in and select "there is fraud and money fraud"
then there are the ways and reasons of money fraud. You can choose. After selecting, the wechat team will ask you to submit relevant chat evidence. At this time, you must remember to save more screenshots, The more evidence you have, the more likely you will be cheated.
after you submit it, you should take double insurance based on Xiaobian's experience. Search "wechat team" in the wechat search box again. After you click send message, there is an abnormal feedback in it.
after you click in, fill in the things you have been cheated, such as the screenshot of Xiaobian, and check the relevant options, This time, you need to fill in the supplementary description about yourself, such as how much money you were cheated, when you were cheated and why you were cheated:
after you have written your situation clearly, don't forget to submit your screenshot again, so that the general backstage of wechat team will have a clear judgment on your feedback, The last step is to report to the police and ask the police uncle to help you investigate the whereabouts of the funds. Of course, the same important thing is the screenshot evidence you provide, as shown in the screenshot of Xiaobian, and submit the relevant evidence to the police uncle, So as to take the method of freezing the other party's account to avoid the loss of funds
after the steps are completed, you just wait for the wechat team to contact and cooperate with the police's relevant investigation, and actively provide relevant information, so that your funds can be recovered as soon as possible!
3. The essence of quasi currency is decentralization, anonymity, security, open source, and so is
blockchain. Because the price volatility of digital currency has always been large, it is impossible for users to put their digital currency in the centralized exchange for trading or let the centralized institution manage it on their behalf, because it is not convenient, and it also causes great security risks to users, so the virtual currency wallet developed with blockchain Technology has come into being
in the existing mainstream development enterprises, only a few of them can use the blockchain technology to develop the virtual currency related procts like Yingtang Zhongchuang, and there are many development schemes for reference.
4. in short, bitcoin is a virtual currency . Like stocks, it can be invested and traded. In technical terms, bitcoin is a kind of P2P digital currency
but after all, the nature and mode of bitcoin is different from other currencies, and it may prosper in the future. It may also be like the collapse of the economic bubble, which is unknown. If you enter the bitcoin market and have a quarrel, it will not become a real currency, because the fluctuation of the price is impossible to satisfy everyone. If there is a profit, there is a loss. Therefore, the investment of bitcoin should be cautious. If you don't fully grasp it, don't try it easily
5. In fact, there is no very accurate definition of microservice architecture, which roughly describes a large complex software application system composed of several microservices. Each microservice in the system can be deployed and expanded independently, and each microservice can provide a stable mole boundary. Each micro service is loosely coupled, micro service is very small, focusing on one thing. Microservice framework has good technology heterogeneity, flexibility and scalability. Its simplified deployment provides a huge impetus for continuous delivery. But it also brings some challenges, such as distributed transaction consistency, network performance consumption and so on. Therefore, the selection should be combined with the actual business considerations. If you want to further study, it is recommended to use some ready-made open-source microservice frameworks of some large manufacturers to develop a trial hand. You can use spring cloud and servicecomb. There are a lot of online materials. I hope this answer will be helpful to you.
6. [editor's note] some developers may still not understand how useful docker is to themselves, so this article will introce the use cases of docker in the development process of ordinary developers. Nowadays, docker has won a lot of attention. Many people think it is difficult to live up to its reputation because they still can't figure out the relationship between docker and ordinary developers. Many developers feel that docker is far away from themselves. Docker is a tool in the proction environment and has nothing to do with themselves. It took me a long time to figure out how to use docker in my own development as an ordinary developer. Frankly speaking, I am still in the process of learning. This article provides a list of docker use cases, which I hope will help you better understand docker and arouse your thinking. This article only describes the daily application of docker in ordinary developers, and does not provide a complete solution. Before introcing use cases, I hope you can remember this sentence: "docker is a portable application container". You may not know what docker means by "portable container", but you must know that docker can bring great efficiency improvement in daily life. When you need to run your own application (of course, any application) in the container, docker provides a basic system image as the basic system for running the application. In other words, any application on Linux system can run in docker. Can I run the database in docker? Certainly. Can I run node.js web server in docker? Certainly. Can I run API server in docker? Certainly. Docker doesn't care what your application is or does. Docker provides a set of methods for application packaging, transmission and deployment, so that you can better run any application in the container. I often use the following examples myself. Of course, you can share better examples with me. To try new software, it is necessary for developers to try all kinds of new technologies, but developers are not likely to build a good environment and test them one by one. Time is very precious. Thanks to docker, we can build the environment in one or several commands. Docker has a foolproof way to get software. The background of docker will automatically get the environment image and run the environment. It's not just about building a new technology environment to get docker. If you want to quickly run a MySQL database or a redis message queue on your laptop, you can do it very easily with docker. For example, docker only needs one command to run MySQL database: dockerrun-d-p3306:3306tutum / MySQL. Translator's note: Although MySQL database can be installed very quickly by using commands, docker is a very good choice when using the latest technology or very complex technology. For example, gitlab takes ordinary users about one day to build gitlab platform, while docker only needs one command. Now I often need to do one or two demonstrations to customers and others with my own development results on weekends. The process of building demonstration environment is very troublesome. Now I find that docker has become the most reasonable way for me to demonstrate these tools. Meanwhile, for customers as like as two peas, I can directly provide Docker images to them without having to do any work of environmental configuration, and the effect will be exactly the same as they can see in their presentation, without worrying about their environmental configuration that will cause our procts to be unable to run. Avoid "I can run on my machine." this is mentioned in both the enterprise deployment docker described in the previous article and the personal docker use case in this article. Because of the different environment configuration, many people will encounter this situation in the development, and even the developed software can not run on the tester's machine. But that's not the point. The point is that if we had a reliable and distributable standard development environment, our development would not be as painful as it is now. Docker can solve this problem. Docker image will not be unable to run because of the change of environment, nor will it have different running results on different computers. It can submit docker images containing applications to testers, so that "it can run on my machine" will no longer happen, which greatly reces the time cost of developers and testers checking machine environment settings with each other. Another area where docker can be useful is training classes. In addition to the isolation of docker container, we can realize that the advantage of docker lies in environment construction. Everyone who is new to the training class has to spend a lot of time on setting up the environment, but if docker is applied here, we just need to distribute the standard running environment image, and then we can start the class. Using docker is as simple as using virtual machine, but docker is more convenient and lightweight. At the same time, we can also tell the students: "at the same time of training, we will also learn the most popular technology - docker". This win-win outcome, why not. Learning Linux scripts may seem strange, but it's a good opportunity for people who are not familiar with Linux operating system and shell scripts. Even if this article is not about Linux, the importance of Linux is still self-evident. If you are using windows, then I give you a suggestion: rent a virtual machine from the virtual machine provider: I recommend using the virtual machine of coreos system. Although this will not let you become a professional Linux operation and maintenance, it can let you quickly learn the basic knowledge of Linux, fall in love with the command line operation, and graally start to be familiar with and appreciate Linux. To make better use of resources, the granularity of virtual machine is "virtual machine", while the granularity of docker is "restricted application". Comparatively speaking, docker occupies less memory and is more lightweight. For me, this is an advantage of docker: because I often run multiple docker applications on my own computer, using docker is simpler, more convenient and more granular than using virtual machine, and can continuously track the state of containers. If you've been following technology news, you've heard of the concept of "microservices.". Docker can be well combined with micro services. Conceptually, a microservice is a part of the function that provides a whole set of applications. Docker can always act as a container for microservices in the process of development, testing and deployment. Even the proction environment can deploy micro services in docker. Migrating between cloud service providers, most of the cloud host providers have fully supported docker. For developers, this means that you can easily switch cloud service providers, and of course, you can also easily move your local development environment to the virtual machine. There is no need to configure the local running environment and the running environment on the virtual machine once. Fully deploying docker (docker here and docker there) as a standard running environment can greatly rece the workload and generate bugs when the application is online.
7. men can be cheated by 5 million when they speculate in bitcoin, which fully shows that they have no strong sense of fraud prevention, are easily tempted by high returns, and lack relevant investment knowledge
since the price of bitcoin has soared, it has been favored by many investors. Among them, swindlers have also taken a fancy to this point, making use of the victim's psychology of greedy for cheap and wanting to get rich, so that many people are deceived
if you want to avoid being cheated in your life, you should have your own principles, don't believe in things like pie in the sky, and improve your awareness of prevention
First, enhance the awareness of fraud prevention and increase the knowledge of fraud prevention< p> Many people work and live in real life, it is difficult to meet a liar, so they will naively think that there is no liar around, their sense of fraud prevention is very weak, and they do not know how to distinguish a liar, so they fall into the trap of a liar. If you want not to be cheated, you should improve your awareness of fraud prevention, always alert yourself, increase your knowledge of fraud prevention, and see through the tricks of cheaters{ RRRRR}
to improve their awareness of fraud prevention, do not be greedy, and think calmly when encountering problems can effectively improve their ability of fraud prevention. If you have any other opinions, please leave a message to discuss
8. Holiday, children like to play mobile phones at home, we are usually busy with work, no time for children, these can be understood
bear kids buy bitcoin
a middle school student has nothing to do on vacation and wants to earn some pocket money usually I like to play with the computer and brush the video with my mobile phone. This day, middle school students brush to a video, it said that buying bitcoin can make money
by leaving your contact information, you can be a good friend at home, and the other party calls you customer service. Teach students to download software, register accounts and so on{ RRRRR}
What are our parents doing
it's a big heart to put 100000 yuan into a child's account we should at least care about our children. If the account is bound with the parents' mobile phone number and the account changes, our parents will know. That would have prevented it
parents of children who buy bitcoin obviously don't care enough about their children. if they communicate with their children after work every day, they will avoid cheating
