1. It's not worth it
bitcoin is no longer easy to dig, and it is much cheaper than before
maybe you can only dig for a few hours a day and lose money
even if you mine with a high configuration computer in your own home, it is estimated that you will consume a little more electricity, not counting the aging depreciation of the computer.
2. 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.
3. Bitcoin, the current price of bitcoin is 83000
the biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system had no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million.
4. Do you want a bitcoin client or a bitcoin
mining tool? Bitcoin mining tools can be used to network "bitcoin cgminer"
5. 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 strong>
6. You need to share invitations, download friends, browse news, read novels, watch videos, etc., to earn gold coins and then change them from gold into WeChat coins or Alipay, or directly recharge phone bills, Q coins, etc., which requires WeChat WeChat real name authentication. So it's not easy to make money by mobile phone. Some software has high threshold and earn a phone fee. Or find a job to earn more than this, but also exercise themselves, often play mobile phone is not good for the body, their discretion to consider it
7. [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.
8. Bitcoin is very slow and has a certain amount. Generally, it's a professional miner's fee, electricity fee and computer fee. It's better to dream when you are young
9. Bitcoin is now in a state of fire. We have a certain understanding of the fact that a lot of information about bitcoin has been searched at this time< but I didn't expect that nearly 20% of Internet cafes in South Korea chose to dig for bitcoin at this time, because the occurrence of bitcoin surprised us all because we all understand that for bitcoin, the virtual currency, its overall price still makes it impossible for us to make a specific estimate, because it is not affected by the current macroeconomic regulation and control{ RRRRR}
so this tells us that when we encounter such things in medical life, we should understand them, otherwise it will be very bad for us and it also tells me that we should keep an understanding attitude when we are not in the state. This is what we all understood and imagined in the past. So this also tells us that we should pay attention to things like charm, which we can all imagine and understand
