1. Let me tell you the answer first: No
or don't invest all of bitcoin. Let me give you a brief analysis
first of all, let's talk about 100000 yuan. If the 100000 yuan is a windfall, we suggest that you allin invest in bitcoin, which may be several times more when you take it out at the end of this year. There will be another windfall
if the 100000 yuan is a year-end bonus, you can consider investing half of it in blockchain and bitcoin
if the 100000 yuan deposit is your hard-earned money, you must be cautious in your investment, so first of all, you are not recommended to invest in blockchain
in fact, your question tells me two basic facts: 1. You are Xiao of blockchain / currency circle; 2. You have a little deposit and want to manage money, or you need to make some money
so from my point of view, I don't recommend you to buy bitcoin or make any other blockchain investment, because there is a saying that a person can't make money beyond his cognition, and the blockchain world is beyond your cognition for you, and the coin circle is basically an extension or part of the financial system. And the financial system is the most cruel and ruthless world. When you want to make money, you should also think that there are hundreds of thousands of people, millions of people who have the same ideas as you, so as to drive them into this bloody and merciless market. So you ask yourself, can you make sure you make money
first pour a basin of cold water on you, and then answer your questions seriously. Let's take a look at the historical trend of bitcoin
I feel optimistic that the recovery may come slowly, the Federal Reserve's move may be the beginning of financial release, and the capital market may recover slowly. As a small part of the financial market, the blockchain world may also recover
from the perspective of investment, bitcoin in the blockchain world is not only the genesis currency, but also the mainstream currency that accounts for the vast majority of the total market value at present. Therefore, if you really want to invest in the blockchain world, bitcoin is the best choice
however, please note that from the perspective of professional investment advice, risks should always be shared. Exclusive bitcoin will be taken off by a currency, and it will also fall miserably. So please consider holding other mainstream currencies, such as BoChang coin, which is known as "the last good heart of the blockchain", which is also the most powerful counter trend growth currency in the bear market of the currency circle. For a long time, when the mother of other currencies, including bitcoin, didn't know each other, BoChang was the only currency that was growing slightly, which was a miracle
another example is Ethereum. Although Ethereum's hard fork has been delayed for a long time, the arrival of Constantinople's hard fork upgrade will make Ethereum the most eye-catching star in a short time. At this time, the investment can be regarded as low-level market entry, and you can make a profit by waiting for high-level investment
finally, back to my answer, if you don't even know wave field, bitcoin, Constantinople hard fork and other words, how can you determine whether you can make a sum of money in the world of currency. So this in itself is a very high risk thing
a strange capital market will swallow up all your savings. Although some people get rich overnight, they are a few people after all. If you are sure to invest in the blockchain world, bitcoin can be invested. However, from the perspective of risk sharing, please buy some other mainstream currencies to minimize the risk. Finally, I wish you a happy investment and a big fortune in the year of the pig. Please be cautious in your investment
is to read more about the various currencies or project's white paper. I pay attention to my WeChat official account: "Nanjing block chain" can get thousands of white papers free of charge, so that you will have a better understanding of the chain world. p>
2. The price of commercial housing has soared all the way. In such a big environment, now a house is close to one million. When buying a house, there are many factors to consider. A house must live for at least several decades. Therefore, when buying a house, the first thing is to know about the real estate; Secondly, they should have their own opinions, otherwise they will be easily fooled by the sales staff. The following is a senior sales Miss revealed the details of buying a house
The low rise houses are close to the green belt of the community, and the invasion of mosquitoes can not be avoided in summer
to sum up: when buying a house, we should consider all these factors carefully, otherwise we will only regret it

3. 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.
4. [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.
5. Hello, this is also called "miner" fee. The "absenteeism fee" is charged for confirmation on the blockchain. Although IDC wallet does not charge for sending and receiving
digital currency, it is recommended to pay for blockchain to ensure that your transfer arrives in time.
6. Since Qin Shihuang unified currency, currency has become an unattainable thing in our life. In ancient times, we all exchanged things for things, and finally developed to use today's currency, which makes our life much more convenient. However, in addition to our commonly used currency, some people must have heard of bitcoin as a virtual currency, And this kind of currency is very precious, not everyone has it, but there is a person in China who has 100000 bitcoins in his hand
all this is e to his unique vision at that time. If 100000 bitcoins were converted into RMB now, it would be 5 billion. At that time, no one thought that a virtual currency might have such value. What's your opinion
7. This year, bitcoin will halve for the third time. The first half was on November 28, 2012, when the price of BTC was US $12.2, with an increase of 134.62% in the first half of the year; Half a year after the proction rection, the currency price reached US $128.8, up about 955.74%, and the highest reached US $230.7, up about 1790.98%
the second time occurred on July 10, 2016, with the currency price of US $650.3, up 51.30% in the first half of the year; In the half year after the rection, the price of RMB rose to US $892.5, or 37.24%, and the highest rose to US $11354.5, or 1646.04%
since the beginning of this year, bitcoin has been rising. From January 1 to February 13, BTC rose by 43.56% to US $10329.18, reaching the highest of US $10405.8, successfully holding the 10000 yuan pass, and the rising trend is very obvious. 'I believe that the price of bitcoin will exceed $100000 in the next two years, and I stick to that prediction,' former bitcoin China CEO Bob Lee said in a recent interview. In the end, I believe the price will reach 1 million or more, which is the biggest investment opportunity in our life
however, the bitcoin market fluctuates strongly, and any investment will be accompanied by risks. It's better to test your risk tolerance before investment, because bitcoin investment depends not only on the market, but also on the attitude of investors, and resolutely refuses the gambler style. Finally, we wish all the people in the coin circle a big profit in 2020.
8. Bitcoin is a private concept coin without any material support, which is not recognized by financial institutions and has no value. It does not conform to the characteristics of currency and will not be recognized by the state. It is just a quarrel. Investment is not worth it. Speculation depends on your level. No online trading token in China is valuable, including q-coin. It is only valuable for use and will never be recognized by the state. They don't form the medium of financial transactions at all.
