Java digital currency multi angle strategy source code

1. It has to be said that this instry is very close to money, so people often ask how you make money in the instry and how you can make money. Today, let's share some profit models I know<

first line: mining, mining machine, mine (ore pool)
all three are related to mining, but they are also different

Mining: we don't discuss the technical details here. From the perspective of profit, mining has the lowest threshold. Even if we need professional mining machinery now, we can still buy a mining machine to make money. If we become bigger, we can open a mine. Without talking about the risk, mining is the simplest way to make money. The investment cost is low, the rate of return is high, and the time cost is high

mining machinery: the business of manufacturing mining machinery is very hot, and there is a high threshold, so it is difficult for non professionals to become manufacturers. Ant mining machine in the bull market does not worry about selling. Especially after 1994, as far as I know, foreign domestic ore feeders were towed away by trucks. However, the threshold of manufacturers is already very high, and it is difficult for ordinary people to get in touch with them, so there are two dealers. Mining business contact is not much, the second-hand market seems to be very chaotic

mines (ore pools) of course, mines and ore pools are inseparable. Why? The mine pool exists in order to avoid the risk of the mine. The mine pool will pay the cost of the miners according to the time according to the calculation force. Of course, it also needs to draw a percentage, and the miners will be able to keep their income from drought and flood. But the only thing to do is to bring people to the mine. Offline mines are also managed by their own machines, and can also be managed by others. There is a certain threshold, risk and income coexist

second line: information platform, exchange, wallet, currency speculation

consulting platform: something that must exist in the Internet era, providing information and consulting aggregation. The first thing new people come into contact with is information media. In the 17 years since the outbreak of digital currency, bitcoin's Internet search index has exploded. Many people want to know about digital currency, so such an information platform is sure to survive. Drainage, content, value realization and value extension are generally the ways of making profits

exchange: the best understanding is that all flows and proction currencies are for trading. Only when a transaction has a price can it be valued. Many problems will also be found in the transaction, such as the famous "bitcoin expansion". Only by finding and solving problems can the instry develop better. We all know the mode of making money in the exchange. It's the makers who make money. It's just like casinos and securities dealers. They lose more money and earn less, but the exchange is stable. In addition to the handling charges, it seems that the money charge is also a profit model. The threshold of the exchange is also high. In addition to trading risk and platform risk, it pays more attention to policy dynamics. Big exchanges now have "currency exchange", "fire currency" and so on

wallets: both hot and cold wallets are procts, and coin circles are just needed for this kind of procts. Online wallet is generally free, and then through other ways to make money, such as usually do exchanges, or there are investment activities

currency speculation: simple speculation, uncontrollable risk, too many factors affecting the price. We can envy the good luck of others, but we should not hope that we have such good luck. Therefore, there are generally three modes of currency speculation, which can be more "smart" to avoid risks: 1. Fixed investment 2. Quantitative trading 3. Arbitrage: spot move brick, futures arbitrage. Now, it seems that there is a fourth kind of profit margin in the OTC channel.

3. We should focus on three aspects: popularity, innovation, operation mode and team

popularity: there is no doubt that bitcoin and lightcoin have the highest popularity in the cryptocurrency circle. Even though they have many shortcomings, they still have the largest number of players and the highest amount of money. They have large plates and are not easy to be controlled by the makers. Of course, the relevant infrastructure is relatively perfect

Innovation: dog coin is popular because it caters to the western small reward culture. The reason why Fuyuan coin can become the leader of the new generation of cryptocurrency is that it mainly focuses on the currency business circle, which is an applied cryptocurrency

operation mode: for example, the operation mode of Vicat coin has been exposed as pyramid selling. Although Yuanbao coin has been criticized before, the operation team will not give up, and Yuanbao coin is still the leader of domestic currency.

4. Digital currency is still very little to quantify. It seems that Mars asset bank is doing it. You can refer to it first

5. WinRAR, password in more than 8 bits, a bit more complex, basically difficult to crack.

6. On the okex contract transaction page, there is an option for policy delegation (price limit delegation, plan delegation, tracking delegation, iceberg delegation, time weighted delegation). The system can delegate automatically according to the parameters set by the customer in advance. The logic of all policy delegation is fixed logic, which is explained in detail in the description document. After the customer sets the parameters and delegates, it will be executed automatically, In the process of policy implementation, okex will not intervene in the actual implementation of the policy
before the trigger condition is reached, the policy delegation will not actually register the order in the disk, nor will it lock the asset share that the user can use. If the trigger condition is met and the order cannot be placed normally e to insufficient user assets, the system will automatically revoke the policy delegation.

7. There is a parameter in the sort method of the policy pattern

collection, and you need to write your own implementation.

8. 1. Java is a compiled language, because it can't run directly without compiling the source program. It's just that Java is compiled into intermediate binary code, not the final machine code

2. There are such compilers, such as gcj of GNU for free and excelsior jet for charge. However, it is not necessary to use it. Java will also dynamically optimize the intermediate code into local machine code at runtime. The result of this optimization is generally better than that of pre compilation, because dynamic optimization can dynamically select optimization strategies according to the running conditions of programs and computer hardware.

9. At present, Java language is the most stable. High end OA, such as UFIDA pan micro, are all developed with Java. For all languages, see the following

there are many OA software development languages. At present, there are five common languages: ASP / PHP /. Lotu Domino /. Net / Java. Each of the five languages has its own characteristics, and the most distinctive one is that they represent the "brief history of computer language development and use"< ASP language
1. ASP is Microsoft's initial web proct, which was introced to the market in 1997. It is an early web language technology. Many small and simple websites are developed with ASP language. Because it is a proct of the 1990s, after the computer language upgrade, its biggest problem is that its scalability is relatively poor, It's very difficult to connect with the mainstream computer languages. Net and Java, so we often see that many small websites developed with ASP language technology face problems such as upgrading after 2003. Finally, many companies have abandoned the previous ASP language structure procts to use the latest language technology to develop websites
the biggest headache for software engineers is that it is impossible for ASP technology to connect with. Net platform (the author has experienced the transformation of ASP website into. Net website in the past, which can be described as "suffering"). Due to the long history of ASP language, it is not widely used in the newly developed system. The OA software developed by ASP language that can still be seen in today's market is mostly improved on the basis of procts proced before 2005< At present, the procts developed with ASP language are: Jinhe
2. PHP
PHP and ASP are basically procts of the same era, but the maturity time is slightly later than ASP. PHP language is slightly more complex than ASP in development. Its biggest advantage is that its version is a free and open platform just like liunx system, and open source code is easy to find, In this way, it solves the problem that the developers rack their brains to write the program. Because it is open source, many programs can be found on the Internet, but the right problem and security problem are the two problems that have plagued PHP technology. There have been many pirated versions of Tongda OA in China. In fact, the root of the problem is the open source of PHP (you can refer to Tongda's official website)
like ASP, around 2000, PHP became the mainstream development tool for websites. The advantage of PHP compared with ASP is that it has better cross platform performance. However, when facing large-scale user groups or portal websites, PHP has some problems. So PHP technology is also going downhill. PHP language is still used in many websites, but the mainstream application system has shown the trend of abandoning the use, and the basic level is fading out of the selection range of development tools
currently, OA procts using PHP technology include: accessible, pan micro eOffice
e to the open source of PHP and the ease of use of ASP, as well as the long history of its language technology, there is a fact that many colleges and universities and computer language vocational training schools have given up or begun to give up using PHP and ASP for teaching, which determines that PHP language technology is becoming an updated proct, There are difficulties in upgrading in the future, and there may be great risks
as an attractive point of marketing strategy, many OA software using PHP and ASP technology impact the market with the strategy of low price. In fact, OA software using these two technologies is more applied to low-end procts
3. Lotus Domino
is a popular OA development tool developed by IBM in 1996. Its advantage is that the development speed is relatively fast. It is developed based on Lotus script and integrated with lotus mail system. It is mainly used for workflow and internal mail delivery. Due to the special document database system adopted by roots, the efficiency of query and data statistics is relatively low, Integration with relational database is not good. So Lotus Notes is a good architecture for a single message and workflow system, but it will be very difficult to do large-scale business integration or business development
the biggest difficulty of OA procts using lotus notes language architecture is that it is difficult to integrate business systems. In 1997, I saw IBM promote the louts system in Beijing. Maybe there are many people who understand the louts language abroad, but in fact there are few people who understand the louts system in China. This is one of the reasons why the louts system has been unable to open up in China's domestic market, because there are few technical engineers who understand the louts language, Therefore, the biggest difficulty of the software procts developed with louts language is to upgrade and maintain. The cost of the system engineer is relatively high
domestic OA procts using louts language: Heqiang
the above three language technologies used to be web or mainstream development languages in the 1990s, but with the continuous upgrading of computer language technology, these three language technologies graally fade out of the sight of people developing OA software, The number of technical engineers using these three languages also shows a decreasing order of magnitude. Maybe by 2020, the engineers of ASP and PHP language technology will become the "rare language animals" in the world. Only then will the engineers of ASP and PHP language get much more salary than the mainstream engineers
4. Net
at present, one of the mainstream technologies of computer language in China, there is a phenomenon that you can see from the recruitment advertisements of software companies. From the recruitment advertisements, we can see that more and more recruitment targets are technical engineers of Java and. Net, It is not difficult to see from the market heat that Java and. Net will represent the mainstream of development languages for a long time in the future
the way to prove whether it is the mainstream reason is very simple. First, whether there is the support of large international manufacturers. Second: scalability, scalability, molarity, object-oriented and so on. The security and stability of the proct development and the scalability of the proct development. Of course, there is no way to visualize scalability, upgradability and molarity. For those who are interested in OA language, they can't help but read more books on computer language technology. In fact, each book introces the balanced advantages of Java and. Net in expansion, upgrade and molarity. Third: there is also a simplest verification method, that is, you can ask your friends who have done research and development or know something about computer language technology, and they will give you a clear answer
. Net language development software proct stability is higher, the proct can be molar is a fact advantage, but. Net has a strong advantage at the same time, there are also some disadvantages, such as cross platform, big data concurrency. At the same time. Net and ASP docking, will lead to low proct security,. Net platform security will be with the ASP security vulnerabilities for hackers or criminals to use and then destroy, this has been plagued by software engineers one of the biggest problems. Net language and ASP docking one of the biggest factors. Of course, if. Net does not need to dock with ASP language, then there is no such risk.
