How does Ethereum see long and short after ups and downs
money, as a measure of transaction value, does not necessarily have value in itself, it can only be used as an intermediate unit of measurement. It's just like China has only RMB as legal tender, that is to say, government guarantee has value. For example, in those war-torn areas, ten jin currency may not buy an egg, which is the reason
back to digital currency, digital currency, until now, no country has recognized it as the currency in circulation of its own country. It seems that last year or the year before last, our country also banned some. In this case, digital currency can only be sold at a price higher than your purchase price, so that you can make money. But digital currency itself does not have any value. Unlike stocks, it is your ownership of listed companies. So if you can't find someone to buy digital currency, it's worthless
the Ponzi scheme in history, the Dutch tulip, when it was the most expensive, a tulip was worth buying a house. When no one bought it, all the tulips rotted. In addition, they couldn't get a potato. Therefore, Buffett said that digital money is a bubble, which is a hoax.
in addition, there is a saying in the stock market that when all the ladies in the vegetable market begin to discuss the stock market, it is the time when the stock market reaches its peak. In my opinion, this also applies to digital currency. When many people are discussing how to make money and how to make a lot of money, the risk has accumulated to a great extent. Most of the time, when the stock begins to fall, many people are still in the previous inertial thinking, thinking that it will rebound soon, and then it will get lower and lower, and they are more reluctant to sell it. This is why many people hold a high position on it
I'm not sure whether it is the highest point of digital currency, but I think that digital currency, which can be issued by anyone, has no purchase value and can only be sold to others. I think it's a fraud.

Its trading behavior is characterized by selling before buying. In fact, it's a bit like the credit trading mode in business. This mode can make profits in the band where the price falls, that is, first borrow and sell at a high level, and then buy and return after the price falls.

ESB is a combination of traditional middleware technology, XML, web services and other technologies. ESB adopts the mode of "bus" to manage and simplify the integration topology between applications, which is a standard integration mode between loosely coupled services and applications
Functions of ESB:1. Service Oriented Architecture - distributed applications are composed of reusable services
2. Message Oriented Architecture - sending and receiving messages between applications through ESB
3. Event driven architecture generates and receives messages asynchronously between applications
extended data
Application of ESB in different fields:
1. Telecommunication field: ESB can fully support the application integration concept of OSS in telecommunication instry. It is an ideal carrier level application software platform
2. Electric power field: ESB can fully support the data integration concept of EMS in electric power instry, and is an ideal data exchange platform for SCADA system
3. Financial sector: ESB can support the process integration concept of business processing platform between banks and enterprises in an all-round way, and is an ideal B2B transaction support platform

Our country can introce a series of policies to resist the virtual currency, and also can make the virtual currency disappear in our country. Our country does not approve of virtual currency, and our country will not support the development of virtual currency in our country
as a member of virtual currency, bitcoin has actually won the attention and support of many people before. Many people especially want to invest in bitcoin, but bitcoin has plummeted. Bitcoin collapses again, breaking the $40000 mark. Is virtual currency trustworthy? In my opinion, virtual currency is not worth believing. There are three reasons why it is not worth believing: first, virtual currency is a fraud
in fact, I don't think virtual currency is worthy of our belief, because virtual currency is a fraud. Virtual currency is not only the operation means of those capitalists, but also the carrier of those capitalists who want to get more money. In fact, there are manipulators behind the virtual currency, and those manipulators also hope to get more revenue by manipulating the virtual currency, and also hope to make more money. This is a particularly big fraud{ RRRRR}
that's my opinion
if you have multiple systems and these systems are heterogeneous, for example, some are developed by Java, some by. Net, and some by C / s, for example, tuxedo, etc There are also mature procts such as SAP, etc.
If I want to integrate these heterogeneous systems, it is very suitable for ESB
the role of ESB is protocol conversion and service routing
protocol conversion means: for example, TUXEDO middleware has services exposed to the outside world, and its services are a special format protocol, ejp used by system a, etc Web service used by system B, servlet used by system C, email used by system D, RMI used by system E, etc.
at this time, these systems can be connected to ESB, and they can be converted to web service for other parties to call
