Wang Fu talks about bitcoin video again

1. At present, there is no accurate definition of virtual currency in academic circles. Generally speaking, virtual currency is mainly issued by online game service providers to purchase game props, such as equipment, clothing, etc. But at present, the use of virtual currency has gone far beyond this category. Virtual currency can be used to buy game cards, physical objects and download services of some movies and software. There are even many websites providing two-way exchange between virtual currency and RMB, which makes virtual currency become a circulating equivalent exchange unit. In this sense, virtual currency is similar to voucher. At present, the virtual currency in China mainly includes Q currency, bubble currency, u currency, network currency, cool currency, Warcraft currency, Paradise currency, Shanda counting, etc.

2. The current situation of blockchain can be said that a hundred schools of thought contend. The good side is that the whole blockchain ecology has graally entered the era of "life application". The bad side is that the whole ecosystem is still in a very fragmented state. The following points are summarized for reference

1. There are a large number of block digital currencies, and the market is chaotic
now there are tens of thousands of digital currencies in the market, good and bad. Some currencies have a certain user base, while some are on the verge of death. What's more, some digital currency projects have no contribution code at all, and they are completely reced to money collection tools<

2. Coinage and distribution are separated
coinage and distribution are separated, so there are security risks in third-party software. There have been several such accidents in 17 years, with heavy losses

3. It consumes human and power resources
as we all know, many digital currency mining is a waste of power and human resources. Many different numbers of digital currency mining will cause a lot of resources<

4. The third-party ICO trading platform has great security risks
the ICO trading platforms of digital currency have emerged one after another, which are developed by the third party or independently, so there are great security risks

5. It can't blend with real life in real time
the block digital currency can't blend with real life and service scenes in real time. The whole process is hyped by many interest teams, and ordinary users can't participate in real time in daily life

these are the bad side of the current situation, and the good side is reflected in the continuous progress and attempt of the instry, for example:

the combination of various technologies: for example, the combination of blockchain and VR panoramic, resulting in the new concept of panoramic blockchain, and the combination of artificial intelligence and Internet of things, resulting in more valuable blockchain concept

the application of Tongzheng is more diversified: Tongzheng is an important part of the blockchain, which is most likely to blend with life, and its function also begins to diversify. For example, Tongzheng is used to do accurate advertising drainage and advertising management for businesses, ERP management system for enterprises, human chain management and other resources and data, Or as an application guarantee between different indivials and groups, etc

rationalization of the instry: after a period of boom, the instry began to develop in a more rational and correct direction, and the hype boom cooled down, which is concive to the development of the instry
the state is also strengthening its support for the application and development of blockchain technology.

Bamboo shoots in the mountains have a sharp mouth, thick skin and hollow abdomen. This is a true portrayal of Wang Fuzhong. Wang Fuzhong is a bamboo shoot in the mountains. He is not only empty and has no connotation, but also doesn't know how to pretend to understand. He makes some remarks about destroying the Three Outlooks everywhere. As a university professor, what he said is not convincing but abusive. He humiliated the army, the peasants and the people of Hebei Province. As a well-known man, he challenged the bottom line of social morality again and again. He does not have a university professor, or even a person's basic moral quality. His absurd remarks all day long are useless except to show his ignorance. He really doesn't know what he wants

As an economist, Wang Fuzhong should understand the pulling effect of agricultural development on China's economy. China is originally a big agricultural country, the development of agriculture has made many contributions to China's economic development since ancient times

6. What's wrong with the watch? How to maintain a watch? These are the problems often encountered by people who often wear watches
1. Why do watches suddenly go fast? At some point, we will find that the watch has gone dozens of minutes or even hours faster. What is the reason for this? There may be two reasons:
1. The watch is placed next to the electrical appliance or permanent magnet with magnetic field
there are foreign bodies in the hairspring
2. The error of wearing a watch is different from that of not wearing it. Why
this is the reason for hairpins. You need to go to a professional store for degaussing or cleaning, protecting and recuperating
3. Why didn't you buy a watch for a few days when the dry battery was dead
this is mainly e to the fact that the dry battery has been put into the watch when it leaves the factory, and the power consumption has started since then. When you buy it, it happens that it has been a long time since it left the factory. In this case, most manufacturers replace the battery for free
4. The quartz watch doesn't go away soon after changing the battery
this is generally caused by the quality of the dry battery, so try to replace the original dry battery when replacing the dry battery. If it is true that the dry battery changed in a professional store is still in such a state of affairs, it will be confirmed that the mechanical part of the watch has grease, or the gear shaft is worn, which shows that the starting working voltage and power consumption are too large, resulting in the rection of the service life of the dry battery. Therefore, in addition to the easy dry battery, we also need to take care of the watch regularly
5. Why do some quartz watches stop running innocently? There are several end swims that can cause stoppage:
① the watch has been in contact with the magnetic field. Because the micro thruster that pushes the pointer in the quartz watch is driven by magnetic energy, that is, the stepping motor, it is easy to be disturbed by the magnetic field, and it will stop or show the speed deviation. The quartz surface is inaccurate, most of which are caused by magnetic force
② the dry battery is dead
6. What if the watch is flooded
if the water is not serious, but there is a layer of fog in the glass, then wrap the watch tightly with several layers of toilet paper or absorbent flannel, and bake it at 15cm away from the 40W light bulb for about 30 minutes to eliminate the water vapor. Do not bake the watch directly near the fire, so as not to deform the watch when heated. It can also be worn on the wrist with the watch cover facing inside and the bottom shell facing out, and the moisture can be eliminated after two hours. If the water is serious, it's better to send it to the meter shop to wipe oil immediately to remove the moisture of the movement, so as to avoid parts rusting
7. The clock has errors. How to rece the errors
to rece the error, first of all, the temperature of the place where the clock is placed must be appropriate, not too high or too low. Secondly, the clock should not move or move as little as possible, but also avoid large vibration. When you have to move, you should also handle it with care. Third, the timing of the wind on the foot.

9. First of all, it is necessary to understand that when the power of the watch is sufficient, the watch will not go, or it will stop for a while and then start to walk. For example, if you take it with you all day, put it aside when you sleep at night, and wake up the next morning to find that it's a few hours slow, or even doesn't walk, then this is a typical watch stop and go phenomenon
let's introce the causes and solutions of the mechanical watch's stop and walk and steal stop.

first, the watch stops swinging.
as anyone who knows something about the mechanical watch knows, the full-automatic mechanical watch completely relies on the swing of the arm to complete the winding. Therefore, when the watch is not worn for a long time, or the daily arm activity does not meet the requirements of the watch winding, it will lead to insufficient winding potential energy, which will lead to the instability of the watch walking time or the situation of walking and stopping when the watch is not worn at night. The solution is that when we place the watch without wearing it, we first do arc movement, or use the manual winding function to winding the watch, so as to keep the watch with enough kinetic energy to maintain the power of the next day<

Second, watch bumps
in the process of wearing a watch, because most of the time is exposed, it is inevitable that there will be bumps. If you accidentally bump or fall on the watch in daily life, it may lead to the movement gear and other parts of the watch loose, dislocation and other situations. In serious cases, it will also lead to the mechanical watch eavesdropping. The solution is to take it to the repair shop for maintenance, so we should pay attention to avoid fierce collision and movement when we wear it everyday< Third, the problem of hairspring is also one of the reasons for the mechanical watch to stop and eavesdrop. It has been mentioned before that insufficient activity will lead to watch stop and go. Another situation is that if the activity is too large, the winding will become tight for a long time and cause the winding mechanism failure. It can also cause a lack of motivation. Generally, this kind of stop and go will happen from 9:00 to 12:00 in the evening. At this time, the clock hand of the watch with calendar function drives the calendar wheel, which directly leads to the lack of power and calendar jam.

10. The main reasons for the slow movement of mechanical watch are: insufficient activity and kinetic energy; The watch is magnetized; The movement oil sludge is dry
watches are more sophisticated, and there are more small parts, so they can work normally only when they fit each other,
