BTC investor's family destroyed
With the improvement of people's living conditions, we all have some spare funds in our hands. Some people want to make some investment through these funds and get rich returns. However, we all know that investment is risky after all, so some people will definitely have some losses. This time, a couple in Dalian directly lost 20 million yuan e to their investment in bitcoin. After the loss of such a large amount of property, they couldn't think of it for a moment. They wanted to escape the current problem by committing suicide, and killed their three-year-old daughter before committing suicide{ RRRRR}
How do I view this incident
first of all, I want to tell you that investment is risky. If you don't have complete assurance in your daily life, or are not very keen on investment, you must keep your cash. After all, people are having a hard time now. You have some cash in your hand, and you can deal with it when you encounter problems. The main reason why this tragedy happened to the couple was that they believed that bitcoin would rise sharply, so they put all their wealth into it, which has played a very good warning effect for us
there are many unsuccessful currencies in history, such as the Deutschmark in the Weimar Republic and, more recently, the Zimbabwean dollar. Although previous currency failures were usually e to over inflation that could not happen on bitcoin, there were always potential technical errors, currency competition and political problems. The basic lesson is that no currency can be considered absolutely safe from failure or difficult times. Bitcoin has been proven reliable for several years since its birth, and it has great potential to continue to grow. But no one can predict the future of bitcoin< The rapid rise in price of BR />
does not constitute a bubble. Artificial overestimation will lead to a sudden downward revision, which will form a bubble. The price fluctuation of bitcoin caused by the indivial behavior of thousands of market participants is the result of the market determining the price. From the emotional point of view, the reasons for price changes include: the loss of confidence in bitcoin, the huge difference between price and value not based on the fundamentals of bitcoin economy, more and more news reports stimulating speculative demand, fear of uncertainty, and outdated irrational prosperity and greed.
According to the data of okcoin, a well-known digital asset trading platform in China, yesterday (June 14), most of the trading hours of the currency price showed a narrow consolidation operation. The amplitude was less than 4% from the opening to 20 o'clock in the evening, and then there was a big drop, reaching the lowest of 18136 at the close. As of today's press release, currency price inertia fell to the lowest 17425 line, the latest trading at 17800
According to analysts of okcoin bank, the daily line level, yesterday's daily line closed the spindle line with short upper and lower shadow lines, and the 5-day moving average crossed the 10 day moving average to form a high dead cross. The trading volume continued to shrink and the trend of this level weakened; At the 4-hour level, the moving average system (5, 10, 20) formed a downward divergent pattern of short positions after being glued, and MACD index continued to operate in the weak area below the zero axis; 1 hour level, short trend is also good, temporarily deviated from the bottom of the volume and price, short-term rebound or finishing demandto sum up, the current major cycles, including the daily line, have entered the short-term operation pattern, and the probability of effective stop fall reversal is very small, so don't rush into the market to buy the bottom. In view of the current market, we can only take short-term strategy and intervene in batches at important (important) support levels. Focus on the support range of 15600-16000 within the day. If the price stops falling in this area, you can build a position to intervene. The upper pressure focuses on the platform low of 17800, and rebounds to this position. The nearby area will leave and wait. Personal suggestions, for reference only

Yes , at about 4:00 on June 18, 2020, Zheng Yiwei cut his daughter's neck with a sharp knife on the bed of the bedroom in the middle and south of his home in a community in Shahekou District, causing his daughter to die of massive bleeding. After wrapping his daughter's body, he came to the No. 18 pier of Xinghaiwan bridge and threw her body down the bridge. Later, Zheng and his wife Wang committed suicide by jumping into the sea. Zheng attempted to commit suicide. At about 10:00 on June 18, he took the initiative to account for the fact of the crime in the second hospital of the University of medicine
Zheng said that after graating from University, he has been engaged in freelancing "playing finance". Bitcoin is his main investment project, making a lot of money and worth tens of millions
however, the huge fluctuation of bitcoin has brought a disaster to Zheng Yiwei. By the beginning of June this year, he had lost more than 20 million yuan e to using capital leverage to participate in speculation“ The money includes four million from my parents and 500000 from my father-in-law and mother-in-law. The rest is my savings and money borrowed from my relatives over the years. " Zheng said
once the hard-working family property was lost, it also owed a large amount of debt to close relatives and friends. Zheng Dawei is going to commit suicide< he said that at first he only intended to die by himself, but later his wife tried to persuade him, but to no avail, and the couple decided to "go together"
faced with the public prosecutor's question, Zheng explained that because of the idea of "want a family together", the couple decided to kill their own daughter first, and then commit suicide by jumping into the sea together. On June 17, he bought sleeping pills at the pharmacy and fed them to his daughter by his wife. Zheng said that before killing his daughter, he had "no heart and hesitated" and first stabbed the plush toy beside the child with a knife
at the end of the trial, the defendant Zheng said that he confessed to the crime of killing his daughter, and said that his wife's suicide was also caused by himself, hoping that the court could give him a heavier sentence
{rrrrrrr}
extended data
bitcoin continues to rise sharply. Analysts warn that we need to be careful about the sharp correction in the future:
Tom Demark, a well-known digital currency analyst, said that bitcoin has a total of 9430 points from the high on June 26, 2019 to the low on March 16, 2020. If we add 9430 points to the level on June 26, 2019, Then, it is expected that the price of bitcoin will rise to 23288, which is the current trading range in the market
although bitcoin is expected to recover soon, Demark also admits that if investors continue to pour in, bitcoin may continue its earnings and ignore the signal that the current trend is running out
Matt Maley, chief market strategist of Miller Tabak asset management company, pointed out that since 2016, bitcoin has fallen 20% or more for 10 times, 30% or more for 7 times, and 48% or more for 4 times. Therefore, investors should not underestimate the volatility of bitcoin
I think we should pay attention to where the money comes from and through which channels it is hyped. In fact, it is necessary to find out. In fact, bitcoin has a great impact on the society, because the price of bitcoin has been very high and deviated from the actual value, So ordinary people in the process of speculation bitcoin, we must see clearly the current social situation
First, the price of bitcoin is too highin fact, most people already know that the price of bitcoin is too high, because in about 10 years, the price of bitcoin has increased by tens of thousands of times, which is impossible for any asset, because the investment procts of Putong can only increase by about 10 times in 10 years, You can imagine how overvalued bitcoin is{ RRRRR}
in the society, the speculation of bitcoin has a great impact on the real economy, because a lot of money has flowed into bitcoin, and there are very few pre class resources in the real economy, so it must be a very big blow to the development of the real economy in the future. I think the country must solve this situation well, Only when more funds are channeled into the real economy can more wealth be created. The real economy is the field that our country must pay attention to in the future development and the foundation of our country
virtual currency does have a certain value, but its own economic risk is very high, so it is not recommended as a key investment object
in fact, it's not just this couple that has happened to virtual currency. In the early years, bitcoin became one of the most important virtual currencies in the dark network because of its good concealment, because bitcoin is a kind of currency that can't be traced and traced. At the earliest time, bitcoin could not only be used for some dirty transactions, Buying pizza, buying games and even buying a bottle of mineral water can be paid with bitcoin, which can be said to be a universal currency{ RRRRR}
therefore, investment has risks, so we must choose the investment target and direction carefully. The exchange rate and value of virtual currency are too erratic, and we can't know if there is someone behind it. We should develop a rational financial mind, accumulate wealth reasonably, and don't become the leek of others
in this paper, I would like to talk about some superficial understanding of this problem< First, we should fully understand the importance of developing computing ability
one of the aims of primary school mathematics teaching is to cultivate students' computational ability, and teachers must have enough understanding. Some teachers don't pay enough attention to the cultivation and improvement of students' computing ability, and they don't let students find the rules and interests of computing. This is a big obstacle to cultivate and improve students' computing ability, which must be removed. Computational ability is a necessary ability for students< Number and calculation are widely used in daily life, work and study. In the real world, from the perspective of mathematics, there are mainly three aspects: number, quantity and shape. However, measurement is inseparable from number and calculation, and the quantification of body size is inseparable from number and calculation. Therefore, number and calculation are the most basic tools for people to understand the objective world and the basic knowledge and skills that every citizen should master< Number and calculation are the basis for students to learn other mathematical knowledge and even other subjects. This part of the knowledge is not good, students can not enter the normal learning< Number and calculation play an important role in cultivating students' thinking ability. Mastering the process of number and calculation is also the process of cultivating students' abstract generalization ability. In this way, students also develop the ability of abstract generalization in the process of learning to master the knowledge of number and calculation
4. The teaching of number and calculation is concive to infiltrating the enlightenment ecation of dialectical materialism. The concept of number is graally formed and developed with the needs of human life and practice. When teachers want to teach the concept of number, the relationship between calculation method and calculation method, they can infiltrate the enlightenment ecation of dialectical materialism
Second, clarify the calculation theory and improve the teaching quality of calculation
in the teaching of calculation, teachers should pay attention to explain the principle of calculation and reveal the law of calculation, so that students can know what it is and why it is
1. The abstraction of arithmetic is a difficult point in primary school teaching. In teaching, we try to transform the abstraction into the concrete by means of visual demonstration, so as to make the arithmetic clear
2. Learn to operate with tools, explore and comprehend. Psychologists believe that thinking begins with action. To enable students to master mathematical knowledge and promote the development of thinking, it is necessary to build a bridge between image thinking and mathematical abstraction, and give full play to the role of learning tools. For example, if the students have difficulty in understanding the "method of making up ten" in addition within 20, we will ask them to come out with sticks to help them learn the calculation method of "making up ten" by playing with sticks
3. Contact with practice to deepen understanding. Using students' existing knowledge and experience to understand new knowledge is the main way to construct teaching knowledge structure. Properly using old knowledge in teaching, assimilating new knowledge through analogy, and realizing positive transfer of knowledge are concive to students' understanding of new knowledge and recognition of new knowledge structure. For example, when teaching the calculation method of decimal addition, we can use the rate relationship of RMB units that students are familiar with to explain the reason that decimal points must be aligned
4. Pay attention to perception and strengthen stimulation. For the parts that are easy to be ignored by students, we should pay attention to strengthen the stimulation intensity (such as emphasis on entering and leaving places, emphasis on the treatment of decimal points, etc.) to attract students' attention, leave students a clear and correct impression, and avoid and rece errors in future calculation
5. According to the characteristics that students are prone to illusion and thinking set, we should consciously differentiate and compare the similar concepts, rules and formulas, so as to promote the accurate differentiation of new and old knowledge
6. Practice in time to consolidate and improve. Carry out targeted exercises, strengthen the key points and difficulties in the calculation process, and strive to consolidate in class
7. Pay attention to feedback and correct in time. Timely feedback, find out the students' mistakes, help students analyze the reasons and correct the mistakes in time< Third, we should deal with the relationship between written and oral arithmetic
oral arithmetic is a kind of calculation method which can only calculate and get the results by thinking and language without any tools. It has the characteristics of fast and flexible
mental arithmetic is an important part of computing power. Oral calculation is the basis of written calculation and estimation. Both written calculation and estimation ability are developed on the basis of accurate and skilled oral calculation ability. Without a certain basis of oral calculation, the cultivation of written calculation and estimation ability becomes the water without source. In addition, mental arithmetic is widely used in daily life, proction and scientific research. Therefore, it is very important to insist on the training of oral arithmetic and listening arithmetic in teaching to improve students' computing ability
(1) oral arithmetic teaching must run through the whole process of primary school mathematics teaching. In the lower grades, basic oral arithmetic such as addition and subtraction within 20, multiplication within the table and division are arranged; The middle grade arranges some oral arithmetic which is the basis of written arithmetic and often used in daily life; In order to cultivate students' ability of using knowledge flexibly and their ability of oral calculation, senior students arrange some questions of using operation law to do oral calculation in exercises. Each teaching reference book puts forward the requirements for the oral arithmetic of this semester in stages. Teachers should make the cultivation of oral arithmetic ability to be implemented, and effectively improve students' oral arithmetic ability
(2) arrange oral calculation reasonably. In compulsory textbooks, the basic oral arithmetic, which is the basis of written arithmetic, is taught before written arithmetic, while some difficult but not the most basic ones are taught after written arithmetic, so as to further improve students' oral arithmetic ability. For example, addition and subtraction within 20 is an important foundation of addition and subtraction, and only oral arithmetic is taught. In addition and subtraction within 100, two digit addition, subtraction of one digit and integral tens, such as 27 + 6, 27 + 30, are the basis of both written and oral arithmetic. Therefore, this part of the content before the written calculation, only teaching oral calculation; It is more difficult for students to master double-digit plus or minus double-digit, so the first grade first teaches written arithmetic, and the second grade further requires oral arithmetic. In this way, students can not only learn written arithmetic, but also form a strong ability of oral arithmetic
(3) pay attention to the teaching of oral arithmetic. Oral examples should pay attention to the intuitive demonstration and operation to make students understand the calculation theory
(4) teach students oral arithmetic and develop their thinking. In order to improve students' ability of oral arithmetic, we should teach students correct methods of oral arithmetic. The methods are various, and we should guide students to choose the methods that they can easily understand and master. Never guide students to do oral arithmetic with the method of written arithmetic. Two digit addition: 28 + 37. I find that some students think like this: 8 + 7 = 15, indivial digit is 5, ten digit is 2 + 3 + 1 = 6, ten digit is 6. This is completely the idea of written calculation. In fact, you should think like this: 28 + 30 = 58, 58 + 7 = 75. You don't need to have a vertical pattern in your head
practice has proved that strengthening the training of oral arithmetic can not only improve the calculation level of students, but also develop their thinking ability< Fourth, encourage students to use simple algorithms to improve their ability and develop their thinking
simple calculation is a practical and effective method to improve students' calculation speed. Simple calculation often uses certain operation laws, such as addition calculation often uses addition exchange law, addition combination law, and multiplication exchange law, multiplication combination law, multiplication distribution law, etc. in multiplication calculation, some calculations are simplified from complex to easy. The study of simple calculation can not only improve the students' calculation speed, rece the calculation errors, but also help the development of students' thinking. Therefore, in the teaching process, teachers should strengthen the teaching of simple methods
in addition, let students remember some common data, which can simplify the calculation process and improve the calculation speed. I remember an ecator said that a person's memory before the age of 13 is the best. He can remember a lot of things at this stage. Although he doesn't know why and how, these things don't affect his memory. The unknown reasons of these knowledge will be solved with the growth of his age and the increase of his knowledge. Therefore, we should pay attention to the development of students' memory, especially before the age of 13. The content of calculation in middle and high grades is extensive, comprehensive and comprehensive. Some common operations are often encountered in real life. These operations have no specific rules of oral arithmetic, and must be solved by strengthening memory training. The main contents of my intensive training are as follows: 1) the square result of each number from 1 to 10 in the natural number; ② A method of oral calculation for the square result of two digit number of 5 on a digit; ③ Some specific calculation results, such as 125 × 8＝1000，25 × 4 = 100, 0.25 =, 0.75 =, 0.125 =, 0.375 =, 0.625 = etc. These special calculation results are frequently used in practice, homework and life. If we master and remember them skillfully, we can transform them into abilities, which play a good role in calculation and proce high efficiency< 5. Pay attention to cultivate the good habit of careful examination and calculation
the teaching of calculation also needs to train students to form the habit of careful examination and examination. Don't just shout "be careful!" to students, To teach methods, strict requirements, form habits, improve the accuracy of calculation
the new curriculum standard points out that we should pay attention to the cultivation of students' habit of inspection. Inspection is a good way, it can make people find their own mistakes in time and correct them in time. In the process of teaching, teachers should pay attention to strengthen the teaching of checking calculation, let students use different methods to test a problem, master the test method, and skillfully use this method to judge the correctness of the answers to similar problems
six relations between addition, subtraction, multiplication and division are often used in checking. The estimation is often based on the variation of proct and quotient. For example: according to the multiplier & gt; 1, proct & gt; Multiplicand (except 0); Multiplier = 1, proct = multiplicand; If the multiplier is less than 1, the proct is less than the multiplicand (except 0), you can judge which of the following questions is greater than the multiplicand, which is less than the multiplicand, and which is equal to the multiplicand: 8 × 、 nine × 、 one × 2、0.9 × 16、5 × 1、3 × 、 × 1 According to divisor > 1, quotient < divisor (except 0); Divisor = 1, quotient = dividend; If the divisor is less than 1, the quotient is greater than the divisor (except 0), it can be judged without calculation ÷ 14、8 ÷ 1 、21 ÷ 、 ÷ 7、2 ÷ 1、0.45 ÷ Is the quotient greater than the divisor, less than the divisor, or equal to the divisor< Sixth, enrich learning activities, be happy with teaching and learning, and stimulate students' interest
the calculation problem is composed of numbers and abstract operation symbols, which makes students easily feel irritable and tired. Therefore, teachers should
Burst position means that some people go up and some people go down. Although we can't describe bitcoin as a zero sum game , many people do suffer serious losses
for those small partners who recognize bitcoin, they very much recognize the value of bitcoin and believe that bitcoin will continue to rise in the next few decades
for those who deny bitcoin, they think bitcoin has no value, it is just a bubble of capital. I personally prefer the latter view. p>
bitcoin has more than 110000 people in one day
this news is absolutely a sensation in other instries, but in the bitcoin circle, it is a very normal phenomenon that more than 110000 people burst their positions. We know that bitcoin's big ups and downs are very common. Now bitcoin has broken through $60000, reaching the highest level ever. During this period, 110000 people will burst their positions at the same time on the same day. We can imagine how many people will lose money{ RRRRR}
First of all, in my opinion, this problem is actually equivalent to a pseudo proposition. After the collapse of bitcoin, nearly 40 billion of funds did suffer losses. However, we know that bitcoin itself is the same as the stock market. Even if there is a decline, there will also be a surge. Therefore, this is only a short-term market fluctuation. But we can't look at bitcoin from the perspective of stocks. After all, bitcoin has fallen to the bottom before. Today, I'd like to discuss with you what losses bitcoin will cause to investors{ RRRRR}
Third, how to treat the investment of bitcoin
I have a suggestion under all the answers about bitcoin, that is, if you are an ordinary family, do not invest in bitcoin, because bitcoin itself is like stocks, but it does not conform to the objective economic laws of our market. Its scarcity, privacy and free mobility are not valuable in themselves
