1. The price of BTC and eth you see on this platform is not the real price against the US dollar, but the price in usdt, which is priced in OTC legal currency. Their ups and downs are all calculated in terms of usdt. All three of them are virtual currencies, just currency transactions, not real dollar prices

2. Usdt is a complete domestic counterfeit currency, formerly known as realcoin, but it has just changed its name. Realcoin is the second generation of domestic counterfeit currency, and the first generation is called chncoin Chinese currency. Both of them collapsed successively in 2013 and 2014

3. The actual value of usdt can be said to be equal to 0. Teda Company, which issued usdt, stopped providing any services to American citizens, that is to say, Teda Company could not provide usdt to us dollar

The impact of the okex incident on the currency market is fading; With the US election becoming increasingly white hot, the difficulty and hash rate of bitcoin are higher than before

in terms of price, so far, BTC has rushed to around us $11720, with a 24-hour increase of more than 2%

so the question is: where will bitcoin go in the next week

here are five factors that may affect the BTC price trend in the coming week

No.1 US macro level: election and stimulus plan this week, the US is the absolute focus of the macro market. The US presidential election will soon usher in a decisive moment (November 3)

analysts warn that if the Democratic Party (Biden) wins, the dollar will depreciate - and the long-term outlook for the dollar is already precarious. Goldman Sachs said last week that Trump's re-election was not enough to get the dollar out of danger

however, no matter what the election result is, professionals recommend buying gold as a hedge. However, in the view of others, bitcoin may bring more profits

However, e to the inverse correlation between BTC / USD and the dollar currency index (DXY), the strength of the US dollar, in the view of some bitcoin traders, will still affect the price trend of bitcoin. Although this correlation has become less and less obvious in recent weeks, the sudden weakness of the US dollar is still likely to be a boon for bitcoin

at the same time, not only the election, but also what happened before is also a topic of interest. Specifically, a coronavirus stimulus plan was in place before polling day

If this happens, trillions of dollars of liquidity will increase the growing debt pile of the United States, and Americans will see additional benefits, such as an additional $1200 economic stimulus plan

No.2 Europe suggests more intervention

with the outbreak again, the European Central Bank (ECB) is considering further measures

European Central Bank President Christina; In an interview with Le Monde on Monday, Lagarde said the European Central Bank would use more financial instruments if necessary

the European Central Bank's coronavirus stimulus program has purchased a total of 1.5 trillion euros of assets

"We haven't run out of options in our toolbox yet," says Lagarde

brexit is increasingly moving towards "no agreement" brexit, which makes the possibility of instability worse

No.3 the fundamentals of bitcoin have reached a new high

recently, bitcoin has maintained a strong resilience in the face of various black swan events. Influenced by okex, BTC recently dropped below $11200, but recovered steadily soon. So far, it has exceeded $11600

and on the technical level, the fundamentals of bitcoin also maintained a record strength this month

two days ago, the difficulty of the latest adjustment increased by 3.5% than expected

at the same time, the hash rate also climbed to a record high on Monday. At the time of publication, the estimated computing power for mining is 146 exahashs (EH / s) per second

as often reported in the media, the popular theory is that the price follows the hash rate, because the long-term investment prospect of bitcoin is better than ever before

No.4 analysts focus on $12000 BTC price breakthrough

for famous analyst Micha & # 235; For Lvan de Poppe, the key price conversion of bitcoin is becoming more and more reasonable

in his latest video update on Sunday, he stressed that the significant resistance level of weekly closing price below US $12000 for several consecutive years will soon end

Van de Popper believes that since the beginning of the bear market in early 2018, US $12000 has become the rejection point of the weekly chart, but the consolidation below cannot last forever

he concluded: "we are likely to rebound to the range of US $16000 to US $17000, because this is the obvious level and the last obstacle for bitcoin to begin to break through the all-time high."

after this move, there will be another consolidation period, which may last longer than the current period

van der BOPP added that he advised viewers to work hard to accumulate bitcoin, even in the $16000 range

No.5 market sentiment: greed is back

with the graal strengthening of prices, investor sentiment is also changing: data shows that investor sentiment is becoming more and more greedy. In the latest market data, the fear and greed index has returned to the "greedy" area, rising slightly from "neutral" in the past week

this indicates that bitcoin investors' emotional expectations will be bullish, but it should be noted that if the price rises too fast, "greed" will become "extreme greed", in which case the index is more likely to callback

If you fall in a pit, maybe you don't pay attention to it. If you fall in the same pit twice or three times, you are careless. Now network anti fraud is rolling broadcast, repeatedly remind the public not to be cheated, but still someone sent it. And it's giving money to cheaters over and over again

today, when we talk about the micro trading investment on the Internet, we all know that it's a fraud, right? The swindler said that by scanning the QR code with wechat on his mobile phone, he can register and then participate in the trading of stocks, foreign exchange, commodity futures, etc. You can buy one or two. The revenue is more than 90%

in fact, this simple and easy transaction is similar to gambling, and it is also a new means of Telecom fraud. CCTV "focus interview" has played a similar fraud. Making false investment platform in the name of investment. Recently, the public security cracked several such fraud gangs

the salesmen, regardless of their beauty or ugliness, use beautiful or handsome faces to add friends through various channels every day to chat, find out the amount of money and cultivate feelings. Then get to the point

when the victims think that they have made good friends or confidants, some of them have developed into girlfriends and girlfriends. Then let it be and recommend investment software. It claims that the emerging micro trading is also making money with it

easy to learn, easy to operate, buy up and buy down can make money. Entice the victim to download, install and register her personal account, and then guide her to operate. If the amount of money is less than 100 yuan, it won't waste too much time. It will let him play by himself. Xiaoqian is familiar with the software, and graally likes this investment. The more he invests, the more he invests

for those with large amount of funds, special personnel will be assigned to guide the operation, or teachers will be packaged to guide the operation, or makers, and teachers in the live broadcasting room, etc. Let you add money to invest again and again. As long as you enter this circle, you will not retreat completely

of course, most of the people who come in to play lose. After losing, they will want to stop playing. At this time, the teacher with better packaging will continue to bring them. If not, they will add your friends to another person. After cultivating their feelings, they will tell you that she has lost more

after having a common topic, he will tell you that the platform with you is not good, the instructor is not good, and so on. I'll operate with other teachers and earn back what I lost before. Then I'll buy it with you or accept it from teachers. If you lose so much, you can make more. As long as you can put money again, you will be fooled into a daze, thinking that losing money is just bad luck

the suspect captured by the police, as long as his client lost his investment, he made money. The police said: "behind this investment is wind control management. The account number of the administrator can modify the data in the background, and whoever wins or loses is controlled by them. The overall probability of winning and losing is also decided by them. The customer's business is 100% loss. "

fraud means, let a person be deceived once, may also repeat the same mistake, add money again and again

6. You are in the new area. If you want to raise the level of mining to level 6, you have to stick to it, and you can only dig in Erhai Lake. When you reach level 4, you can go to Yannan, Cangshan and Yanbei. When the mine is small, because there are many people digging, the refresh is slow, there is no way.

8. The cultivation of computational ability is an important task in primary school mathematics teaching. The level of a person's computing ability is the embodiment of his thinking agility and thinking flexibility in computing, which reflects the level of his basic mathematical quality. The level of computing ability not only affects students' academic performance, but also directly affects students' intellectual development, and also has a direct impact on students' future study and work. In the primary school stage, the main purpose is to cultivate students' ability to calculate integers, decimals and fractions, and to achieve correct and rapid calculation. At the same time, the method is required to be reasonable and flexible. How to cultivate and improve students' computing ability to meet the above requirements
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
