Double computing power
when compared with other virtual currencies, bitcoin always mentions "21 million fixed output". In the early years, bitcoin had not been exposed to investors in a large area. It proced a lot and g a lot, but there was no demand. But now purchase bitcoin, the price is expensive, the output is small, the demand is big
we believe that when there is an imbalance between supply and demand, the price of goods will be affected. Influenced by the policy, many bitcoin holders are now keeping a wait-and-see attitude. The decrease of bitcoin in circulation in the market and the increasing demand for bitcoin in the market are bound to push the price up, but in fact, it will not be the investment speculators who come into the market at this high level who will benefit in the end
popularization of regional chain
the report released by professional institutions mentioned the problem of regional chain technology. The report shows that by 2027, the global investment value of regional chain technology will reach 300 billion to 400 billion US dollars. And the regional chain as an infrastructure development, will be applied to more and more scenarios
at that time, whether the popularity of regional chain will raise the price of bitcoin is also full of uncertainty
investor confidence remains unchanged
although many institutions and financial giants are short of bitcoin, investors are still confident in the future value of bitcoin. After all, in history, is there any trading proct that can soar 7.54 million times in eight years
professional agency analysts said that 10 years ago, the impact of the financial crisis had so far failed to get rid of the shadow of many countries, and the share price bubble continued to expand. Investors would worry whether the original financial system would collapse again. Bitcoin, which has a strong performance, will attract more investors with capital inflows, thus driving up prices. In a way, bitcoin is already a safe haven
although the trading of bitcoin was suspended by China in September 2017, bitcoin surged by more than 233% after de Sinicization< In November 2017, bitcoin began to hard bifurcate, that is to say, dividing the regional chain into two, which is equivalent to doubling the issue of bitcoin, which means that the value of bitcoin will be diluted. Affected by the impending start of hard bifurcations, bitcoin started on November 9, 2017 and has been in a state of decline for four days
the suspension of the 2x fork originally scheled for November 16, 2017 has eased the anxiety of the whole bitcoin instry chain over capacity expansion, and the market is a little relieved of the possible collapse crisis caused by the fork
bubble greater risk
many investors have seen the bitcoin appreciation and profit margins after they have entered the bitcoin trading market. However, the current domestic large-scale bitcoin trading platform has been completely closed, and the regulatory level has not relaxed the entry of bitcoin into the domestic market
bitcoin, as a speculative commodity, has great bubbles and unknown risks. We tend to ignore the risk, and it is often the risk that damages the funds in our pockets. When participating in a high-risk market, we must reasonably allocate personal assets, such as the allocation of stable financial procts such as stable profit selection investment plan. We must not use all our wealth to allocate high-risk investment procts
in a word, bitcoin has risen dramatically in recent years. It's hard to avoid some words like "you are the richest man in China now if you bought bitcoin eight years ago". But eight years ago, you didn't know that bitcoin could be as brilliant as it is today. You might as well change your vision and look for the next "bitcoin"
the above is the reason why bitcoin's price rises. As much profit as possible, there is as much risk. Although bitcoin has been rising in price, no one is sure in the future. If we must invest in digital currency, we must first control its risks.

[March 1] today, Xiaopeng announced that, considering the impact of the epidemic, some users have a long period of offline car viewing and ordering decision-making. Therefore, the "Xiaopeng P7 intention money doubling plan", which was originally scheled to end on February 29, will be extended to March 15, ring which the rights and interests of users participating in the activities will remain unchanged, bringing more convenience to users who love this ultra long enrance intelligent car race. During the event, users can not only get a maximum discount of 20000 yuan by paying Xiaopeng P7 deposit, but also win rich rights and interests such as Xiaopeng auto app mall points, electricity subsidies, priority delivery and mysterious gifts.
the plan of doubling deposit can enjoy a maximum of 20000 yuan in cash.
before March 15, users can double the car payment by paying Xiaopeng P7 deposit. The premium for this event is divided into four levels: 5000 yuan, 10000 yuan, 15000 yuan and 20000 yuan. If the user pays 20000 yuan, 40000 yuan can be dected, which is equivalent to enjoying 20000 yuan preferential benefits. In addition, after successfully paying the intention money, users can forward the sharing link to invite friends to make an appointment for the test drive of Xiaopeng P7. If they successfully invite 10 or more friends to make an appointment for the first test drive, they will get the points of Xiaopeng auto app5000 mall; If the invited friends participate in the intention money doubling plan through the sharing link, both the invited and the invited new and old users can get additional points of Xiaopeng auto app8000 mall
users who have already reserved Xiaopeng P7 before the event can enjoy the benefits of the scheme of doubling the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of the amount of. Among them, the users who have paid the intention money of 2000 yuan before the activity can continue to enjoy the power value-added rights and interests; Users who have paid 99 yuan before the event will receive 50 km (10 kwh) of electricity every day from the date of payment (inclusive) until the vehicle is delivered. In addition, users who participate in the event can also enjoy the priority of delivery rights and receive mysterious gifts at the time of vehicle delivery
Since the pre-sale of Guangzhou auto show in 2019, Xiaopeng P7 has released a total of 3 models and 8 major versions, with a pre-sale price range of 240000-370000 yuan. Users can make reservations through Xiaopeng automobile official website, APP, WeChat official account, Tmall shopping mall, offline sales center and other channels. p>

According to the report, at around 9:30 yesterday, the price of bitfinex bitcoin was as high as $2310, equivalent to about 15922 yuan; The price of bitcoin on fire coin network also broke through the integer level of 15000 yuan, with the highest approaching 16000 yuan. So far, the domestic bitcoin price has doubled again, with an increase of 115% in the past 30 days
It is worth noting that after this round of rise, the number of domestic investors has increased, but the trading volume is still much lower than before. According to some data, the global share of RMB bitcoin trading rose from less than 10% to 11.9%, ranking only thirdfirst, to strengthen the understanding and perception of calculation theory
to make students know how to calculate, that is, to strengthen the mastery of rules and calculation theory "Curriculum standard" points out: "in teaching, we should further cultivate students' sense of number and enhance their understanding of the meaning of operation by solving problems." Therefore, in the teaching, we should combine with the practical problems to understand the calculation theory and guide students to master the calculation method. If the students understand the calculation theory, and the teacher consciously guides the students to strengthen the understanding of the calculation theory, then the students will naturally master the calculation theory, and it is easy to make the use of the calculation theory to become a conscious action. Although rote learning can be effective in the short term, or a large number of mechanical imitation will also have a rapid effect, in the long run, only when students understand the calculation theory can they really accept the calculation method itself, and even if they forget the calculation method itself, they may also dece the calculation method again by recalling the materials provided by the teacher in the classroom. It is also an important way to develop students' learning ability to explore calculation theory.
secondly, it is a highlight of mathematics curriculum reform and a difficulty in practice to advocate algorithm diversification. Algorithm diversification encourages students to think independently, to think diversely and to solve problems indivially. In the process of encouraging algorithm diversification, students' thinking is fully activated, and new and flexible methods are constantly popping out of students' minds. Different ideas collide here, and everyone enjoys the fun of successfully solving problems, which is very helpful to tap students' potential and cultivate students' interest in learning mathematics. More importantly, students have the opportunity to choose the most suitable algorithm according to the actual situation, which is also the requirement of respecting students' personalized learning. For example, the fifth grade students learn the method of finding the least common multiple. The enumeration method is very basic and easy for students to understand and accept, but it's really slow. If students find that in many exercises of finding the least common multiple of two numbers, they constantly double the large number, they can also get the least common multiple. This method is not only simple and easy to use, And it's easy for students to understand. Therefore, it is necessary to encourage students to think and exchange diversified calculation methods for the same topic and optimize them< Third, we should pay attention to the variety and interest of practice forms, and enhance the effectiveness of practice.
the strength and weakness of students' computing ability directly affect the improvement of students' other aspects of mathematical ability. Although we oppose excessive practice, practice makes perfect. The cultivation of computing ability cannot do without appropriate practice, and any knowledge needs to be graally accepted and internalized in the process of using. We can make efforts in the diversity and interest of practice forms, improve the operability of practice, combine learning with doing, and integrate teaching, learning and doing; Enhance the game, challenge and interest of practice, and combine learning with fun. Let diversified exercises attract students' active participation, and change the former "ask me to practice" to the present "I like to practice"; Turn the practice into the exploration of skills and small games; In addition, the students' group listening, checking, competition, self-made and taking turns to write questions are all good forms of practice. In this way, by giving full play to the autonomy of students, to consolidate the computing skills, students' computing skills will be improved unconsciously
to achieve this goal, it is undoubtedly a severe challenge for teachers to prepare lessons. It requires our teachers to carefully design exercises according to the specific teaching content and training objectives, truly proceed from the reality of students, fully consider the psychological needs of students, respect the cognitive rules of students, and make classroom exercises truly hierarchical and interesting, so as to achieve the purpose of enhancing effectiveness< (4) guide students to understand some quick calculation skills and find some calculation rules.
although we object to teachers' blindly passing some calculation skills on to students, it is necessary for students to properly understand some calculation skills. Everything will have potential rules, people will always consciously or unconsciously ponder some of the skills, students are no exception. For example, in four operations, if students memorize some common data, find 4 when they see 25, and find 8 when they see 125, they can better master the skills of calculation, which is helpful for students to achieve the requirements of "correct, rapid, reasonable and flexible"< 5. Cultivating students' good habits is an important guarantee for the formation of computing ability. It is the main way and measure to prevent calculation error and improve calculation level to see operation symbols clearly and form good study habits
1. Cultivate students' habit of serious examination. See the operation symbol clearly, see the number clearly, make clear the operation order. For example: 12 as 21, 2 as 5, 3 as 8, etc
2. Cultivate the habit of serious calculation. In the four operations, it is necessary to train students' calm and calm learning attitude. When encountering the calculation questions with large numbers and many steps, we should not be impatient, think calmly and calculate carefully. Even simple calculation problems should be careful. Don't act rashly. When calculating, the writing should be neat, the format should be standard and the method should be reasonable
3. Cultivate students' habit of patient examination. It is impossible to ask students to be 100% correct in calculation. Therefore, in teaching, we should also ecate students to form a good habit of carefully checking the calculus after calculation, and take the test as an indispensable part of the calculation problem. The inspection should be patient and careful, and check step by step: check whether the numbers and budget symbols are copied wrong. 2. Check whether the calculation process and results are correct. At the same time, we should combine the teaching content to teach students appropriate checking methods, such as re algorithm, inverse algorithm, exchange addend, multiplier and other checking methods
improving students' computing ability is a permanent theme in mathematics teaching. As a primary school mathematics teacher, we should start from the long-term development of students and strengthen the cultivation of students' computing ability. Starting from each class, we should train strictly and scientifically. Over time, students' computing ability will graally increase.
in addition to the hardware requirements, the actual performance is also related to the operating system and the software itself. For example, whether the software is optimized for multiprocessors, etc. If the system or software itself only supports single task and single thread, then no performance improvement can be achieved on servers with al, four or more processors.
