2021 computing power war time
bitcoin bulls often mention that the scarcity value of this cryptocurrency is the main reason for its continued rise. Bitcoin is similar to gold to some extent. The growth of its supply is extremely slow, and it is still slowing down. Its total supply will only reach 21 million
with the increasing interest of institutional investors and retail investors in bitcoin, global exchanges such as the Chicago Board of options (CBOE) have launched bitcoin futures contracts. This is likely to encourage more institutional investors to invest in bitcoin, while at the same time further curbing the price volatility of bitcoin
this much anticipated bitcoin futures trading has been launched on the Chicago Board of options exchange, which represents a significant step in the legalization of cryptocurrency. Futures is a derivative / financial instrument, which can force dealers to buy and sell an asset at a specific time and price
December is a few days away, and we are looking forward to 2021. Due to the special situation this year, many auto brands may not launch procts according to the original plan, so next year may be the "outbreak year" for the launch of heavy new cars. Next, let's make a list of the heavyweight new cars that are expected to be launched and delivered next year to see which one you are most optimistic about
On September 24, 2020, Gaohe hiphix, the first proct of China express, was officially launched in Beijing and is expected to be graally delivered in the first half of 2021. There are 2 models of this model, which provide 6 seat / 4 seat seats. According to the official introction, hiphix is designed and developed with the concept of "Scene defined design, software defined car, and co creation defined value", aiming to create a luxury SUV that meets the needs of Chinese high-end consumers. Since the news of the new car, the doors of hiphix have always been the focus of attention. Its six doors, whether open or closed, have a very hard core sense of technology. It is understood that Gaohe hiphix is equipped with the Notouch (hereinafter referred to as NT) winggate system independently developed by Chinese express
entering the car, the 12.3-inch full LCD instrument panel and 14.9-inch suspended central control screen are very bright, the number of traditional physical buttons has been reced by about 50%, and the IX will become the first BMW model equipped with 5g communication technology
in terms of power, BMW IX will be equipped with BMW's fifth generation Edrive electric drive system, with front and rear al motors. The maximum comprehensive power is 370kW, the acceleration time of 0-100km / h may be less than 5 seconds, and the wltp range will exceed 600km
summary: judging from the above new cars, the new energy vehicle market in 2021 is still very exciting, so which one are you most looking forward to and optimistic about? Welcome to the comments section to share your views

first, the improvement of the ability of calculation requires the study of hard theories and rules.
the correct operation must be based on a thorough understanding of calculation theory. The calculation theory in students' mind is clear and the rules are firmly remembered. When doing four calculation problems, it can be carried out in an orderly way. There are two mistakes in integer multiplication, 25 times 3 equals 95, 24 times 5 equals 100, which typically reflects that students do not have a thorough understanding of multiplication theory in the process of learning arithmetic, and how to deal with the number of multiplication carry is relatively vague. Furthermore, divisor is a decimal division in the two wrong cases (1). 44 divided by 1. 8 equals 8, 11. 2 divided by 0.05 equal to 22.4) also shows that the students' understanding of the law is not deep enough
to understand the meaning of the order and operation law, the operation order refers to the operation of the same level from left to right. In the formula without brackets, if there are addition, subtraction, multiplication and division, multiplication and division should be calculated first, then addition and subtraction; If you have brackets, you should first count the ones in the brackets, and then count the ones in the brackets. Primary school textbooks mainly talk about the law of exchange and combination of addition, and a property of subtraction: "subtracting the sum of two numbers from a number is equal to subtracting two addends from the number in turn." And the commutative law, associative law and distributive law of multiplication. These laws are applicable to the operation of integers, decimals and fractions at the same time, and are widely used. In the two wrong examples [327 - (27 + 75) = 375, 87 times 2 divided by 87 times 2 = 1], both show the students' wrong understanding of the calculation law and the operation law< Second, the improvement of computing power needs to pass, understand and master basic knowledge. In order to get the calculation results, students should first consider what mathematical concepts, operation laws, operation properties, operation rules and calculation formulas to use. Therefore, fully understanding and mastering these basic knowledge determines whether they have the ability of calculation. For example, if students want to have the ability to calculate four items of scores, they must first understand the meaning and nature of scores, understand and master the basic knowledge and corresponding basic skills such as general score, approximate score, the interaction between score and false score. Only when the relevant basic knowledge is explained clearly and the students really master it, the students will not make mistakes in calculation. Compared with the lower grades, the basic knowledge of the higher grades is more abundant. Therefore, we must not rush for success in teaching. We should help students start from sorting out the basic knowledge they have learned, use the transfer, and continue to deepen. For example, when teaching the addition of fractions with different denominators, first ask the students to answer the meaning of addition, and they will know that it is the operation of combining two numbers (or more numbers) into one number. Next, let the students observe and find that the fractions with different denominators and the units of fractions are different, and they can't add directly. After understanding this, they can guide the students to use the knowledge of general division to "turn differences into similarities", So the problem is transformed into the addition of fractions with the same denominator< Third, the improvement of calculation ability needs excellent oral calculation ability.
the new curriculum standard points out: "the basic and developmental nature of mathematics should be highlighted in the compulsory ecation stage." As for the ability of oral calculation, it is the basis of learning mathematics, and the level of oral calculation ability has an extremely important impact on students' basic calculation ability; The training of oral arithmetic is helpful to cultivate students' keen observation; It is helpful to cultivate students' comprehensive thinking ability; It is helpful to cultivate students' quick reaction ability; It is helpful to the cultivation of students' innovative consciousness. How to train the ability of oral arithmetic is an important subject worthy of discussion and research. Teaching practice tells us that it is very necessary to train students' oral arithmetic ability, and we should pay enough attention to it< Fourth, the improvement of computing ability needs to cultivate students' good computing habits.
to improve students' computing ability, we must pay attention to the cultivation of good computing habits< Make students form the habit of proofreading carefully
2. Students are required to see each data and operation symbol clearly, determine the operation order, and choose a reasonable operation method
3. Make students form the habit of careful calculation and standardized writing. Students are required to write neatly, with correct format, correct handwriting, no scribble, no alteration, and keep their homework neat and beautiful< 4. Make students form the habit of estimation and self-conscious checking. Give them the method of checking calculation and estimation, and take checking calculation as an important part of the calculation process to carry out strict requirements, advocating the use of estimation to check the correctness of the answers
5. Make students form the habit of mutual inspection. When a problem has been initially calculated, it can't be calculated completely. It's inevitable for students to make some mistakes in calculation, which requires students to check carefully
6. Be good at drafting.
I think there is still a market for bitcoin mining, but from the era when ordinary computers can participate in bitcoin mining to today's mines, miners all over the world compete in computing power at the same time. With the increasing number of miners, the difficulty index of the game is getting higher and higher, and it depends on their strength to play it in the end. If you want to open a mine, then the basic costs include mining machinery, electricity, maintenance, labor, mine rental, etc., and the only source of income is to replace the bitcoin with legal currency. Mining machinery will be lost, bitcoin prices will fluctuate, and electricity charges will rise, all of which are uncontrollable If you have a deep understanding of the current bitcoin and pay enough tuition fees, you will understand the whole bitcoin profit system, and its water is still very deep. Apart from the current primary and secondary trading market, we turn our attention to the current computing power mining instry. First of all, we answer the question given in the question. If it is a large-scale bitcoin mining mine, even if the price of bitcoin falls too much in the short term, or even has fallen below the shutdown price, they will continue to mine
therefore, a certain price of bitcoin is lower than the mining cost, which has a great impact on small and medium-sized investors and the vast majority of retail investors, but has almost no impact on the mines with huge financial support. There is a market for mining, but retail investors and small and medium-sized investors are graally eliminated
1. Three pools in the moon:
this is a must for Hangzhou. There are lakes in the island and islands in the lake. But in my eyes, it's like a small park. There's nothing special about it. But it's on the West Lake after all. It's very rare. Those who haven't been there must go. There's no need for those who have been there
price: 20 yuan / person time: 16:00 end
2. West Lake cruise:
on the lake, you will see all kinds of boats, at this time you will be very confused. Which one is better? I strongly recommend that you take [the kind of artificial rowing], which can reach the moon in Santan. It's really hard to describe what it's like to shake the boat. I'm happy and relaxed! The boating master will also introce you to the beautiful Hangzhou. And it's more cost-effective than taking a big boat. The big boat is n people (about 60 people). Take a 15 minute stroll on the West Lake. It's 45 yuan per person. The boat can only sit six people at most. By the hour. 80 yuan / hour. This is a super hot one. I also think this is the best<
3. Huxinting:
on the West Lake, you will see three islands. One is Santan Yinyue, the other is not open to the outside world. It is said that there are ghosts in it. Another one is huxinting. The island is very small and few people go to it. I didn't go there, so I took some pictures. I think it's similar to the moon in Santan and the park. Hehe o (∩)_ ∩) O ~
price: 10 yuan / person time: unknown, it's just like closing at 16:00.
2. West Lake: Ten sceneries
1. Spring dawn of SUDI 2. Wind and lotus of Quyuan 3. Autumn moon of Pinghu 4. Broken bridge and resial snow 5. Willow waves and warblers 6. Watching fish in Huagang 7. Sunset of Leifeng 8. Cloud arrangement of two peaks 9. Evening clock of Nanping 10. Moon of Santan
look at these names, It's made me dizzy. I think you fainted, too. But don't worry, these scenic spots are all around the West Lake. If you want to walk, don't be tired to death, really. It takes three hours to walk without looking at the scenery. It is strongly recommended that you [cycle]. There are many [private] car rental centers in Hangzhou. The deposit is 200 yuan, 5 yuan per hour. It's a good deal. It's private! It's public. It's hard for us outsiders to use it. Only Hangzhou citizens can use it. The place I borrowed last time was in Bertie's. Because it's a private stall with a lot of swimming, I'm not sure you can find it this time. But there are a lot of private car rental sites. You should be able to find it. Scenic spots are not as beautiful as I expected. A little disappointed. I didn't even see the lotus in such a little place. Sobbing ~ ~ ~ (& gt_& lt;)~~~~
price: except Yuemiao (25 yuan / person) and Leifeng Pagoda (40 yuan / person), other attractions are free<
3. Music fountain
music fountain: located in Hubin Pedestrian Street (three parks), it is very romantic and more suitable for men and women in love. Take a look at the scenery. I feel like I can do idol drama. O(∩_ But there are so many people to watch. You must go early and grab the seats in the first few rows. Otherwise, nothing can be seen
time: 10:00, 13:00, ",", ",", ",", ",", "," (holidays will be added two) = Price: free
four, Hefangjie Street + snack
Hefangjie Street: the path is super invincible long, very very interesting, similar to Town God's Temple in Shanghai, Qibao old street. I highly recommend this place! The "leaders" of Hefang Street are all snack streets. I think it's a little expensive. It's 5 yuan for something that tastes bad. It's like sugar water. It's so sweet. But it's a tourist city after all. It's OK to think about it. 50 yuan can make you full. I'm a big eater. The taste there is not as good as that in Shanghai. But it's not bad. Give it a good one. I must eat it now. Everything I eat has been taken back to the hotel. It's cold. It's not delicious. But there are so many people, so crowded that it's hard to move. Please pay attention to safety. If you want to grab a seat! I'll wait, I'll wait, wait< 5. Lingyin feilaifeng: Lingyin Temple, feilaifeng: I'm not a superstitious person. Since I don't believe in Buddhism sincerely, I didn't go either. If you believe in Buddhism very much, you can go to worship. Different people have different opinions. My friend said for you that if you really worship Buddha, you will go for three years. Then your wish will come true. Otherwise... It's better not to join in the fun. I remember closing at 18:00. Similar to Yuemiao, Leifeng Pagoda (newly built) probably closed at this time. I haven't been to any scenic spots of temples. They say it's not easy for a little girl to go there. I think it's just burning incense, asking for autographs and paying homage to Buddha
price: 35 yuan / person (package ticket, 30 yuan if you go directly to Lingyin Temple)
Liuhe and Liuhe pagoda
Liuhe Pagoda: it's an ancient pagoda that has gone through 800 years of vicissitudes. So I chose Liuhe tower instead of Leifeng Tower. Leifeng Tower is a new one. I don't think it's very attractive. The Liuhe tower is different. It's really the vicissitudes of history. Watching the Qiantang River, people said it was magnificent. Maybe when I went there that day, the fog was too heavy, and I didn't see anything magnificent. I thought it was rough. But the feeling of landscape echo is really good. It's a bit of a return to nature and a sense of relaxation. The pressure's gone. This place is a little far from the center of the city
price: 30 yuan / person time: 18:30 clear tower
7. Songcheng
Songcheng: far away from the West Lake, I went to Hangzhou for two days and one night. Alas ~ ~ I really don't have time to see it. Next time I go to Hangzhou, I must go to Songcheng to play. It's said that there is a haunted house there. I'm going to be the boss there.. People there are all dressed up in ancient times. The price is a little expensive. It's 80 yuan per person. I have to charge for the performance, but I think it's worth it. You can get the goods according to the price. It's more fun to play in the evening. Let's take a look at the eternal love of song city. But if your hotel lives in the center of the city, then the taxi fare is very expensive ~<
eight and ten new sceneries
1. Yunqizhu path 2. Manlongguiyu 3. Hupaomengquan 4. Longjing tea 5. Jiuxi smoke tree 6. Wushan Tianfeng 7. Ruan Dunhuan bi8. Huanglong tucui 9. Yuhuang Feiyun 10. Baoshi Liuxia
these small places, I was cheated miserably. I broke my leg climbing the mountain. If you are a mountain climber, you must go. If it's the little princess, the little emperor. Don't pay for abuse. You're going to regret it. I went to Huanglong tucui: it's a nice name. The place there is much smaller than I thought. It didn't take long to enter. What? It's over. Oh, my mother. A fake tap is spitting water, that is, Huanglong spits green. Gem Liuxia is a mountain climbing. The scenery is also very common. I feel like I'm in the park. I want to roll down the mountain. There is a Yuelao temple in Huanglong cave, but there is a charge. There is a big word "fate" outside the gate of Huanglong cave. There are many people taking photos. It should be very famous. I know it's not fun to listen to the names of other scenic spots. It's "Longjing tea" or "old people". The prices of these scenic spots are not very expensive, with an average of 15 yuan per person< No.9: Xixi Wetland: I didn't go there. My colleagues didn't think it was fun when they went there. They asked some netizens and said it wasn't fun. But the boating master told us that it is rare to have such a large wetland in Hangzhou. I don't think I've been there. I must go. Although "if you are the one" is very beautiful, I think this advertisement probably cost a lot of money
price: 70 yuan / person
