the main reason is that the value of bitcoin is artificially manipulated, so it has high risk and high profit, and it is easy to rise and fall sharply. That's why men's income changes so much of course, ordinary people certainly don't dare to speculate in bitcoin at will. After all, it needs a lot of money to support, which can make you rich overnight and ruin your fortune. Therefore, speculators need to have good psychological quality
in addition, the value of bitcoin often changes, and there is no law to speak of. It is mainly controlled by professionals with rich capital therefore, for ordinary investors, it's better not to put all their wealth into bitcoin. After all, the water in this instry is too deep, and you will lose all if you are not careful. Therefore, those opportunistic things or less to do, down-to-earth work to make money is the most important, after all, not everyone can become Buffett< br />

How do you define gambling? If it's legal, investing in bitcoin is not a gamble. Investing in bitcoin is as legal as investing in stocks and futures, and the price of bitcoin is no longer as crazy as it was a few years ago. Just pay attention to the risk when speculating

How to improve students' computing ability
once the exam is over, students will always complain: Alas, it's a calculation error again! Before explaining the test paper, the teacher will say: if the calculation is not careless, we can get better results. It can be seen that calculation has become a hindrance to the progress of many students' mathematics learning. Therefore, the improvement of computing power is imminent. So how to improve students' computing ability
first, cultivate students' interest in computing
simple calculation is often boring and students are easily bored. Therefore, according to the psychological characteristics of the lower grade students who are active and competitive, we can use a variety of training forms to replace the previous single form of practice. For example: training with games, competitions, etc; Driving trains, rushing to answer questions, breaking through barriers, etc. Various forms of training, not only stimulate students' interest in learning, but also make every student actively participate, so as to get twice the result with half the effort. Senior students can explain the principle of problem-solving more, let students understand the context of problem-solving ideas, know the reasons for this problem-solving, deepen the understanding, will improve interest< Second, pay attention to the training of oral arithmetic
oral calculation is the basis of written calculation, which requires not only accuracy but also speed. The formation of oral arithmetic skills and the improvement of speed can not be achieved by one or two days of training, but by constant training. In my opinion, the effect of mental arithmetic three minutes before class is very good. Before each class, prepare ten oral arithmetic questions for students to rush to answer, or let students write in a small book, check the answers in a unified way, make a summary every other time, and praise and reward the excellent students. The enthusiasm of students has been improved, and at the same time, they will pay attention to the correct rate. Of course, remember some common values, such as 2 π、 three π、 four π……， 112, 122, 132... And so on, which have a very good effect on speeding up the speed and accuracy of oral calculation< Third, strengthen the training of estimation
many problems in daily life don't need very accurate results, so we can use estimation to solve them. In this way, the speed is accelerated, and it does not affect the actual operation. When encountering such problems, let the students estimate as much as possible. In addition, even in the calculation of accurate results, the estimation will also play a monitoring role. Every time we finish a question, we can use the method of estimation to verify its correctness< 4. Pay attention to quick calculation and skillful calculation. Quick calculation and skillful calculation, that is, we usually say simple operation, the correct use of simple methods, on the one hand, can improve the speed of problem solving, on the other hand, can also make problem solving simple, improve students' self-confidence. The teacher can teach some basic laws first, let the students answer the questions, in the example of some calculation problems, let the students find the appropriate simple method. This requires students to have a clear grasp of the basic law of operation, especially the scope of its application. For example, multiplication has distributive law, but division does not. This requires students to divide by a number into its reciprocal, in the use of distribution law for calculation< 5. Develop good habits
we know that most of the time, students do not know how to calculate, but they wrong numbers, recite wrong multiplication formulas, or make mistakes in decimal points. These are tiny mistakes, but they often occur. Therefore, the usual practice should be strict, so that students develop a good habit of calculation. The first is to train students to be serious, meticulous, neat and standard. After careful calculation, we must emphasize checking calculation. There are many checking methods, such as checking step by step; It uses addition to check subtraction, multiplication to check division; Put it into the original question to check whether it is in line with the reality; It can also be checked by the above-mentioned estimation. Regular error correction training can also rece students' careless errors to a certain extent. Display the mistakes you are prone to make one by one, and compare them with your own reality. If you have them, you can correct them. If you don't have them, you will make fewer mistakes next time
in a word, computing teaching is a long-term and complex teaching process, and improving students' computing ability is not a matter overnight. Although the above points are not comprehensive, I believe that as long as we can seriously implement the above points, it will play a certain role in improving our computing power.
