1. THP (turbo high performance). It is a new cryptocurrency based on proof of capacity (hereinafter referred to as POC). Its main feature is to use hard disk as a consensus participant, rece the consumption of power resources by cryptocurrency, lower the threshold of participation, make its proction mode more decentralized, and more secure and reliable, so that everyone can participate in the mining of cryptocurrency, and generate credit and value through mathematical algorithm and distributed mining
pow (proof of workload): the pow mechanism relies on machine computing power to perform mathematical operations to obtain digital currency. Whoever has high computing power can proce more digital currency. To get rich through labor, more workers will get more (BTC is the mechanism of pow mining)< But there are fatal shortcomings:
1. The cost of mining machinery and equipment is expensive (ranging from tens of thousands to hundreds of thousands), and the depreciation rate of equipment is high
2. The equipment costs a lot of electricity (high cost)
3, not really centralization (if you are rich enough, you buy lots of mines, your computing power is large, when the amount of computation is greater than 50%, the whole network has the final say that it will cause autocracy).

the bitcoin market is an extremely crazy market. Some people have become billionaires overnight, while others have been cut leeks. The ups and downs, joys and sorrows of the world are incisively and vividly interpreted anyone who knows about the bitcoin market should know that before, the value of bitcoin was only 1000 yuan, but it rose to 17000 yuan in 2017. With such an appreciation rate, the profits matched with it are also amazing. Bitcoin appeared in 2009. At that time, the value of bitcoin was only US $0.1. Looking at the price in 2017, there is a big difference between the two. If someone had a lot of bitcoin when it first came out, he would be one of the richest now
When the engineer became a billionaire, he began to travel around the world. In fact, he has long had the idea of traveling around the world, but e to economic reasons, it has not been realized. Now, the engineer can live freely and realize his dream of traveling around the world. In an interview with reporters, the engineer also said, although his original job is very good and can provide him with stable income, he has always dreamed of the global world and visiting friends from various countries. Now, he is living the life he wants, and by selling bitcoin, he has got hundreds of millions of assets, which is enough for him to spend his whole life3.
Those people are living a good life now. In the early days, these "tuyere pigs" who played bitcoin earned a lot of money
I. Nakamoto found bitcoin, and now it is fading out of the bitcoin circle
4. To tell you the truth, bitcoin has gone up so fast that what it held a few years ago now makes money. Can go to the big trading platform to see the market, recommend to coin an, simple operation.
5. To be honest, bitcoin is a good thing, the key is whether the regulatory and economic system is suitable for its development. Whether the country's economic network soil is suitable for its development. In China, business operators pay too much attention to speculation and short-term earnings, too much attention to the existence of speculative currency, and the real economic assets can not match the development of virtual economic assets such as bitcoin, which is the key.
6. Calculation ability is the basis of mathematics. To solve mathematical problems, we must first pass the calculation, and pay attention to the calculation. I am Mr. Wang, focusing on primary school mathematics, sharing problem-solving strategies, promoting interesting mathematics, providing family counseling suggestions, welcome your attention. Computing power is not innate. Basic algorithms are graally acquired after primary school. It takes a lot of time to master the four basic operations of addition, subtraction, multiplication and division. Only after the students establish the real number concept system can they carry out the abstract addition and subtraction symbolic operation. The level of operation ability is reflected in the accuracy, speed and flexibility of operation. The following detailed explanation, for your reference<
to cultivate mathematical computing ability
first of all, it should be clear that the learning of mathematical computing content is a systematic and continuous system. Taking the calculation content of primary school as an example, the learning sequence is as follows:
① the number concept system
the calculation of number is basically deepened with the expansion of number field. From the addition and subtraction method within 20 in grade one to the addition and subtraction method within 10 000 in grade three, the larger number in grade four, integer concept has been basically formed and accompanied by the emergence of decimal concept system, The fifth grade is the key stage of the development of the concept of fraction
from integer to decimal to fraction constitutes the cognitive process of primary school students' number concept development, including the size of number, the comparison of number, cardinal number and ordinal number, odd number and even number, digit number, the combination and decomposition of number, which are the preparation for calculation learning<
② the accuracy and speed of operation
learning sequence determines that each stage of computational learning is very important, which is the foundation of the next stage, and consolidating the foundation is the necessary condition for improving the mathematical computing ability. First of all, the operation must be correct, which is the premise, which requires various kinds of operation practice. The third grade must take ensuring 100% accuracy rate of calculation as the practice goal. Only when the accuracy rate of calculation develops, can we further improve the speed. If the basic oral calculation reaches a perceptual formula, we can get the answer immediately
the higher the grade is, the smaller the proportion of basic computing in cognitive resources is. Computing is a kind of program. Only by turning computing into mathematical facts and extracting them at any time can we put more cognitive resources on more complex problems
there is no shortcut, only diligent practice<
③ flexibility of calculation
don't learn some skills training projects of single integer operation. The flexibility of calculation is reflected in children's enlightenment and application of calculation theory. For example, the first grade's method of rounding up ten is the Enlightenment of rounding up the idea of first calculation. If you don't experience the rules and calculation theory, you can't refine the mathematical thought
the higher the grade is, the more flexible the calculation is. To understand and flexibly use the law of simple calculation is actually a thinking process to reasonably deal with the calculation, so that the calculation can achieve a fast and flexible state. The fourth grade is the key stage of quick calculation and skillful calculation of integers. For example, Mr. Wang's fourth grade extracurricular mathematics knowledge of the calculation section
only by contacting with different types of questions, can we make all kinds of skillful thinking and methods to integrate, and the flexibility of calculation is the key to reflect the level of mathematical calculation ability.

8. 1、 The main structure of the financial situation analysis report
(1) the title of the report
is the most concise summary of the financial situation analysis report. It should not only accurately reflect the theme of the analysis report, but also be concise and eye-catching. As the contents of financial analysis report are different, there is no uniform standard and fixed model for its title, which should be determined according to the specific analysis content. Such as "analysis report of a month's brief accounting statements", "comprehensive financial analysis report of a year", "analysis report of asset utilization efficiency", etc
(2) basic information
that is to summarize the comprehensive situation of the enterprise, so that the users of the financial report can have a general understanding of the analysis and explanation of the financial situation. For example, the main business scope and other business situation of the enterprise, and the operation and financial status of the enterprise are introced. This part requires proper words and accurate data reference. Absolute number, comparative number and composite index number can be used to explain economic indicators. Special attention should be paid to the current operation focus of the enterprise, and important matters should be reflected separately< Comprehensive analysis
(3) comprehensive analysis
comprehensive analysis is to analyze and study the business situation of an enterprise, analyze the problems while explaining the problems, and find out the causes and crux of the problems, so as to achieve the purpose of solving the problems. Financial analysis must be reasonable and well founded. It is necessary to refine and decompose various indicators. It is necessary to be good at using tables and diagrams to highlight the content of analysis. When analyzing problems, we must be good at grasping the current key points, and reflect the focus of enterprise management and problems that are easy to ignore< (4) overall evaluation after financial explanation and analysis, we should give fair and objective evaluation and prediction on the operation, financial status and profit performance from the financial point of view. The evaluation should be carried out from both positive and negative aspects. The evaluation can be carried out separately, or the evaluation content can be interspersed in the explanation part and the analysis part< (5) work suggestions: the opinions and opinions formed by financial personnel after analyzing the operation and investment decisions, especially the improvement suggestions for the problems existing in the operation process. It is worth noting that the suggestions in the financial analysis report should not be too abstract, but should be specific and practical< (1) analysis of business indicators
mainly describes the basic situation of the enterprise, the completion of the main economic indicators of the enterprise's proction and operation business in the current period, such as the actual output, business volume, sales volume and year-on-year increase and decrease. The financial evaluation indexes reflecting the development ability of enterprises are: sales growth rate, capital accumulation rate, total assets growth rate, three-year average capital growth rate; The average growth rate of sales in three years. Comparing these indicators with the standard indicators and the same period of last year, the increase and decrease values are calculated, and the achievements and existing problems in proction and operation are analyzed from the following aspects: first, the impact of changes in the operating environment, mainly the impact of changes in the internal and external conditions of enterprise proction and operation; Second, the adjustment and influence of business scope; Third, the impact of other business situations and matters to be disclosed. Find out the main influencing factors, and explain the main reasons for the achievements of the enterprise, explain the reasons for the problems and difficulties in the operation of the enterprise, so as to make the enterprise clear the direction of development in the future< (2) analysis of profit and loss index
1. Compare the actual profit of the current period reflected in the income statement with the planned amount and the actual amount of the same period of last year, and analyze the profit realization and the increase and decrease value. What is the total realized profit (loss) in the current period, the increase or decrease amount and the increase or decrease rate compared with the plan and the same period last year; This paper analyzes the composition of the actual total profit in the current period, including the main business profit, other business profit, non operating revenue and expenditure, and the increase and decrease of the planned amount and the same period of last year
2. Calculate the profitability analysis indicators such as return on net assets, return on total assets, main operating profit margin, cost profit margin, and calculate the increase and decrease value with the standard value compared with the same period of last year
3. According to the analysis and calculation results, analyze and evaluate the strength of the enterprise's profitability, and analyze its impact on the current profit from the year-on-year increase and decrease of main business income, the year-on-year increase and decrease of cost and expense, other business profits, net operating income and expenditure, and find out the reasons for the enhancement (weakening) of profitability< (3) analysis of capital index
1. Through the analysis of capital structure proportion, this paper analyzes the composition proportion of each item in the current balance sheet, income statement and other statements, compares the instry proportion with the project proportion in the same period of last year, and combines growth analysis with structure analysis to judge the rationality and scientificity of the composition proportion of each item
2. The evaluation indexes mainly include: total assets turnover, current assets turnover, fixed assets turnover, inventory turnover and accounts receivable turnover. For example, through the analysis of the turnover rate of accounts receivable, we can get the speed of the realization of accounts receivable and the level of management efficiency. If the turnover rate is high, it shows that the collection speed is fast, the account age is short, the asset liquidity is strong, the short-term solvency is strong, and the collection expenses and bad debt losses can be reced. At the same time, by comparing the turnover period of accounts receivable with the credit period of enterprises, we can also evaluate the credit degree of the entrusted processing units, adjust the original credit conditions, and formulate the corresponding collection policies (next to page 64) (next to page 62). By analyzing the turnover of fixed assets, we can know whether the utilization rate of fixed assets is reasonable and whether the structure of fixed assets is appropriate
3, calculate the solvency of the enterprise, the main indicators are: quick ratio, current ratio, asset liability ratio, equity ratio, etc
4. Variance analysis of indicator changes: compare the calculation results of various indicators in this period with the standard value and the same period of last year, find out the indicators with large or abnormal changes as the key analysis objects, and reveal the problems and reasons existing in the operation< The index to measure the value maintenance and appreciation of state-owned assets is the value-added rate of state-owned capital. Through the analysis of this index, we can fully reflect the protection of state-owned assets, timely and effectively find the phenomenon of erosion of state-owned assets, and reflect the preservation and growth of state-owned capital< It is generally believed that the higher the value preservation and appreciation rate of capital, the better the capital preservation of enterprises. When the rate of value preservation and appreciation reaches 100%, it means value preservation. When the rate exceeds 100%, it means value increment. If the rate is less than 100%, it means that the state-owned capital is devalued. It means that the state-owned assets have been eroded, lost and lost, and the capital preservation has not been realized
3. According to the degree of realization of the value maintenance and appreciation of state-owned capital, analyze the reasons, especially attach great importance to those who have not realized the value maintenance of capital, find out the loopholes and study the countermeasures.
