People of what faith can't play bitcoin
bitcoin is a fraud, so we must be cautious in investment and financial management
even if it is called "hard currency", the price of gold will not only rise but not fall. There is no bubble in gold, but the price is too high, there is a bubble, and the bubble will eventually burst, such as virtual currency such as bitcoin. The more general virtual currencies, the closer bitcoin's value is to zero
this kind of currency, which is a purely calculated digital symbol, has no asset support, no financial revenue and expenditure, no cash reserve and no use value. It is only a circulation symbol. Once it loses its credit guarantee, it is a pile of beautiful printed waste paper. Investors should be alert that there is no so-called safe investment in this world, and all investments are risky
the people's Bank of China and other departments issued a document to severely punish the above-mentioned behaviors, making it clear that token trading is not protected by law. With some virtual currency trading platforms turning to overseas, speculative money speculation has also turned to "underground". In the face of continuous renovation, on the basis of continuous strict supervision, government departments should constantly upgrade the means and ability of supervision, and continue to increase publicity and crackdown on popular science, so as to avoid the masses being deceived
extended information:
investing in virtual currency is more of a kind of speculation. Investors should strengthen their risk prevention awareness and identification ability. Without confirming the identity of the other party, they should not be involved in money transactions, trust low-risk and high return investment procts, especially not join the investment and financing group without verification, These are often well-designed traps by telecommunication network fraudsters
it's better to purchase the investment and financial management accompanied by the children, and learn from the official and authoritative channels, and report to the police in time when they are found to be cheated. Properly protect all kinds of account password, identity information, etc., don't tell others easily. Any reference to the need for transfer and remittance should arouse high vigilance and consult with trusted acquaintances

bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
bitcoin is very similar to cash
the advantages of bitcoin are: no freezing, no tracking, no taxes, and extremely low transaction costs. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
bitcoin, Ethereum, bitcash, EOS, REBO, etc. are the mainstream digital currencies, which can be properly invested. All transactions are risky, so be cautious. You can search online for fire coin, coin security, OK, dobby trading platform, etc
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.
for the sake of wealth, businessmen, programmers and civil servants have all joined bitcoin crazily. Over the years, the price of bitcoin has gone through ups and downs. Some of them are already rich, while others end up in dismay among the earliest players of bitcoin in China, there is a legendary life of getting rich overnight, as well as a tragic story of family destruction. These stories bear witness to the development history of the coin circle
in fact, in my opinion, for bitcoin, the first batch may get up early and catch up late. Why do you say that< because over the years, people who can hold bitcoin are full of faith. Most of them came into contact with each other in the past 13 years. They were sold when the price rose to more than 7000, or got off ahead of time, or plummeted after the price rose. Now it's too late. The person who holds bitcoin for a long time is the one who forgets the private key of the wallet, which means that this part of the coin is lost and will never be taken back
Why do you want to go up? What's the logic
not to mention how many years after the excavation, no one should have g this thing for a long time
take your time
is bitcoin a currency? No, money needs to be liquid, so it needs to be actively over issued to eliminate inflation. Bitcoin can't, so it's not money. It's just because money can't rise so much. Have you ever heard that money can ride a roller coaster? There is no such thing
at best, it can only be collectibles, such as gold, silver, jewelry, ancient books, calligraphy and paintings. You can accept them if you like, and sell them for money if you don't want them
so why is this thing going up so crazy now? In fact, it's just hype
you need to analyze the mentality of the holder, except those who really have faith, the rest are not waiting for it to give you money. Do you want money or bitcoin? Of course, it's money, or I won't ask if it will go up
everyone is bidding up its value. It's a tacit thing to get money after shipping. When you don't ship, you only have a market value, not money. So in essence, you have to ship. After shipping, you can "pursue a better life"
will bitcoin keep rising? This actually doesn't exist, you don't sell bitcoin? You don't know? Don't you want a better life? You will meet your real needs more or less by discounting when you are still young and energetic. The money I earn is for use, and bitcoin does not create value. Then the money I want to use is yours. It's so simple. To put it bluntly, the longer the time, the greater the desire for discounting, even at a stable high level, This kind of pressure still exists. With this pressure, the rise will be limited, and the decline is the manifestation of pressure accumulation
here we need to introce something that we haven't mentioned before, which is the circulation disk. In fact, the proportion of bitcoin circulation disk is not high. Why such a large market value of things can rise and fall more quickly is actually the problem of circulation disk. That is to say, only a small part of the circulation disk is supported by money, and most of the non circulation is actually false value
you can now switch back to the topic
when the total amount of something that can be hyped is exhausted, that is to say, you have lost the way to obtain it at no cost or low cost. Then you have to hold it through trading, and it is not a necessity of your life, and you do not have to hold it. Maybe the price is already at a high level, and the rise and fall of the market will not be very crazy, If you want a big return, you have to buy a large amount of money. The cost you hold is very large. The cost means that the risk is high, and ordinary people can't afford to play. Please note that the original purpose of money is to fight small for big. How much investment enthusiasm is there at this time
because it has completely presented its own value, that is, the so-called generation currency, and obviously it has not achieved the expected goal, such as the idea of decentralization, which is impossible to realize. If it is realized, you will not care how much it is worth, whether it will rise or not, but only how much you hold, and its value logic will collapse
at this time, we can see whether it has collection value. It is no longer proced, but it is a pity that it is not a complete collection. It has neither scarcity nor the most basic aesthetic feeling. It has no artistry, craftsmanship and so on. Its quantity is very large. Do you think degradable garbage bags have collection value? Even if this kind of garbage bag is no longer proced, it is still not
to sum up, 1. There is no cheap way to get it; 2. The price is already very high, the profit space is small, and the cost is high; 3. The value logic has collapsed, and it is not a token; 4. Even as a collection, it doesn't mean much. What are these rules destroying? It is confidence
do you still want to hold such a thing? It's normal that there are things to hold, things to come out and things to go in. But as I said before, there is a time pressure there. Money has to be used. Holding needs to be discounted
at this time, we have to talk about the circulation market. If the circulation market is not big enough, it is a dead hole. Theoretically speaking, if the value logic can not be realized, we should sell as a normal investor. We consider that most of the circulation market are normal investors, so it is inevitable that the sales volume of circulation market is larger than the purchase volume, As long as the money coming out is greater than the money going in, it can be seen that the market value is falling, and it is obvious that the shrinkage of the market value is several times of the actual outflow, because those that are not in circulation are nominal prices, and those that do not exist will disappear as soon as they fall
and this decline is continuous, if it worsens into panic selling, it will be irreversible
that's my point of view. Of course, I don't think it's possible to wait until the last coin is g out. At present, there are obvious signs of a decline in investment confidence. If you are a rational investor, whether you will hold bitcoin for a long time, most of the answers are whether or not you will buy on the cheap, and most of the answers are wait-and-see, which shows the problem, At the end of the day, bitcoin is about confidence
