Digital currency plummeted after the Spring Festival

1. There are several reasons for the collapse of digital currency:
1. Some unscrupulous media and we media spread false information
2. The domestic policy on digital currency is tightening, and the voice of supervision is endless
3. In recent years, countries such as Europe, America and Japan are not very friendly to digital currencies represented by bitcoin and wikilink
4. After a round of explosion, the value of digital currency instry graally returns to rationality.

2. Money is like this: when it is saturated, it will fall; when it is unsaturated, it will rise,

3. The mainstream digital currency can be used as a unit for transaction, but the digital currency will not! Air money is hard to say! The answer is not easy, please adopt it!

4. As of October, the total number of digital currencies has exceeded 2000. With the market downturn, mixed projects, competition between the fittest and the fittest, and capital graally calming down, the price of standard legal currency has been falling since the issuance of many currencies. However, many new types of currencies with value-added potential have emerged. Against the trend, Bob is one of them. At 16:00 (Singapore time) on October 19, Bob has opened up full withdrawal and trading on bikicoin exchange, opening up the trading pair of Bob / usdt, with a total issuance of 60 billion yuan and a total circulation of token? 15 billion.

5. The higher the reward, the greater the risk. The same is true for digital currency. If there is a rise, there will be a fall
(1) the long-term investment of digital currency is a kind of high-risk investment
digital currency investment is faced with policy uncertainty, technology risk, competition risk and other risks. For example, the policy changes of digital currency supervision in various countries, the possible cracking of consensus mechanism, and the risk of competition and substitution of other decentralization and legal digital currency. These risks determine that digital currency investment is still a high-risk investment in the long run
(2) there are many uncertain factors affecting the short-term investment of digital currency
in the short term, the price of digital currency is affected by more technical, news and fundamental factors that affect short-term supply and demand, and the price fluctuates greatly, with strong uncertainty and unpredictability.

6. It can't be simply attributed to the exchange. Sometimes there are sudden short-term fluctuations, and the exchange does participate. But the main topic is about the monthly time span, which is difficult for the exchange to control. It is more the result of the joint operation of hot money and large institutions. However, the sharp decline of the overall currency value can't be separated from the basic economic principle: the relationship between supply and demand, This is beyond anyone's control

8. How to say, there are many reasons for the sharp drop of digital currency in the past two days. All kinds of stock indexes, futures, gold and so on have fallen. I feel that if BTC is not affected by the new bad factors in the past two days, it will fall to about 7500. If the old fellow is going to enter the market these two days, it is OK to grasp a low point and approach. Of course, the current fundamentals are not very stable, and so on
in addition, it has nothing to do with whether you make money or not. Buying or not can make money in this wave. The question is whether you can have a correct prediction of the future. Whether there is enough psychological enrance and sufficient capital chain to deal with all the situations
finally, the risk of currency speculation is high, so we should be cautious when entering the market. It's just like losing money when the currency goes up. To be specific, it's troublesome. I can only say that only when the world economy goes up can virtual currency make money. If the world economy goes down, it can only make money if the virtual currency soars. What's more, when the world economy is not good, the bad factors are enough to make the virtual currency fall very seriously
I can't remember a sentence from Warren Buffett, which means that you should be afraid when others are greedy, and you should be greedy when others are afraid. Only in this way can you make money
I want to make money, but it's not easy to be scared. It's also not easy to live when you lose all your money. Encourage with you.

9. Objects are automatically destructed before they die. Malloc / free can not meet the requirements of dynamic objects. When creating an object, the function should be executed automatically, and the new corresponding delete should not be ignored. Therefore, C + + language needs an operator new which can complete the dynamic memory allocation and initialization< br />malloc/free; Free is a library function, not an operator. It is not under the control of the compiler, and the task of executing constructors and destructors cannot be imposed on malloc / free. They can be used to apply for dynamic memory and free memory, new. For objects of Non internal data type, malloc / delete alone must be used in pairs
malloc and free are the standard library functions of C + + and C language, and new and delete are the operators of C + +

Before and after the Spring Festival, the price of bitcoin changed the declining trend since the beginning of 2018, with an overall increase of 90%. On February 21, it once rose to $11720. At present, it maintains a consolidation position of about US $10000 and chooses a new direction

in the short term, the current situation is much more optimistic than the previous range of 6000-8000 US dollars. But investors still need to be cautious until the direction is set

However, it can be seen that the regulatory policies of cryptocurrency in various countries are becoming more cautious. Therefore, in the short term, the price of bitcoin should not have a very sharp drop
