Digital currency plummets

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. greedy!

3. Yesterday, gold plummeted to the highest point of 1.5%. Although it rose in the London market, it fell at least 0.75%.

4. Don't add any more money. So far, no country has issued digital currency. Swindlers have issued a lot of worthless digital currency. They can also trade on the exchange opened by swindlers, buy RMB and lose money. They can make a lot of money by buying the currency issued by these swindlers. They repeatedly emphasize how much money they can make a year and what is the rate of return, But never mention how these profit returns come from? There are many leeks who are blinded by profits!

5. 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!

6. 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.

7. 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.

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 + +
