Why digital currency fell sharply yesterday

1. greedy!

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

3. 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

5. 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 + +
