What is the digital currency released by IAC platform
there is no price limit for P.S. digital currency trading, so investment should be cautious!
Digital currency is a kind of legal tender, which must be issued by the central bank. Both digital gold coin and cryptocurrency belong to digital currency, which is not a network virtual currency, because it is not limited to virtual space, but is often used for real goods and services transactions, such as bitcoin, Wright coin, bitstock, etc. at present, there are thousands of digital currencies issued around the world
extended data:
1. Impact on financial infrastructure
the decentralized mechanism of value exchange based on distributed ledger technology has changed the basic settings of gross and net settlement on which financial market infrastructure depends. The use of distributed ledgers also poses challenges to trading, clearing and settlement, as it promotes the disintermediation of traditional service providers in different markets and infrastructures. These changes may have potential impacts on market infrastructure other than retail payment systems, such as large payment systems, securities settlement systems or trading databases
If digital currency and distributed ledger based technology are widely used, it will bring challenges to the intermediary role of financial system participants, especially banks. As a financial intermediary, banks perform the ties of acting supervisors and supervise borrowers on behalf of depositors. Usually, banks also carry out liquidity and maturity conversion business to realize the financing from depositors to borrowers. If digital currency and distributed ledger are widely used, any subsequent disintermediation may have an impact on savings or credit evaluation mechanisms1.
inertia: Newton's first law is also called the law of inertia.
inertia can be used to describe inertia. All objects have a kind of inertia. The manifestation of this inertia is that they are unwilling to change the original state of motion. As long as they are not affected by external forces, they will keep the original state of motion, unless they are forced to change the original state of motion by external forces<

inertia phenomenon:
the property of an object to keep its state of motion unchanged is called inertia, not force
inertia that any mass object has. That is, any object has the tendency to maintain the current state of motion. For example, a static object has static inertia. A moving object will keep moving without external force
inertial force is a virtual force introced for better analysis of problems, just like centrifugal force and centripetal force
I hope my answer can help you, ha ha
but first of all, whether the object hit by the football is forced or not depends not on whether the object is hit, but on the impact process. For example: when a football hits a wall and the wall doesn't "fly", is there no force on the wall
the football is in contact with (static) objects at a certain speed
because of inertia, football wants to move on; Because of inertia, the object wants to keep still; This is really an objective situation. But just knowing this can't explain why
because of the relative motion, the distance between them is getting closer and closer. When approaching to a certain extent, the latter hinders the movement of the former
(1) macroscopic view: on the contact surface, the object deforms and proces elastic force
the elastic force of the football on the object pushes the object forward: if the object, like a wall, is subjected to a large enough fixed force, then the two forces offset and the object does not move; If not, then the object may "fly" out
the elasticity of the object to the football hinders the progress of the football; The football may stop, it may bounce in another direction, depending on the angle and strength of the impact
(2) microscopic view: when the distance between two objects reaches the level of molecular distance, the repulsive force between molecules is generated. In fact, elasticity is the macroscopic expression of this molecular force
in a word, because of the special properties of some forces (elastic force or intermolecular force), when objects are close enough, this kind of force will naturally occur
here, inertia is only [helping to form the conditions for generating force], but it cannot be said that inertia generates force. For example, when an object is flying at the same speed as a football, the football will never hit the object, there will be no force between them, and their state will not change, but can you say that they have no inertia?
