4. Different people have different opinions on this issue! A lot of people and the media questioned it. But there are still a lot of people playing. The yield of this kind of currency may be relatively high, but it is unreliable. It is suggested to invest in digital currencies such as bitcoin, Ruitai coin and Qianjin card.

5. It's very strange that you ask this question. Why does no one care? Atomic currency is given to users free of charge in China through app registration, playing atomic games, advertising and so on. People have said that China and the United States do not sell it. What's the problem with no sale transaction? Moreover, atomic currency issuers are from foreign countries.

6. Dog money has been out for several years. The value of digital money lies in the number of people it participates in and the volume of transactions, as well as the liquidity in the entity. The real decentralization of digital money also determines that its price is determined by the market and players! I also bought this one, so I can communicate with you

PSTN (public switched telephone network)

is a global voice communication circuit switched network, including commercial and government-owned

includes commercial and government-owned. It also refers to simple old fashioned telephone service (POTS). It is a collection of all circuit switched telephone networks since Alexander Graham Bell invented the telephone. Today, in addition to the final connection between the user and the local switchboard, the PSTN has been fully digitized technically

extended data:

the main components of PSTN network are as follows:

1. Transmission system: cable (cable, optical fiber) is the main, cable and wireless (satellite, ground and radio) are used alternately, and the transmission system transits from PDH to SDH and DWDM

2. Switching system: the switching equipment in the telephone office, the exchange, has been programmed and digitized graally, and the connection process is controlled by computer

User system: including telephone, fax and other terminals, and a pair of wires used to connect them with the switch (called user loop). The user terminal has been graally digitized, multimedia and intelligent, and the user loop has been digitized and broadband

Signaling system: in order to realize the communication between users, various control signals are provided between exchange offices, which are mainly call establishment and release

access through PSTN:

dial up Internet / Intranet / LAN- Network interconnection between two or more LANs

Although PSTN has some problems in data transmission, it is still an irreplaceable networking medium (Technology). In particular, the application of xDSL technology and procts invented by Bellcore, which is based on PSTN, expands the development and application space of PSTN, making the networking speed between 9mbps and 52mbps

8. My friend, first of all, you can find out what is virtual currency and what is digital currency!

9. Real encrypted digital currency, I don't know who gave it the title. In many places, bitcoin is illegal
