First of all, we need to know what digital currency is. Digital currency is characterized by decentralized transaction currency. The most famous is bitcoin. However, digital currency has not been recognized by China in recent years. Recently, China plans to issue China's digital currency DCEP, or DC for short. Digital currency itself is currency. When you ask how to make money, you are actually asking, How does money make money? In fact, there are many channels. First, we will have funds in the later stage to conct private placement of digital currency. Second, how do we usually earn RMB? Now, when we promote the use of digital currency in China, we will use digital currency to earn money

as a digital currency, in fact, what China issues is similar to legal currency. The purpose of legal currency is to stabilize the RMB, which should float up and down 1:1 per second. According to different exchange rates, DCEP: usdt will float up and down 7:1. In the later stage, it may be 1:1 according to China's increasing competitiveness, which is also graally declining in recent years

as a digital currency, if you want to make money, there are many ways. Major exchanges can convert it into different digital currencies. Other digital currencies may not be as stable as usdt and DCEP, and the price will keep rising and falling according to the demand. At this time, we can buy and sell stocks in a similar way to earn the price difference, If you don't enjoy it, many digital currency exchanges provide contracts, which can buy and sell multiple times, or be bullish or bearish, or even hundreds of times at most. Many people get rich through this way, but there are also many people who lose their property. In addition, this kind of exchange will make your currency return to zero in a way, We should be wary of many such exchanges running away - refer to the second largest exchange checked OK exchange

in addition, as a national form of digital currency, there should be short positions. For example, China's state-owned enterprises carry out digital transformation to form community-based currency, which may be airdropped according to the DCEP they hold. This is my guess

in addition, defi's liquidity mining, commonly known as market making, is more popular now. In the later stage, it may replace the exchange. Everyone is an exchange and can charge a handling fee

This is a Linux system IP address configuration command. The specific meaning is:

set the IP address of the system to 192.168.0.2; The subnet mask is 24, that is 255.255.255.0; The broadcast address is 192.168.0.255; The name of NIC device is eth0

all computers in the network must set a unique IP address to communicate normally. Because of this unique address, users can select the objects they need from thousands of computers efficiently and conveniently when they operate on networked computers

The IP address is just like our home address. If you want to write to a person, you need to know his or her address so that the postman can deliver the letter. A computer sending information is like a postman. It must know the only "home address" to avoid sending the letter to the wrong person. But our address is expressed in words, the address of the computer is expressed in binary numbers

eth0 is the name set by the system for the network card. If there are al network cards or multiple network cards, there will be names like eth1 and eth2. The name can be set artificially. It is the unique name of the network card in the current computer system

< H2 > after modification, you can use ifconfig command to check whether the modification is successful

Blockchain has been developing for some time now. During this period, people's cognition of blockchain has experienced rapid change

the essence of blockchain is technology? The essence should be traced back until it can not be traced further. Only then can we call it the essence. The essence of blockchain is a technology.
