Overall monetary figures

1. Currency digitalization is like WeChat Alipay, and bankcard pays
1. digital currency facing two risks. The first is the technical level. Digital currency relies on blockchain technology and a system, which will make it suffer from security impact, such as hacker attacks on computer systems. We have seen many practical problems in this process< Another risk of digital currency is credit risk. Because there are middlemen in digital currency transactions, these middlemen are different from real organizations. In reality, organizations can be seen and felt, but the middlemen of digital currency are on the Internet, so the risk is greater
3. Digital currency has the characteristics of anonymity, quickness and irrevocability. In addition, bitcoin and other digital currencies have high circulation in the world, so many criminals use digital currency as a new money laundering channel. Moreover, there are many different ways to realize money laundering through digital currency. Generally speaking, the probability of new money laundering being found and investigated is lower than before. Many countries have no effective means and technology to combat money laundering through digital currency. These factors lead to criminals prefer this way of money laundering
investment is risky and business should be cautious

2. For many people, the concept of digital currency is a mystery. But there is no doubt that digital currency is different from virtual currency

virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency

in 2013, the central bank, together with five ministries and commissions, issued the notice on preventing the risk of bitcoin, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, not in the form of currency and legal currency< At the same time, digital currency is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes.

Generally, the excellent digital currencies are mostly imported procts, such as bitcoin, Leyte coin, ether coin and so on. However, the domestic Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects of European crowdfunding are excellent digital currencies

digital currency (English: digital currency) is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank

it is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography

4.

Digital RMB is the legal digital currency not yet issued by the people's Bank of China, namely "digital currency electronic payment" (DC / EP). Based on the generalized account system, it supports the loose coupling function of bank account, is equivalent to banknotes and coins, and has value characteristics and legal compensation

on August 14, 2020, the Ministry of Commerce of the people's Republic of China issued the "overall plan for comprehensively deepening the innovation and development pilot of service trade", which mentioned that "digital RMB pilot projects should be carried out in Beijing Tianjin Hebei, Yangtze River Delta, Guangdong, Hong Kong, Macao and other pilot areas in central and Western China."

on October 8, 2020, the Shenzhen Internet Information Office of Guangdong Province announced that in order to promote the construction of Guangdong, Hong Kong and Macao Dawan district and in combination with the local consumption promotion policy, the Shenzhen Municipal People's government recently launched a pilot project of digital RMB red envelope with the people's Bank of China

digital renminbi is what

first, the most typical question is what is the difference between digital Renminbi and Alipay and WeChat payment? p> Basically speaking, digital RMB is equivalent to banknote and coin RMB, which is a legal currency with value characteristics and legal compensation. The three party Internet payment methods such as Alipay and WeChat payment mainly rely on deposit money transactions in commercial bank accounts, which is essentially a payment channel for legal tender. Digital Renminbi belongs to M0, that is, the category of cash in circulation. The money that people put in Alipay and WeChat accounts are deposits of non deposit financial institutions. They belong to the category of M2, that is, broad money. p>

CCTV reported that compared with the third-party payment tools, the use of digital RMB is more convenient:

the payment path is short: there are only two points of payer and payee, and the transaction can be completed within a few milliseconds without any third-party platform

double offline payment: when the mobile phone has power, it can spend digital RMB even if there is no network

controllable anonymity: to protect the privacy of consumers, in addition to the government departments investigating illegal transactions within the scope of authority, merchants and third-party payment platforms have no right to obtain the payment data of consumers, and consumers are free from marketing intrusion

in addition to the obvious advantages of easy use and cracking down on counterfeit money, the future implementation of digital RMB can better help the state to regulate currency circulation, fight corruption, anti money laundering, and fight crime; In terms of macro-control, it can optimize monetary policy, achieve targeted poverty alleviation, accurately support the development of real economy, and promote the internationalization of RMB

5. The models of mining machines in the Institute of mining and gold will be adjusted according to the market. Now there are Shenma M20S, Shenma m21s, Avalon A10, ant S17, etc., which are the mainstream mining machine models in the instry.

6. Sumitomo 350 capacity 1.6 cubic meters. Sumitomo 460 Dou Rong 2. These two models can open mines. Sumitomo has low fuel consumption, fast combination action, 350 imported 190W, 460 imported 280W
it's not easy for Komatsu and Carter to import. As I said upstairs, we still need imported cars for mining, with guaranteed quality and rability. Carter's car is strong, but it consumes too much fuel and costs too much. Komatsu's cars are medium, but Komatsu's brand awareness is high, and imported cars are not easy to get. Sumitomo and Komatsu are comparable in performance, but Sumitomo is more fuel-efficient, and its mining efforts are not bad, but its popularity is not as high as Komatsu Carter, because it entered the Chinese market relatively late.

7. Mining is mainly enough graphics card, memory and CPU requirements are not high. The problem is that the graphics card needs at least gtx1060. And generally use the graphics card shelf, with six graphics cards at a time, so the motherboard requires six graphics cards and six graphics card slots, or use the adapter card to drive six graphics cards
in addition, the power consumption of the mining machine is very serious. If you turn on the machine 24 hours a day, you may not be able to earn back the electricity bill at home
Mining studios are usually built in remote places where there are private small hydropower stations, because the electricity price of private small hydropower stations is low.
