Enjoy virtual currency
The digital currency wallet is the hardware wallet, which means that the private key of digital assets is stored in a single chip, isolated from the Internet, plug and play. Hardware wallet can't guarantee 100% security. For example, if a geek gets your hardware wallet and doesn't know your private key, it may be cracked by violence. It's just one of the safest storage methods compared to other storage methods
many block chain entrepreneurs at home and abroad are optimistic about the development of this field, so they begin to build more hardware wallets. In the case of the exchange being stolen a lot of money and the software wallet being stolen from time to time, many investors regard the hardware wallet as the last moat
extended information:
whether the hardware wallet is safe
the hardware wallet can not guarantee 100% security. For example, if a geek obtains your hardware wallet, it may be cracked violently even if it doesn't know your hardware wallet immediately. It's just one of the safest storage methods compared to other storage methods
of course, there are exceptions, such as you have unlimited brain power and never forget. It's better to save it anywhere than in your own mind
It's said that the currency circle has been going on for one day and the stock market has been going on for one year. Although it's a bit exaggerated, it's not unreasonable. In recent days, bitcoin has gone up sharply, but it has come down slightly today. It's estimated that no one can match the speed of the bull bear conversion in the currency circle. However, among many virtual currencies, how can we find high-quality projects? Xiaobian thinks that the bull market is not surprising. The key point is that the bear market still insists on giving weekly reports, at least for the projects with reliable teams. Today Xiaobian still brings you weekly reports of some high-quality projects. The following is the latest weekly project progress report (April 9-April 15, 2018) released by ubtc team. The specific information is as follows:

It claims to build an "IP asset exchange", issue its own token for a high-quality IP, solve the problems of realization, protection, and management of the cultural and creative IP instry, and build a weakly centralized, traceable, digital, and capitalized cultural and creative instry ecosystem. But in fact, when they enter their community, the nature of the swindler will be exposed. They promise to go to the major exchanges such as Shanghuo coin, promise that the opening price will not be less than 2 times of earnings, promise that they will only go up but not go down, promise that they will not break, promise that they will not attract funds, promise to carry out pull propaganda, and hope to raise the vigilance

In the official letter of Xiangcheng District of Suzhou, enterprises, institutions and management committees of Xiangcheng District are required to sign a digital currency agreement with the wage paying bank, install digital wallets for all staff (except retirees), and pay 50% of the monthly salary in the form of digital currency
this is the first practical application of the central bank's digital currency since the R & D news, which is a historical moment worth remembering
let's review the development of DCEP:
in 2014, the central bank set up a special research group on legal digital currency
in 2016, it set up a digital currency Research Institute on the basis of the original group
in June 2018, it set up Shenzhen Financial Technology Co., Ltd.
in August 2019, the central government issued a document to carry out digital currency research and mobile payment pilot in Shenzhen
on October 29, 2019, At the "2019 Bund financial summit", Huang Qifan, vice president of China Center for international economic exchange, said: "the digital currency DCEP launched by the Central Bank of China is a new crypto electronic currency system based on blockchain technology." This is the debut of DCEP
On April 3, 2020, in the "national teleconference on money, gold, silver and security work", the central bank said that it would "unswervingly promote the research and development of legal digital currency" On April 10, Zhou Xuedong, director of the general office of the people's Bank of China, pointed out at the "first quarter financial statistics press conference" that "with regard to digital currency, the people's Bank of China is advancing in an orderly manner according to the original plan."on April 14, the central bank's digital currency DCEP took the lead in the internal test of ABC
on April 16, Xiangcheng District of Suzhou realized the implementation of the first application scenario of central bank's digital currency DCEP, using "digital wallet" as the payment channel and issuing it in the form of transportation subsidies
judging from various actions, the central bank's plan for digital currency is well prepared and in an orderly and continuous progress
why DCEP
from the national level, it is well known that the macroeconomic regulation and control means of sovereign countries are mainly through monetary policy and fiscal policy, just like the current global lack of liquidity e to the epidemic, China's economy is stimulated by interest rate rection and government spending, but the funds are transmitted layer by layer, and there are few funds really used for the target range
if we use the central bank's digital currency system, we can analyze and track a large number of transactions, and use the most direct and efficient means to put funds where they need, so as to release liquidity and benefit the people
from the international level,
the use of blockchain technology can realize the review of national credit and increase the credit of the country's monetary system. With the increase of GNP, credit must also increase, and the process of RMB internationalization will be more rapid
this is very simple to understand. Blockchain technology makes it impossible for asset certificates to be forged and makes credit verifiable, which is naturally concive to RMB internationalization
Last year, the World Bank Group and the International Monetary Fund (IMF) issued a report that up to now, nearly 70% of the central banks are studying the digital currency of the central bank, which also shows that the digital wave is the general trend. At present, the central bank's digital currency DCEP is likely to be used on a large scale ahead of other countries in the world, and the era of digital currency is comingthe era of digital economy is getting closer and closer
today's era is a digital era. With the comprehensive rise of technological innovation and digital economy, science and technology has changed from the initial role of a tool to the backbone of financial reform. The continuous collision and integration of digital five complete genes (whole airspace, whole process, whole scene, full analysis, and full value) and financial instry not only changes the settlement and settlement methods and sovereign currency issuance mechanism among indivials, enterprises, and countries, but also greatly improves the operation efficiency of instrial chain, and brings the development of the whole economic society and human progress
if blockchain technology will "genetically transform" all walks of life, then digital currency will "genetically transform" the financial instry. Looking forward to the future, the in-depth integration and transformation of traditional instries by blockchain, artificial intelligence, cloud computing, Internet of things and other technologies will lead us into a new era of digital economy
in short, the era of digital economy is getting closer and closer to us
the implementation of the central bank's digital currency is bound to bring disruptive changes to the existing financial market and breed huge wealth opportunities. The future has come, the wind has come, keep up with the pace of the instry, accurately grasp the future trend, and quickly seize the blue ocean of wealth business
