21 days of digital currency challenge

1.

We need to call the police. This belongs to currency fraud. We can't blindly trust the virtual investment platform that can easily earn a lot of money. Fraud gangs often use "small investment, big income" as t to let investors taste the sweetness first and then increase investment, so as to achieve the purpose of fraud

at present, the so-called "digital currency" in the market is not legal digital currency. The so-called "digital currency" launched by some institutions and enterprises and the so-called promotion of the central bank's issuance of digital currency may involve pyramid selling and fraud. It is necessary for the general public to raise their risk awareness, invest rationally and prudently, and prevent the interests from being damaged

extended information:

five ways to distinguish whether digital currency is MLM currency. virtual currency does not rely on specific monetary institutions to issue, it is based on a specific algorithm, generated through a large number of calculations, is a decentralized way of issuing. Each different terminal node is responsible for maintaining the same account book, and the maintenance process is mainly to package and encrypt the transaction information by the algorithm, while the MLM currency is mainly issued by a certain organization, and the profit is made by pulling the head

2. Transaction mode. Virtual currency is a kind of sporadic transaction formed spontaneously in the market. After the scale is formed, the third party graally establishes an exchange to complete the transaction. The MLM currency is issued by an institution and traded on its own platform

3. The virtual currency itself is an open source program, maintained in the GitHub community. The parameters and methods of the total amount limit are shown in the open source code. The open source of MLM currency is completely ing other people's open source code, and there is no use of open source code to build programs, so its essence is controlled by the website like Q currency

Whether the source code link is given. The general decentralized digital currency will give the source code link in the prominent position of the official website, so as to show the operation mechanism of the monetary system openly and transparently. What MLM currency focuses on is the transaction process of recharge purchase, not to mention its operation mechanism, and even the website does not have the link address of the source code

5. Whether the official website starts with HTTPS. In general, the addresses of the official website and trading website of decentralized digital currency begin with HTTPS. The purpose of this kind of website is to protect users' data from illegal theft. But the official website of MLM currency, trading website and other related websites do not start with HTTPS

2.

Investment is risky, so we should be cautious. A lot of people invest and want to make a quick profit, but this psychology is often mastered by criminals, thus laying a big net of deception. This is not the case. Ms. Chen of Xincheng District, Xi'an City, Shaanxi Province, encountered this incident

Ms. Chen thought that she had met a "noble person" who could make her "rich", so she invested 210000 yuan, but she didn't expect to be blackmailed by the other party soon after the remittance... At this time, she realized that she had met a liar. 210000 yuan was cheated, which made the victim Ms. Chen regret very much

let's take a look at the details

according to the investigation, the police found that there were hundreds of transactions in this account on August 26, when it was frozen, the account amount was as high as 1.18 million yuan, of which Ms. Chen's 160000 yuan was. As the victims in the accounts come from all over the country, the Ministry of public security has stepped in to investigate and chase the victims

It has to be said that there is no pie in the sky for no reason, and there is no free lunch in the world

3. The traditional electronic payment system is built on the basis of credit, relying on the centralized third-party institutions to complete. Digital currency technology such as bitcoin can effectively integrate electronic payment with decentralized system
the monetary property of digital currency has attracted a lot of attention, and the distributed accounting system behind the payment system is undoubtedly a more attractive innovation. In view of the fact that bank deposits and other financial assets are only in pure digital form, this just provides a broader opportunity for distributed accounting system to change the whole financial system
money and payment system are naturally linked. The payment system, the medium of transaction, must be safe and reliable. Any trading system needs an accounting system to record the assets you own in the system
modern payment systems usually use computers to store data. To put it bluntly, the money you deposit in the bank is a series of numbers recorded in the bank account
this article will focus on the recent innovative events in the field of payment, such as bitcoin, a global digital currency, which skillfully integrates the most perfect payment system with the most perfect currency. Users can rely on it to complete the exchange of legal money, commodity trading, purchase services and other activities without the participation of third-party institutions (such as banks). Its innovation lies in that it is not controlled by any centralized banks
bitcoin, the largest digital currency at present, was founded in 2009 and has been supported by thousands of businesses around the world, from pizza to virtual host. Most digital currencies, including bitcoin, have a fixed supply set. This chapter will give a brief introction to its working principle. It will give you a brief introction on how to strengthen the secure payment system with technical means, evaluate the possibility that the old payment system should be replaced by new technology, explain how the distributed accounting system removes many problems in the existing system, and explore new areas where new technology may be applied
many media reported that bitcoin only reported the discussion on its currency property and price. This paper focuses on the revolutionary innovation of the payment system brought by the distributed accounting system of digital currency - the payment system without the participation of any centralized institutions. These innovations can also be expanded in other areas, such as encrypted communications, decision-making, P2P networks
central banks have the responsibility to stabilize their monetary and payment systems to ensure the stable operation of the economy. The recent innovation in payment technology has been related to the topic of "digital currency". Most of the payment systems in today's economies follow the pattern of centuries ago, that is, they use centralized institutions to carry out secured transactions. For example, the Jinpu bank appeared in the 16th century. People can exchange physical gold for gold tickets, which can be used as gold coins or gold coins, but can not be used across banks. With the requirements of social development, there is an increasingly urgent need for an inter-bank payment system, now the practice is a variety of UnionPay organizations
bitcoin, Ruitai coin, Weimeng coin, Laite coin and other digital currencies may disappear in the future, because now it is only a small experiment, but this idea may continue.

4. Both domestic Shenyu mine and bitcoin mine in China are OK. Of course, there are many well-known mines abroad that can be mined. You said that the software is now a long time ago, when the configuration of a higher computer or graphics card mining, more trouble. Now if you are still mining those equipment, I suggest you do something else meaningful. Now we need to buy professional ASIC mining machine. Even so, it is difficult for retail investors to recover their capital. Of course, you can also buy cloud computing power mining. Now mining is fighting for electricity price and energy consumption. If these two points have advantages, mining is OK. If these two points can't be achieved, it's no use. Of course, it doesn't rule out that the electricity charge you add is free. This can also be mined

you need to download a bitcoin wallet and back it up. Just keep bitcoin in your wallet. However, if you don't know the technology, I suggest you store bitcoin in your online wallet. Now the technology of online wallet is very mature. If you still don't understand, go to bitcoin home to see some suggestions from netizens.

5. It is wrong to say that China's digital currency comes from the people, because it comes from the present. Science.

7. If the digital currency is 100%, sokon can develop in 30 days.
