2. To judge whether a project is safe and deceptive, we can start from the following aspects:

1, white paper

to see a project, the first thing to see is the white paper of the project, which is very important. Usually, the white paper of the project will show the instry demand background, technical background, team information, instry pain points solved, investor relations and the future development plan of the project, etc. When you read the white paper carefully, you will have a clear understanding of the projects you invest in

2, team, consultant and platform boss

we know that investment projects in the investment field, in many cases, will look at people, and investment projects are mostly the founders and teams of investment projects. The blockchain technology talent market is very scarce. Under normal circumstances, there should be senior technical experts in the excellent team. Users must know the relevant information through multiple channels when looking at the project team members. If the project has a star or instry tycoon platform, you should be careful to avoid exaggeration or false publicity of the project

3, whether the project application solves the problem

after having a general understanding of the project, we need to combine with the real background of the instry where the project is located to deeply analyze whether the project has solved some problems of the instry, and whether the application scenario of the project is real and feasible. If the viewpoint of the project is far from the needs and problems of the instry, you should be careful about this project

4. Project code submission Review

users who know a little bit about technology can see the degree of team code submission. If they come out to raise funds without even code, the risk of the project is great

5, the degree of technological innovation of the project

on the level of technological innovation, we need to see whether the project gives full play to the technical advantages of the blockchain, whether there is innovation and whether it is open source. Generally, open source projects will be uploaded to githob. As for the common problems at the bottom of the blockchain, how the project side solves and plans them

6. Pay attention to the fund-raising situation of the project

we can have an in-depth understanding from the following aspects: whether the total amount of fund-raising of the project is reasonable, whether there is excessive additional issuance, whether the token allocation of the project is reasonable, whether there is a record on the official website, whether the team members make fraud, etc

7. Online trading platform

we can also make lateral judgment through the online trading platform of the project. In general, the well-known trading platform has a strong review on the project. If the project is launched on a small trading platform, or even a trading platform that has never heard of, it needs to be treated with caution

8. Refer to the opinions of the third-party project rating agencies

at present, there are not a few third-party project rating agencies in the market. We can refer to the suggestions and opinions of the third-party project rating agencies on the project as a channel for us to understand the project. It is possible that the project rating agencies have different scoring systems for projects, but their final results will not have a big gap, which can be referred by many parties

Yin Zhentao, deputy director of the law and Finance Research Office of the Financial Research Institute of the Chinese Academy of Social Sciences, said that digital currency faces 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

Zhao Zhanzhan, a special researcher of intellectual property research center of China University of political science and law, believes that digital currency has 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

3. Legal risks faced by digital currency: (1) at the macro level, there are legal risks, systematic risks and consumer protection. At present, the legislative problems of e-commerce and e-payment have not been solved, the concept of e-currency and related provisions need to be clarified, and many laws and regulations have not been followed up. Secondly, there is a systemic risk caused by the collapse of a single issuing institution. If a certain issuing institution loses confidence in e-money e to its poor management, other e-money issuing institutions will also face run risk. Moreover, in the absence of standardized supervision, it is difficult for the public to effectively identify the qualification and credit level of issuers. How to effectively prompt risks and protect the rights and interests of the public has become a difficult problem. In addition, the concealment, rapidity and cross-border nature of Internet payment make e-money an inevitable money laundering tool for criminals 2 At the micro level, there are technical risks and credit risks in the main body of e-money issuance. The issuers of e-money in China include banks, non bank financial institutions, Internet enterprises and other enterprises. Due to the weak financial professional foundation of some issuers, especially the lack of mandatory technical security standards in China, there are serious management loopholes and security risks in e-money issuers. System software or hardware failures will affect the availability of e-money. Secondly, the unreasonable structure of assets and liabilities and high concentration of investment will lead to the lack of liquidity and the risk of default. In addition, the payment and circulation of e-money rely heavily on all kinds of networks, and there are all kinds of operational risks, such as deliberate embezzlement of other people's accounts, internal crimes of issuing institutions and malicious intrusion of hackers, which will damage the interests of e-money holders. Bitcoin, Ruitai and other digital currencies are suitable.

4. It's not very safe. Digital currency is different from other real currencies. It's virtual and easy to have problems in the network. My suggestion is not to invest in digital currency.

5. All kinds of digital currencies basically have their own official wallets. In addition, there are many app wallets or web wallets that can store multiple currencies, such as imtoken (it supports Rec20 protocol token storage, so it is troublesome for apple to use, and it needs to be downloaded and upgraded with Apple ID in Hong Kong or abroad); 58wallet (all currency wallet, apple mobile phone and Android can download directly, now only support erc20 protocol token storage, later upgrade can store more currency), of course, there are many other wallets, but I think these two are good to use, hope to help you

6. There should be no one who can make money by hanging the computer all the time. Now there are so many computers hanging all the time. Isn't everyone making money?

7. In theory, digital currency will graally replace paper money, and paper money will slowly disappear. Online payment is relatively safe, but not absolutely safe
digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes
based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds. Compared with paper money, digital currency has the advantages of lower issuing cost, lower transaction cost, traceable, and higher counterfeiting cost. Therefore, digital currency is a trend in the future
in China, some well-known application-oriented digital currencies have emerged, such as Puyin, which is very interesting and known as a standard digital currency.

8. Elytoken e-money has a unique digital encryption security system. The security system will start automatically ring the transaction, and the transaction is guaranteed by the company.

With the advent of digital currency, the encryption algorithm of currency is becoming more and more important. What are the types of passwords

classical cipher types mainly include transposition cipher and rearrangement of alphabetic order messages. For example, "Hello world" becomes "ehlol owrdl"

Diffie Hellman and RSA algorithms have been widely used except for the first public example of high quality public key algorithms. Other asymmetric key algorithms include Cramer schup cryptosystem, ElGamal encryption and various elliptic curve techniques

some well-known cryptosystems include RSA encryption, Schnorr Signature, El Gamal encryption, PGP and so on. More complex password systems include e-cash system, signcryption system, etc. Now more cryptosystems include interactive proof systems, such as zero knowledge proof, which is used for secret sharing

for a long time, information collection and law enforcement agencies have been interested in cryptography. The importance of secret communication is self-evident. Because cryptography promotes privacy protection, it also attracts great interest of cryptography supporters. Therefore, there is a history of controversial legal issues around cryptography, especially since the emergence of cheap computers makes it possible to widely use high-quality cryptography

nowadays, cryptocurrency transactions are semi anonymous, which makes them very suitable for a series of illegal activities, such as money laundering and tax evasion. However, the proponents of cryptocurrency often attach great importance to the anonymity of digital currency and think that it can protect the privacy of users. Some cryptocurrencies are more private than others

Cryptocurrency is a new type of digital asset, which is based on the network distributed on a large number of computers. This decentralized structure enables them to exist outside the control of the government and central authorities. The term "cryptocurrency" also comes from the encryption technology used to protect the network

blockchain is an organization method to ensure the integrity of digital currency transaction data, and it is an important part of many cryptocurrencies. Many experts believe that blockchain and related technologies will subvert many instries, including finance and law. Cryptocurrencies have been criticized for many reasons, including their use for illegal activities, exchange rate fluctuations and the vulnerability of the infrastructure that underpins them. However, digital currency is also praised for its portability, divisibility, anti inflation and transparency
