Digital currency exchange hacked

1.

Basic routine: the "trading market" of MLM digital currency is basically controlled by specific institutions. In order to attract investors' investment in the early stage, the currency price may be very high. Once the time is ripe, it will be sold intensively, and the price will plummet, and the investors will lose all their money

There are three characteristics of digital money MLM:

1. Digital money is a real proct, and it is highly packaged

2. The participants can get a head pulling reward, and the prize is the digital currency itself

3. Digital currency will appreciate with the increase of participants in the scam. In the cycle of digital currency appreciation, the number of participants who can obtain digital currency will also increase, and the participants, including the lowest level participants, will also gain, but in the cycle of devaluation, the bottom level participants often lose a lot

in 2017, the Internet Finance Association of Jiangsu Province issued the "internet pyramid selling identification guide", which named 26 so-called digital currencies as illegal pyramid selling projects covered or suspected to be covered with digital currency. They are: treasure money, Baichuan money, SMI, MBI, mark money, Diablo money, mmm, Fuda compound wealth management, carat money, V treasure, Vicat money, petroleum money, Huaqiang money, CB aiib Hong Kong Group, Yuansheng, Morgan money, beta money, WorldCom, u money, Jubao, 21st century fox, Wanxi wealth management, Wanfu money, Wuxing money, Yi money, Zhonghua money, etc

five ways to distinguish whether digital currency is pyramid selling currency:

1. Issuance mode

virtual currency does not rely on specific monetary institutions. It is proced by a large number of calculations according to specific algorithms, and is a decentralized issuance mode. 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 spontaneously formed in the market, which is graally completed by a third party establishing an exchange after the scale is formed. The MLM currency is issued by an institution and traded on its own platform

3. Implementation method

virtual currency itself is an open source program, which is maintained in 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

4, whether to give the source code link

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. The MLM currency focuses on the transaction process of recharge purchase, but does not mention its operation mechanism. Even the website does not have the link address of the source code

5, whether the official website starts with HTTPS

generally, the addresses of the official website and trading website of decentralized digital currency start with HTTPS, and the purpose is that this kind of website can well protect the user's data from illegal theft. But the official website of MLM currency, trading website and other related websites do not start with HTTPS

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. It's not a scam. Digital currency is the digital representation of legal tender issued or recognized by the government.

at present, the vast majority of digital currency transactions are concted in exchanges. Among the numerous exchanges, bitfinex, binance, okex and so on are well-known

However, bitcoin and other digital currencies, as decentralized assets, have to be traded in a centralized exchange, which seems to have hidden contradictions and dangers

1. Problems and challenges of stock exchanges=“ //www.yuanxue365.com/en/img_fd039245d688d43fdf16c83b761ed21b0ff43bbf ">

in February 2014, Mt. GOx, the world's largest bitcoin exchange at that time, was stolen 850000 bitcoins, and the price of bitcoin suffered a" cliff "crash on that day. Later, it was revealed that Mt. GOx was in fact a thief, and only 7000 bitcoins were actually stolen

in August 2016, bitfinex, the largest U.S. dollar bitcoin trading platform, suffered a security vulnerability, resulting in the theft of 120000 bitcoins, which was worth $65 million at that time. If converted into the price in December 2017, it would be worth nearly $2 billion

on December 19, 2017, South Korea's youbit exchange was attacked by hackers and lost 4000 bitcoins, and the exchange declared bankruptcy

on December 21, 2017, the Ukrainian liqui exchange was stolen 60000 bitcoins, and the unit price of bitcoin plummeted by US $2000

in 2018, such a drama will only continue

in addition to the threat of hackers, traditional exchanges also have some inherent shortcomings, such as lack of supervision and inefficiency. The security of the exchange for investors can only rely on its own credit, and the cost of running is very low. The stock exchange is regulated at the national level, but there is no such sword of Damocles on the top of the digital currency exchange. Moreover, in an exchange, the same order can only be submitted to one exchange. After the user places an order, the funds used for the transaction will be frozen and can only wait for the completion or cancellation of the transaction. These are undoubtedly inefficient

All in all, the problems of exchanges are the problems of centralization

2. Decentralization of exchanges=“ //www.yuanxue365.com/en/img_86d6277f9e2f070889a173c9e224b899a801f257 ">

(1) the progress of the exchange itself

the upgrade of security means is various. At present, the best use is cold wallet, that is, to keep the digital currency in the offline U disk. At the end of 2017, when the YouTube exchange was attacked, 75% of its assets were withdrawn into the cold purse in time to avoid greater losses. However, it seems to be a helpless way to protect the online assets by offline means. Of course, there should be many other methods, which will not be repeated here

(2) the representative of cross ledger transaction is ripple network, and the operating company is ripple labs, which is a semi centralized system. Ripple is a decentralized clearing agreement. In order to solve the high cost and delay of inter-bank clearing, its base currency is XRP. Ripple network can connect all kinds of assets, such as US dollar, RMB, Japanese yen, bitcoin, etc. to its own network. In this system, U.S. dollars or bitcoin can be converted into reborn currency, and then reborn currency can circulate freely in the network, just as a highway is built between various assets. Due to the support of major banking institutions, the reborn currency achieved nearly 300 times growth in 2017

(3) decentralized exchange

some teams try to use blockchain technology to build a decentralized exchange. This kind of decentralized exchange, to some extent, is an extension of cross ledger trading

bitshares is the most representative of early rising projects. It builds a blockchain development platform with servers scattered all over the world. Even if some of them are attacked, the system will not collapse. Anyone can transfer money and borrow money freely on this platform, and can also quickly build a centralized exchange based on this platform. In order to ensure stable value, bitstocks also require three times of digital assets as collateral. At present, bitstocks are running fairly well

later, with the development of Ethereum and smart contract, the x x protocol came into being. This is an open protocol running in the Ethereum blockchain and a decentralized exchange in the Ethereum ecosystem. The agreement has attracted many investors. At present, it has completed financing and started to build open source software tools and infrastructure. Of course, there are many competitors. Ether Delta, IDEX and oasis DEX are trying to provide similar functions. Moreover, it is a smart contract system based on Ethereum, which only supports erc20 token. If other smart contract public chains start to rise, the demand will be reced

in addition, there are some teams that are entering, such as the domestic road seal agreement, looping (LRC) in English. They adopted a design similar to the X protocol, and also introced a fast payment function similar to the lightning network. It is characterized by trying to match multiple exchanges, the user's order can be broadcast to multiple exchanges, and completed by different exchanges. Moreover, the user can still use the account funds after placing an order, and the user's behavior of transferring part or all of the funds is equivalent to partial or total cancellation. To some extent, it improves the breadth and timeliness of the transaction. However, this system seems to have damaged the "power" of the existing exchanges. Whether we can persuade everyone to play together will be a difficult problem

At present, there is still a long way to go for the construction of decentralized exchange. In 3-5 years, traditional exchange will still be the main battlefield of digital currency

However, in the future, it is worth looking forward to let the decentralized digital currency get rid of the shackles of centralization

This is a very interesting question. The currency market and the stock market need to be stratified and diversified to allocate their positions. Learning to diversify the layout to cope with multiple changes is a necessary condition for the survival of this market

My personal suggestion is to build 5 / 3 / 2 positions. 50% of mainstream hard currency, bitcoin, Ethereum, lightcoin, bitcash, ethereal classic, etc

If you are cheated, you can choose to report to the police in time for recovery

digital currency is an emerging technology that can improve transaction efficiency, but it is targeted by lawless elements to carry out pyramid selling and fraud in its name. The official website of the monetary Bureau of the people's Bank of China issued the risk warning on issuing or promoting digital currency in the name of the people's Bank of China. The central bank indicated that recently, indivial enterprises falsely used the name of our bank

falsely claimed that the central bank issued digital currency promotion team in an attempt to deceive the public and take the opportunity to make huge profits. The central bank has not issued legal digital currency, nor has it authorized any institution or enterprise to issue legal digital currency

extended information:

the introction of digital currency transactions is as follows:

the so-called "digital currency" in the market is not legal digital currency. At the same time, 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

the "internet pyramid selling identification guide" issued by Jiangsu Internet Finance Association named 26 kinds of so-called digital currencies as illegal pyramid selling projects under the guise of digital currency. They are: treasure money, Baichuan money, SMI, MBI, mark money, dark money, mmm, Fuda compound interest financing, etc
