Why is the bitcoin world not safe
bitcoin is just a game. If it is promoted as a tool to get rich, it can be regarded as a fraud. Just like the currency in other online games, the only difference is that bitcoin has been standardized since the game was first formulated. It can't be issued indiscriminately, so it can keep its value better than other virtual game props. It is equivalent to the online collection. Bitcoin is a prop in the game, and its value is reflected in the recognition of bitcoin by players: more people play, the value of props in the game is higher; The risk is that he is not the only game, and his algorithm is not the only one. Maybe someone will be able to make other special coins soon. All you need to do is promote the game and sell your props. As for money, bitcoin does not have the basic attributes of money, such as unfair initial distribution and insecure circulation. Money needs to be maintained by the state machine
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked
4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30

bitcoin is a fraud, so we must be cautious in investment and financial management
even if it is called "hard currency", the price of gold will not only rise but not fall. There is no bubble in gold, but the price is too high, there is a bubble, and the bubble will eventually burst, such as virtual currency such as bitcoin. The more general virtual currencies, the closer bitcoin's value is to zero
this kind of currency, which is a purely calculated digital symbol, has no asset support, no financial revenue and expenditure, no cash reserve and no use value. It is only a circulation symbol. Once it loses its credit guarantee, it is a pile of beautiful printed waste paper. Investors should be alert that there is no so-called safe investment in this world, and all investments are risky
the people's Bank of China and other departments issued a document to severely punish the above-mentioned behaviors, making it clear that token trading is not protected by law. With some virtual currency trading platforms turning to overseas, speculative money speculation has also turned to "underground". In the face of continuous renovation, on the basis of continuous strict supervision, government departments should constantly upgrade the means and ability of supervision, and continue to increase publicity and crackdown on popular science, so as to avoid the masses being deceived
extended information:
investing in virtual currency is more of a kind of speculation. Investors should strengthen their risk prevention awareness and identification ability. Without confirming the identity of the other party, they should not be involved in money transactions, trust low-risk and high return investment procts, especially not join the investment and financing group without verification, These are often well-designed traps by telecommunication network fraudsters
it's better to purchase the investment and financial management accompanied by the children, and learn from the official and authoritative channels, and report to the police in time when they are found to be cheated. Properly protect all kinds of account password, identity information, etc., don't tell others easily. Any reference to the need for transfer and remittance should arouse high vigilance and consult with trusted acquaintances

Bitcoin is a kind of P2P digital currency
reasons for blocking:
1. Vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
The transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed The price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading4. The public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless

the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner
This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 millionbitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
bitcoin:
is an electronic currency proced by open-source P2P software. Digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin."
bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. Since bitcoin was born with an algorithm, it was stipulated from the beginning that all bitcoins in the world would not exceed 21 million bitcoins. Because bitcoin is not regulated by the government, it is not subject to inflation constraints and external control
people use the computing power of CPU and CpG to "mine" to unlock the new bitcoin. To put it figuratively: bitcoin is equivalent to a gold mine created by people using computers. The setting of this gold mine is limited. The upper limit is 21 million bitcoin. People dig out bitcoin one by one just like miners using the principle of CPU computing
the principle of bitcoin, the distributed characteristics of P2P and the design without central management mechanism ensure that no institution can control the value of bitcoin or create inflation. This decentralization makes it a more secure and value preserving "virtual currency"
But in fact, netizens, as well as traders and investors of bitcoin, do not see one of the biggest drawbacks of bitcoin: bitcoin is not uniqueWhat do you mean? We think that bitcoin is the only one with a cap of 21 million, which seems to have the function of preserving value. But the principle of bitcoin algorithm is not only applicable to "bitcoin", a kind of currency from Japan. Every computer engineer can develop the corresponding algorithm, make a man-made gold mine, and control its upper limit. In this way, every country, every region and every person can develop countless algorithms. Then the market will be full of virtual currencies such as "bitcoin a", "bitcoin B", "bitcoin C", "bitcoin D", and so on. By that time, who are you going to invest in? You can create your own currency
this hidden danger is not a dream. In fact, it has already started. You can log on bitcoin's official website in China. You will find that in addition to bitcoin, there is now another kind of thing called "Yuanbao coin". This is an algorithm similar to bitcoin developed by a Chinese development team. It also has the same upper limit. The same people can't control it and dig Yuanbao coin out through "mining"
if they can do this, I believe many computer workers can also write their own "Yuan Bao coin", "gold and silver coin", "China bitcoin" and "Shanghai bitcoin". Bitcoin, as the first code to appear, has no credit support from the Central Bank of any country. It has value only because of the scarcity of 21 million. In fact, this scarcity does not exist, because everyone can develop the virtual currency code, and then people from all over the world can mine it. So what's the price of bitcoin? There are limited kinds of metals on earth, so each metal has different value according to its quantity and scarcity. But the bitcoin like code in the network world is infinite. As long as people are willing, they can create unlimited kinds of bitcoin code. Tell me, is bitcoin still valuable
blockchain Technology:
the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database
the essence of blockchain is to achieve the goal of decentralization and disintermediation through a new generation of data technology, so as to transmit value more transparently and efficiently. This kind of point-to-point verification will proce a new network "basic protocol" which is different from TCP / IP in the Internet era
blockchain shows us a world in which all assets will be digitized. In a valuable Internet, the transfer of assets will be as fast, convenient and cheap as the transmission of information today
the significance of blockchain is not the wealth of digital currency, but the value transmission of its technology itself. Therefore, Ma Yun has repeatedly separated blockchain from digital currency, and stressed that the extent to which blockchain technology will change the world is beyond people's imagination
difference:
blockchain is a technology, based on blockchain technology, there can be many applications
bitcoin: is one of the most popular and well-known applications

Trump has issued a U.S. ban on petrodollars, banning Americans or anyone in the United States from buying new Venezuelan petrodollars. As Venezuelan President Nicolas Maro said, this is the first executive order related to cryptocurrency issued by the president and another blow to an already suspicious virtual token. Presumably, the cryptocurrency is backed by oil reserves
According to cryptocurrency regulatory experts, Trump's ban is a predictable move“ Although Venezuela's attempt to issue cryptocurrency is novel, it is not new that the United States restricts financial transactions with countries subject to sanctions. " "The issue of cryptocurrency will not help Venezuela escape sanctions," said Jerry Brito, executive director of coin center, a think tank
