Advantages and disadvantages of website virtual currency
1、 Common analysis of virtual currency (1) bitcoin solution is designed and created by Japanese programmer Nakamoto (alias) in 2009, and it is the most successful and controversial network currency at present. Bitcoin scheme is based on P2P network architecture, which has been operating in the world, and can be used for all kinds of virtual and real goods and services transactions
In theory, if the existence of network currency affects the demand for the central bank's liabilities, and then interferes with the central bank's open market operation, it will have an impact on a country's monetary policy and price stability. However, from a practical point of view, the premise of network currency affecting price stability includes the following three aspects:(1) from the analysis of the impact on the amount of money, although it is difficult to analyze the extent to which the network currency scheme creates money in the case of lack of information
However,however, most Internet money systems operate in prepaid mode, that is, issuing Internet money when the real money is exchanged in and withdrawing money when the real money is exchanged out. In the famous network currency scheme, the supply of money is stable and the supply is small, but we still need to be vigilant whether it can ensure that the money supply will maintain a stable level in the long run, and the impact of the change of exchange rate between network currency and real currency
(2) from the analysis of the impact on the speed of money circulation, the use of cash and money statistics, the impact of the technological innovation brought by the network currency scheme on the speed of money circulation is not clear
as an Internet instry, it largely depends on the number of active internet currency scheme users. If the network currency is widely accepted, it will have a substitution effect on the real currency of the central bank, thus recing the use of cash in transactions
in this case, the scale of the central bank's balance sheet will be reced, and its ability to influence short-term interest rates will also be weakened. The central bank will need to fight against risks through ways such as setting minimum reserves for cyber currencies. Substitution effect will aggravate the difficulty of monetary statistics and affect the relationship between monetary statistics and inflation, which is not concive to the realization of long-term price stability. In addition, the issuance of network currency outside the central bank and the expansion of virtual credit will have an impact on the central bank's interest rate decision in the economy and weaken the central bank's monetary control
(3) from the analysis of the interaction between network currency and real economy, network currency can act as a real commodity trading medium and have an impact on real GDP
The influence of network money on real money supply depends on two aspects: one is the substitution effect of virtual economy on real economy; the other is the substitution effect of virtual economy on real economy; The second is the crowding out effect of Internet money on real money, that is, with the increase of the total amount of Internet money, the amount of cash held by the public in real life decreases, resulting in the decrease of cash / deposit ratio and the increase of money multiplier. In reality, the network virtual currency scheme will not affect the price stability at this stage, and the money flow speed will not be significantly affected in the short and medium term. However, the interaction between network currency and real economy deserves attention (2) financial stability risk when the virtual currency scheme operates outside the banking system, the most important factor of financial instability lies in its connection with the real economy, namely exchange rate and exchange market. Obviously, the closed network currency scheme and the one-way flow network currency scheme are not affected, so we should focus on the two-way flow network currency scheme. The value of two-way network currency depends on the level of money supply and demand in the exchange market. A big difference between network currency and real currency is that the network currency scheme is not based on the country or currency region, and the influence of virtual economy intensity, trade or proction capacity on its exchange rate is limited. The price of virtual money and its fluctuation depend on five factors:(1) money supply and other actions taken by currency issuers. For example: to achieve a fixed or semi fixed exchange rate by intervening in the market
(2) the network currency scheme shows network externality, and its monetary value depends on the number of users and merchants. As the number of consumers and businesses increases, their monetary value will increase accordingly. In addition, the exchange rate of network currency with small transaction volume fluctuates more(3) the virtual community with clear and transparent policies and advanced security measures is easier to boost confidence and the currency is stronger
(4) the reputation of network currency issuers in fulfilling their commitments. There is no "lender of last resort" in the virtual community, and the trust gained by the issuer is crucial to the exchange rate of internet currency
(5)
speculation on the future value of Internet money and cyber attacks on virtual communities. Due to the immaturity of the system, low trading, speculative activities and network attacks, the two-way network currency scheme is inherently unstable
qualitative. At present, the trading volume of these network currencies is small and the correlation with the real economy is low, so the stability of the financial system will not be affected. However, if Internet money becomes a substitute for traditional money in the future, it will bring instability to the financial system and even distort the relative prices of goods and services. The impact of network currency system on the financial system largely depends on the number of active users and the number of merchants who are willing to accept virtual currency for real transactions. In addition, virtual currency has only exchange value and no use value. Generally, network currency is not based on assets with intrinsic value and is not supported by central bank credit. At present, these network monetary systems are not allowed to lend
or borrow funds, so it can not pose a threat to the stability of the financial system, but we should pay close attention to its development. If there is any change in the future, it will undoubtedly have an impact on the financial system
in a specific virtual community, virtual currency payment activities have evolved into a "real" payment system, facing typical risks related to the payment system: credit risk, liquidity risk, operational risk and legal risk. The nature, scale and ration of these risks are largely determined by the design of the system or the degree of lack of liquidity, so it is difficult for the network virtual currency scheme to avoid or control these risks. According to the core principles of payment system (CP) issued by the bank for International Settlements (BIS), the network virtual currency scheme does not conform to most of the contents of CP, and does not belong to the systemically important payment system. Therefore, it will not cause
or transmit shocks in the global financial system. At present, there is no systematic risk in the network currency system outside these virtual communities
2. Lack of corresponding supervision and protection mechanism
in the real economy, the central bank plays the role of lender of last resort and has no default risk, so it can take actions in the case of payment crisis or unpredictable liquidity shortage to avoid chain reaction. However, in the network virtual currency scheme
it is impossible to use network currency as settlement asset. Because network currency simply depends on the credibility of the issuer, it can not be widely accepted as a means of payment, so network currency can not be regarded as a safe currency. In addition, commercial banks are required to accept prudential supervision, which reces the possibility of default, and the security of money in commercial bank accounts is higher than that of network currency. A fundamental risk of network currency is that the settlement institution of network currency scheme is not subject to any supervision, no institution is responsible for its behavior, and there is no investor / depositor protection mechanism, which causes the user to bear all the risks
supervision and the anonymity, invisibility and difficulty in tracking of its transactions, the network virtual currency scheme is very easy to be used by terrorist activities, fraud, money laundering and other illegal activities. At present, many government departments in many countries are considering whether to recognize or
legalize these virtual schemes and bring them into the scope of supervision, so as to support the innovation of currency and payment forms, protect the rights and interests of consumers and financial stability, and inhibit the use of virtual currency schemes to engage in criminal activities
at present, the uncertainty of the legal status of the virtual currency scheme may also bring challenges to the government authorities (5) reputation risk of monetary authority the reputation of Monetary Authority (central bank) is the key factor to determine the effectiveness of monetary policy. The public's trust in fiat money is closely related to the image of the central bank, which pays close attention to its reputation. The ECB defines reputation risk as the risk of deterioration of reputation, credit or public image. As the network currency scheme is related to money and payment, it is generally believed that it belongs to the responsibility of the central bank, so we should be alert to the reputation risk it may bring to the central bank. However, in the case of small scale, the impact of the failure of the network currency scheme is limited, but its high volatility and instability also aggravate the possibility of failure and attract extensive media coverage. If the network currency is allowed to develop continuously without
regulation, the central bank may be considered as dereliction of ty and affect its reputation (6) the risk of investors' loss
for exchange value, the public has a higher recognition of the investment value of network virtual currency, and it is investment based transactions that accelerate the formation of virtual currency market. Like other investment markets, participants in virtual money market will also face potential losses caused by market risk, credit risk and policy risk. Take bitcoin as an example: from 2009 to early 2010, bitcoin was worthless; In the summer of 2010, bitcoin trading began to enter the golden
period. As the supply was far less than the demand, the value of online trading began to rise. In early November, bitcoin was silent at 29 cents for many days, and then jumped to 36 cents; In February 2011, bitcoin continued to appreciate, and its exchange rate with us dollar
reached 1:1; In 2013, the price of bitcoin achieved a "Big Bang" growth, and hit US $1242 on November 29, 2013, surpassing the gold price of US $1241.98/ounce in the same period. Fierce price fluctuations make market participants face huge speculative risks. Unlike mature capital markets such as stocks and bonds, the depth of bitcoin market is insufficient, and it is mainly held in the hands of large investors with low degree of diversification. Bitcoin price is easily affected by large investors' buying and selling behavior, and also easily manipulated by speculators. At the same time, different countries have different attitudes towards bitcoin, Germany, the United States and other countries hold an open and supportive attitude, and Thailand, Brazil and other countries regard bitcoin related activities
as illegal. Every country's attitude and measures will have a significant impact on the price of bitcoin, especially in the short term
virtual currency is always inferior to real currency< br />
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Fuyuan coin (FTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency
websites that can be traded include Fuyuan currency trading platform, bitcoin China, etc
it is recommended not to play with these coins, which is very risky. At first, you may only sign in every day to earn money, but when you hear or see that many people have made a lot of money because of these coins, you will also invest a certain amount of money. When you taste the sweetness again, you will invest more money; Or you will be driven by huge profits to get a reward. This is a typical Ponzi scheme
since 2013, the popular virtual currencies are bitcoin, Laite coin, Ruibo coin, Fuyuan coin and doggy coin.

in 2009, Nakamoto designed a kind of digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura
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. On January 11, 2017), the Shanghai headquarters of the people's Bank of China and the Shanghai Municipal Finance Office carried out on-site inspection of bitcoin China, focusing on whether the enterprise carried out credit, payment, exchange and other related businesses without permission or license; Implementation of anti money laundering system; Fund security risks, etc. On January 12, 2017, the business management department of the people's Bank of China also entered the trading platforms such as "fire coin net" and "currency bank" in Beijing
on May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! More than 40 hospitals across the UK have been widely hacked, leaving the NHS in chaos. The campus networks of many colleges and universities in China were also occupied. Nearly 74 countries in the world have been seriously attacked
currency characteristics
Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
Global Circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
exclusive ownership: the private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay
cross platform mining: users can explore the computing power of different hardware on many platforms
advantages
complete decentralization, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm. Anonymity, tax exemption and supervision free. Robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
cross border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records. It's hard for a cat to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency. But these counterfeit currencies are fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. Many Shanzhai coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical
disadvantages
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. Transaction confirmation takes a long time. 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 trading. 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.
1. Bitcoin
since its release in 2009, bitcoin has become the most famous virtual currency. This virtual currency was developed by indivials or organizations under the pseudonym of "Nakamoto Tsung" (whose real identity has always been unknown), and is mainly used by online merchants. However, in recent years, some small physical merchants have begun to accept bitcoin payment. Through complex algorithms and a large number of computing resources, users can obtain bitcoin through "mining". Of course, they can also purchase bitcoin through exchanges or services like bitinstagnt and coinbase. The total amount of bitcoin that can be mined is about 21 million, while the current mining amount has exceeded 11 million. Bitcoin has attracted the attention of Western Union, MoneyGram and paypal. It is reported that these services are evaluating whether users are allowed to use bitcoin on their respective platforms
2. Litecoin
litecoin is based on bitcoin protocol, but supports faster transaction confirmation. The total number of litecains that can be mined in this system is 84 million, and the mining volume so far is about 20%. According to Charles Lee, the inventor of the virtual currency, the total value of litecoin currently in circulation is about $50 million. He said it was not clear that any physical merchants would accept payment from litecoin, but some host service providers had accepted the virtual currency
3. Freicoin
similar to litecoin, freicoin is also based on bitcoin protocol, but it is still in the early stage of development. According to mark friedenbach, one of the inventors of the virtual currency, the total number of freicoins that can be mined in the system is about 100 million, and the current mining volume is about 20%. The current number of concurrent users in freicoin network is about 100. At present, only a few small online merchants accept freicoin, and the inventor of the virtual currency is trying to promote it in a wider range
3. Ripple
ripple is not only a payment network, but also a virtual currency. The developer of ripple is opencoin, a Silicon Valley company. The company says its goal is to make ripple available to as many users as possible. Currently, the total number of ripples mined is about 100 billion, most of which are in the hands of opencoin. Chris Larsen, co-founder and CEO of opencoin, said opencoin is about to distribute 2000 ripples per user to about 40000 users, and plans to distribute about 50 billion ripples in the next few years. At present, consumers can register through ripple.com to get ripple wallet, and use the third-party service bitstamp to remit money from the bank account to use ripple wallet< 4. Amazon coins
Amazon is one of the few large technology companies that independently develop virtual currency. In most cases, the virtual currency of these companies can only be used on their respective websites. Amazon just launched the Amazon coins service in May, which can now be used to buy games, apps and other digital content on the kindle fire platform, as well as on app stores and websites. One dollar can buy 100 Amazon coins, while large purchases will get a discount. For example, 1000 Amazon coins are sold for $9.50
5. Well known virtual currency in China
there are many well-known virtual currencies in China, such as network currency of Internet company, Q currency of Tencent company, Q point and roll of Shanda company, u-coin meter ticket (used for igome game), chivalrous Yuanbao (used for chivalrous road game), grain silver (used for bixue Qingtian game), etc.
some shoudan teachers don't tell investors to control their positions, on the contrary, they let investors fight back. It can be very responsible to remind investors that the heavy position operation may make more money for one time, but in the end it will definitely be a dead end. Many people don't know what compulsory closing is even after the position explosion, because his teacher won't tell him at all. The first way analysts make money is through repeated trading by investors, so naturally, they hope that the more investors operate, the better. So there will be some teachers who constantly let you in, out, in and out. Frequent trading, resulting in the ultimate loss. In fact, this is what many friends call "single swipe". This kind of teacher is just pitching investors! If digital currency is cheated, it can be recovered by safeguarding rights. Don't worry.
you can get Guangcheng watch bank and ask Shifu to help you find out what the problem is
many people think that a watch is not waterproof. Why does it get into the water? The higher the waterproof coefficient, the more difficult it is to get into the water, but it doesn't mean it won't get into the water. Many people have misunderstood it. If you wear a watch for two years, and don't go for maintenance, it's normal to get into the water when you take a bath or swim, Because the waterproof rubber ring of our watch will oxidize slowly with time. Usually, if the watch is not maintained, the waterproof ring is not replaced, and the waterproof test has not been done, the waterproof performance of the watch will graally weaken
if you wear a watch for a long time, such as bathing, diving and swimming, it is recommended to test the waterproof performance of the watch every year.
