Talk about your understanding of bitcoin and virtual currency
The earliest is a kind of network virtual currency. 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. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar
< H2 > extended information:bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin
because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".

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.
from q-coin and counting roll used to buy props to bitcoin which can be exchanged with us dollar and euro today. It shows that the utilization rate and universality of virtual currency are graally increasing. I think this kind of virtual currency has both advantages and disadvantages. Virtual currency makes up for the deficiency of currency, but it will not replace the real currency
1. Security of virtual currency. The day before yesterday, a bitcoin trading platform headquartered in Japan was favored by many people. However, e to the loss of 750000 bitcoins from customers and 100000 bitcoins of its own, the company had to file for bankruptcy protection. This fully shows that the security of virtual currency is difficult to guarantee
2. The use of money cannot be regulated. The problem is that there is no manager similar to the central bank. Due to the strong anonymity, it is easy to be used for illegal transactions such as speculation and drugs, as well as money laundering. Without the network of financial institutions, it is difficult to grasp their liquidity, which will bring difficulties to taxation
although it has many uncertainties, virtual currency is very effective and reliable to a certain extent
1. The possibility of inflation of virtual currency is small, and it is not affected by policy. Avoiding the influence of the central government on finance, virtual currency can prove the stability of its value because of its limited circulation. It will not raise prices and lower the value of money because of the increase of money supply
2. Strong circulation. People can use bitcoin to trade anywhere in the world where there are networks and computers, which is very convenient
it not only saves time, but also saves a lot of transaction costs
after comparison, I think that the virtual currency will be saturated and will not pose a threat to the real currency. On the one hand, in the backward regions and countries, they rely more on currency, resulting in a gap with the developed regions. On the other hand, with the development of network technology, the security of virtual currency will be more and more difficult to determine. It is also very difficult for people to use a lot of money in the form of virtual currency in huge investment. Especially in a country with traditional culture such as China, people are more confident that they will hand over their property to the financial instry such as banks, rather than in the online world like flowers in the mirror< There is no comparability between bitcoin and stock. Stock is people's profit expectation for a company. For example, a company constantly proces new procts to increase its wealth. People can obtain wealth growth with the company by holding shares of the company. And the stock is an investment proct, without monetary attribute, it is impossible to say how much ICBC stock an iPad is worth. On the contrary, like bitcoin, the stock can be converted into legal currency through the exchange to purchase the iPad. Similarly, in the so-called companies that accept bitcoin payment, all of them are marked with legal currency. They accept bitcoin through a third-party company, and finally receive legal currency from a third-party company
therefore, stock is people's expectation for the future development of a company, and it is an investment proct. There is no comparison with bitcoin, which clamors to become a currency
2. The existence of money lies in circulation and pricing. A thing that has been reced to a speculative tool since its existence, expecting appreciation and redistributing wealth can not become money
3. As cndx God said, bitcoin will have 2.0 in the future, which will be seamlessly connected with 1.0. That's funny. Why should the inventor of 2.0 connect with 1.0? Just as bitcoin does not connect with RMB, it is another opportunity for wealth redistribution
4. The existence of virtual currency can only meet the money laundering needs of a small number of people, so there is a market. For example, if someone wants to launder US $1 million recently, the ratio of bitcoin to legal currency will change, which is also in line with the market rules. Of course, money laundering is risky. If you buy one million dollars of bitcoin, you will hold it forever without losing any money
5. My legal currency is in the bank. If I lose it, I can still get it back with my ID card. Is my bitcoin password gone? Who should I go to
6. The currency expected by cndx will not be lost. At most, it will play in a certain circle just like Q currency
7. This thing is the proct of anarchism. If you want to embody value, you can only do it without government. The distribution of wealth depends on power and blood. For example, if you hold 10000 bitcoins, ZF says not to use them, and you say I'll use them. Bang, you're dead. Oh, bitcoin has appreciated again, because the total amount is less than 10000.
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system. From this point of view, the potential of bitcoin is unlimited, enough to subvert the current financial instry
in China, bitcoin is defined as a special Internet commodity by the central bank, and people can buy and sell it freely at their own risk. Most of the major countries in the world have adopted a cold treatment attitude towards the special currency, which is neither negative nor positive and ambiguous. Germany is the friendliest of bitcoin. Last August, Germany defined bitcoin as a private unit of account (private currency). Australia, the United States, Canada and other countries regard bitcoin as an asset that needs to be taxed. Of course, the attitude of each state and department in the United States is also different. Sometimes, the attitude of the same department and state is also contradictory.
Decentralization: bitcoin is the first distributed virtual currency. 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

cross platform Mining: users can explore the computing power of different hardware on many platforms
bitcoin is the earliest cryptocurrency and the largest cryptocurrency so far. Bitcoin and blockchain were born at the same time. Like gold, the issuance and launch of bitcoin can not be broken through, and the total amount is up to 21 million. Gold is not issued by any country, it is issued by nature, so most people agree that gold is money
bitcoin is as like as two peas in gold, and how much is the bit currency? Let's take a look at the enring joke in the coin circle. Nine years ago, a programmer traded 10000 bitcoins for two pizzas. This is the first transaction of bitcoin. It also shows that bitcoin can circulate like money. This is the embodiment of the value of bitcoin
if blockchain is compared to flour, then bitcoin is steamed bread made of flour. Flour can also be used to make rolls, pancakes, etc., but the first food made of flour is steamed bread
similarly, bitcoin is the first application of blockchain technology. However, in addition to bitcoin, blockchain technology itself can also be used for many purposes, such as blockchain can effectively solve identity forgery and data tampering of central supervision system
