The advantages of digital currency over traditional currency are
digital currency is characterized by low transaction cost, fast transaction speed and high anonymity
1, low transaction cost
compared with traditional bank transfer, remittance and other ways, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment that provides high handling charges to payment service providers
2. Fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization. It does not need any centralized organization similar to the clearing center to process data, and the transaction processing speed is faster
3. High anonymity
in addition to the point-to-point transaction without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote point-to-point payment, and it does not need any trusted third party as intermediary, Both sides of the transaction can complete the transaction in a completely unfamiliar situation without mutual trust, so they have higher anonymity, which can protect the privacy of traders. But at the same time, it also creates convenience for cyber crime, which is easy to be used by money laundering and other criminal activities

the impact of digital currency:
digital currency is a double-edged sword. On the one hand, the blockchain Technology it relies on realizes decentralization and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular
On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stabilitybitcoin is an electronic money system with a fixed total amount, which is established on the global decentralized network system and issued without the participation of central banks and third-party institutions. Bitcoin has the characteristics of payment system and currency at the same time. Global network nodes are maintaining the bitcoin network all day<

different from traditional currency, bitcoin's operation mechanism does not rely on the support or credit guarantee of central bank, government and enterprise, but on the network agreement reached with seed files in the network, which is a decentralized and self-improvement monetary system, Theoretically, it ensures that no one, institution or government can control the total amount of bitcoin or create inflation. Its total amount of money graally increased at the designed rate, and the increase rate graally slowed down, and finally reached the limit of 21 million in 2140<

bitcoin is based on a set of cipher codes and generated by complex algorithms. This rule is not interfered by any indivial or organization and is decentralized; Anyone can download and run the bitcoin client to participate in the proction of bitcoin; Bitcoin uses electronic signature to realize circulation, and checks repeated consumption through P2P distributed network. The generation and consumption of each bitcoin will be recorded through the P2P distributed network and informed to the whole network. There is no possibility of forgery. 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<

the difference between bitcoin and bitcoin
it should be noted that
in English, the words bitcoin and bitcoin represent two concepts of payment network and monetary unit
bitcoin starting with capital B represents bitcoin network system or bitcoin network protocol, which is a payment system based on decentralized network
you can simply understand bitcoin as a public accounting system built on the Internet and not manipulated by any third party. Bitcoin, which starts with lowercase B, refers to the digital currency (e-money, e-cash, cryptocurrency) built on bitcoin network. Bitcoin is the payment accounting unit built in bitcoin payment system. We call bitcoin the network system that proces bitcoin<
in Chinese, bitcoin and bitcoin are both called bitcoin without distinction in many places
its main features are as follows:
1. 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< Bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership
private key is required to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost
bitcoin can be remitted free of charge, but in the end, a small transaction fee will be charged for each transaction to ensure faster transaction execution
5. No hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay<

it will take some time to protect privacy when using bitcoin. All bitcoin transactions are publicly and permanently stored in the network, which means that anyone can view the balance and transaction records in any bitcoin address. Unless the bitcoin holder discloses personal information ring the transaction, the bitcoin address will not be associated with the real identity of the bitcoin holder. This is why it is recommended that bitcoin holders use multiple bitcoin addresses; In fact, you should create a new address each time to receive bitcoin. This is especially important when using bitcoin in public places, such as on websites. In addition, you can also consider using tools like tor to hide your IP address from being recorded.

7. Bitcoin is still experimental
bitcoin is an experimental new currency in active development. Although its experimentality is diminishing with its increasing usage, remember that bitcoin is a new invention, exploring ideas that have never been tried before, so no one can predict the future of bitcoin.
Caixin reporter: on January 20, the people's Bank of China held a seminar on digital currency and proposed to strive for the early launch of the digital currency issued by the central bank. What is the reason for this< In fact, the central bank has been studying digital currency for a long time. From the perspective of historical development trend, money has always evolved with the development of technological progress and economic activities. From the early physical money, commodity money to the later credit money, it is a natural choice to adapt to the development of human commercial society. As the currency of the previous generation, paper money has low technology content. From the perspective of safety and cost, it is the general trend to be replaced by new technology and new procts. In particular, with the development of the Internet and the great changes in payment methods all over the world, the establishment of digital currency issuance and circulation system is very necessary for the construction of financial infrastructure and the promotion of economic quality, efficiency and upgrading
how to replace it? There are several ideas: one is to imitate paper money. For example, transactions between paper money are anonymous, and digital currency also wants to be anonymous, which leads to its technology choice. But the reason why banknotes are anonymous is not designed intentionally at first, but no other technology can guarantee the convenience of a large number of small transactions. Of course, some people think that anonymity is better for future digital currency transactions, because assuming that the government may make mistakes, the privacy of private wealth and the use of wealth should be absolutely protected
from the perspective of the central bank, the future digital currency should try its best to protect private privacy, but social security and order are also important. In case of criminal problems, it is necessary to retain the necessary verification means, that is to say, it is necessary to find a balance between protecting privacy and cracking down on criminal activities. The mastery of the balance between these two motivations also makes the tendency of technology choice different<
Caixin: what are the central bank's ideas on the issue and management of digital currency? What's the difference between digital currency and digital currency spontaneously appearing in the current market< / > Zhou Xiaochuan: at present, what many countries in the world recognize is the framework of digital or electronic money dominated by the central bank, which may be different from that of the people
when the central bank issues digital currency, it mainly embodies the following principles: first, it provides convenience and security. Second, as mentioned above, we should balance the protection of privacy with the maintenance of social order and the fight against illegal and criminal acts, especially for money laundering, terrorism and other criminal acts. Third, it should be concive to the effective operation and transmission of monetary policy. The fourth is to retain the control of currency sovereignty. Digital currency is freely convertible and controllable. Therefore, we believe that digital currency as legal tender must be issued by the central bank. The issue, circulation and transaction of digital currency should follow the idea of integration of traditional currency and digital currency, and implement the same principle of management
Caixin: is there a timetable for the launch of digital currency? Is it going to replace paper money in the end
Zhou Xiaochuan: we can't say the timetable of digital currency yet. China has a large population and a large volume. For example, a new version of RMB can be changed in a few months for small countries, but it will take about 10 years for China. Therefore, digital currency and cash will be parallel and graally replaced for quite a long time. In the later stage, the transaction cost of cash will graally rise. For example, in the past, banks were asked to count a large number of coins, and there was no charge for them. Later, they may need to charge. With the incentive mechanism, people will naturally use more digital currency, but the two will still co deposit in the longer term< However, there are many other applications of virtual currency. For example, the European crowdfunding platform uses blockchain technology to combine digital currency with real assets.
even if it's live broadcasting, it's no problem. Live broadcasting is mainly about processor and memory. You can satisfy it, but you need to ensure the network speed
bitcoin, as a kind of network digital currency, can be said to be liked by many people, because for many people, bitcoin will bring high profits to themselves, but we will crack down on such things, and such procts will be suspected of illegal fund-raising or money laundering to a large extent
it is very difficult to supervise bitcoin, because bitcoin is a kind of virtual network digital currency, so it will be very difficult to manage the behavior of many people's speculation on bitcoin. Although we often stop such behavior, people's interest is very big, In many cases, it can be said that it is because of their own interests that they will suffer losses{ RRRRR}
you must pay attention to your own safety when carrying out online trading, and do not believe in any online investment and online stock speculation
the United States is the country with the most coal in the world, because there are many mountains with a lot of coal reserves in their country for example, these mountains with rich coal deposits have been extending from Canada to Alabama for more than 3200 kilometers. It's hard to imagine that such a long mountain line is rich in coal, accounting for 27.6% of the world's coal, so the United States is the country with the largest coal reserves{ RRRRR}
even with such abundant coal resources, we should make rational use of them and maximize their utilization of course, the surrounding ecological environment should also be taken into account, so as not to cause serious environmental problems. In fact, many animals and plants around these mining areas have been greatly damaged
