Bitcoin 010203

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. 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. 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. On January 8, 2021, the price of bitcoin exceeded $40000

warm tips: according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have legal compensation and mandatory monetary attributes, is not a real currency, does not have the same legal status as currency, and cannot and should not be used as currency in the market, Citizens' investment and transaction of virtual currency are not protected by law

3. Digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

4. The upper limit of bitcoin is 2100W, which is not up to the limit, but the cost is higher and higher. This kind of currency with a limit can slow down the depreciation of assets to a certain extent, just like gold. However, gold has value in use, while bitcoin is a virtual currency with no practical value, so this kind of currency is not as stable as gold (for example, bitcoin plummeted this time). Bitcoin can be split and purchased on some websites.

5.

According to the currency conversion ratio on October 22, 2020, one bitcoin = 86214.10 RMB

compared with fiat money, bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone can participate in the manufacture of bitcoin, and it can circulate all over the world. It can be bought and sold on any computer connected to the Internet. No matter where they are, anyone can dig, buy, sell or collect bitcoin, And in the transaction process, foreigners can not identify the user's identity information

whenever bitcoin comes into the view of mainstream media, mainstream media always ask some mainstream economists to analyze bitcoin. Earlier, these analyses focused on whether bitcoin was a scam. Now the analysis focuses on whether bitcoin can become the mainstream currency in the future. The focus of the debate is often on the deflationary nature of bitcoin

extended information:

purchase method:

users can buy bitcoin, at the same time, they can also use the computer to "mine" bitcoin according to the algorithm. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins

e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

6. No, I think it's a virtual currency. It has no limit. If it's a global virtual digital currency, it should be traded 24 hours a day, and there is no limit on the rise and fall.

7. There are many reasons why watches go fast. Generally, mechanical watches have errors. If you don't worry, you can go to the 30th floor of Tianjin International Financial Center in Heping District, where there is an elevator

8. Watches need to be repaired, and they need to be maintained even more. When we first entered the world of famous watches, we might only have one watch on hand at that time. Maintenance may have never been a problem for us at that time. Later, with the growing addiction to watches, the number of watches will increase from one to two, then to three, four or even five. On the other hand, the watch you get may be a brand new set of watches under protection, or a single watch without a card, or even an old watch or an antique watch. At this stage, watch repair and maintenance problems graally appear. Some players once said "maintenance is not very important, but very important". When I first heard this sentence, I couldn't feel it. Now, I pay more and more attention to the maintenance of watches. It's really very important, and even affects how you choose watches. Let's make an account. Rolex and omega watches, including watches of the same brand, have movement maintenance and washing oil. According to the complexity of movement (from three needles without calendar to timing movement), the price ranges from more than 2000 yuan to more than 5000 yuan (I don't know about Tourbillon and so on). In addition to washing oil, the most frequently changed parts are the sealing parts on the crown. Because the screw in lock handle is sure to wear out after only a few years, the customer service center generally recommends replacing it. The price I remember is 380 (if I pass the waterproof test ring the test, I won't replace it). You can add in the price yourself. When a watch is guaranteed for five years, there is no problem at all. However, when you have more and more watches, you will send them for insurance more and more times, and the probability of problems will be greater and greater (the watch will inevitably break, and I still have a certain brand of timepiece that has not been repaired). We will graally find that if we take turns to maintain many watches in our hands, we can buy another watch at a price (I have maintained and repaired several watches in the past, and some of them are not intended to be maintained). Tianjin world famous watch customer service center is located in room 3003, 30 / F, Tianjin International Financial Center building, 136 Chifeng Road
