1. 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.
2. 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
3. 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
4. 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
5. There are several phenomena or degrees of water entering the watch:
(1) there is fog in the watch glass, and sometimes there is no, especially when the temperature difference is large
(2) there is water condensation in the watch glass
(3) a lot of water droplets can be seen on the watch glass and dial
the watch maintenance center is located in room 3003, 30 / F, Tianjin International Financial Center building, Heping District, Tianjin city
if the watch is found to be flooded, the most urgent thing is to send the watch to the clock repair shop for drying as soon as possible, and wash the oil if the water is serious. Don't leave it alone. If you don't repair it in time, the water will make the steel parts in the watch movement rusty. Once the small watch parts rust, they usually need to be replaced, and the future repair cost will be great. You should know that the damage of water on the watch is "catastrophic". In addition to the movement parts of a watch, long-term contact with water vapor will also cause the dial and needle of the watch to change color, blister and rust. Here, I would like to remind you that if it is a watch with water intrusion repeatedly, you need to pay special attention when wearing it
it's a serious thing for watches to get water, especially for some high-end mechanical watches. If they are not repaired in time, the water will make the steel parts in the movement of the watch rusty. Once the small parts of the watch get rusty, they usually need to be replaced, and the repair cost will be very high in the future. We should know that the damage of water to the watch is "catastrophic". In addition to the movement parts, long-term contact with water vapor will also make the dial and needle of the watch change color, blister and rust.
6. This is a gimmick of virtual currency. Don't take it seriously. It's a currency not recognized by the state
7. It is recommended that you can open the warranty sheet attached to the purchase of the watch. Under normal circumstances, the warranty sheet will have the service address, or you can find a regular watch Service Center for inspection and repair
within the warranty period, you can get the counter
generally, it is better to repair in Shanghai and Beijing
8. Where to buy it? There are not many stores in China. Anyway, they will send it to a special maintenance center in China or a foreign headquarters for you. If the cost is not enough, you may pay most of it
9. I'm crazy about money
