Laoqi mining
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
the mine is on the top right of the map of beech province. Press tab to see a small white sign on the top right. Run that way.
for example, the plug-in with timely rain or similar plug-in with miner function can automatically screen the type and purity of the mine, and the mine you don't need will be automatically discarded. You can just watch smoking. The plug-in is fully automatic, and the setting is very simple. You can see it at a glance
another is offline plug-ins, such as the offline version of timely rain, or similar plug-ins. Similar to above, but offline. You can do something else at the same time. One of them digs automatically.
Since Gengsheng, ASUS and Qicaihong's RTX 2070 super graphics cards have more than one model, we will choose Gengsheng's Zhuifeng series, ASUS's Raptor series, Qicaihong's ultra series, and RTX Super Series graphics cards which also adopt NVIDIA Turing architecture core. How much difference will the actual performance be? Let's start right away
at 2K resolution, ASUS Rog RTX 2070 super Raptor is the first with 109 high frame rate, which is 2 frames higher than Gengsheng and 4 frames higher than Qicaihong. The actual performance gap is only about 1%
however, with the highest image quality of 4K, Gengsheng RTX 2070 super overtakes ASUS Rog RTX 2070 super Raptor and Qicaihong RTX 2070 super ultraoc again, taking the lead with an average frame of 57
in the actual test of the game, there may be 3% error, but from the current test results, it can be concluded that the frequency of the graphics card can not represent the actual performance of the graphics card itself. Although the core frequency of Gengsheng RTX 2070 super is not as high as ASUS and Qicaihong, it has achieved good results in the actual test
summary
in the actual test part of 3dmark and the game, it can be seen that the comprehensive performance of Gengsheng RTX 2070 super is better than ASUS Rog RTX 2070 super Raptor, but in the overall data, Gengsheng RTX 2070 super has the advantage. Compared with the three graphics cards, the difference is only about 1% from the comprehensive data
after a series of tests, the conclusion is that ASUS Rog RTX 2070 super Raptor is about 1% ahead of the other two graphics cards in performance, while the RTX 2070 super is nearly 10 ℃ ahead of the other two graphics cards in temperature. In terms of price, ASUS Rog is 1000 yuan higher than Qicaihong and Gengsheng. Is it really necessary for players to spend nearly 1000 yuan more for 1% performance? If you choose from the above three graphics cards, you will recommend purchasing Gengsheng RTX 2070 super
before the 1970s, the price of gold was basically decided by governments or central banks, and the international price of gold was relatively stable. In the early 1970s, the gold price was no longer directly linked to the US dollar, the gold price was graally marketized, and the factors influencing the gold price were increasing. Specifically, it can be divided into the following aspects:
international gold price pricing mechanism
London gold market has a long history. As early as the early 19th century, London was the world's gold refining, sales and exchange center. In 1919, the London gold market began to implement the daily pricing system, twice a day. The price is the most important gold price in the world, which has affected the gold market transactions in New York and Hong Kong. The gold market prices of many countries and regions are based on the London gold price, and then fluctuate up and down according to their respective supply and demand. At the same time, the London gold price is also the benchmark price for many contracts involving gold trading
the pricing of gold in London is at & quot; Golden House & quot Gold room) in the office of the company's headquarters in central London. Since September 12, 1919, the representatives of the five big gold banks in London met for the first time; Golden House;, It began to set the daily price of gold in the London gold market, and this system continues to this day. The five gold banks set gold prices twice a day, at 10:30 a.m. and 3:00 p.m. By the Rothschild company as the pricing host, generally before the pricing, the market trading stops for a moment. At this time, the gold dealers will suspend the quotation first, and the chief representative of Rothschild company will set an appropriate opening price according to the New York gold market price after the closing of London market the night before and the Hong Kong gold market price in the morning of that day. Representatives of the other four companies sat in & quot; Golden House & quot; In the next four weeks, the opening price will be quoted to the trading room of each company immediately, and the trading room of each company will trade according to this price immediately, and the latest gold price will be transmitted to its customers by telephone or telex, and the price will be presented in the computer terminal of each trading room through Reuters. When each representative receives the order business, they will add all the transaction orders together to see whether they are buying more or selling more or offsetting the sales, and then tell the data information to the chief representative of Rocher in simple jargon to adjust the price. If the opening price is too high and there is no buyer in the market, the chief representative will rece the price of gold; If the opening price is too low, it will raise the price of gold until there is a seller. Pricing transactions are based on such a relationship between supply and demand to set a new price. At the same time, in & quot; Golden House & quot; There is a small British flag on the table of each company representative, which was put up at the beginning. In the process of gold pricing, as long as there is a company's flag standing on the table, it means that there are new orders for gold transactions in the market, and the chief representative of Rothschild can not end the pricing. Only wait until & quot; Golden House & quot; The five small flags inside are put down together, which means that there are no new buyers and sellers in the market. Only when the order business is completed will the representative of Rocher announce the end of the transaction. The final price of the pricing is the transaction price. The time of pricing depends on the supply and demand of the market, which can be as short as one minute and as long as about one hour. After that, the new price will soon be passed on to traders all over the world
the importance of London gold price is closely related to the core position of London gold market in world gold trading. London monopolized all the gold sales of South Africa, the world's largest gold procer, so that most of the gold supply in the world gold market was traded through London gold market. Moreover, the five largest gold merchants in London gold market are also famous in the world, and have extensive contacts with many gold mines and gold merchants in the world; The five major gold merchants have many subordinate companies, which are in contact with many stores and gold customers. This scope not only involves London gold market, but also extends to the whole world. In addition, in the pricing process, gold merchants provide customers with a single transaction price, no bid ask price difference, and the price is reasonable. Therefore, many people like to trade when pricing. Therefore, in & quot; Golden House & quot; In this paper, the five major gold traders, representing almost all the gold traders in the world, including gold suppliers, gold demanders and speculators, decide the most reasonable price for both buyers and sellers in the market, and the whole pricing process is completely open. As a result, customers who trade at the time of pricing can definitely know that the transaction price is reasonable. Because of the above characteristics of London gold price, London gold market price has become the most important gold price in the world
four major pricing banks

Bank of Nova Scotia - Scotia mocata
Deutsche Bank; HSBC usx
Credit Suisse First Boston withdrew from its precious metal market making, financial derivatives, clearing and inventory businesses in London, New York and Sydney on October 12 this year. The exit of Credit Suisse provides an opportunity for gold procers to enter the London pricing Committee. At present, many gold mining companies want to buy the seat.
supply factors
(1) gold stock on the earth: there are about 137400 tons of gold in the world, and the stock of gold on the ground is still growing at a rate of about 2% every year
(2) annual supply and demand: the annual supply and demand of gold is about 4200 tons, and the annual new output of gold accounts for 62% of the annual supply
(3) new cost of gold mining: the average total cost of gold mining is about 260 US dollars / ounce. Due to the development of mining technology, the cost of gold development has continued to decline in the past 20 years< (4) political, military and economic changes in gold procing countries: no doubt any political and military turbulence in these countries will directly affect the amount of gold proced in the country, and then affect the world's gold supply< (5) the central bank's gold selling: the central bank is the largest holder of gold in the world. In 1969, the official gold reserve was 36458 tons, accounting for 42.6% of the total surface gold stock at that time. In 1998, the official gold reserve was about 34000 tons, accounting for 24.1% of the total gold stock mined. According to the current proction capacity, this is equivalent to 13 years of world gold proction. Since the main use of gold has graally changed from important reserve assets to metal raw materials for jewelry proction, or to improve the national balance of payments, or to curb the international gold price, the central bank's gold reserves have declined greatly in both absolute and relative quantities in the past 30 years, and the decline in quantity mainly depends on the selling of gold reserves in the gold market. For example, the Bank of England's large-scale selling, the Swiss central bank and the International Monetary Fund are preparing to rece gold reserves, which have become the main reasons for the recent decline of gold prices in the international gold market.
