What's wrong with mining
mining: that is, bitcoin mining, is a process of using computer hardware to calculate the location of bitcoin and obtain it
Bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on
extended data:
mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, system risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners

3, users use personal computer to download software, and then run specific algorithms. After communicating with remote server, they can get corresponding bitcoin, which is one of the ways to get bitcoin. Ordinary graphics cards don't need to try, and electricity charges are not enough. Master Lu has bitcoin test, which can see how long it takes for your computer to dig a bitcoin
Mining means that users download software from personal computers and then run specific algorithms to get corresponding bitcoin after communicating with remote servers
bitcoin is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods
bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware, and the miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by the miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

extended materials:
the founder of bitcoin:
on November 1, 2008, a person who called himself Satoshi Nakamoto posted a research statement on a secret cryptography review group, stating his new idea of e-money - bitcoin came out and the first transaction of bitcoin was completed
bitcoin has got rid of the constraints of third-party organizations with the help of Internet, which Nakamoto calls "regional chain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money
trading is also extended on this network. The computer running this software can solve the problem of irreversible code, which contains several trading data
the first "miner" to deal with the problem will be rewarded with 50 bitcoin, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes
in 2009, Nakamoto designed a 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
Bitcoin mining is a process of using computer hardware to calculate transaction confirmation and improve security. Bitcoin is a reward for miners to calculate and confirm
bitcoin also has a hype mode. Similar to bitcoin, there are also flow ores. Flow ores also have ways of trading and speculation, but the mining principle of flow ores is different from bitcoin. Flow ores mainly collect the idle bandwidth of miners and give them rewards
in fact, the blockchain technology adopted by bitcoin is more valuable than itself. This is a new way of information storage. The data is stored in all devices connected to the network. When new devices join, the information will be updated automatically, and all devices have the right to read the information
to understand the significance of bitcoin from the perspective of currency, we need to understand the currency itself first, and then compare it with the characteristics of bitcoin. After comparison, I think that bitcoin is a very high-quality currency, but some people don't think it is. They mainly question the formation mechanism of bitcoin and the lack of national credit as guarantee. They think its foundation is relatively weak
at present, there are quite a lot of arguments about bitcoin in academic circles. For example, if the total amount of bitcoin is certain, then whether it will cause deflation or inflation has different views. I think it's deflation, and the value of bitcoin will be higher and higher
at present, bitcoin still means a little bit of a safe haven currency. When the news of brexit came out, the transaction price of bitcoin rose by 20% - 30% to about 4500 yuan / piece
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. 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 21 million
the concept of bitcoin was first proposed by Nakamoto in 2009. Bitcoin, also known as bitcoin, is an open source software designed and released according to the idea of Nakamoto Tsung, and a P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution. It uses distributed databases throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation
Mining bitcoin is also called mining. 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
in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
extended data:
shortcomings
first, the 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
Second, the transaction confirmation time is long. 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 Thirdly, 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 Fourthly, 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 worthlessmountaineers can choose to take the cable car, or walk up the path and steps beside the cable car track, enjoy the exotic flowers and plants hidden in the tropical rain forest of Shengqi mountain, and enjoy the magnificent scenery of George city along the way; The air on the mountain is fresh and the scenery is panoramic. You can also visit Penang Bird Park on the mountain. The cable car was opened to traffic in 1923
Penang botanical garden was established by British colony in 1884, mainly for the purpose of planting tropical economic crops and collecting tropical plant species. The garden covers an area of 30 hectares. During the waterfall period, the boundary is surrounded by primitive tropical rain forest, forming a botanical garden with both English garden and Penang local scenery. The wild monkeys in the garden are another feature
the blissful temple, built on the mountain and divided into three layers, is known as one of the most magnificent Buddhist temples in Southeast Asia. It is a temple with Chinese, Thai and Burmese architectural styles
the Wofo temple, built in the 19th century, is located on the Che Shui Road. The temple combines the architectural styles of China, Thailand and Myanmar, and is gorgeous and exquisitely carved. A 33 meter long reclining Buddha statue is worshipped in the temple, ranking the third largest in the world, only next to the Giant Buddha in Myanmar and Thailand
the snake temple in Penang was built in 1873. It used to be a ancestral temple of qingshuishizu, named "qingyunyan". The name of snake temple is that after the temple was built, several green snakes came to live in it. On the birthday of the founder of Qingshui, countless green snakes swarmed into the temple from the back mountain, which became a great spectacle. Therefore, the "snake temple" was famous all over the world. Snake temple is 3.2km away from Penang International Airport
Longshan Hall of Qiu company is the ancestral hall of Qiu family. It was built at the end of the 19th century near Dashi street, and the building is still in good condition. The building is an ancient Chinese style, imitating the palace of the Qing Dynasty. The ancestral hall is divided into "Zhengshun Palace" in the center and "Ford Palace" and "Yugu Palace" on both sides. Qiu's ancestral hall, also known as "Longshan hall", is divided into three parts: the hall in the middle, which is dedicated to the Great Buddha, the tablet of Qiu's past dynasties on the right, and the hall on the left, which is dedicated to the great uncle. The bottom floor of the temple is specially used for clan renting and wedding celebrations, and there is a stage opposite the ancestral hall for gods to perform dramas
Fort Cornwallis, located in the northeast of Penang Island, is the place where French Wright landed in 1786. Originally made of wood, the castle was later rebuilt by local prisoners carrying stones to guard Haikou. There are still several cannons on the castle
resort beach: the beaches in Penang are mainly distributed in the north, from tanjungwuya to Ba dinyi. There are 11 kilometers of white beaches, which can enjoy the fun of playing with the tide all year round. Danrong Wuya is known as & quot; The Cape of flowers
exploring fuluoshanbei is the tourist center of fuluoshanbei District, which mainly provides tourism consultation and tourism related services for tourists in Southwest China. The center also provides foot car rental and seasonal free tour guide services“ "Explore the back of the mountain" is located in yayibudai

Penang is one of the 10 must visit islands in the world recommended by Yahoo travel website, ranking 8th, and the only island on the list of Malaysia< A hundred years ago, Zhang Bishi's mansion, commonly known as "Blue House", was restored as an exhibition hall / hotel in 1995. The building is very spectacular, ingenious fusion of Chinese and Western cultural style, impressive. If you have money, you can consider staying for one night
the magnificent eaves of Longshan hall, together with the stage, zongyisuo and the surrounding row houses, form the site of Qiu company. It's like a labyrinth. The location is secret. When you see the eaves, you just can't find the entrance. It's very exciting. The most exquisite ancestral hall in Southeast Asia is being restored, and the project will be completed and opened before the lunar new year
covered with moss marks and mottled vicissitudes, the street house before the war has taken on its true colors. Penang has one-third of the pre war buildings in Malaysia
in the "Blue House" (former residence of Zhang Bishi) in the sun, time seems to stop turning

Mr. Buffett said; The United States will never default on its debt because it prints dollars It's too confident for Buffett to say that. Let's talk about my personal opinion
the United States will never default on its debts
the United States is a country with low credit rating. I believe many people do not agree with the statement that the United States will never default on its debts. Here are some examples to demonstrate Warren Buffett's view:
1; The US wants to freeze China's national debt If the United States can say such a thing, it proves that there is such an idea in its heart. Since it has such an idea in its heart, it is obvious that the United States is a country that dares to breach the contract, and Warren Buffett's view is a slap in the face
the United States will never default on its debt. Will the United States print US dollars
through the above analysis and data, we can see that Warren Buffett's statement is too confident, too trusting in the United States, and extremely irresponsible
take Mr. Buffett as an example. His words and deeds are different. He said that he would not short US stocks. As a result, he still short US stocks. There are many losses in aviation stocks, and Mr. Buffett suffered heavy losses. This also proves that Mr. Buffett's statement is not reliable
based on the above analysis, we can draw a clear conclusion that the United States will never default on its debt, which is not credible. The United States, in particular, is a country with a very low degree of credit, which turns its face faster than turning a book. So when you see this view, you can laugh it off
