As of July 24, 2020, the state has not issued any laws to prove that bitcoin mining machine is illegal
bitcoin mining machine is one of the ways to obtain bitcoin. Bitcoin is a kind of network virtual currency proced by open source P2P software
it doesn't rely on the issuance of specific monetary institutions, and 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
extended data
the issue and transaction of bitcoin are realized by mining, and it is cast at a certain but slowing rate. Each new block is accompanied by a certain number of new bitcoin from scratch, which is used as a coinbase transaction to reward the miners who find the block
the reward for each block is not fixed. For every 210000 blocks mined, it takes about four years, and the currency issuance rate is reced by 50%. In the first four years of bitcoin's operation, each block created 50 new bitcoins. Each block creates 12.5 new bitcoins. In addition to the block award, the miner will receive a handling fee for all transactions within the block<

there is a good book: "Du, the future starts here." Dong Li, Qing Publishing House
I just don't know that it's not convenient for you to buy it
the following is for reference only
in recent years, no city in the world has attracted as much attention as Du. After all, Du is only one of the weakest countries in the world in terms of population and economy. So, why can such a tiny place attract the attention of the whole world
anyone who has been to Du knows the answer. The small emirate along the Persian Gulf is right at the heart of the so-called "Renaissance" of Arab architecture, culture and commerce. Although the Middle East is fortunate to be one of the richest regions in the world thanks to oil, it has long lacked a major metropolis capable of becoming a financial, cultural, environmental and service center. For this reason, Sheik Mohammad Maktoum, the ambitious, wise and decisive chief of Du, has been striving to build Du into a business, tourism and entertainment center in the whole Middle East for the past five years
although its local population is only over 1 million, it can't be compared with a country with a large population such as China. However, it can gather 1.5 billion people in a few hours' flight time. It is based on this consideration that Sheikh Muhammad has the confidence to build Du into a leading metropolis in the "World Center". The plan is simple and arous. The 58 year old, visionary Du chief is working to transform the vast desert into a modern metropolis with world-class architecture and talent
in the past five years, Du has become the fastest growing tourist attraction in the world, and five-star hotels have sprung up, which is enough to make any European and American city envy itself. Its landmark, Burj Al Arab, is the only seven star hotel in the world. In addition, the Burj Du, the world's first building, will soon be completed and will have the world's largest shopping center. At present, the world's two largest shopping centers are in China - Dongguan South China shopping mall and Beijing Jinyuan times shopping mall. So, how can Du, a small emirate, bring in the world's best architects? An important factor is that the "9 / 11" terrorist attack on the world trade center in the United States made all Arabs feel uneasy and worried. Many people think that this incident has aroused hatred in the west, and sooner or later it will be tit for tat. What Sheikh Muhammad saw was a great opportunity to build a resort where Arabs could enjoy themselves in their own way. Facts proved that his decision was right. Now, these people rush to Du for holidays and shopping, and of course, they bring their money to Du. Almost all international luxury brands have stores in Du
Du is not only a resort for shopping, but also a paradise for living. Now, there are 250000 apartments built or under construction in Du. Once they are listed, they will soon be sold out by the Arab Middle Class in the surrounding areas (such as Saudi Arabia, Egypt, Iran, etc.). It is not only Arabs who come to Du to invest, but also Europeans led by British, Indians and Pakistanis. In addition, many Russian tycoons often come to Du to buy houses and shop. The shrewd Du changed the law to allow foreigners to own real estate in Du, which greatly increased the demand for real estate
in this scorching desert city, there is no room for "runner up" to survive. As a result, a variety of huge projects followed, and the world's first-class architectural and Engineering Masters finally found their place. The mall of the Emirates, which was built by us, has the largest indoor skiing center in the world. You can imagine how attractive it is when you have this view in a desert. Now people's attention is focused on the world's largest artificial island - the palm, which is shaped like a huge palm tree and can be seen clearly from space“ Nakheel, the founder of "Palm Island", a state-owned enterprise in Du, is watching the old rival Emaar's Du building "grow higher and higher" day by day, and then announcing the official change of ownership of the title of "world's first building". The Du Tower will be completed in another year, but no one knows how high it is until it is completed. It's a secret, and Emaar keeps it a secret. So Nakheel is patiently waiting for the height of the Du Tower to be finally revealed before announcing that he will build the next world's tallest building
is there a bubble in Du's prosperity? Today, the proportion of non oil instry in GDP is as high as 95%, while it was only 46% in the 1970s, which fully shows that Du is developing rapidly into a modern economic power based on services. To this end, many larger and more developed countries have sent government delegation to visit Du to explore the secret of its success. In fact, however, there is no secret. Du has a wise and strong leader who can make decisions and change strategies quickly. There is no bureaucratic government that hinders business growth, and because of the tax exemption, companies don't have to waste time hiding their actual profits. In addition, its planning system is also very flexible. As long as investors have good ideas, they can get permission to start the project immediately. For example, it took only three years from planning, construction to the final opening of the shopping mall in the United Arab Emirates. In a developed country, we need at least five years or more. In urban competition, it is also a huge advantage to be able to implement the project so quickly. Now, many Middle East countries such as Bahrain, Abu Dhabi and Oman are ing Du's strategy and success factors. But Sheikh Muhammad is not so timid, but actively planning larger projects. For example, the Du government recently announced that it will spend US $54 billion to build a large entertainment city called "Al bawadi" on the edge of Du. The entertainment city will be distributed along a 10 km long road in a strip shape. On both sides of the road, there are not only 51 theme hotels (60000 rooms), but also the world's largest shopping area with an area six times that of South China shopping city. When completed, it will replace Las Vegas and Macao as the world's largest entertainment city. Its "Asia Asia" Hotel, with 6000 rooms, is also the largest in the world. But it's not over. Sheikh Muhammad said he is currently considering two other large projects, but did not disclose the details. What could be bigger and better than all this in Du? We can only guess. But one thing is certain, that is, we are witnessing the birth and growth of an international metropolis. In human history, only a few people have the honor to be witnesses of Du's development.
