Bitcoin McGonagall

1.

bitcoin is the first distributed virtual currency

to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client

after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

extended information:

as a virtual commodity, bitcoin itself has no national boundaries, and its operation mode is a "decentralized" monetary system, which is very convenient for one-time large transaction. Bitcoin is traded through the network, and the owner's identity is only in the form of a set of encrypted computer code

in the operation, input a digital address directly, click the mouse a few times, and wait for the confirmation of the transaction to complete the transaction. The network can only record which address a bitcoin was g up from and how it was transferred

however, the identity of the owners of these addresses can not be verified, which is just like when money goes to an ownerless bank account, the relevant transactions can easily be invisible from the perspective of government supervision, and it is difficult to be tracked or intercepted. In addition, bitcoin can evade the scrutiny of exchange control institutions required by normal cross-border remittance, and the transaction records will not be recorded by banks and other parties

naturally, the problem of reporting to relevant departments after the transaction exceeds a certain amount is avoided. Buy bitcoin with domestic currency, sell it on foreign trading platforms, and withdraw it in US dollars. Asset transfer can be completed in a few minutes

it is not difficult to open an overseas bank account related to bitcoin for foreign exchange, and the conversion is very convenient. Because of these characteristics, bitcoin has been chosen by criminal organizations

2. Bitcoin uses a number of technologies, more than one, mainly distributed P2P technology, cryptography technology and so on
it is recommended to search bitcoin white paper for more information.

3. What is bitcoin? What's the use of Internet? On the evening of the 12th, the computer blackmail worm named "eternal blue" broke out on a large scale in the world. It is said that "eternal blue" has spread to more than 100 countries, including Europe, the United States, China, etc. according to incomplete statistics, there are more than 1 million computers in the world, most of which are local area networks of universities and scientific research institutions. It is estimated that in the past 24 hours, about 150000 people have paid ransom to hackers through bitcoin trading platform. If this estimation is reliable, the amount of bitcoin that hackers have obtained is about 600 million yuan. If there is no accident, more people will pay ransom in the future. The amount of blackmail is estimated to be more than 10 billion! First of all, bitcoin does not belong to any country, indivial or organization. It is an uncontrolled and decentralized currency. Kun Peng made a search on it. In fact, bitcoin has been used as ransom in the early years. The method has not changed much. It's all encryption and blackmail. The person in charge of F-Secure, a network security company, once said that the encryption and blackmail software has become their biggest headache. Once the computer is infected, not only the hard disk drive is encrypted, but every file will be invaded. Although such incidents have emerged one after another in the past, it's only that they didn't have as much impact in the past as this one. Besides, people like to forget most, so they are not well known and it's normal. For example, around 2013, hackers began to extort bitcoin by illegally encrypting users' PC data and personal information. In 2014, an Australian executive was harassed by hackers after he paid $14000 worth of bitcoin ransom for malware under the pressure of online hackers. In 2015, hackers launched a third cyber attack on three Greek banks and demanded 20000 bitcoins (worth 7 million euros) as ransom from each of them. In 2015, the police department in tuxbury, Massachusetts, was attacked by hackers, resulting in the computer unable to log in. In order to prevent the loss of important data, the police station finally paid 500 bitcoin "ransom" as required by hackers. In 2016, a hacker hijacked the network of the Hollywood Presbyterian Memorial Medical Center through software, paralyzing the operation of the hospital. The hospital decided to pay 40 bitcoins, equivalent to about 17000 US dollars, as a "ransom" to the hacker Kunpeng believes that hackers choose bitcoin mainly because it has the characteristics of decentralization, globalization and anonymity like the Internet. Transferring bitcoin to the other side of the earth is as simple, low-cost and unlimited as sending e-mail. Bitcoin is therefore used in cross-border trade, payment, remittance and other fields. Moreover, bitcoin can be used to cash, which can be converted into the currency of most countries. Bitcoin investors generally believe that the reason why hackers choose bitcoin to pay ransom is that bitcoin not only has advantages over other traditional payment tools, but also is the best choice among other virtual currencies. Firstly, bitcoin has certain anonymity, which is convenient for hackers to hide their identities; Secondly, it is not subject to geographical restrictions and can collect money on a global scale; At the same time, bitcoin also has the characteristics of "decentralization", which allows hackers to automatically process the ransom of victims through programs. With the technical support of the network, the manufacture and issuance of bitcoin are not based on the trust of the central issuing institution, and the operations such as transfer and other transactions do not even need names. That is to say, to collect money with bitcoin, you don't need to open an account in the real name of a financial institution, and you don't need to go through any third-party institutions, such as the third-party payment that we use most at present. You just need to download and register an independent bitcoin wallet. If what the criminal extorts this time is not bitcoin, US dollars or other currencies, and what the criminal gives is not a bitcoin wallet address, but a collection account of a bank, the hacker may have been locked or arrested before receiving the money. Now you know, anyway, I don't need bitcoin. Please pay more attention

In 2020, paxful immediately bought and sold cryptocurrency. According to the data, Nigeria's bitcurrency transaction volume was 1.1 million, ranking second in the world after the United States and Russia. However, according to relevant statistics, 32% of Nigerians use bitcoin to trade. According to the proportion of population, it is the number one in the world and should be the leader of bitcoin trading

at present, the Central Bank of Nigeria has realized the seriousness of the situation and asked all banks to close their bank accounts for illegal investment in bitcoin. This is the second time since 2017 that the central bank has directly intervened in bitcoin trading. People generally doubt the effectiveness of the policy, and believe that bitcoin trading may return to the door-to-door trading mode. In fact, after the first mock exam of the central bank's intervention policy, the total volume of transactions increased by 11.6%. p> It can be seen that Nigeria may be one of the world's bitcoin trading centers for a long time

5. Bitcoin is in an awkward position in both the monetary system and the capital market, and it always seems so nondescript. But that has changed. Investors have long been debating whether bitcoin can be defined as a commodity, as is the case with the CFTC. Fortunately, this question now has an answer. For the first time, bitcoin and other virtual currencies are reasonably defined as commodities, just like crude oil or wheat, according to a document released by the CFTC on Thursday. This means that bitcoin futures and options are subject to CFTC regulations and regulation, and trading behavior needs to comply with all commodity derivatives market rules. If there is any improper behavior such as futures market operation, CFTC will be able to punish such behavior.

6. Of course, he has an identity - "non mainstream" angel investor“ Venture factory solemnly admits that we are "a well-known investor" investing in Huang Taiji. I'm sorry that I haven't announced it in time because I'm always lazy. " This is the statement made by Mai Gang on his microblog a few days ago in response to Hu olfactory network's article questioning Huang Taiji. However, "a well-known" is quoted, because compared with Huang Taiji, who has done a lot of online marketing, the investor Mai Gang is very low-key. At one time, some people even confused the start-up workshop of McGonagall with the Innovation workshop of Li Kaifu, although as an incubator, the former was more than four years earlier than the latter. Mai gang and open the resume of Mai Gang, a word "gorgeous" will surely come to your mind: in 1997, he joined VC; Participate in the preparation of Shenzhen innovation investment company; He participated in the establishment of Shanghai Pudong Science and technology innovation investment company and served as vice president; He is the director of Dfj investment fund; Founded SNS website Yiyou; Set up document sharing website Douding; Founded Tongka and served as the chairman of the company; As the executive director of China Youth Angel Association and President of Tianjin Angel Investment Association... "I was the earliest VC practitioner in China, and then I started my own business, and then I started angel investment, and also contributed to the fund to do LP. These experiences made me see all aspects of the instry, and got through the interests, ideas and entanglements of each role link." In this way, Mai Gang summed up his "GP LP entrepreneur angel investor" track to I dark horse. When dark horse asked McGonagall about his favorite identity tag, his answer was angel investors. At present, he has invested in nearly 60 start-ups. As one of the few angel investors in China who have done GP, LP and business for many times, why did Mai Gang invest in the controversial Huang Taiji? Why did he invest to be an it man in traditional instries? What kind of investment philosophy and principles does he hold? Here's what McGonagall said“ "Cement + mouse" as an investment, I pay more attention to the field of "cement + mouse". This concept was put forward by me in 2009, but it was not really implemented at that time. Since 2011, I have found that most Internet entrepreneurs are unsustainable, while "cement + mouse" is a breakthrough direction. It should be said that my thinking is ahead of time. The actual operation of these cases invested in recent years has also verified my view. Why would I vote for Huang Taiji? Because its founder Hechang uses the Internet idea to enter the direction of the catering instry, I agree with it very much; On the other hand, he is really a talent. He has been in the Internet and Google, and has a deep understanding of Internet marketing and user experience. With both of these, I didn't hesitate to vote. Huang Taiji makes full use of the Internet to improve the marketing and user experience of traditional catering. Later, some people said that they wanted to follow suit and make rougamo, but is it really as simple as microblogging, wechat and topic making? no, it isn't! A company's success, there must be something unknown, such as Huang Taiji's Internet order process, customer experience mechanism and queuing system are all internal operations through the Internet. To be honest, it is impossible for all consumers to like Huang Taiji. It can quickly get users through the Internet at a low cost, which is already very powerful, because as long as the consumer market is big enough, it will make money selling dog shit. The Internet has changed the traditional catering instry in terms of experience and brand connotation. The feeling of eating Huang Taiji is definitely different from that of buying pancakes on the street. The latter will make people feel bad, while the former means petty bourgeoisie to many people. This is the same as Xiaomi's mobile phone, which is labeling itself. In addition, the chaopin store bubble Mart I invested in is also a similar example, from which you can feel the change of the Internet on the supply chain of the traditional retail instry. Wang Ning, the founder of bubble mart, worked in Sina before, and even earlier worked in the retail instry. He is very experienced in combining the Internet with traditional instries. For example, in the past, when businesses purchased procts themselves and then sold them to consumers, consumers accepted them passively. However, bubble mart will introce some Internet factors in the purchasing process. For example, the purchasing data comes from Taobao. Com, and users will participate in the purchasing process. Users will purchase whatever they think is good. Supply chain management is using the Internet mode to enter the consumer led C2B era, which will be the fundamental revolution of retail instry. The Guoku network I invested in also reflects the change of it means and Internet to traditional service instry. Jia ran, the founder of guoku.com, neither used Internet marketing as he Chang did, nor did he do very traditional retailing as Wang Ning did. He chose the better way to start with fruit cutting, and used it technology to develop system, control order process and establish purchasing system. An ordinary fruit vendor may be able to serve more than a dozen enterprises, but in order to serve thousands of enterprises well, we must have a strong management and operation system, which will give full play to the advantages of it people at this time. The above three are typical cases of it transformation in traditional instries. What kind of it man is suitable for traditional instry? First of all, you must especially like doing dirty work. Many it men can't pass this level. Too many people like to pursue hot spots. At the same time, you also need to understand that the Internet is not a panacea, it can not be applied to any instry. You have to find some suitable areas. For example, it's no use to do the same retail business. There is a lot of room for the development of experiential and non-standard retail business. Therefore, entrepreneurs should understand this trend and keep up with it intelligently. Many entrepreneurs follow suit. When others make apps, they make apps, but they don't know that the sky has changed. Many people think that the businesses I invest in are small businesses without threshold. However, in my opinion, there has never been any small business in the consumer instry. Businesses with low threshold often indicate that the greater the market demand. And scale is always a very important thing, as long as you use the Internet, you can continue to expand users, and through it technology for large-scale operation management. Why invest in "cement + mouse"? No matter how you play with the Internet, you can't get out of the traffic circle, because its essence is to pour traffic. If a start-up company relies too much on external traffic, it means that it will always work for others. After purchasing traffic, it has to establish its own business model. Why don't most e-commerce companies make money? Because the essential core of e-commerce is not online, but your brand, category, proct promotion and cumbersome supply chain management. Therefore, the more external traffic you have, the more things you rely on others, and the more vulnerable you are. A person's golden age for starting a business is from 25 to 45 years old, which is only 20 years. Therefore, a person's life is limited. A few years in the traditional consumer service instry can at least earn some money. For example, selling a pancake can sell tens of millions of yuan a year. Even if someone invests in you in the Internet instry, you can burn for five years at most, and in the end, it's just a dream. In the traditional instry, you can get financial freedom after five years. This is my advice to entrepreneurs. There are few "dragon and phoenix" in the world. Many entrepreneurs are doomed to fail. Most businesses are destined to be small businesses. Not everyone can become Microsoft and Google. The biggest innovation must be cyclical. The major innovations in the history of Internet development are nothing more than portals, search and communities. The others are all small waves. What's the use of minimally invasive surgery? It was copied the next day. In the past, there were always entrepreneurs who talked about micro innovation. I think this is at most a knack for starting, not a sufficient condition for success. Most entrepreneurs regard entrepreneurship as an effort to realize themselves, but they overestimate their ability and determination. Before seeing through the essence of the instry, they say that they will persist until they find the direction. It's good to have determination, but success or failure is not measured by determination. In front of the instry trend, people's power is very small. So go back to the old saying "men are afraid of getting into the wrong business". Persistence and maintenance are different. The consequences of maintenance will be very serious. It's a waste of youth, time and money. It's better to die early than to live early. First of all, I am a thinking person. In addition, I have also started a business, and I know very well how an enterprise operates. Entrepreneurship can be successful first because you grasp the strong demand, which is nothing more than using new means to meet the needs of the past, or because of the changes of the times and generate new strong demand, but strong demand does not exist every day. After grasping the strong demand, you need to use good procts to meet this demand. So, I never talk about the concept, just think about what needs have not been met“ A lot of investors are bosha. "How does the venture capital circle play now? First of all, entrepreneurs should have a good relationship with the media and strive for frequent reports. Even if there is speculation out of thin air, it should be done. Then a group of investors will choose to invest when they see which project has high exposure. In fact, many investors are bosha, many entrepreneurs with their money everywhere. Nowadays, investors are very impetuous and lack the will and ability to think independently. They basically follow the trend and go where the hot field is. I think this is a very serious problem. In the past few years, the investment circle has been pursuing hot spots and investing at a high price. Looking back at these crazy cases in three or five years, you will find that most of them will end in failure. If you are right in speculation, if you are not greedy and quit as soon as possible, you will make a lot of money. If you are wrong in speculation, you will lose everything. The success rate of the whole angel investment circle is certainly less than 20%, and my investment success rate is 30%. The investment circle and the entertainment circle are the same. They all show their best side to everyone. They go home to eat white rice and pickles and cry secretly. Angel is OK, loss is also their own money, even if the cry. Institutional managers have to describe their performance in various ways. After all, they have to be responsible to LP. We can't take the success of super angels like Xue Manzi, Lei Jun and Xu Xiaoping as a general probability, because they are successful entrepreneurs and have the qualifications and contacts that most angel investors don't have. So how to define successful angel investors? In mcgang's eyes, he has always been reluctant to use the rate of return to define success. Angel is definitely not a simple investment behavior. It is difficult to obtain long-term happiness only for the purpose of return. Supporting innovation, achieving others, and cultivating new forces in China are all the meanings behind angel investment“ I'm already very lucky. "I've invested in nearly 60 companies, one third of them died, one third of them survived, and one third of them survived better. Looking back on the enterprises I built in those years, it is not a big success in terms of results, but it is very accurate in terms of trends. Of course, the reason why there is no great success is basically only one's own problem. Entrepreneurship is the world of success and defeat. There is also an objective reason that we have not obtained large-scale financing, because Chinese investors are all hot investors, while my projects are all at the forefront of the trend. If you can't get financing, it means that you don't have the money to expand on a large scale, so the momentum will graally weaken. However, continuous entrepreneurs are lucky to be like me. In 2005, I became
