Oceania bitcoin
Let's start with a simple conclusion: a year ago, the data showed that there were about 500000 BTC
two American brothers, Cameron winkleworth and Taylor winkleworth, claiming that they owned 1% of bitcoin [1] 1% of the world's bitcoin? At present, the total amount of bitcoin in the world is about 12 million, that is to say, the two brothers hold about 120000 bitcoins< maybe you don't think it's worth much, but note that the starting price of bitcoin for these two people is less than $10 / bitcoin
Please note that entities are used instead of people. In the analysis method of this paper, bitcoin wallets that may belong to the same owner are divided into the same entity, which may be not only a person, but also a trading organization like Mt. GOx in addition, through the analysis of the most active entity table given in this paper, the income of the people with the most income (excluding expenses) is less than 700000 BTC. In other words, the person with the most bitcoin will hold no more than 700000 bitcoins. How many people in the world own bitcoins? The paper concludes that as of May 13, 2012, 1.85 million entities hold bitcoin. If we assume that bitcoin users have grown linearly since the advent of bitcoin (January 2009), the current number should be 2.5 million. Because the number of entities is counted on paper, the actual number of bitcoin holders should be a little less than this number, but not much smaller, because after all, there are not many large trading platforms
In addition to the above two problems, [3] also gives many interesting conclusions, such as: < UL >about 55% of bitcoin can be saved without money
in places like GOx mountain, almost all deals are small ones
before May 2012, almost all large single transactions (& gt; 50000 BTC) are subsequent transactions of 90000 BTC on November 8, 2011. There are very strange patterns in this long list of transactions. For example, an entity divides 90000 BTCs into different sizes, sends them back to itself three times, and then sells them on Mt. GOx. 90000 BTCs sold are sent back to the entity through 90 different bitcoin addresses, with 1000 bitcoins per address. These operations indicate that the entity appears to be trying to hide the relationship between these transactions
1. It is essentially like an e-commerce platform
2. He said that making money is to earn money, which is worth one yuan of consumption power
3. After asking, can't I cash the money
however, because of its consumption value, if it can circulate, it can still play well

it's OK to have no independent graphics card, but because the CPU speed can be ignored compared with the graphics card, it's very slow (I3 only has about 2.5m speed, helpless), so it's not profitable to use only CPU to mine
-
according to the bitcoin generation algorithm, bitcoin is becoming more and more difficult to dig
-
Mining with NVIDIA graphics card, unless you use gtxtitan, gtx690, gtx680 and other monster graphics cards (thousands of silver), other absolute loss (calculated into electricity, network, equipment)
-
you can use amd graphics card mining, now the most cost-effective mining graphics card should be HD5870 (700 yuan), If you overclock a little, you can get 400m speed, HD5970: 700m. You can also buy a hd7990 (9000d ocean, 1200m speed) regardless of the cost, and earn a few bitcoins a month

The bitcoin white paper was first published at the end of 2008, when the creators sent it to multiple recipients on an encrypted mailing list. Strangely, its creator pretended to be Satoshi Nakamoto, hiding behind the pseudonym
Another reason for Nakamoto's anonymity can be explained as that the creators of alternative currencies easily put themselves at risk In 1998, Hawaiian resident Bernard von nohaus created a private currency called free dollar. It has been popular for some time, but its coinage was suddenly raided by the FBI and secret service in 2007. After a criminal lawsuit in 2009, the money was confiscated and Bernard von norhaus was convicted of "making private coins that compete with the official currency of the United States." In addition, in 2007, a digital currency called e-gold was accused of being illegal because it did not collect enough customer information. Its owner was sentenced to house arrest and the company was shut down. The arrest of entrepreneurs in alternative currencies by government agencies may have been a factor in China's decision to remain anonymouseveryone can use bitcoin. This means it can be used to pay for legal and illegal services, as well as legal bids however, it has always been a popular payment method in the black net market. Ross Ulbricht, the notorious dark Internet market maker and operator, was jailed for facilitating the trading of drugs and other contraband
Ross Ulbricht appealed to the US Supreme Court in December 2017, but is still in prison. If Nakamoto reveals his true identity, it can be inferred that he may face a similar fate
who would he be
in 2016, Craig Wright, an Australian programmer, claimed to be Chinese. He provided some evidence, but later found that it was not conclusive because it could be obtained publicly from books. He was also accused of falsifying announcements and blog posts to show his real Chinese version. For example, vitalik buterin, founder of Ethereum, recently called Craig white a liar
The other is Hal Finney. He is a famous cryptopunk and Cryptologist. He was also the first person to receive bitcoin from Nakamoto in 2009. He was also the first to download a bitcoin client. Before his death in 2014, however, Hal fini refuted the claim that he was Chinese Some people think that Nick Saab, a famous Cryptologist, may be Nakamoto. Before the launch of bitcoin, he designed the architecture of distributed digital currency, which he called bitcoin. Although the architecture has never been moved, it is similar to the design of bitcoin. This led to widespread speculation. But he repeatedly denied italthough the real identity of Nakamoto may never be disclosed, it is important that the operation of the technology will not be affected

many people are wondering what is the difference between IELTS and TOEFL in the English test. The following editor will share the relevant content about the difference between IELTS and TOEFL Reading, hoping to help the students who are preparing for IELTS
the purpose, ration and form of the first test. IELTS test is designed for non English students who apply to study or immigrate in English (U.S., U.K., Australia, Canada, New Zealand, etc.) to assess their ability to use English. TOEFL most American universities and institutes require foreign students to have a certain standard TOEFL score when applying. In terms of test time, IELTS test time is relatively short, with a total length of 2.45 minutes. However, because oral English needs to be tested separately, it takes one or half a year to complete the whole test. The ration of TOEFL is 4 hours. Listening, speaking, reading and writing are completed in succession. So it's a big test for students' physical and mental strength. For students preparing for TOEFL, it is very necessary to prepare psychologically and physically
the length of the content. Although reading is middle school students, contact with English is from reading, since childhood read a lot of things. Reading is one of the four subjects of listening, speaking, reading and writing, but most of the students are surprised by the length of reading
the number of words in the explanation articles given by TOEFL is about 700 words. According to the statistics of articles in TOEFL, online test and og, the average number of words in each article is 700.7 words. Therefore, both the global organization data and the statistical data are very close. In these articles, the number of words more than 750, less than 650 words. It can be seen that TOEFL has made very strict rules on the number of words in order to achieve the purpose of testing students' English ability at the rated time. The average length of IELTS reading articles is more than 900 words, most of which can reach about 1500 words. From this point of view, IELTS word number should be more flexible. I think the number of words does not necessarily determine the difficulty of the article. Because TOEFL and IELTS in one point is very similar, that is to do the right topic, do not have to read or read the full text. But the change in the number of words is also a variable factor for candidates. In my opinion, all the variable factors will have a certain impact on candidates
there are a lot of reading questions in TOEFL and IELTS. Knowing their differences can help us prepare for the test according to different characteristics and get good results. In this paper, from the perspective of reading to answer the heart of many examinees, with the big difference between IELTS and TOEFL. You can choose two or more items to compare
the form and quantity of the questions. There are 8 types of questions in IELTS. Although there are 10 types in TOEFL, the negative fact information question and the fact information question can be classified into one middle school. The icon question is not often tested, so it is also 8 middle school. It is slightly different in the form of examination. TOEFL is all multiple-choice questions (a summary is multiple-choice), IELTS will still have to fill in the blanks. However, all the tests are based on the details of the article, the ability to understand the language of long and difficult sentences, and the skills of locating and agreeing to replace. At the same time, each type of TOEFL and IELTS also has its own problem-solving skills. In this respect, the two are equal
reading vocabulary requirements. In this respect, the vocabulary requirement of TOEFL is 8000, and that of IELTS is 6000. But the comparison of the number of TOEFL is a little difficult. And the selection of TOEFL Reading pays more attention to the consideration of biology, and the difficulty of biology subject vocabulary is also worth mentioning. Therefore, in terms of quantity and quality, the number of words required in TOEFL is relatively large. What's more, the number of 8000 required to master is far more than that. If the ability of guessing words and understanding sentences is not strong, some words that do not need to be memorized will also constitute a reading barrier, so that the performance will have a great impact.
