stolen
mark kalpler, chief executive of mt.gox, bowed his apology at a news conference held in Tokyo yesterday, saying that "the loss of bitcoin is e to a loophole in the company's system"
a lawyer for Mt. GOx said that almost all the bitcoins traded on the platform were stolen, including about 750000 bitcoins in the user's trading account and about 100000 bitcoins in Mt. GOx's own account. According to the trading on February 28, the loss is estimated to be about $467 million
according to media reports, mt.gox trading platform had more than 1 million accounts at its peak, mainly from customers outside Japan, including many users trading more than US $10000. Some bitcoin investors have rushed to Tokyo from overseas in an attempt to recover trading funds from Mt. GOx
on February 7, e to hacker attacks, mt.gox temporarily stopped the bitcoin extraction business, causing transaction confusion and user dissatisfaction. From the noon of February 25, users cannot log in to mt.gox trading platform. The home page of the website then pasted a "notice to customers" to suspend all transactions
Li, a native of Hefei, spent 140000 yuan to buy 124 bitcoins in October this year. Afterwards, Li joined some chat groups of bitcoin players to pay close attention to the bitcoin market. On October 22, a person named Michael in the group took the initiative to chat with Li and asked him if he was mining“ I won't, and I won't get any money. " Mr. Li replied. Michael repeatedly urged Li to have a try and sent him a "mining tool", claiming that he could use the tool to dig more bitcoin. In the subsequent chat, Michael constantly reminds Li to put bitcoin in his wallet, saying that the trading website is not safe“ From time to time, there are news that trading websites are closing down and running away. What he said is quite reasonable, so I believe him. " Li told Anhui Business Daily
100 bitcoins disappeared
Li received and installed mining tools. On the evening of October 26, he was inced by Michael to put 100 bitcoins in his wallet. However, when the bitcoin in the E-wallet just reached 100, it suddenly disappeared. Li suddenly panic God, and then contact Michael, the convenience of invisible disappeared
Li told reporters that at present, a bitcoin costs about 5000 or 6000 yuan, and 100 bitcoins are worth 500000 or 600000 yuan. Afterwards, Li reported the case to the police. However, to Li's disappointment, because bitcoin is a virtual currency, there is no relevant domestic law to regulate and protect its transactions. The police did not file a case“ Now, this man named Michael is still active on the Internet. He's just taking advantage of the law. " Li told Anhui Business Daily
there is a Trojan horse in "mining tools"
How could Li's bitcoin disappear? 360 security engineer contacted him and tested Michael's "mining tool", and found that this tool is a very popular "bitcoin robber" Trojan horse this year. According to the analysis of 360 security center, most of the "bitcoin thieves" Trojans are disguised as mining tools, simplified wallets and other compressed files. Once a player is recruited, the Trojan will automatically search for bitcoin wallets and steal them through e-mail, hacker remote control and other means.
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
in a recent article in the New York Times, a Venezuelan economist described how bitcoin became a part of Venezuela's daily life, so that on a mainstream bitcoin trading platform, Venezuela's trading volume ranked second only to Russia in the world. But bitcoin is not just used to protect wealth in extreme conditions. In general, bitcoin is also an excellent choice for portfolio diversification, and it should be seen as part of a comprehensive wealth preservation strategy.
According to foreign media reports, although the price of bitcoin has dropped sharply this year, the cryptocurrency conference is still a major event
This week, coindesk, a well-known bitcoin news website, will hold a three-day bitcoin conference in New York City with a ticket price of about $2000. It is expected that 4000 people will attend the meeting, which is a lot more than last year's 2700 people. As a result, ticket revenue for the conference will be at least $8 millionwithin a few days of the bitcoin conference in New York, there are 20 other conferences held at the same time, and the ticket price of these conferences is also very high. Three years ago, the consensus conference was first held, and only 400 people attended. Now, the conference has become the main feature of blockchain week NYC
before and after the consensus meeting held in May last year, the price of bitcoin soared to about $2000. Of course, this is also the result of the first tokensummit summit and ethereal summit
since then, the price of bitcoin has skyrocketed, successfully attracted the interest of Wall Street, and exceeded $10000 for the first time after the consensis invest meeting held in November. In December, the price of bitcoin peaked at more than $19000. But since then, its price has fallen by more than half
strong speaker lineup
this year's speaker lineup shows that the cryptocurrency instry has taken an important step towards the mainstream direction. Jack Dorsey, co-founder of microblogging site twitter, is e to speak at the consensus conference on Wednesday. Square, his mobile payment company, also launched bitcoin trading this year. Other members of the meeting's expert group include government officials and heads of start-ups
"the consensus conference is very famous. If you give a speech at the conference, it means that you are also very famous." Said Michael oved, co-founder of airswap, the cryptocurrency exchange. He is also the organizer of the fluidity blockchain conference held last Thursday
he said that he deliberately lowered the ticket price of his fluidity conference to $150-250. Because he thinks it's a "good opportunity for us to share what we're studying.". About 700 people attended the fluidity conference, and ticket sales reached about $140000, oweed said
"ironically, the organizers charge a lot, but they never pay the speakers. These speakers are the people who are most concerned about the development of the blockchain community and are most eager to share new developments. " She tweeted on April 28
she will give speeches at ethereal summit and consensus meeting this week“ Neither of these meetings paid me for my speech. " She said. She added, "live online is a great way for the public to watch the content of the conference."
"too many meetings, it's crazy"
all kinds of meetings are very powerful and lively, but we don't know whether they finally help start-ups, especially those with imperfect management
"there are too many meetings now. It's crazy." "In the San Francisco Bay area alone, there's a weekly meeting on blockchain," oweed said. It's easy for us to be distracted by these meetings. "
however, some people are convinced that these meetings will eventually be the catalyst for the recovery of bitcoin prices
"after the previous consensus meetings, the price of bitcoin will rise. This fact strongly supports our view that the price of bitcoin has hit the bottom this year. " "During every meeting, the price of bitcoin goes up 10-70%," Tom Lee, co-founder of fundstrat global research, a market research firm, said in a research briefing on May 7
he added, "considering the significant increase in the number of participants, we believe that the price of all cryptocurrencies will increase similarly."
a block is a collection of many transaction data, which is marked with time stamp and the unique mark of the previous block. Effective blocks will be added to the main blockchain after being recognized by the whole network. Blockchain is a data structure in which blocks containing transaction information are orderly linked from back to front. In the virtual money market, the most well-known application of block chain technology is bitcoin< At 3:00 p.m. on September 4, 2017, the people's Bank of China and other seven departments jointly issued the notice on preventing the financing risk of token issuance, which defined ICO as "an unauthorized illegal public financing behavior". At the same time, the regulatory authorities said that all kinds of token issuance financing activities should be stopped immediately, Organizations and indivials that have completed the financing of token issuance shall make arrangements such as refund. A vice president said, "it is normal that the rapid development of ICO has attracted the attention of regulators. According to the traditional law, ICO has the suspicion of crowdfunding and capital raising, and there is a great risk of laissez faire development without supervision. A large number of projects with no future even cheat themselves, which not only makes investors bear huge risks, but also makes the real blockchain entrepreneurial team complain a lot, which actually leads to the bad consequences of bad money driving out good money. The admission of a large number of retail investors and even "aunts" is just a weather vane - it's time for the regulatory intervention of ICO. This rectification is mainly to warn of risks and protect the interests of investors. "
ICO does not issue stocks, but digital currency, which is commonly known as token. Blockchain start-ups exchange bitcoin, Ethernet and other digital currencies in the form of crowdfunding to achieve the purpose of financing and entrepreneurship. Blockchain investors and entrepreneurs are very optimistic about blockchain technology, and think that the vigorous supervision of the government departments is good for the blockchain instry. Through the governance of ICO and the expulsion of digital coins, the blockchain can develop more steadily. It is hoped that this regulation can really crack down on pyramid selling currency and air currency, screen and treat seriously entrepreneurial blockchain innovation projects differently, and protect the interests of serious investors and entrepreneurs
blockchain technology can play its role in banking, mobile payment and other fields.
