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.

According to Chaina alysis, a research firm, up to 20% of the existing bitcoin has disappeared forever. At the time of the study, about 3.8 million bitcoins could never be retrieved. In this article, we will explore all possible ways to lose bitcoin

1. Cryptocurrency hackers

the hacker behavior of cryptocurrency exchange is the main reason for the loss of bitcoin. Exchanges are a hot target for cyber criminals, accounting for 27% of cyber attacks in 2018. Mt. GOx was the first high-profile cryptocurrency hacker, but since then, many major exchanges have been hacked, including bitfinex, bitstamp and, more recently, cryptopia, the cryptocurrency exchange in New Zealand, which lost 9.4% of its total positions

Malware

the malware on torrent website and Google play store are used to steal passwords from vulnerable categories. For example, there is a malware clipper that uses users' behavior of ing and pasting wallet addresses to steal passwords. For example, if you send BTC to an address, you usually and paste the address, because it is a long string of random characters, clipper malware will exchange wallet addresses, which means that when you paste, you will send encryption to the wrong address

1、 Open pit mining: in general, diamond mines are mined around kimberlite pipes. The middle of the pipes is the place where high-quality diamonds are most concentrated, which is usually characterized by huge holes. When the Kimberley rock pipeline was found, miners g out vertically from the ground surface

Second, underground mining: this mining method is safer and more efficient, especially with the deepening of the mining process, it is difficult to judge whether to continue mining to expand the mine. Underground mining only needs to open a tunnel to extract diamonds under the surface, which is more reasonable and less dangerous. Sometimes a combination of underground and open-pit mining is used to make a tunnel from the pit into the surrounding rock

Extraction of kimberlite from the mine: kimberlite can be released from the earth's crust by artificial explosion, and a large number of rocks can be destroyed by explosion, but it can not be detected on site. It is wrapped with diamonds and must be transferred to another place for processing and diamond extraction by large trucks and steam shovels, Generally speaking, there are 0.5 carats of diamonds in one ton of mud

(4) percussive Mining: rivers and streams will bring kimberlite to the river bed, shore, or even coastal zone to form percussive sand deposits. Percussive mining is also known as artificial mining, because the miner has to go to the percussive sand deposit to search for diamonds artificially. The farther away from the kimberlite pipeline, the lower the output of diamonds and the more sparse the distribution density of diamonds. Therefore, percussive mining is not suitable for instrial diamond mining

extended data

1. The Kimberley diamond deposit was discovered by the Burnett brothers in 1870. It is this discovery that makes people know which kind of rock may contain diamond. It's a volcanic rock formed after the magma of ancient times cooled. In places where garnet and olivine are proced, the possibility of finding diamond is relatively high. Therefore, garnet and olivine become the "indicator minerals" for diamond

From 1866 to 1914, 50000 miners used shovels and other tools to excavate, and a total of 2722 kg of diamonds were excavated. The South African government is trying to apply for the Kimberley pit as a world heritage site

Third, open-pit mining is a process of removing the covering from the ore body to obtain the required minerals and extracting useful minerals from the open surface stope. Open pit mining operation mainly includes perforation, blasting, mining and loading, transportation and mping. Compared with underground mining, open pit mining has the advantages of full utilization of resources, low dilution rate, suitable for large-scale mechanical construction, fast mine construction, large output, high labor proctivity, low cost, good working conditions and safe proction

4. The bank can come to understand

5. It can be split, and one becomes 1000W

6. Bitcoin is certainly difficult to track back in the future, because this is the asset money lost, it is impossible to recover

7. All the other answers are rubbish.. The missing part still exists in the total amount.. The future total is dead. Missing items are also included and will not be cleared out of the total amount.

8. This is very difficult to find. Failure to confirm is proof of the failure of this transaction and failure to obtain confirmation from the network. Bitcoin receives payments almost instantaneously. However, there is an average delay of 10 minutes before the network starts adding your transaction to a block to confirm the transaction and that you can use the received bitcoin. Confirmation means that there is a consensus on the Internet that the bitcoin you receive is not used to pay others, so it is recognized as your property. Once your transaction is included in one block, all subsequent blocks will include it, which will greatly consolidate this consensus and rece the risk of transaction cancellation. Each user can determine the time when the transaction is confirmed, but generally speaking, receiving six confirmations is as safe as waiting six months after a credit card transaction

however, foreign studies have also shown that these bitcoins can be tracked and retrieved, but they are troublesome. At present, they are still in theory, and no company provides such services. Bitcoin house has this convenient report. You can check it on it.

With more and more cases of bitcoin becoming rich, many people realize that the appreciation space behind bitcoin is very huge. Many people are annoyed that they didn't catch the train of becoming rich. Compared with the common legal currency in life, bitcoin is a virtual digital currency. Since its birth in January 2019, the price of bitcoin has increased from US $0.0025 to US $0.0025, After ten years of development, it has successfully broken through to US $31000, and the soaring momentum has not stopped{ RRRRR}

most of them come from bitcoin mined in the early stage of technology. Many people think that these bitcoins are worthless, and they are unwilling to spend time to save them, so they are graally forgotten by themselves, and even many people have long forgotten that they own bitcoin. It must be that those who lost them because they had no hope for bitcoin should regret it now, I can only comfort myself that I have no predestined relationship with sudden wealth

10. No, it has nothing to do with computers
