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

2. I met a hacker
there is no way to find out the theft, just like where the blackmail virus is and who blackmailed it is still a mystery
the nature of bitcoin is that it cannot solve cases
bitcoin (bitcoin: bitcoin) was originally a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals.

3. No, there are several reasons why bitcoin was stolen
1. A stolen bitcoin can't be retrieved, and if it's lost, it's lost.
2. Bitcoin has transaction records, but the address is hidden, and you can't find an indivial.
3. Every bitcoin has a key, and only if you have this key can you be admitted to own bitcoin. However, if bitcoin is stolen or lost, your bitcoin will disappear completely
therefore, the theft of bitcoin does not belong to cracking, it may be e to internal personnel.

Bitcoin is a kind of virtual commodity. In recent years, the price of bitcoin has been soaring. Recently, after more than three months of investigation, the Public Security Bureau of Zhongyuan Oilfield in Henan Province successfully cracked the first case of bitcoin theft in China

on July 27 this year, the Public Security Bureau of Zhongyuan Oilfield in Henan Province received an alarm from Wu, a resident under his jurisdiction, saying that he had lost more than 3.4 million yuan worth of bitcoin in his Internet wallet. Wu is a professional investor and has been investing in bitcoin since 2016. In early 2017, he was drawn into a wechat group of bitcoin investors

the victim Wu: at the end of the day, he said he was also responsible. Although he said that he taught me to lose my coin, he was also kind-hearted. He said that he would compensate me for 10 (bitcoin), saying that he could only bear his part of the responsibility. Later, he used Alipay to transfer money to me. If it had nothing to do with him, how could he casually accompany others for more than 100000, not a small number

after cracking the password stealing software, the police arrested the suspect

after preliminary investigation, the police determined that Dai, the leader of wechat group, was suspected of committing a major crime. On August 9 this year, the police controlled Dai in Shanghai. In Dai's home, the police found 27 bank cards and multiple computers. In one computer, as like as two peas, the police found a net wallet software that was exactly the same as the victim's use. p>

it turns out that Dai is proficient in software programming. After cracking the downloaded genuine wallet software, he adds a program to transmit user name and password to steal bitcoin. Once someone deposits bitcoin in the E-wallet, he will know the other party's account name and password, and transfer bitcoin in the E-wallet. He distributed the stolen bitcoin in hundreds of network wallets, transferred it back and forth, and sold it at a low price on the trading platform after confirming its security. In this way, Dai has committed three crimes involving more than 20 million yuan. At present, the police have found out Dai's account and frozen it, recovering more than 2 million yuan of stolen money

according to the police, bitcoin is a virtual commodity, which is difficult to be recovered once there is a problem in the transaction

Su Haizhou, leader of Criminal Investigation Detachment of Henan Zhongyuan Oilfield Public Security Bureau: bitcoin trading platform our country has closed all three platforms before the end of October 2017. At present, the country only recognizes bitcoin as a virtual commodity, not as a virtual currency. So you need to be careful if you want to invest in bitcoin

5. Bitcoin, Ruitai coin, Laite coin and doggy coin are real digital cryptocurrencies with irreversibility. They are a decentralized distributed network, and it is difficult to trace stolen ones.

As far as I know, there are probably two ways to obtain bitcoin. One is to use assets such as cash to trade with other bitcoin users. Generally speaking, the value of assets is determined according to the market value of bitcoin. However, the market value of bitcoin fluctuates a lot, and there may be hackers on the trading platform, so there may be some risks in this way

So if you want to get bitcoin by mining, you need a computer with high performance and a lot of manpower to maintain it. All in all, acquiring bitcoin is an investment and needs to be managed reasonably< br />
