I have always trusted btc123. In 2013, I first found the fxbtc mainland platform on btc123 to buy bitcoin, and fxbtc collapsed and lost a lot of bitcoin. At that time, I thought that the mainland platform was not very reliable. Then I found mycoin on btc123, the Hong Kong platform. Considering that the legal system in Hong Kong is more perfect and btc123 is an endorsement, it should be safer. So I bought 2 million bitcoin from huocoin.com and transferred it to the multi currency treasure in mycoin platform for storage!!! Often login multi currency account, has been able to log in, and every day there is interest payment. In February of 2015, I happened to see the news that the boss of the platform ran the road and Hong Kong's capital took 3 billion yuan away!!! Then the mainland economic investigation called the police and refused to accept it. It said that the office address was in Hong Kong and asked me to call Hong Kong to report to the police. The Hong Kong police station received a call saying that I should report to the police in the mainland, and bitcoin did not accept the call to report to the police. Finally, it said that I could report to the police online first. I called the police on the Internet, no news!!! Now call the day should not, call the ground not work!!!! I hope the media, the government or the police can help me. I can't say that I have no hard-earned money for 15 years! I wonder if we can sue btc123 together? What else can we do to rece the loss? Thank you

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.

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.
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.
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.
