Virtual currency will not be stolen

1.

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

2. Stolen currency and being attacked should be a headache for the exchange and it is difficult to avoid. Large exchanges usually set up their own technical team to develop the transaction payment system. Small and medium-sized exchanges can dock with third-party technical service providers, so the cost of R & D and operation and maintenance is relatively low
the exchange I am familiar with uses the currency payment enterprise version, which is a digital asset security payment system. The general principle is to store the private key locally, bind the exchange's unique client with multiple encryptions, and the system itself does not save the private key, so as to prevent the possibility of digital currency theft from the source. It is also convenient to operate, with unified management of Multi Chain and multi currency and convenient reconciliation
hope to adopt.

3. Digital cryptocurrency is not issued by legal tender institutions and is not controlled by the central bank. It is based on the open source code of a group of equations calculated by computers all over the world. It is generated by a large number of operations of computer graphics card and CPU, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The design based on cryptography can make the cryptocurrency only be owned by real people. As we all know, virtual currency can be divided into two categories: non cryptocurrency (enterprise currency) and digital cryptocurrency
1. Non cryptocurrency (enterprise currency):
it is issued by companies or private indivials, and can be issued indefinitely. It does not need to solve the equation through the CPU program of computer graphics card. Because it can be issued unlimited according to the market demand, it does not have the value of collection and appreciation< Second, digital cryptocurrency:
it is not issued by legal tender institutions and is not controlled by the central bank. It is based on the open source code of a group of equations calculated by computers all over the world. It is generated by a large number of operations of computer graphics card and CPU, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The design based on cryptography can make the cryptocurrency only be transferred or paid by the real owner< What does digital cryptocurrency look like
real open source code is a series of special solutions generated by a series of complex algorithms. After mining, cryptocurrency is a string of codes, just like the serial number in the lower left corner of RMB. As long as you master the open source code, whoever owns the serial number will have the right to use the cryptocurrency. You can really own this financial digital asset
bitcoin, Ethereum, Leyte, doggy, Ruitai, Ruibo, Dasch and so on are the most well-known coins in the ranking.

4. 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. However, foreign scholars have shown that they can be traced, but they are still in the theoretical stage at present. The last time Ethernet coin was stolen, it was a hard fork solution.

5. At present, hackers are focusing on the digital currency exchange. In their eyes, it's all fat and the asset security of stealing customers' information. Many exchanges have more or less security risks. It's recommended to go to the coin exchange to transfer the property safely. The coin exchange has achieved a balance between the security system and the system efficiency. So far, there has been no major security risks

6. Bitcoin cold wallet is a kind of bitcoin storage method that user account and personal key are stored separately
Hot wallets usually refer to bitcoin online wallets, where the user's personal account and password information are all stored on a network platform; Website platform provides security for users
coin pack is a professional website platform providing bitcoin wallet service, which has two storage modes: cold wallet and hot wallet; Overall, the user evaluation is good.

7. Virtual currency is also called digital currency. The underlying technology is blockchain. It depends on the network and ensures its existence and security through mathematics, cryptography and other means.
