According to the currency security, the hacking incident only involved the stolen transaction, and only affected the BTC in the coin security wallet (announced that this part of the BTC accounts for about 2% of the total amount of BTC held by the currency security).
For the stolen BTC, Coin said it would use the SAFU Fund (full name "User Security Asset Fund", which was established in July 2018 and invested 10% of all transaction fee income to provide insurance for potential security breaches) Full payment to protect user assets from loss.
At the same time, in order to prevent such incidents from happening again, the currency has suspended all the bitcoin withdrawals and recharges, and will conduct a security review for about a week.

Where is the most secure encryption asset?
According to a report released by the US digital currency security company CipherTrace, in the first half of 2018, the global cryptocurrency exchange had $731 million worth of crypto assets stolen by hackers.
Why do hackers have a soft spot for cryptocurrency exchanges?
The most direct reason is because it is profitable. As an upstream of the cryptocurrency market food chain, cryptocurrency exchanges aggregate the assets of a large number of institutions and retail investors. Compared to attacking individuals, the benefits that an attack exchange can take are even more impressive. Of course, as a head exchange, the currency security is more favored by hackers.
In addition, the reason why hackers dare to do whatever they want is because the cryptocurrency industry, including cryptocurrency transactions, is still largely outside legal supervision. For hackers, the risk of attacking an exchange is much less than attacking other economic entities of equal value, and the cryptocurrency is also uniquely convenient and secure in terms of cash and cash transfer.
More importantly, cryptocurrency exchanges have a relatively low level of security. This aspect is due to the fact that cryptocurrency is different from other assets and cannot exist without the network. As long as it exists on the network, there is always a way to invade. The difference is only the cost. On the other hand, the level of security protection between different exchanges is very different, and the lack of attention to security maintenance is the root cause. The current exchange is more about doing post-processing, not pre-emptive prevention.
In this way, the theft of encrypted assets is almost impossible to prevent. Where is the safest?
First of all, it must be a cold wallet. A hot wallet is an online wallet, and a cold wallet is an offline wallet. In theory, the cold wallet can make the private key never touch the net, which can effectively prevent hackers from stealing.
However, if you want to invest in long-term encrypted assets on the trading platform, it is recommended to choose a head exchange such as currency security and fire currency. Although they are often attacked, the user's assets can still be protected. Even if it is stolen, there are exchanges, just like the 7000BTC was stolen, and the company announced that it will use the SAFU fund to pay the user's damaged assets in full.
The currency is "black" history
In the middle of the night of March 7 this year, the currency security was attacked by hackers. But what's interesting is that during this attack, a large number of users found that their account was stolen, but the hacker did not directly steal the user's cryptocurrency, but sold the cryptocurrency in the account at the market price without the user's knowledge. After buying Bitcoin, the BTC in the stealing account was manipulated to purchase a digital currency called VIA, which drastically increased its price.
This "singular" hacking attack has led to a general plunging of the cryptocurrency market, including Bitcoin, while VIA has achieved a hundredfold increase.
In July last year, the currency security was also suspected of being stolen 7,000 BTCs. Although the currency security did not confirm the matter, at that time, the "About SYS Abnormal Transaction Processing Plan" was issued in time, and the SAFU fund was established in the same month.
For the BTC theft incident on May 8, most of the industry insiders also expressed their views afterwards:
Zhao Dong, founder of Dfund, said, "In the eyes of professional hackers, there is only a time problem, there is no unbreakable exchange. Zhao Changpeng is straightforward and transparent, and I still believe and support the currency security as always."
1. Surveillance and self-stealing. This is not the first time that the currency has been stolen, but it is 7000BTC every time, which is too coincidental;
2. In order to create momentum for the decentralized exchange of the currency;
3. In order to combat the upcoming Bitfinex;
4, hacking is not for 7000BTC, but to create panic, short market;
Those stolen exchanges
According to the data of PeckShield digital asset escort system, as of now, the 7074 BTCs that were stolen by the money security wallet were temporarily stored by hackers in 20 main addresses and have not been further spread.
According to the current BTC price, the total loss of the currency is more than 41 million US dollars, and all user losses will be fully borne by the Kanan SAFU Fund.
This kind of treatment is the most direct. Why are other stolen exchanges in history historically stolen? How is it handled?
