2. It is definitely recommended that you register with easybtc. Relatively speaking, the safety factor of this platform is among the top.
3. The following is for reference only:
very large
in the field of blockchain and virtual currency, such cases of losses caused by the security of exchanges occur frequently, causing great economic losses to users. The security experts of Juhui ggfx also gave a hint: there are still many loopholes in the current digital currency trading platform, for example, the most common are the following six kinds:
the first kind: denial of service attack
denial of service attack is the most important attack against the digital currency trading platform at present. Through denial of service attack, the attacker makes the trading platform unable to access normally, Because users can not accurately distinguish the degree of attack, it often causes panic asset transfer, which brings some loss
the second kind: phishing
even the best technical measures at present can not make the digital currency trading platform avoid phishing attacks. Some hackers and outlaws can confuse digital currency investors by means of fake domain names or fake pages, while ordinary investors can't identify the authenticity, so it's easy to cause asset losses
the third: Hot wallet protection
many digital currency trading platforms use a single private key to protect the hot wallet. If hackers can access a single private key, they can crack the hot wallet related to the private key. For example, in the attack on yapizon of Seoul stock exchange in 2017, the attackers stole hot wallets from the trading platform twice in a year, resulting in a total loss of nearly 50% of the assets of the trading platform and eventually leading to the bankruptcy of the trading platform
Fourth: internal attack
e to the lack of perfect risk isolation measures or ineffective supervision on the authority of employees, the digital currency trading platform also has employees' self-monitoring and stealing, and some employees with operating authority of the platform use internal trust to seek ill gotten gains for themselves. For example, in 2016, the event of employees stealing bitcoin on shapeshift caused a total loss of US $230000 to the trading platform by stealing and reselling sensitive information to others
the fifth: software vulnerability
the software vulnerability of digital currency trading platform includes single sign on vulnerability, OAuth protocol vulnerability, etc. At present, all countries have laws requiring banks or other financial institutions to implement information security measures to protect customers' deposits. However, e to the fact that the blockchain field is still in its infancy, there is a lack of such specifications for encrypting digital assets. Therefore, it is not accidental that many trading platforms have a large number of loopholes in the absence of security constraints
sixth: transaction malleability
Technical supporters of blockchain often think that blockchain transactions are highly secure because they are recorded on records that are said to be unchangeable, but each transaction needs to have a corresponding signature, and the records can be temporarily forged before the final confirmation of the transaction. Mt. GOx, which once accounted for 80% of the world's total transactions, was hacked to submit code changes to the public ledger before the initial transaction was released, resulting in a loss of 473 million US dollars< br /> &# 160;

4. A few years ago, digital currency could only be said to belong to a niche market, and there were very few currencies that could be used as investment currencies in the market. Until 2017, a fierce fire burned the passion of the currency circle. Large currencies were called mainstream currencies, while dense currencies also came. These small currencies can also be called Shanzhai currencies. The effect of creating wealth has created a lot of rich people, and it has also led to a long road of speculation. The good times are not long. The top 50 currencies in the global circulation market value have suffered a terrible decline after 2018. They are all rushing to the rhythm of returning to zero, and even investors' leeks are harvested all over the land, with a decline of more than 95%. Bankruptcy has long been common. The bear market has also squeezed into the previous bubble, leaving 0 of the junk money and fraulent items closed or closed down, which is a spring for the real block chain instry, and has entered a virtuous cycle and guiding role.
the reliability of digital currency is always landing. The key long-term point of an instry is whether it can be landing. Let's not talk about the key figures of this project, but about the feasibility of this project. There is no project that can be implemented, how high the project party praises, star stations and so on. To return to the original place, the truth is a pit
for example, HNB, the next generation of decentralized blockchain economy, is a reliable project. It relies on the real economy and uses value exchange to continuously create endogenous value. It uses blockchain to build an economy in which everyone can participate and get returns through labor. It no longer relies on currency speculation for income, At the same time, it can help the real economy create new vitality.

5. Another risk of digital currency is credit risk. Because there are middlemen in digital currency transactions. Therefore, many criminals use digital currency as a new money laundering channel
6. It is wrong to say that China's digital currency comes from the people, because it comes from the present. Science.
7. Go language has not shown a clear direction since its appearance. Google employees call it an "experimental language", saying that it tries to integrate the development speed of dynamic languages such as python with the performance and security of compiled languages such as C or C + +. A supporter of go language summarizes that go language is as follows: simple, fast, safe, concurrent, happy programming, open source; But go language lacks direction and the attempt of its "synthesizer" will easily lead to its failure to learn from cats and dogs, and become a four unlike. Nevertheless, the editors still think that go language has great potential: many developers are interested in it - not only its original designers have a strong lineup, but also the people involved in modifying the source code. This is likely to help go language find its own direction and open up a new direction of system programming.
8. Crash is inevitable, it is not any securities, no one does it endorsement credit certificate, nothing, if it is really so valuable, it will not fall around to cheat.
