Is digital currency safe

Publish: 2021-03-22 19:33:34
1. This is an investment,
before the digital currency has no circulation,
it is worthless,
it has no value,
only when it is recognized by everyone,
it can circulate,
it can show its value,
just like bitcoin,
not all digital currencies can be recognized as bitcoin,
it can be recognized by everyone,
there are certain risks.
it is possible to appreciate,
but it is also possible to depreciate,
it is possible even to be worthless
hope to adopt,
thank you!
2. Well, if you don't know whether it's safe or not, it depends on yourself. Otherwise, if you use it, the person who has used it may feel safe, and the person who hasn't used it may still be worried
3. It's not very safe. Digital currency is different from other real currencies. It's virtual and easy to have problems in the network. My suggestion is not to invest in digital currency.
4. Toobi, there is no problem at present. The payment is fast,
5. As long as it is a digital currency, it is impossible to be safe, because there is no perfect thing in the world; Digital currencies are sometimes more insecure.
6. 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;
7. Digital currency transaction is not safe, investment should be cautious.
