Is digital currency a 24-hour transaction

1.

The contract transaction of digital currency is not safe. There are still many loopholes in the digital currency trading platform, for example, the most common are the following six kinds:

1. 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

2. Phishing incident

even the best technical measures at present can not make the digital currency trading platform avoid phishing attacks. Some hackers and criminals 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

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, e to the lack of perfect risk isolation measures, or ineffective supervision on the rights of employees, some employees who have the operation rights of the platform use internal trust to seek unjust wealth 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

Fifth, the software vulnerability of digital currency trading platform includes single sign on vulnerability, OAuth protocol vulnerability and so on. 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

6. Transaction malleability the 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 forged temporarily before the final confirmation of the transaction

rules of contract transaction

1. Transaction time

contract transaction is 7 * 24 hours transaction, which will be interrupted only ring the settlement or delivery period of 16:00 (UTC + 8) every Friday. In the last 10 minutes before delivery, the contract can only be closed, not opened

Transaction types are divided into two types, opening and closing. Opening and closing positions are divided into two directions: buying and selling:

buying open long (bullish) refers to buying a certain number of contracts when users are bullish and bullish on the index. Carry out "buy open more" operation, match success will increase long position

selling pingo (multi order closing) refers to the selling contract that the user makes up for when he is no longer bullish on the future index, offsets with the current buying contract and exits the market. Carry on "sell flat much" operation, match after success, will rece long position

short selling (bearish) refers to the new sale of a certain number of certain contracts when the user is short or bearish on the index. Carry out the operation of "sell short" and increase the short position after successful matching

buy close (short single close) refers to the buy contract that the user will not be bearish on the future index market and make up for, offset with the current sell contract and exit the market. Carry out "buy short" operation, after matching successfully, short position will be reced

3. Order method

limit order: the user needs to specify the price and quantity of the order. Limit order can be used for opening and closing positions

order at opposite price: if you choose to order at opposite price, you can only enter the order quantity, not the order price. The system will read the latest competitor price at the moment of receiving the entrustment (if the user buys, the competitor price is the selling price of 1); If it is a sell, then the counter price is buy 1 price). Issue a price limit order for this counter price

4. Position

the user owns the position after opening and trading, and the positions in the same direction of the same contract will be merged. In a contract account, there can only be 6 positions at most, that is, multiple positions of current week contract, short positions of current week contract, multiple positions of next week contract, short positions of next week contract, multiple positions of quarterly contract and short positions of quarterly contract

5. Order restriction

the platform will restrict the number of single user's positions in a certain period of contract and the number of single open / close positions, so as to prevent users from manipulating the market

when the number of positions or entrustments of users is too large, the platform has the right to require users to take risk control measures, including but not limited to cancellation of orders, closing positions, etc. The platform has the right to adopt measures including but not limited to limiting the total number of positions, limiting the total number of consignments, limiting the opening of positions, withdrawing orders, forcibly closing positions, etc. for risk control

About your question, my first feeling is:

1. personally, I don't think you have a good understanding of the concept of digital currency (of course, it is very likely that I don't understand your Zheng Sisi very well, sorry). I suggest you go to the Internet search to find out the explanation of digital currency, bitcoin and other networks

2. digital currency mainly represents or narrowly refers to bitcoin, which is the world's first kind of money or wealth truly owned by a private person. This can be explained by referring to the Internet. Since it is a wealth or currency completely owned by a private person, it means that no one can freeze it or confiscate it, So there is no charge at all

3. as long as bitcoin is stored in a wallet that completely controls its private key, such as the offline paper wallet created by bitcoin offline (specific web search: Secure offline paper wallet of bitcoin), such as the paper wallet, which has never been in touch with the Internet, as long as you don't say it yourself, you will never know it again, This is the best explanation for full ownership. In that case, who will charge

4. in conclusion, if I understand your question, holding a completely private digital currency will not generate charges< br />

3. Certainly, but there will be some price difference between each platform, because there are some differences in the market

4. The algorithm of each trading platform is different, which should be calculated according to the platform
some platforms are calculated by 24 hours, some by day, and some by average price. Specific algorithm or to ask the relevant trading platform, this is no standard answer
there are risks in digital currency investment, especially since digital currency has recently entered a bear market, investment should be more cautious. It is better to invest in mainstream digital currencies such as bitcoin, bitcoin cash and wikilink, which have passed the test of the market.

5. You asked this question. If you lose money in buying stocks, can you still get it back? Bitcoin investment is ups and downs, I advise you to be cautious!

6. QQ is very familiar to many netizens. From the initial online chat tool to the later game center, QQ can occupy a large position in the online world. Now its QQ coin has caused controversy. Some people say it will impact the financial order, while others say it is just like a meal ticket in a canteen. For tens of millions of young netizens, "QQ coin" is a word that can make them "shine in front of their eyes": turn on the computer, log in to QQ, go to the mall to buy beautiful clothes for their QQ portraits Go to the game center to play Gobang with people and "fight" several games of Tetris... For many netizens, these daily required courses are simply impossible without Q coin

in November, a scholar named Yang Tao published an article questioning q-coin. According to the article, virtual currency merchants such as q-coin can issue unlimited, and virtual currency becomes the general equivalent of online transactions instead of RMB, which may impact China's financial order, "and the consequences of flooding are unimaginable."

after the publication of Yang Tao's article, it caused an uproar of "torture" Q coin

is Q currency a commodity or a currency

in this debate, what attracts people's attention most is: how to define the identity of Q coin? Is it a commodity or a currency? The "ambiguity" of q-coin lies in that, to a certain extent, it seems to have some "payment" function

"Q currency shows the attribute of commodity rather than information currency," said Alamus, deputy director of the policy and regulation committee of China E-Commerce Association. Shells, precious metals and other commodities with certain use value have been used as equivalents for commodity exchange. This special equivalent is different from the general equivalent in that it is also a commodity and has certain practical functions. "

according to Alamus, q-coin itself is a kind of commodity, just a special commodity with exchange function in a certain range

Lu suiqi, deputy director of China Financial Research Center at Peking University, believes that q-coin does not have the typical characteristics of currency

"whether a commodity can become a currency depends on whether it can act as a general equivalent, whether it can act as a substitute for real currency, whether the issuer has a credit background, and q-coin almost does not have these characteristics. Q-coin is a kind of commodity and a means of promotion for companies. Transactions with q-coin as the medium of exchange tend to be barter or semi barter. " Lu suiqi said

LV suiqi believes that q-coin should not impact the RMB market or affect China's financial order. Because Q currency "is very difficult to perform the function of currency"

q-coin is not "virtual currency"

whether q-coin can be regarded as "virtual currency", Alamus cited the example of online banking

"when we use the online banking procts or services of ICBC or CMB, we can't see cash, but there is a real transfer of funds. Our funds in online banking belong to virtual currency. " Said Alamus

7. Eulo modifies the underlying network transmission protocol, one is to make the information transmission confirmation of ordinary network faster, the other is to make the transmission of cross-border network break through some restrictions and solve the problem of cross-border payment in complex network environment. In this way, the transaction cycle can be greatly reced, and the whole transaction process is simpler and faster.

8. I don't think it's a good thing. We all change hands to prove that it's not safe.
