Does digital currency contract trade make money
First of all, we need to know what digital currency is. Digital currency is characterized by decentralized transaction currency. The most famous is bitcoin. However, digital currency has not been recognized by China in recent years. Recently, China plans to issue China's digital currency DCEP, or DC for short. Digital currency itself is currency. When you ask how to make money, you are actually asking, How does money make money? In fact, there are many channels. First, we will have funds in the later stage to conct private placement of digital currency. Second, how do we usually earn RMB? Now, when we promote the use of digital currency in China, we will use digital currency to earn money
as a digital currency, in fact, what China issues is similar to legal currency. The purpose of legal currency is to stabilize the RMB, which should float up and down 1:1 per second. According to different exchange rates, DCEP: usdt will float up and down 7:1. In the later stage, it may be 1:1 according to China's increasing competitiveness, which is also graally declining in recent years
as a digital currency, if you want to make money, there are many ways. Major exchanges can convert it into different digital currencies. Other digital currencies may not be as stable as usdt and DCEP, and the price will keep rising and falling according to the demand. At this time, we can buy and sell stocks in a similar way to earn the price difference, If you don't enjoy it, many digital currency exchanges provide contracts, which can buy and sell multiple times, or be bullish or bearish, or even hundreds of times at most. Many people get rich through this way, but there are also many people who lose their property. In addition, this kind of exchange will make your currency return to zero in a way, We should be wary of many such exchanges running away - refer to the second largest exchange checked OK exchange
in addition, as a national form of digital currency, there should be short positions. For example, China's state-owned enterprises carry out digital transformation to form community-based currency, which may be airdropped according to the DCEP they hold. This is my guess
in addition, defi's liquidity mining, commonly known as market making, is more popular now. In the later stage, it may replace the exchange. Everyone is an exchange and can charge a handling fee
1: do a good long-term investment plan, the best way to dig is to dig by yourself, and the best way to dig is to buy or move bricks to make money
2: if the coin is empty, choose the one with less total amount (less amount and more appreciation space), and even large enterprises will not cut the coin with less amount (because the more the coin is cut, the less it is cut)
3: if you can dig and pre dig a little, even a big company can't do something that can dig. If you can dig, you'll get nothing Pre digging is used to cut leeks, so the currency with very little pre digging should be selected.)
Four: choose decentralized wallets instead of smart contracts. More than half a year of operation (so as to ensure the stability of the wallet)
Five: check the code, operation mode and service quality of the trading platform, and choose the one with good reputation, so as to prevent the platform from being stolen and running away. At present, there are few such platforms in China, and it takes time to understand them
six: don't look at landing scenes and publicity, because only empty coins need landing scenes to attract players to buy currency appreciation (depending on the amount).

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
