Sustainable contract development of digital currency

1. 1. digital currency contract, also known as futures contract. In short, it's business in the future. A standardized contract uniformly formulated by the exchange to deliver a certain quantity and quality at a specific time and place in the future. The vast majority of users use the margin system of futures contracts, add 10 or even 20 times leverage to leverage big funds, and then use the index fluctuation to buy low and sell high trading contracts, so as to earn double profits< 2. Perpetual contracts are derivatives. From the perspective of trading, it is similar to the traditional futures contract, but there are some differences. First of all, it has no maturity or settlement date. The perpetual swap contract is similar to a margin spot market, so its trading price is close to the underlying reference index price, which is different from the futures contract. Due to the basis, the trading price difference of the futures contract may be significantly different. Secondly, the main mechanism of anchoring spot price is capital cost< At present, rolling spot futures is the main form of perpetual contracts. Rolling contract is a kind of futures contract settled on the same day and automatically extended. Profit and loss are settled on each trading day, and the contract position held by traders will be automatically extended at the end of the trading day. In addition, the cash flow of assets will be exchanged, and the long investors will pay the capital cost to the short investors to compensate the capital cost of the short investors
3. Option contract is a kind of agreement, which can give traders the right to buy or sell assets at a predetermined price before a specific date or on a specific date. Option contracts are trading derivatives that can be based on a wide range of underlying assets, including stocks and cryptocurrencies. These contracts may also come from information such as financial indicators. Generally, option contracts are used to hedge the risk of existing positions and speculative transactions.

3. The force between nucleus and electron is Coulomb force

in vacuum, the interaction force between two static point charges Q1 and Q2 is directly proportional to the proct of Q1 and Q2, and inversely proportional to the square of the distance r between them. The direction of the interaction force is along their line, and the same sign charges repel each other, while the different sign charges attract each other

the electric quantity is Q & # 39; The Coulomb force F of the electron with the action charge of E is f = Ke * q / R ^ 2, where R is the distance from the electron to the nucleus and K is the electrostatic constant

4. Odin chain calls itself an integral part of the internal ecological cycle. "The miner is the miner". There will be no miner as a middleman to earn the price difference and rece all unnecessary losses, thus eliminating the spillover of ecological value to the third party. Although bitcoin has a flaw, the flaw is that BTC's distribution mechanism causes the whole value to flow to a third party outside the ecology. In other words, the electricity charge and mine rent of bitcoin means that all these values are outside the ecology of bitcoin. This design flaw has been filled in Odin. And Odin is a deflation mechanism, the purchase of mining machinery needs to consume Odin, so it has higher room for growth. The distribution mechanism of Odin determines that its future growth is extremely superior.

5. Headquartered in New York, the exchange is regulated by NFA and nysdfs, and is hosted by a third-party bank
pure digital currency transaction does not involve capital flow. Customers' transactions are first concted by purchasing usdt from websites or mainstream websites such as Huo coin.com
the trading procts are six mainstream currencies: BTC (bitcoin), ETH (Ethereum), XRP (reborn currency), LTC (lightcoin), EOS and BCH

6. The full name of the usdt contract is the usdt perpetual contract. At present, the 58coin exchange is the most successful one in the market<

as a whole, usdt contracts operate under the framework of perpetual contracts, so like currency based contracts, it continues to maintain the design of index mechanism, non delivery, insurance fund replenishment, 2-100 times leverage, lower handling charges, lower maintenance margin ratio and no capital cost. However, it should be emphasized that except for index mechanism and non delivery, other contracts are unique to 58 perpetual contracts, Other places may not be designed like this. Usdt contracts use usdt as the common currency for pricing, trading and settlement. That is to say, it is no longer necessary to hold BTC to make BTC perpetual contracts. As long as you hold usdt, you can trade perpetual contracts in BTC, Eth and other currencies. In fact, this design simplifies the calculation method of profit and loss, which seems more intuitive. Another point is that based on the characteristics of usdt stable currency, it has the function of bear market hedging. If you are not used to the pricing method of currency based perpetual contract and have no time to focus on the ups and downs of digital currency, then usdt contract is very suitable for you.

7. Contract trading is a kind of digital currency derivatives. Investors can get the income of the rise of digital currency price by buying long, and also get the income of the fall of digital currency price by selling short. Price close to the spot, the biggest feature is that there is no delivery date, you can hold positions indefinitely, you can also trade anytime and anywhere, there are 1-100 times to choose from. To put it simply, you can be long and short at the same time. If you think the price will fall, you can be short. If you think the price will rise, you can be short. You can make money in both directions.

usdt perpetual contract is a digital currency contract with usdt as the unit of valuation and settlement. At present, usdt perpetual contracts support the two-way trading of BTC / usdt, EOS / usdt and other contracts, and provide multiple leverage. The purpose is to allow high leverage to replicate the situation of the spot market. The contract will not be settled and can follow the reference index price of the target through the anchoring mechanism

as a pricing unit and settlement unit, usdt can trade BTC / usdt and other digital currency contracts without holding other digital currencies or only one digital currency of usdt, thus basically saying goodbye to the loss in the process of multi currency conversion. Of course, your profit is also settled in usdt. There will be only one asset in your usdt contract account< The main differences between perpetual contracts and term contracts are as follows:

- e date: each delivery contract has a fixed e date, and the delivery price is the index weighted average price one hour before delivery; The perpetual contract has no e delivery date and will never expire

- capital cost: since there is no e delivery date, perpetual contracts need to anchor the spot price through the "capital cost mechanism"

- mark price: mark price is used in perpetual contracts to calculate the unrealized profit and loss of users, effectively recing unnecessary frequent position explosion when the market fluctuates

- settlement every 8 hours: through settlement every 8 hours (04:00, 12:00 and 20:00 Hong Kong time), the unrealized profit and loss will be converted into realized profit and loss, so as to improve the flexibility of capital use

- ladder maintenance margin rate system: maintenance margin rate refers to the minimum margin rate required by the user to maintain the current position. When the margin rate is lower than the maintenance margin rate, it will trigger position explosion or forced partial rection. For users with different positions, the system of step maintenance margin rate is implemented, that is, the larger the user's position is, the higher the maintenance margin rate is, and the lower the user's optional maximum leverage ratio is

- compulsory partial closing: for users with large positions and at Level 3 or above, when the margin rate is lower than the current level maintenance margin rate, but higher than the minimum level maintenance margin rate, they will not directly blow out all their positions. The system will calculate the number of pieces needed to rece the position by two positions, and carry out partial rection. After the successful downshift, if the margin rate meets the requirements of the maintenance margin rate of the new gear, part of the position rection will stop; If it still does not meet the requirements of the margin rate of the new gear, it will continue to cycle part of the position rection process. In the warehouse by warehouse mode, in the process of compulsory partial rection, the position is frozen and cannot be operated; Under the full position mode, in the process of compulsory partial position rection, the currency account of perpetual contract is frozen and cannot be operated.
