1. Similar to the stock exchange, blockchain exchange is the website platform for digital currency trading. Xrv522 can develop blockchain exchanges. These trading platforms generally only provide functions such as recharge, transfer and cash withdrawal. In other words, they will only tell you the collection address of your wallet, while the key, keysore and mnemonic words of your wallet will not be provided. Identity authentication is completed through login user name, password, verification email, mobile phone and other ways
(1) introction to price limit trading mode:
price limit buying / selling refers to that the user sets the price and quantity of a buying / selling currency to generate an order. The system will automatically match the buying and selling orders in the market. Once the price set by the user is reached, the transaction will be automatically executed according to the price priority time priority
(2) introction to market price transaction mode:
market price purchase refers to that the user sets a total amount and generates a commission order, from the beginning of selling to the completion of the total amount transaction. Selling at market price means that the user sets the total number of currencies to be sold, generates a commission document, and matches it from the beginning of buying to the completion of the total number of currencies transaction
(3) introction to currency transaction mode:
currency transaction is mainly aimed at the transaction between virtual digital assets and virtual digital assets, in which one currency is used as the pricing unit to purchase other currencies, and the currency transaction rule is also to complete matching transaction according to price priority and time priority< (4) introction of C2C transaction mode:
both parties of the transaction release the transaction information of buying or selling currency on the C2C transaction platform according to the demand. The buyer and the seller complete the transaction offline according to the agreed payment method, and the platform, as an intermediary, charges a certain proportion of the handling fee from each successful transaction< (5) introction to OTC OTC trading mode:
it is a set of platform for offline purchase of digital currency independent of the exchange. Businesses can publish purchase / sale advertisements on the platform, and purchase / sale users can purchase / sell through offline transfer. After the transfer, the platform will transfer the frozen digital currency to the buyer, The technical construction problems of the exchange can be found on the Internet
(6) introction to trading mining mode:
the exchange platform returns a certain proportion of the commission income to the platform users, and the platform coin is returned. According to the principle of distribution proportion, the exchange platform takes a certain proportion as the mining reward. Mining refers to trading on the platform to graally unlock the platform coin until all the platform coins are fed back. This kind of play has a strong attraction to attract users< (7) introction to futures / contract trading mode:
futures contract is an agreement that the buyer agrees to receive certain assets at a specific price after a specified period of time, and the Seller agrees to deliver certain assets at a specific price after a specified period of time. The price that both parties agree to use in future trading is called futures price. The designated r period in which both parties have to trade in the future is called the settlement date or delivery date. The assets agreed to be exchanged by both parties are called "subject matter"< (8) introction to the trading mode of perpetual contract:
perpetual contract is a new and unique contract. The goal of the contract is to allow high leverage to the market conditions of the spot market. The contract will not be delivered and can follow the reference price index through various mechanisms. The contract evolved from the traditional futures contract, but the perpetual contract has more obvious advantages and greater risks than the traditional futures contract, supporting long short two-way trading, opening a 100 times leverage, permanent position, premium and so on.

ways to purchase digital currency:
at present, digital currency is more like an investment proct. Due to the lack of a strong guarantee institution to maintain its price stability, its role as a measure of value has not yet appeared, nor can it be used as a means of payment. As an investment proct, the development of digital currency is inseparable from trading platforms, operating companies and investors
trading platforms play the role of trading agents, while some play the role of market makers. The profits of these trading platforms come from the current expenses and premium income of investors trading or holding digital currency
1. Investors need to register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time
2. Users can use the money in their cash account to buy and sell digital currency, just like buying and selling stocks and futures
3. The trading platform will sort the buying and selling requests according to the rules and start matching. If the requirements are met, the transaction will be completed
4. Due to the difference between the trading volume submitted by users, the trading request can be partially executed
take RBM operated by professional operation company opencoin as an example: ripple protocol was originally designed based on payment method, and its design idea was based on acquaintance relationship network and trust chain. Using ripple network for remittance or loan, the premise is that the payee and the payer must be friends or have common friends. Otherwise, the trust chain between users and other users cannot be established, and the transmission cannot be carried out
extended information:
the characteristics of digital currency are as follows:
1, low transaction cost
compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment of high handling charges to payment service providers
2, fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization, and it does not need any centralized organization similar to the clearing center to process data, so the transaction processing speed is faster
3, high anonymity
in addition to the physical form of currency can achieve peer-to-peer transactions without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote peer-to-peer payment, and it does not need any trusted third party as intermediary
both sides of the transaction can complete the transaction in a completely strange situation without mutual trust, so they have higher anonymity and can protect the privacy of the traders, but at the same time, they also create convenience for cyber crime, which is easy to be used by money laundering and other criminal activities
3. Hello, cloud computing power business is a business that supports users to rent computing power according to T and a certain period and enjoy corresponding income. At present, the computing power of ant's latest mining machine series on sale only supports BTC mining. The cycle is sustainable at present, and the cloud computing power procts of other cycles will be launched in the future<
purchase process:
you need to download 58coin app, or log in to the website and purchase according to the page prompts. The whole process is as follows: use usdt to purchase power procts - generate revenue the next day - release revenue on the third day, and the futures order is subject to the revenue date
cost Description:
1. Cost composition: calculation fee + electricity fee + management fee + operation and maintenance fee
2. Electricity fee: calculation power consumption * 24 hours * electricity price 0.38 yuan / kWh
3. Management fee: 6.00% of mining output is collected as management fee
4. Operation and maintenance fee: Calculation power consumption * 24 hours * operation and maintenance fee (0.07 yuan / kWh)
usdt is used to pay calculation power fee when purchasing, and electricity fee, management fee and operation and maintenance fee will be converted from daily income, In the form of BTC
income settlement:
1. Income distribution will be calculated using PPS theoretical income, and the income generated by computing power will be released to bit computing power account in the form of BTC every day
2. The estimated revenue is calculated from the actual operation of the digital asset network and will change dynamically for reference only. The theoretical revenue of the day's computing power can refer to the ant mine. After decting the electricity fee, custody fee and operation and maintenance fee, it is the daily net revenue
Proct termination:
1. Cloud computing power business with a fixed cycle will be terminated upon expiration
2. Perpetual computing power is a one-time buyout, which is theoretically held permanently. If the mining income can not cover the electricity, management, operation and maintenance costs for 90 consecutive days, the service will be terminated, and the user has no ownership of the mining machine
risk tips:
1. The price of digital assets often fluctuates greatly, and the mining difficulty of each currency will be adjusted regularly. If the currency price falls or the difficulty rises, the revenue of each mining contract will decrease. No matter from the perspective of digital assets or legal currency, this service does not guarantee that users can recover the capital. Users need to carefully assess their risk tolerance and invest in digital asset mining within acceptable risk control scope
2. Risk of force majeure and accidents: natural disasters, digital currency market crisis, war, equipment failure, communication failure, power failure, or changes in national policies and other unforeseeable, unavoidable and insurmountable force majeure events may lead to the termination of the trusteeship, the rection of investment income and even the loss of principal. The platform shall not bear any responsibility
3. The power cost and management fee may fluctuate e to the national policy, the actual situation of the mine and the change of the power cost. The platform will reserve the right to adjust the power fee and management fee.

4. In recent years, people think that the weather is getting hotter all of a sudden. The originally cool autumn doesn't begin until late October, and the hottest day in August has reached more than 40 degrees. Why? It turned out that it was human beings who caused the trouble
with the rapid development of human high technology, the side effects of science are graally reflected. Global warming is an example. Hot weather, in the heat bubble air conditioning has become a new "hobby", but people have thought, air conditioning will bring any negative impact? The answer, of course, is yes. Air conditioning emissions contain a lot of methane, which is also a gas that causes global warming. At the same time, air conditioning will waste a lot of electricity, so try to avoid using air conditioning, appropriate< Another reason is: carbon dioxide! Car exhaust and factory exhaust contain a lot of carbon dioxide, and carbon dioxide is most likely to lead to the greenhouse effect (that is, global warming). Now the number of cars is graally increasing. According to relevant statistics, by the 21st century, there are 700 million cars in the world. A lot of exhaust seriously affects us, cough, throat inflammation... The most important thing is global warming. According to statistics, the per capita carbon dioxide emission of the United States has reached 20 tons a year! China's annual carbon dioxide emissions per capita emissions are 2.51 tons a year! The environment around us is changing badly
the more important reasons are as follows: forests have been sharply reced, water resources have been destroyed, ecological chain has been seriously damaged, a large number of land is barren, and water pollution is serious. According to statistics, 10% of the world's river water has been polluted, and fresh water supply has become a problem. At the same time, e to the extensive use of minerals, the burning CO2 gas has led to air pollution, and the ozone layer has been seriously damaged, The ozone holes in the north and south poles have exacerbated the deterioration of the environment. Such a vicious circle will eventually lead to a serious impact on people's lives
what is the tragedy? Obviously! The weather is heating, sea level is rising, glaciers in the north and south poles are melting, coastal cities and island countries are flooded. All these have seriously affected the survival of human beings. Experiments have proved that sea level will rise by more than half a meter in the next 300 years, which is still the most optimistic data. In another seven years, global warming will continue irreversibly. What's more, as the Arctic ice melts and rainfall intensifies, a large amount of fresh water flows into the North Atlantic, destroying the Mexican warm current. Once the Mexican warm current is cut off, the temperature in northwest Europe will drop by as much as 5-8 degrees, which may lead to a new ice age! You must have seen the movie the day after tomorrow. The scene in the movie is just a true portrayal of our earth after hundreds of years: tornado, ice breaking, sharp drop in temperature, ice storm, freezing rain, earthquake, flood, tsunami... This is not a crazy fantasy. If human beings do not stop destroying the environment, it will become a reality! Global warming is not only a hot weather, but also a lot of negative effects
in order to save the earth, we should try our best to: do not turn on the air conditioner, use recycled environmental protection paper, abandon meat (steak) food (cow digestion contains nitrous oxide, if you become a vegetarian, the annual carbon dioxide emissions will be reced by 1.5 tons!) Do not use plastic bags, take the bus... Every bit of life. In fact, environmental protection is not difficult. As long as you support environmental protection, it is your best gift to the planet. It doesn't need too much words. As long as everyone takes action, it will be a powerful force! Today, Japan, Britain, the United States and other countries have taken action. Although we have taken action, it is not enough for a great country with a population of 1.3 billion
therefore, global warming is the only way for all mankind to save the earth. Some people may say: can we not migrate to other planets? The answer is yes, but how many people can it hold? Some people say: the funds to control the greenhouse effect are too large, which is a sky high price for finance. However, if we keep procrastinating, the final result will be that our earth is beyond recognition, not to mention finance, even our own life is hard to protect! Therefore, environmental protection should not only stay in words, but should really be paid with action!
