Usdc digital currency exchange

1. Defi, also known as open finance, refers to the financial application ecosystem created with the help of blockchain network (especially Ethereum)
users in the defi ecosystem have complete control over the assets and participate in the defi with the help of P2P network and DAPP
advantages of defi
the popularity of defi is inseparable from its unique advantages. Defi mainly includes:
1. Open loan agreement
compared with the traditional credit structure, open and decentralized loans have many advantages, including integration of digital asset lending, digital asset mortgage, real-time transaction settlement and novel secured loan methods, no credit check, standardization and interoperability. The purpose of secured lending using open protocols such as maker and Dharma is to rece the risk of counterparties without intermediation by relying on the minimum amount of collateral provided by Ethereum
2. Issuance platform and investment
famous securities issuance platforms such as polymath and harbor provide the framework, tools and resources for issuers to issue marked securities on the blockchain. They have prepared their own standardized token contracts for securities (i.e. st-20 and r-token), which are unique in terms of automatic compliance and customizable transaction parameters and can meet regulatory requirements. Similarly, they are integrated with service providers (e.g., broker dealers, custodians, legal entities, etc.) to assist issuers in issuing
3. Decentralized forecasting market
decentralized forecasting market is one of the most attractive components of open finance, which is highly complex but has great potential. August launched the anti censorship forecast market last year, and other platforms like gnosis began to follow suit. Forecasting market has long been a popular financial tool for avoiding risks and speculating on world events, and decentralized forecasting market can also do this
4 exchanges and open markets
exchanges in open finance mainly consider decentralized exchange (DEX) protocol and P2P market. First of all, DEX is a P2P asset exchange between two parties on Ethereum, in which no third party acts as an intermediary, such as coinbase or other centralized exchanges. DEX also uses some highly innovative methods to exchange tokens, such as atomic exchange and other unmanaged methods, to exchange one asset for another with minimal settlement time or risk. The most popular DAPP in Ethereum is the decentralized exchange IDEX. Although many "DEX" claim that they are indeed decentralized or unmanaged, be careful before using them. The P2P market on Ethereum has great long-term potential, and may eventually cover the market of local digital assets and marked real-world assets
5. Stable currency
stable currency is booming in the digital asset market by issuing warrants, auditing its reserves and managing its price linked new model. Stable currency is just a token issued by the blockchain, which aims to keep a stable link with external assets (mainly US dollars, gold or other assets). The stable currency of encrypted mortgage includes Maker & # 39; S Dai, where the underlying asset (e.g., ETH) is over mortgaged relative to the borrowing asset (DAI) according to the current mortgage rate. So far, stable currencies backed by legal tender are the most popular because of regulatory compliance and no audit risk, such as tether, usdc and Gemini dollars
disadvantages of defi
on the one hand, the development of defi is restricted by the performance of the underlying public chain. The current defi project is mainly built on the Ethereum network. At present, the performance bottleneck of Ethereum is relatively prominent, and there is still a long way to go to break through the bottleneck. Under such a situation, those projects with high performance requirements will be in an embarrassing situation. On the other hand, compared with traditional financial procts, decentralized financial projects are much more difficult to use and have higher cognitive requirements for users, which will also greatly affect the development speed of defi. In addition, the roller coaster like ups and downs of defi projects (sushi, yam, yfii, etc.) also make people wary of its security. How to continuously accumulate user trust is also the focus of attention in the future.

Novice first of all to know how to calculate your cost, recharge, trading, cash, there are fees. At least you can understand the K-line. There are a lot of people on the K-line. You can look at it casually and understand it. You need to be risk aware. bitcoin is a high-risk and high profit investment. It may double overnight, or BMW may become a bicycle overnight. At the beginning, we suggest a small amount of investment

but it's hard to get bitcoin for indivial mining, so it's basically large-scale mining, and you need to cooperate with the mine pool. So if you still want to make money by mining, at present, the most suitable mining method is cloud mining or mining machine hosting. After all, the era of single person mining is over

3. In online games, legal tender is game currency. All transactions of game players in the game should be completed through game currency. The role of the game company is the equivalent of the government, or, to be more exaggerated, the equivalent of God

game companies can control the economy in the game by controlling the generation of game currency (the rate of losing treasure). So, are game companies really omnipotent? The answer is No. what do game companies fear most

it is the offline transaction of players. After the players meet, they trade in RMB. I will give you money and you will give me the best equipment. In this way, they can directly skip the monitoring of the game company and affect the economic balance of the whole game

this is the reason why many online games prohibit players from trading offline, and even the game props can't be given away at all, because they are afraid that RMB trading will damage the economic system in the game

when playing the game, all players understand that the money, gold coins, diamonds, gemstones and so on in the game are essentially fake money. What is real money? It's RMB

you can only use RMB to exchange the currency in the game. The currency in the game can never be converted into RMB

you only need to understand this logic, and then replace the game company with the government

you can easily understand the essence of bitcoin. Whether it's US dollar, pound sterling or RMB, it's all issued by governments, and the government is equivalent to a game company

as long as you survive in this country, all your transactions should be completed through legal tender. However, the emergence of bitcoin is equivalent to "player offline trading". You can bypass the government and freely switch property among various countries. In the logic of bitcoin, US dollar, pound sterling and RMB become fake currencies, while bitcoin becomes real currency

the reason why bitcoin can become a real currency is that it is non renewable. There are only 21 million bitcoins, which will disappear after digging. Bitcoin, like gold, is non renewable. Whether you believe it or not, at least its logic is self consistent

but the currencies of different countries are different. As long as the government feels that it is short of money and turns on the banknote printing machine, it will be able to run full power for printing

this leads to inflation. I don't need to say anything about inflation. Comparing prices 20 years ago, 10 years ago and today, I believe everyone has his own understanding of inflation. In China, it is self-evident how much house prices have soared in the past two decades

many people buy a house not because they don't have a house to live in, but to fight against inflation. Ten thousand yuan to buy financial procts, ten years later, it will become twenty thousand yuan; Ten thousand to buy a house of one square meter, ten years later, it will become 100000 yuan

"house" was essentially "real currency" and "hard currency" before the emergence of bitcoin. The rich buy a lot of real estate to fight against inflation, but the house also has its disadvantages: first, if you really commit a crime,

the house can't be taken in your pocket, and the government should check and seal it, so there are still many risks; Second, a large number of houses are often difficult to sell, and the transaction takes a long period of time; Third, even if the house is sold, a lot of cash can not be transferred overseas. The emergence of bitcoin just perfectly solves these problems

bitcoin is installed in the hard disk. As long as you remember the password, there will be no one to check where you get it, and someone can't seal it (unless you rob your hard disk). Any fixed assets, cash need time cycle, bitcoin do not use, this second order, the next second cash to the account. Transfer assets overseas

is that true? Bitcoin was designed to bypass the monitoring of the national government and transfer assets perfectly and efficiently. Why do most ordinary people think bitcoin is useless, or even can't think of any use? Very simply,

poverty limits our imagination. As a small white-collar who works hard and earns money all his life, what assets need to be transferred? Estate tax? What's more, it's ridiculous. When people die, they just kick their legs. They never think about the need to avoid taxes on inheritance, but it's different for the rich

suppose that the inheritance tax of a certain country is 50%. Once the rich man dies, his son can only get half of his assets. However, if the rich man changes all his assets into bitcoin and gives his son the password hard disk, he will perfectly inherit it, and the government will not be able to collect any tax

(of course, this is only an ideal situation. In fact, it may not be perfect for tax avoidance, but it is still very enlightening). In addition, for law-abiding citizens, there is no risk of bankruptcy and home hunting

but for some of the top rich, they may not care about the amount of assets, but they are very concerned about the safety of assets. It's acceptable for a rich man with a fortune of 1 billion to lose 500 million in business. But what if he was robbed of his family for some inconvenient reasons? He can't accept direct bankruptcy

at this time, if he holds bitcoin, he will never be bankrupt, and no one can his bitcoin. At least we can leave some capital to make a comeback, or leave a way for future generations“ "Asset security" is what the top rich care about most, not more money but less security. To say that bitcoin can fight inflation caused by the government's printing money indiscriminately is just a good cover at this stage

only those in real need can know the real value of bitcoin and figure out its essence The ancients said: Chunjiang water warm ck prophet) this is also the most perfect function of bitcoin, which is recognized by a group of rich and anxious rich people all over the world, who are no longer willing to be controlled by the government,

or have their own blemishes in all aspects. They have reached a consensus by using bitcoin to maintain the security of their own assets by holding bitcoin together

therefore, bitcoin was not designed for the poor at first. When all living beings can understand the purpose of bitcoin, the price will not be affordable to the poor

some common mistakes about bitcoin: Q: isn't bitcoin really a Ponzi scheme? A: bitcoin is not a Ponzi scheme. Ponzi scheme needs to use the money of later generations to supplement the investors in front, and it is in the shape of a pyramid

bitcoin can be bought and sold freely, with ups and downs. If you don't buy or sell bitcoin, you can maintain the original price, which is similar to stocks. A stock can drop 90%, or even drop to delisting, can you simply say that the stock is a fraud

Q: does it make sense that bitcoin consumes a lot of power? A: it takes a lot of manpower and material resources to dig gold. What's the significance of digging gold? The power consumption of bitcoin is the same as the essence of gold mining, which expresses the recognition of its monetary attribute and its value. Q: bitcoin has no government recognition, so it has no value

also has no monetary attribute. A: the original intention of bitcoin is to fight against the government. It doesn't care whether it is recognized by the government or not. In addition, if the government breaks its promise, the currency will also be a piece of waste paper, not to mention Zimbabwe's 100 billion banknotes, and Venezuela's currency devaluation,

in terms of the bad inflation of legal currency before the liberation of our country, it was only 60 years ago. Q: what is the difference between bitcoin and tulip bubble? A: tulips are not non renewable. If they are planted, they will grow. If they are planted more, they will depreciate. There is no way to store them for a long time and cash them in time

similar foam and walnut walnut, all kinds of high-grade wood, strange stones, Tibetan mastiff... These are a way, is a bubble. There are only 21 million bitcoins, which will only be less and less

Q: the principle of bitcoin is very simple and easy to . Will it still have value? A: the principle of religion is also very simple from the perspective of modern people<

but apart from the several religions in Jerusalem, which are regarded as orthodox, what other religions have world-class influence? In fact, it's not many. You can count three to five

will modern people recognize the creation of a religion? Orthodoxy matters. It takes a long time and energy to cultivate the market

bitcoin is orthodox, authentic, the loudest and brightest brand, and the rest are niche. Q: do you think bitcoin is absolutely safe? Will hackers one day blackout bitcoin all over the world

A: This is a question of raising bar. At least for now, bitcoin is logically self consistent

you have to say that someone has broken the bitcoin system. It's like asking, "what if the aliens invade the earth tomorrow?", This possibility also exists, no one can deny, but this assumption is meaningless

Q: will there be a behind the scenes and a big dealer in bitcoin? When it rises to a certain height, it will throw everyone away

A: it may exist, but I think the probability is similar to the probability that Freemasons manipulate the world. This article is not bitcoin soft text, I did not buy bitcoin, just a simple chat about my understanding of bitcoin

I didn't buy bitcoin, and I won't recommend it to anyone

bitcoin has a great risk. The hard disk may be damaged by material resources, may be lost, and may forget the password. This risk is really great

with bitcoin jumping up and down, ordinary people may not be able to stand this fluctuation. If you want to buy it, it is suggested to look at it in a cycle of one year, three years, five years or even ten years. We should have the height and attitude of "not afraid of clouds covering our eyes", otherwise don't touch it

the stable currency usdt is a token issued by tether company based on the stable value currency USD. Tether company strictly abides by the 1:1 reserve guarantee, that is, every usdt token issued, its bank account will have a capital guarantee of USD, and users can exchange USD and TEDA at any time

1usdt = US $1, users can query funds on the tether platform to ensure transparency

use of usdt? Usdt can be said to be the intermediary carrier between digital currency and US dollar legal currency. Why do you say that? For novices, everyone is confused when they first enter the market,

buy usdt with legal currency, and then buy BTC, ETH or other currencies with usdt after a series of observation. Does this process seem familiar? There are also many contract exchanges that use usdt as contract margin

more stable currency to mainstream currency contract trading pairs appear in the options section of big exchanges. As a stable currency, its "stable" nature is reflected in the price and the consensus value it brings to us

of course, there is a price difference between inside and outside the court, let alone digital currency. So in addition to trading different digital currencies, you can also move bricks arbitrage! Brick arbitrage refers to the same commodity in different markets, there will always be different prices

as digital currency is a global asset, it is impossible for many exchanges and OTC trading platforms to have the same price at the same time

the price gap here is very small

4.

A: the connotation of stable currency

1. The stability of currency value is the ultimate goal of the central bank's monetary policy

When the price rises, the value of currency will decrease; When prices fall, the value of the currency rises

5.

Bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals

2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, And the use of cryptography design to ensure the security of all aspects of money circulation

the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

6. No
shares are in legal currency
in principle, the coin circle can buy and sell other currencies in any currency
this will lead to various currency pairs
usdt, USD, usdc, tusd and Pax can be understood as US dollar. The basic exchange rate and US dollar are 1:1, with little fluctuation
BTC / usdt. This is a bitcoin usdt pair, the bitcoin price in usdt
EOS / BTC, which is the price of EOS in BTC.

7. If it is such a demand, there is a coin Security College in coin security. You can take a good look at it. It will provide some learning resources related to blockchain and digital currency.

before okex and fire coin professional station launched usdt, bittrex, poloniex, hitbtc, coin an, Kraken, cryptopia, liqui and other platforms can trade usdt

after the currency transaction, many investors are more concerned about how to convert their tokens into legal coins. The emergence of usdt provides us with a channel to convert their tokens into legal coins

If you go out, the state is very strict
