Decentralized exchange is blocked
the first step is to register (open an account) and set the password. The second step is user authentication (KYC). The third step is to recharge. Here comes the key. The third step is the most important. Because you need to charge money to your address in the exchange before you can trade money in the exchange. The address of the exchange is actually a wallet address, but the ownership of the wallet is not the user, but the exchange, that is to say, the private key of the address, you don't have it!!! Do you understand the meaning
well, after recharging, the transaction is finished. The user submits the instruction (hanging order) to the server, and then the exchange will be responsible for matching the transaction, which is exactly the same as the stock. The last is cash withdrawal (withdrawal of currency). Users can send instructions to transfer the currency from the exchange address to their wallet address. The above is the trading mechanism of the centralized exchange. In these steps, all actions will have costs. No matter you recharge, trade or withdraw money, gas and handling charges can't escape
then let's look at the decentralized exchange. The trading mechanism is different from the centralized exchange. The first step is to register (open an account) and set the password. It doesn't make any difference. But then it's a little different. KYC is not used. But because there is a private key, the ownership of this address is completely controlled by the user. The second step is recharging. This is not very different from the centralized exchange. You still have to make your own gas
after recharging, we can also trade in the decentralized exchange. Users can also register orders, and exchanges will also be responsible for matching transactions, but the matching is done by smart contracts. Finally, cash withdrawal (withdrawal of currency) is initiated. After withdrawing currency, users can directly transfer the currency from the address of the exchange to their wallet address. This step is the same as that of the centralized exchange
the above is the trading mechanism of centralized and decentralized exchanges, and the difference between them is also obvious. Because all currencies in the central exchange are under its control, the trading efficiency is very high, and it is similar to the stock trading process, convenient and suitable for most users. Conversely, the risk lies in this. If the exchange itself loses its integrity or is attacked by hackers, the user's capital (currency) is not guaranteed
all the transaction processes of decentralized exchanges are completed by smart contracts, so the transaction efficiency is relatively low (TPS of blockchain technology has always been a soft rib), but relatively, the capital (currency) is completely in the hands of users, so the security is relatively high. In addition, there are also KYC, where KYC is needed for centralization, but not for decentralization, and the security of personal information is relatively high. Compared with the decentralized exchange, the advantages of the centralized exchange lie in the trading depth and the number of users, which are unmatched by the decentralized exchange
therefore, centralization and decentralization have their own advantages and disadvantages. It depends on the user's own choice. They like convenient, centralized, secure and decentralized.
one of the core advantages of decentralized trading is to avoid any assets being entrusted. You have absolute ownership and control over your own assets. The possibility of asset theft is extremely low, which greatly reces the trust cost of users on the exchange
from another point of view, with the implementation of blockchain applications, we have more and more digital assets at the same time, and we need to pay different tokens when using services. In this case, cross currency trading will become more and more frequent, and the process of realizing this transaction needs to rely on the mechanism of decentralized exchange
therefore, the decentralized exchange will have a bright future. Among all the decentralized exchanges, whaleex is my favorite. It not only has fast trading speed, but also does a very good job in security performance. Among all the exchanges at present, I think it is the best one. I don't have to worry about stealing or losing money when I put money in it. Their smart contracts are through security audit, and they will also support cross chain and legal currency OTC. If they grow up in this bear market, they will be a giant. I am very optimistic about its prospects& quot;
x protocol: a point-to-point open protocol running on Ethereum. The protocol aims to become a general open standard, as a basic mole that can be combined with other protocols to drive more and more complex blockchain applications. However, Ethereum is famous for its congestion, so its current situation is not very good

Road printing protocol: decentralized transaction protocol of class X. The on chain smart contract is responsible for asset custody, matching and transaction, and the off chain smart contract is responsible for order matching. It has an on chain trading loop matching technology, which encourages the exchange to match the transaction path with the maximum discount, so as to save transaction costs for users and make the exchange profitable at the same time. But on the other hand, it also increases the complexity of smart contract and the execution cost of Ethereum transaction, and the effect in practical application remains to be seen
there are also kyber, idex, bitstocks, etc. decentralized exchanges are the trend in the future, so there are still quite a few in the market. But comparatively speaking, I still think whaleex is the most reliable.
No
all transactions of European Union are virtual currency transactions
in a decentralized exchange, users' assets are directly held in their wallets, which greatly reces the risk of loss of users' assets caused by theft or running away from the exchange. Matchmaking transactions completed through smart contracts and settlement and clearing completed on the chain not only enhance transparency, but also greatly rece dependence on central media
decentralized exchanges include all the decentralized value and asset exchange methods. Due to the lack of trust, in many existing trading scenarios, various forms of centralized exchanges are needed to provide trust guarantee, and blockchain technology will rece the cost of trust by building shapeless decentralized exchanges, Graally reshape the old value exchange system
extended materials:
precautions:
1. The real holder of digital assets is the user himself. He has absolute ownership and control over his own digital assets. He will not lose his own assets e to the theft of the exchange, which ensures the security of digital assets
2. Through open source smart contracts, asset custody, matchmaking and asset clearing are all put on the blockchain
3. Using smart contract to realize the trading mechanism of decentralization and distrust solves the internal operational risk, business moral risk, asset embezzlement and other risks that seriously affect the user's asset security caused by human factors in the centralized exchange
4. Because the user's account key is controlled in their own hands, the hacker attack is technically changed from centralized attack to decentralized attack on personal accounts, resulting in the decline of profit margin and the improvement of relative security

e to the need to link transaction data and wait for miners to pack and broadcast transaction confirmation, the transaction speed of decentralized transaction is slow. The operation steps of decentralized trading platform are relatively complex, and the use threshold is higher. When it comes to the transaction of different blockchain assets, such as bitcoin and Ethereum, it needs more complex cross chain technology, and many decentralized trading platforms can't realize it, so the supported transactions are less than the centralized trading platform

The K-line, also known as Yin Yang candle, is said to have originated in the rice market of Japan in the 18th century. At that time, Japanese rice merchants used it to express the change of rice price. Later, it was quoted into the stock market and became a theory of stock technical analysis. K line is a columnar line, which is composed of shadow line and entity. The part of shadow line above the entity is called up shadow line, and the part below is called down shadow line. The entity is divided into positive line and negative line. Among them, the shadow line indicates the highest and lowest trading price of the day, while the entity indicates the opening and closing prices of the day
