Will decentralized exchanges be listed

1. Centralized exchange and decentralized exchange have their own advantages and disadvantages, and the difference is very obvious. Let's take a look at the centralized exchange first. To put it bluntly, the trading mechanism of the centralized exchange is actually similar to our traditional stock trading
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.

2. Going to the center means that there is no country, just like bitcoin. Now the country has banned bitcoin, as you can imagine

3. First of all, the decentralized exchange mainly carries out transaction matching, asset clearing and settlement on the chain. User assets are managed by smart contracts and controlled by users. The exchange does not touch user assets
secondly, the biggest value of the decentralized exchange is that users have absolute control over their own assets, and all transaction data and records will be linked through the blockchain smart contract, so as to ensure the openness and transparency of transactions and greatly rece the trust cost of users to the exchange
thirdly, it is very difficult for hackers to steal user assets unless they can get each user's private key. Even if the exchange's private key is leaked, the user's assets cannot be transferred without the user's private key, so it is very safe. With decentralized exchanges, you no longer have to worry about the risk of losing or stealing money
for this reason, with the graal maturity of the underlying technology of blockchain, decentralized exchange has great development potential, which is the trend in the future.

4. " It's a long winter. According to the current market situation, there is a high probability that it will fall in 2019. It's almost impossible to break out. However, the instry will continue to move forward, and the decentralized exchange will continue to move forward. This is the trend of the future

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;

5. OK group's name has been changed to Oko, so it's impossible to completely decentralize, because the operation of complete decentralization can't be changed

6. Yes

7. It should be OK this year. I believe in the technology and speed of OK.

8. With the advent of the Internet of things, the number of Internet devices will increase several times. In the era of mobile Internet, mobile phones are the main networking devices, and the number of networking devices is about 4 billion. It is estimated that by 2020, the number of networking devices is expected to reach more than 25 billion. In addition, according to Alibaba cloud, the number of Internet of things connected devices will reach more than 20
billion in 2020. Overall, with the acceleration of the development of the Internet of things, the number of networking devices will be several times more than the existing mobile Internet
according to the data of the analysis report on market demand and investment opportunities of China's Internet of things instry segments issued by foresight Instry Research Institute, the scale of the global Internet of things market will reach US $200 billion in 2025; The number of Internet of things will reach billions, benefiting the whole value chain; The application of the Internet of things in various instries is deepening, giving birth to new technologies, which is concive to the transformation and upgrading of traditional instries
at present, the Internet of things application scenarios have formed a large particle (annual demand is more than 10 million) market, mainly in the fields of intelligent meter, mobile payment, smart car, smart grid and so on. Growth in these areas has led to major growth in the instry
the Internet of things extends the service scope of mobile communication, from people to people communication to things and people to things intelligent interconnection, which makes mobile communication technology penetrate into a broader instry and field. Facing 2020 and the future, mobile medical, Internet of vehicles, smart home, instrial control, environmental monitoring, etc. will promote the explosive growth of Internet of animals applications, and hundreds of billions of devices will be connected to the network to realize the real interconnection of everything;, And create an unprecedented scale of emerging instries, for mobile communications to bring infinite vitality. At the same time, massive device connections and diversified Internet of things services will also bring new technical challenges to mobile communications.

9. The precious metal exchange is only a company, and the precious metal exchange center belongs to a region including the precious metal exchange.
