in SteemitCryptoAcademy3 years ago (edited)


Hello All,

As-Salaam-Alaikum ,

I am @yousafharoonkhan, your crypto professor and I am from Pakistan. And this is my 2nd class season 2 week 3.

The third lecture of our season 2 is starting from today and I will first of all try to maintain the continuity of my first lecture. In the first lecture we have tried to understand the difference between decentralized and centralized system.

While we have also seen what are the advantages and disadvantages of decentralized and centralized systems, we have also seen through the practical process how we can check which coin or blockchain which is decentralized by coding this information.

Claims to be decentralized or centralized and then we tried to understand through the question which system of business or trading people would prefer at that time and why. And in today's lecture we will read about Decentralized and Centralized Exchange and try to understand the difference between them in simple words.

So let's move on to today's lecture.

Decentralized and Centralized Exchange

Decentralized As we read in our first lecture, a decentralized system is a system in which the user is autonomous in all matters and can apply his will and decisions to his work without the permission of a middleman. Thus decentralized exchanges are such exchanges. Which give their customers complete freedom of business. The middle man does not play a role in these exchanges. Rather, you can trade your investment at any time as you wish.

If we try to understand Decentralized exchange in depth in one sentence, then it means that every person can trade on the exchange world according to his own principles. No company's rules and regulations apply to such exchanges. Decentralized exchange only connects seller and buyer and all transactions are done by the trader at will.

Centralized Now if we talk about Centralized Exchange, understand that it works on the principles contrary to Dectralized. In this the trader has to follow the rules of exchange. And those who do not follow the rules and regulations of the trader exchange may face problems in the system. In addition, the centralized exchange plays the role of middle man during trading. Thus both the seller and the buyer are operating under the principles of exchange. While we have seen that the role of middle man is zero in decentralized and this role is playing a fundamental role in centralized.

In short, centralized exchanges are exchanges in which all the assets of the trader are controlled by the exchanges. You cannot start a trade unless you have the permission required to post. We can also say that all transactions between the seller and the buyer are paid by the exchange as the middle man and all the transactions take place under the same middle man principles. And the exchanges operating under this system are called centralized exchange.

Major Difference bewteen Decentralized and Centralized exchanges

Now we try to understand the difference between the two.

Now that we understand how these two exchanges work. So now we will try to understand the difference between them and see what is the main difference between them. Which a trader should know. If we look at these two exchange there are many differences .

Verification Process The process of verifying a trader or user in a centralized exchange is very complicated. And the trader may be able to trade in centralized exchange only after his verification and verification of documents. And this stage of verification is called KYC.

While decentralized exchange does not require any kind of personal verification and trader can trade on decentralized exchange 24 hours anytime without document verification.

Trading fees There is also a significant difference in fees. In a decentralized exchange there is no fee at all which benefits the trader

whereas in a centralized exchange the trader has to pay the fees as per the rules of exchange thus charging a fee for centralized exchange trading from both the buyer and the seller. ۔

Protection of capital If everyone wants to be safe in this capital exchange, then decentralized exchange is considered safer for capital than centralized exchange. And it is impossible for a hacker to steal capital from a decentralized exchange because decentralized exchange is working on blockchain on many servers while centralized exchange works under one server. Thus this difference is also considered important.

365 Days You can trade on Decetralized and Centralized Exchange at any time of the day throughout the year. While sometimes there is an issue of Maintenance on centralized exchange due to which sometimes trading cannot take place but in decentralized there is no issue of Maintenance.

Volume If we talk about the volume of cryptocurrency, centralized exchange volume has been seen more in terms of trading. While the volume of decentralized exchange is less. So this volume plays an important role. Because during the trade, both the buyer and the seller have to trade on time and thus any coin on which the volume is high in market its means that the business is going well there .

Liquidity Now if we talk about liquidity, it has been seen that most of the buyers rush has been seen in centralized exchange and therefore the trading volume is also high. While the liquidity and volume on decentralized exchange is increasing, but since some traders do not understand decentralized exchange well, both are less.

Usability & Features If you are new, centralized exchange is very easy to use while decentralized exchange is very difficult to use. This way, if you want to do fast trading, you can do it very easily on a centralized exchange. There are many features available on centralized exchange. A trader can make short-term trades and short-term trades at will while decentralized exchange features are rare. And even more difficult to use than centralized exchange.

These are just some of the goal setting shareware that you can use. Because in order to understand any exchange, it is necessary to understand the difference between them, because unless we understand the difference, we will not be able to trade the best. And we can use both exchanges at the same time. Thus, we can only do this when we know the difference. Hopefully, you will be able to describe the basic difference between the two exchanges in your own words.

Best Cryptocurrency Exchanges of 2021

Now, in this lecture, I will talk about the best centralized exchanges in the world, because every trader wants to trade on an exchange that is easy to use and where he can find a good deal of trade. Are working But I will name only five of them on which I have my own experience, so let me tell you the names of the best exchanges.

1. Binance

The best exchange in the world is Binnance which is being used by traders all over the world in a very reliable way. And the biggest feature of this exchange is that it has all the best coins in the world listed. And the volume and liquidity of this exchange is very high. Its interface is user friendly but verification of account is very important before using this exchange. I like the binnance P2P market the most. Its spot trading is very easy and the fee is also very low. Stakeholders are also available on this exchange. If I say that this exchange can be used very easily by anyone who is just learning crypto trading, the binnance is very good.


The other most reliable exchange that I place at number two is Coinbase. The condition of the popularity of this exchange is that if any coin enters the market, if it is listed on Coinbase, the market value of this coin can be doubled. Besides, if we talk about different pairs on this market, the rest of the exchange Its trading pairs are less than that. In addition, residents of each country are not allowed to trade on this exchange. In addition, everyone can use the coinbase wallet for deposit. This exchange interface is very simple like binnance and it is also considered very reliable in terms of exchange security.


I ranked the poloniex exchange third because of the steemit coin. Because on this exchange there is a trading pair of steemit and usdt and I like usdt pair very much with steemit. While the pair of steemit on binnance is btc and etherum. poloniex friendly user. And very easy to use. The verification process is very fast and you can withdraw and deposit on this exchange only after verification.

4.Bittrex Global

Bittrex is the first exchange on which I started trading for the first time. And my dear students, you should understand that I have learned crypto trading on Bittrex exchange. And for the first time, the trade of SBD and steem started on the same exchange. If I were to say that bittrex exchange is one of the best exchanges then my claim would not be wrong. Volume and liquidity are also very high. Besides, like Binnance, its interface is very simple. This exchange is also very acceptable in terms of security. And the best coins in the world are listed on this exchange.
