Hello everyone, you are warmly welcomed to my blog, I am here to perform Beginners' course - Task 7 --- Question > **3-) Explain in your own words what an Exchange is. Differences between a Wallet and an Exchange. Mention the advantages and disadvantages of DEX and CEX. Have you used an Exchange before? tell us about your experience**. --- ### Exchange --- Cryptocurrency exchanges (Digital Currency Exchange - DCE), are digital fora that enable their users to trade digital assets i.e cryptocurrency, either for non-crypto currencies or for different cryptocurrencies. In other words, crypto currency exchanges are online trade cottages where market prices are produced that reflect the value of cryptocurrencies based on their ration(supply) and demand. The presence of these exchange fora has enabled in last years the mass use of cryptocurrencies, being feasible to trade without main complications, non- crypto currencies for cryptocurrencies or the reverse, from anywhere in the globe, and with fairly low prices, and accordingly, more desirable than other conventional methods. Today, some trades offer among their services, the depository of crypto currencies as if they were wallets; the investment of de facto currencies with credit cards, debit cards, bank transfers or de facto(virtual) fora such as PayPal or Neteller; the (P2P), i.e., between the same users of the forum, and several ways to yield dividend beyond the speculative market. #### Types of Exchanges As blockchain technology evolves and the adoption of cryptocurrencies around the globe comes to be extra extensive, exchanges have been developing in the same way, nonetheless, they can be categorized into two major types: Centralised and Decentralised * **Centralised Exchanges**: Centralised exchanges (CCE - Centralized Cryptocurrency Exchange) are virtual trade fora that operates like conventional exchanges. A centralised exchange is acquired by the corporation that regulates it and maintains full custody over all transactions that take place on the forum. Users do not have permit to the private keys in their account, which implies that users put all their faith in the hands of the exchange operators as transactions can only be made via the mean gave and authorized by a central authority. Many of the greatly well-known centralised exchanges are: • Binance • Poloniex • Bittrex • Bitfinex • Coinbase • Kraken * **Decentralized exchanges**: --- ![Screenshot_20211228-131216_1.jpg](https://cdn.steemitimages.com/DQmWUzK7yBVqWjeeKsLz6K4AQNHMHZYoxfZX951NHqPj1pK/Screenshot_20211228-131216_1.jpg) [ Source ](https://cryptohabanero.com/2020/04/01/los-mejores-exchanges-descentralizados-para-el-comercio-de-criptomonedas/ ) --- Decentralized Exchanges(DEX) On the contrary, are not operated by a centralized authority, nor are they under the supervision of a whale. A decentralised exchange does not possess the funds, location, or keys of its users, and only performs as a routing and fitting layer for transactions that are registered on its fora. Among the vastly outstanding decentralised exchanges are: • WavesDex • Bancor Protocol • Kyber Network • EtherDelta • AirSwap • Uniswap • Justswap --- > **Differences between a Wallet and an Exchange** --- ### Wallets --- We refer to a wallet as a software that enables us to save our crypto currencies. Consequently, this is software, hardware, or paperware. We can only perform a transaction with the use of private keys in our wallets. The wallet can be divided into three crypto sectors, enabling users to communicate with a blockchain network. * Software Wallet * Hardware Wallet * Paper ware Wallet There are 2 additional wallets founded on the interface. These are, * Cold Wallet * Hot Wallet The most effortlessly available wallet is the software wallet. Users choose the wallet because it can be accessed using a computer and a mobile phone. Ex:- * Trezor wallet * Xapo wallet * Luno wallet * Trust wallet * **Hardware Wallet**: The offline wallet utilized to protect crypto assets is named a hardware wallet. Hardware wallet is the comfortable means to have access to wallets and no one is enabled to penetrate. * **Hot Wallet**: A wallet that that is operated with the use of internet is named a hot wallet. It is handily available to users when they are connected to the Internet. * **Cold Wallets**: These are offline wallets that have zero to do with the internet. Cold wallets do not permit cyber-attacks. This is achieved because private and public keys are saved offline. This is a tremendous wallet for long-term enterprises. Admission to Crypto currencies is through private and public keys. These municipal keys are fraction of the digital code selected to a decentralized blockchain and substantiate to be similar with private keys. Every transaction made is documented in the blockchain. The private keys received are to be stored in a protected place. Because if the keys are accessible by others, our crypto currencies can be stolen, hence we end up losing every token our wallets. These keys also give access to or maintain access to the wallet. This is the reason these keys are so crucial. --- **The most significant difference between a crypto wallet and an exchange** --- * (1) When we use a crypto wallet we have entire custody over our private key. And we have the only standardized key to access cryptocurrencies. So having entire control makes storage generally safer. * (2)These three major components of selling, buying, and trading are not seen in a wallet but are seen in the exchange. Exchanges can also catch sight of our private key when we grant our approval. It is not safe. It enables individual to get your key and transfer all your crypto currencies. * (3)Crypto wallet is used for long-term depository, an elevated level of safety, and comfort of use. Exchange is adequately than a wallet to conserve assets from hackers. * (4)Encryption is the particular "location" address of the blockchain that remits or receives currency. These addresses comprise of alphanumeric identities produced founded on private and public keys. * (5) The wallet is easy to use if used the exchange service often. Yet the safety is endangered because the key is preserved during the exchange. * (6) Wallet Exchange does not store user' assets. The cryptocurrency of the stored user acts as the fund trustee. It can be software, hardware, or paperware and comprises of public and private keys produced in the pattern of software or blockchain. --- > **Mention the advantages and disadvantages of DEX and CEX.** --- ![Screenshot_20211228-130124_1.jpg](https://cdn.steemitimages.com/DQmWFsYQdiwkb38V5kQhG69WTChqjDM3f6fTZbaQU22coi1/Screenshot_20211228-130124_1.jpg) [Source ]( https://blockgeeks.com/guides/decentralized-vs-centralized-exchanges/) --- ### CEX --- CEX is a centralized exchange.

A Bank account is not needed for immediate transactions from the wallet. DEX exchanges include: * Uniswap * Wavedex * Justswap * Etherdelta |Advantages|Disadvantages| |------------|------------| |According to the nature of decentralized, hacking of the network is very costly and the risk of hackers is very slim as users' money are not stored.|Dissimilar to CEX, there is no comeback choice for private and public keys, so when a user lose his keys or passwords, he miss his assets permanently, irretrievably.| |DEX system is entirely decentralized and cannot be regulated by a single individual or a mediator.|For the sake of low liquidity of DEX system, DEX's trading quantity is lower than that of the CEX.| |Marketing is performed literally from the user's wallet at low expense due to the reasonable contract functionality.|cryptocurrencies are the only currency that can be traded in DEX as fiat currencyy deposits and withdrawals are not accessible.| |Marketing has a self-regulation that enables merchants to manage or protect their keys.| --- > **Have you used an Exchange before? tell us about your experience**. --- ![IMG-20211228-WA0003_1.jpg](https://cdn.steemitimages.com/DQmYWwH26gdtKVnetiRFaPpQNabHgFfcpHqNY6t9p8hhRM8/IMG-20211228-WA0003_1.jpg) Screenshot from binance App --- There are several exchange fora as cryptocurrency is nowadays the priority of several people around the globe. though my experience with the crypto currency exchange forum is little, I have learned from my own knowledge.
