It is a great pleasure to be once again in this fourth season of the Steemit Crypto Academy, and a warm greeting to all participants, both those who have been present in previous seasons, as well as those who have just joined this initiative, which seeks to encourage knowledge of this fascinating universe through study and research.

Last two seasons, we had the opportunity to talk in depth about fundraising processes for the development of new projects based on blockchain technology, the requirements that any good business plan must meet to be attractive to the interests of investors and crypto enthusiasts, and the various tools offered by Technical Analysis to study the crypto-asset market and predict with some degree of certainty the future behavior of prices.

We were also exceptional witnesses, being able to see how the news and opinions of well-known public figures can generate an upward or downward trend in the prices of the main cryptoassets in the various markets; and finally, we were able to learn about various investment alternatives that currently exist, with the aim of generating returns with our crypto portfolio.

In this new season, we will have the opportunity to learn about the the various applications that blockchain technology has in practically all areas of human endeavor, beyond serving as a platform for crypto assets, including those platforms called exchanges or exchange houses, and the mechanisms for the purchase, sale or exchange of our virtual currencies, making use of our funds in fiat money or through our cryptocurrencies and tokens, and the multiple options offered by the current market.

Once again, I reiterate my pleasure and my deepest gratitude for the trust placed in me, to be again at the helm of this new season of the Academy that has just started this week.

As blockchain technology evolves and the adoption of cryptocurrencies around the world becomes more widespread, exchanges have been evolving in the same way, however, they can be classified into two main types: Centralised and Decentralised

Centralised Exchanges

Centralised exchanges (CCE - Centralized Cryptocurrency Exchange) are virtual exchange platforms that function like traditional exchanges.

A centralised exchange is owned by the company that operates it and maintains full control over all transactions that take place on the platform. Users do not have access to the private keys in their account, which means that users place all their trust in the hands of the exchange operators as transactions can only be made through the mechanisms provided and approved by a central authority.

Some of the most well-known centralised exchanges are:

• Binance
• Poloniex
• Bittrex
• Bitfinex
• Coinbase
• Kraken

Binance is currently the largest exchange

On the other hand, decentralised exchanges (DEX - Decentralized Cryptocurrency Exchange) are not operated by any one company, nor are they under the supervision of a single authority as they make use of blockchain technology, just like cryptocurrencies.

A decentralised exchange does not retain the funds, location or information of its users, and only serves as a routing and matching layer for transacting orders that are registered on its platforms.

Decentralised exchanges are a consequence of the evolution of traditional exchanges. Their operation is very similar to that of the latter, but they operate in a decentralised manner, which means that there are no intermediaries, and the operation of the platform is self-sustained by its programming.

Among the most popular decentralised exchanges are:

• WavesDex
• Bancor Protocol
• Kyber Network
• EtherDelta
• AirSwap
• Uniswap
• Justswap

• Transaction volume: centralised exchanges have a higher volume of transactions than decentralised exchanges.

• Liquidity: Centralised exchanges have greater liquidity.

• Security: Decentralised exchanges, by using blockchain technology, have a lower level of risk compared to centralised exchanges, and are therefore more difficult to hack.

• Anonymity: centralised platforms require users to register an account, for which they must provide personal information that usually includes their physical location, bank accounts, personal photograph and identity documents, unlike decentralised exchanges that preserve the anonymity of their users.

• FIAT money and cryptocurrencies: many centralised exchanges allow buying and selling of cryptoassets with fiat money, accepting credit cards, debit cards, bank transfers and digital payment platforms such as PayPal. In contrast, decentralised exchanges only allow cryptocurrency transactions.

• Speed: transaction times on centralised platforms are shorter.

• Transparency: Most centralised exchanges publish information regarding their owners and location of their physical offices, while a decentralised exchange rarely provides any physical address and seeks to anonymise its users.
