Key 4 Academy

Talking about cryptocurrencies is inevitably talking about bitcoin, so this will have to be the starting point. However, it is important to understand the additional advantages that other cryptocurrencies can have over bitcoin. This information is pertinent, as it highlights the place of other cryptocurrencies in this Universe, in addition to bitcoin and for this training has an important role to play, transmitting the knowledge base for such perception.



This course aims to transmit in a quick, simple and objective way, the essential concepts of the world of cryptocurrencies, resulting from the application of Blockchain technology and its operation in a very succinct and general way, presenting the potential and possibilities of this recent technology, O course, contains a practical component, which allows you to create a digital wallet and an account on an “Exchange”, as well as carry out the main financial transactions and transactions.

How Blockchain Works

The blockchain is so named because it consists of a series of ‘blocks’. As transactions are completed, new blocks are added to the chain. Whenever a blockchain user logs on, they receive an updated version of the ledger. The blocks serve as ‘proof’ of the completed transactions.

But as blockchain technology develops, new applications are being explored. The most important of these is known as a ‘smart contract’.

Using a smart contract, blockchain participants can cause one of a potentially infinite number of actions to occur. Smart contracts can consist of any machine-readable information, and they can be executed automatically when specified conditions are reached.

Smart contracts are currently being used for a huge variety of applications. For example, in the music industry, blockchain developers are using smart contracts to track songwriter information and make sure rightsholders are paid when their songs are used in commercial settings or played in DJ sets.

You can write virtually any logic into a smart contract. Say you’re one of those songwriters. You might specify that one of your songs can be used for adverts, but only if the advertiser fulfills certain criteria – for example, you might choose not to allow your work to be used on ads for tobacco or alcohol. Advertisers can see the specifications you’ve made, and then they can license your song automatically on the blockchain, without the need for paperwork, signatures, or even other humans.

Why Invest in Crypto?

Crypto, Cryptocurrency or digital currency such as Bitcoin is an encrypted medium of exchange based on blockchain technology, used to regulate the generation of units or coins and verify the transfer of funds. It’s a peer to peer payment system that is independent of any government or central bank. Bitcoin has been called the digital Gold as it can be used as a store of wealth and can also be used as a method of payment, currently beyond the restriction and confiscation of governments. Cryptocurrencies are located on the Blockchain which is a digital ledger of all transactions and holdings in all wallets. The blockchain is located on hundreds or thousands of computers worldwide and therefore cryptocurrency is not located in any specific country, it is everywhere and nowhere specifically.

Fast and Global

If you’ve already done a transaction with bitcoin, whether trading it for standard fiat currency through an exchange platform or simply transferred it to someone, you probably noticed that there was a small transaction fee included. For instance, if you were to send 1 BTC right now, the recipient would receive approximately 0.99996 BTC, which means around 0.0001 (BTC) went into the transaction fee.



  • A cryptocurrency is a new form of digital asset based on a network that is distributed across a large number of computers. This decentralized structure allows them to exist outside the control of governments and central authorities.
  • The word “cryptocurrency” is derived from the encryption techniques which are used to secure the network.
  • Blockchains, which are organizational methods for ensuring the integrity of transactional data, is an essential component of many cryptocurrencies.
  • Many experts believe that blockchain and related technology will disrupt many industries, including finance and law. 

Understanding Cryptocurrencies

Cryptocurrencies are systems that allow for the secure payments online which are denominated in terms of virtual “tokens,” which are represented by ledger entries internal to the system. “Crypto” refers to the various encryption algorithms and cryptographic techniques that safeguard these entries, such as elliptical curve encryption, public-private key pairs, and hashing functions.

Types of Cryptocurrency

The first blockchain-based cryptocurrency was Bitcoin, which still remains the most popular and most valuable. Today, there are thousands of alternate cryptocurrencies with various functions and specifications. Some of these are clones or forks of Bitcoin, while others are new currencies that were built from scratch.

Bitcoin was launched in 2009 by an individual or group known by the pseudonym “Satoshi Nakamoto.”1 As of Nov. 2019, there were over 18 million bitcoins in circulation with a total market value of around $146 billion.2

Some of the competing cryptocurrencies spawned by Bitcoin’s success, known as “altcoins,” include Litecoin, Peercoin, and Namecoin, as well as Ethereum, Cardano, and EOS. Today, the aggregate value of all the cryptocurrencies in existence is around $214 billion—Bitcoin currently represents more than 68% of the total value


Central to the appeal and functionality of Bitcoin and other cryptocurrencies is blockchain technology, which is used to keep an online ledger of all the transactions that have ever been conducted, thus providing a data structure for this ledger that is quite secure and is shared and agreed upon by the entire network of individual node, or computer maintaining a copy of the ledger. Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories. 

Many experts see blockchain technology as having serious potential for uses like online voting and crowdfunding, and major financial institutions such as JPMorgan Chase (JPM) see the potential to lower transaction costs by streamlining payment processing.4 However, because cryptocurrencies are virtual and are not stored on a central database, a digital cryptocurrency balance can be wiped out by the loss or destruction of a hard drive if a backup copy of the private key does not exist. At the same time, there is no central authority, government, or corporation that has access to your funds or your personal information.

Digital Currency Market Analysis

Since market prices for cryptocurrencies are based on supply and demand, the rate at which a cryptocurrency can be exchanged for another currency can fluctuate widely, since the design of many cryptocurrencies ensures a high degree of scarcity. 

Bitcoin has experienced some rapid surges and collapses in value, climbing as high as $19,000 per Bitcoin in Dec. of 2017 before dropping to around $7,000 in the following months.2 Cryptocurrencies are thus considered by some economists to be a short-lived fad or speculative bubble. 
There is concern that cryptocurrencies like Bitcoin are not rooted in any material goods. Some research, however, has identified that the cost of producing a Bitcoin, which requires an increasingly large amount of energy, is directly related to its market price.

Cryptocurrency blockchains are highly secure, but other aspects of a cryptocurrency ecosystem, including exchanges and wallets, are not immune to the threat of hacking. In Bitcoin’s 10-year history, several online exchanges have been the subject of hacking and theft, sometimes with millions of dollars worth of “coins” stolen.5

Nonetheless, many observers see potential advantages in cryptocurrencies, like the possibility of preserving value against inflation and facilitating exchange while being more easy to transport and divide than precious metals and existing outside the influence of central banks and governments.
