Cryptocurrency is an enigma. For supporters, it’s the money of the future, with the potential to replace standard currencies. On the other hand, for critics, it’s a bubble that is about to burst. 

So, which is it? And, the bigger question is – should you invest your hard-earned money in cryptocurrency? 

As Warren Buffet says, “Never invest in a business that you cannot understand.” In this guide, we walk you through the basics of cryptocurrencies – what is it, how it works, whether cryptos are a good investment so that you can make an intelligent decision after weighing all the pros and cons. 

What is cryptocurrency? 

Cryptocurrency is decentralised digital money that is designed to be used over the internet. Cryptocurrencies are not available physically. They are digital assets. 

Bitcoin, launched in 2008 by the anonymous creator Satoshi Nakamoto, is the world’s first and most popular digital currency. It remains the biggest and most widely known cryptocurrency. 

Since then thousands of other cryptocurrencies like Ethereum, Ripple, Cardano, Dogecoin, and numerous others have grown as digital alternatives to paper currencies issued by different countries.

Here are some key features of cryptocurrencies:

  • Bitcoin remains the most popular cryptocurrency, followed by Ethereum, Bitcoin Cash, Litecoin, and most recently EOS, Ripple, ZCash, Tezos and Dogecoin. Some digital currencies use the same core technology as Bitcoin, while others work using innovative technologies. 
  • The standout feature and biggest appeal of cryptocurrencies are that they are not controlled by any organisation or individual. Unlike regular paper currencies issued by various national governments, cryptos are not issued or controlled by any central authority or government. They are open-source and run on a network of computers. They are available to anyone who wants to participate. 
  • You can transfer cryptos online globally 24/7 without the need for middlemen like a payment processor or a bank. If no central authority is involved, how is cryptocurrency secure? 

This brings us to the next section, 

How do cryptocurrencies work? 

Cryptocurrencies work on a technology called the blockchain. Each cryptocurrency has its blockchain network, and the network constantly verifies and reverifies every transaction made using the cryptocurrency. 

You can think of the blockchain as a bank’s ledger or balance sheet. But, the significant difference between the bank’s ledger and the blockchain is that the blockchain is not owned by any single authority – a country, a company or a group of individuals. Anyone who wishes to participate in the blockchain can become a part of it. Also, the crypto blockchain is distributed across a digital network – making it completely decentralised. 

Let's take a closer look at the working of the blockchain:

The distributed ledger that contains records of transactions of a cryptocurrency is known as the blockchain. The blockchain comprises several individual blocks that hold information regarding transactions. The information is time stamped and linked to the previous and subsequent blocks. All participants in the blockchain network can verify the ledger, thus making it immutable and highly secure. 

The blockchain is spread across a network of computers. Each node constantly verifies the information in the blockchain. This means there is no central database, central vault or entity that can be manipulated, stolen or hacked, making the currency 100% secure. 

Why is cryptocurrency hailed as the future of money? 

Compared with traditional currencies and other assets like gold, cryptocurrencies have innovative features that make them stand apart. Here are the critical elements of cryptos that make them so popular:

  • Portability – you can transfer cryptos to anyone, anywhere in the world, 24/7, all using a mobile app or your computer. 
  • Scarcity – There is only a limited supply of cryptos in the world. This means it’s a scarce resource, which drives up its value. 
  • Security – No one authority controls cryptos. It represents a fair currency that is available for all. 

These key features make crypto supporters believe that digital currencies are the future and the best alternatives to traditional paper currencies controlled by governments and banks.
