Decrypting Cryptocurrency


Let’s tackle the first question – What is cryptocurrency?

Cryptocurrency is a form of digital currency that is generated through a process called mining. 

It is the symbiotic outcome of a Blockchain. 

It is a form of token/reward given to people who are part of the Blockchain and help verify the data i.e, Miners. 

Miners help solve highly complex mathematical problems which increase the safety of the Blockchain and every time a problem is solved, a crypto coin is generated.

Every coin in circulation has been the result of mining, there is no other way to generate a Crypto-Coin. You can only buy existing coins but no one can generate coins like how money can be printed.

This limits the total number of coins in circulation and greatly increases the Cryptocurrency value. To read more about mining read here: Investopedia

This digital currency can only be used for online transactions or for services that accept the currency. 

The question may arise in your mind, “They hand out Bitcoins and other cryptos for free just to run a few mathematical problems on your laptop?”

That however would be wildly inaccurate. Understanding the question ‘what is Cryptocurrency?’, therefore, requires an understanding of Blockchain technology.

What is Blockchain?

Blockchain is the next transformative innovation in technology that will change the way data is stored and verified. 

Every transaction in a Blockchain can be traced to its original owner, however, the identity is encrypted. Hence, it elegantly maintains transparency and privacy at the same time.

It does so by employing the services of miners who verify data and add blocks to the existing chain. 

A group of verified information makes up a block and a series of interlinked blocks make up a Blockchain.                                             

This makes sure that nothing can be falsified. If one were to falsify data on one block, they would have to do so in every subsequent block which is extremely hard (almost impossible).

This makes counterfeiting impossible as every transaction can be traced back to the individual and every mined coin can be traced to the node.

Every computer that verifies data in a Blockchain is called a node, and they are all connected through the chain. 

This means that everyone is the regulator and there is no centralized authority like a federal bank or a reserve bank. 

Mining however is no easy task as it requires computers specifically set up to solve complex computational problems. They also draw a lot of electricity. 


Hence, to successfully mine you need high-end set-ups that make the endeavour profitable.

This brings us to the question. How did it all begin? Why are Cryptos like Bitcoin and Ethereum so valuable? 

The Boom of Bitcoin

Satoshi Nakomoto is the pseudonymous/ false identity of the creator/creators of Bitcoin. They/he devised the first Bitcoin Blockchain.

Bitcoin had the advantage of being the first Cryptocurrency and hence it is the most sought after and most valuable. 

One Bitcoin is now valued at around 62,000 US dollars!

You can use bitcoins or a percentage of it for purchases online, on platforms that accept the currency. The country of El Salvador has already legalised it!

Some predict that this revolutionary currency and its concept will soon make traditional currency obsolete. 

The value of a Cryptocurrency is determined by its demand and also the value of the service provided by its Blockchain. Recently, the invention of NFTs has given rise to another valuable Crypto, let’s take a look!

Ethereum and NFTs

The next most valuable Crypto in the market currently is Ethereum. Its price has been driven up by something called NFTs. 

NFTs (Non-Fungible Tokens) are tokens that prove unique ownership online. 

These items thus become irreplicable. Like every other item on a  Blockchain, it can be traced to its origin and hence ownership can be verified.

No one can hack, steal or replicate your NFT!

NFTs can be digital artwork, songs, gifs or even physical deeds to your car, legal documents, and even tickets to a concert! 

They can be anything you can think of that is owned by you! NFTs can revolutionise how legal documentation is done.

Read more in-depth about NFTs here: Ethereum.org. Maybe you’ll be more interested if you knew that the most expensive NFT was sold for over 69 million dollars!!

There is one more Cryptocurrency that we need to talk about – Pi.

Pi – The First Mobile Phone Cryptocurrency

A pair of Stanford graduates launched what was to be the world’s first cryptocurrency that can be mined on a mobile device. 

Previously the world of cryptocurrency was only accessible to those with capital and access to high-end technology. However, Pi made it possible for users to mine on their Mobile Devices. 

Pi however is still in its infancy and currently undergoing tests. People are also worried about the legitimacy of Pi, claiming it’s just another Multi-Level Marketing scam.

All doubts aside, Pi users march on 3.5 million strong with the hope that it is indeed a valid currency. They will also be hoping for the 100$ evaluation that is predicted for a Pi coin by 2025.

If it is legitimate, then Pi will be a game-changer!

The risk/reward graph however encourages one to download the app as it doesn’t ask for any private data or bank details. You are also not asked to invest anything in it.

Let’s tackle the next biggest question surrounding crypto – Is it legal?

Legality of Cryptocurrency

The famous multi-millionaire investor/ shark of the famed show SharkTank – Mr Wonderful, Kevin O’Leary – believes that we must work with regulatory authorities and address their concerns over crypto to speed up the process of legalising it.

Experts estimate that over a Trillion dollars are waiting to hit the market if Cryptocurrencies like Bitcoin and Ethereum are legalised.

So, why is it not legalised yet, even though companies like Tesla motors and the country of El Salvador have officially recognised it as a legitimate form of payment?

Governments are afraid that it undermines the existing institutions like banks and Reserve banks. There is no regulation when it comes to the exchange of Cryptocurrency online.

Lines of credit are governed by the government to control inflation and regulate the flow of money. This however becomes impossible with bitcoin on which sanctions cannot be imposed.

The anonymity of users due to encryption also makes it a method of discreet payment for Nefarious activities. Recently 174,000 BTC was seized in the Silk Road case which was a dark web avenue for illegal drugs and arms. 

Taxing cryptocurrency is also a point of debate among policymakers.

How to use Cryptocurrency in India

Currently, according to the Supreme court order that quashed a high court ruling, Bitcoin and other Cryptocurrencies can be traded in India and financial institutions are advised to facilitate it. 

In India, cryptocurrency is not recognized as legal tender, however, it comes under the classification of gold and stocks. 

We are free to invest and trade in Crypto. Many applications allow you to do so.

Bitcoin however is taxable and read here to understand the methods: The Economic Times
