What Is Cryptocurrency And How Does It Work?

Cryptocurrency is decentralized digital money that operates on blockchain technology and is secured by cryptography. To grasp cryptocurrency, one must understand three key concepts: blockchain, decentralization, and cryptography.

Understanding Cryptocurrency

Blockchain, in the context of cryptocurrency, is a distributed digital ledger accessible to authorized users. This ledger records transactions involving various assets, such as money, real estate, or intellectual property. Information on the blockchain is transparent, immediate, and immutable, meaning once recorded, it cannot be altered or tampered with.

Benefits Of Cryptocurrency

Unlike centralized money governed by entities like the Reserve Bank of India, cryptocurrency operates without a central authority. Decentralization in cryptocurrency means there is no single entity responsible for overseeing its value. This lack of centralization offers several advantages:

  1. Trustless Transactions: Users don’t need to trust a single governing entity, as everyone in the network has access to the same unalterable information.
  2. Data Security: Cryptocurrency transactions are highly secure. Shared ownership ensures all users validate the accuracy of data, minimizing the risk of data mismanagement or miscommunication.
  3. Cryptography: Cryptography plays a crucial role in securing data from unauthorized access through encryption techniques. Features like privacy and immutability in blockchain are enabled through cryptography.

History Of Cryptocurrency

The roots of cryptocurrency technology date back to the 1980s with the development of a “blinding algorithm” for secure digital transactions. In 2008, a group under the pseudonym Satoshi Nakamoto introduced Bitcoin, the first and leading cryptocurrency. Despite its launch in 2009, it took years for Bitcoin to gain recognition as a payment method among major merchants, starting with WordPress in 2012.

How Cryptocurrency Works

Cryptocurrencies operate independently of government or central regulatory authorities. They function outside the traditional banking system and are represented by various coins, with Bitcoin being the most prominent.

  1. Mining: Cryptocurrencies are generated through mining, a process where miners use specialized computer systems to solve mathematical puzzles and earn bitcoins as rewards. However, mining a single bitcoin can take around 30 days.
  2. Buying, Selling, and Storing: Users can buy cryptocurrencies from exchanges, brokers, or individual owners and store them in digital wallets. Wallets can be “hot” (connected to the internet for easy transactions but vulnerable to theft) or “cold” (offline for enhanced security but less convenient for transactions).
  3. Transacting or Investing: Cryptocurrencies can be easily transferred between digital wallets using smartphones. Users can use them for purchases, trading, or exchanging them for cash through various platforms and methods.

Types Of Cryptocurrencies

There are thousands of cryptocurrencies available, including Bitcoin, Altcoins (alternative digital currencies to Bitcoin, like Ethereum), and Crypto tokens. These vary in mining capability, blockchain association, and utility in purchasing products or services.

Should You Invest In Cryptocurrency?

While cryptocurrencies offer advantages like privacy, security, and transparency, they also pose risks:

  1. New Concept: Cryptocurrencies are relatively new, and their long-term sustainability is uncertain.
  2. High Risk: The volatile nature of cryptocurrencies makes them prone to sharp fluctuations, posing risks to investors.
  3. Legality: Cryptocurrencies are banned or restricted in several countries, affecting their value and legality.
  4. Scalability Issues: Blockchain’s slow transaction speed can make cryptocurrency payments less efficient compared to traditional electronic payment methods.

Cryptocurrency In India

The status of cryptocurrency in India was uncertain until the 2022 Union Budget announcement, which included a 30% tax on gains from the transfer of virtual digital assets. This sparked debate on the government’s stance on cryptocurrency, with speculations of a potential ban on private cryptocurrencies following the RBI’s introduction of its official digital currency.


Cryptocurrency’s future remains uncertain, and investing in it requires thorough research and caution. While it presents opportunities for profit, it also carries significant risks. If you decide to invest, start with leading cryptocurrencies like Bitcoin, use authorized platforms, and diversify your investments to minimize risks. Understanding your country’s policies on cryptocurrency is crucial, and seeking expert advice can help navigate this complex investment landscape.
