Introduction
Cryptocurrency is a digital form of money that operates on decentralized networks using blockchain technology. Unlike traditional currencies, cryptocurrencies are not controlled by any government or central authority. Bitcoin was the first successful Cryptocurrency, introduced in 2009, and since then, the market has expanded to thousands of digital coins.Cryptocurrency operates on a decentralized system, and at the heart of it lies blockchain technology. In India, as the number of crypto users grows, it’s important to understand how these technologies function behind the scenes. Here’s a breakdown of how crypto works in the Indian context:
Blockchain Technology
A blockchain is a digital ledger that records all cryptocurrency transactions in a secure and transparent manner. Each transaction is stored in a “block,” and these blocks are linked together in a chain — hence the name.
- Decentralized: No single entity controls it, unlike the RBI in traditional banking.
- Tamper-Proof: Once added, data in a block cannot be changed.
- Public Ledger: Anyone can verify transactions.
In India, blockchain is gaining adoption beyond crypto too — in supply chain, education, and banking.
What Is Crypto Mining?
Mining is the process of validating crypto transactions and adding them to the blockchain. It requires powerful computers and a lot of electricity.
- Bitcoin Mining: Still legal in India, but not very profitable due to high electricity costs and lack of mining-friendly laws.
- Proof of Work vs Proof of Stake: Newer coins (like Ethereum after The Merge) use less energy-intensive methods like Proof of Stake, which is better suited for Indian users and developers.
Note: Most Indian investors don’t mine — they buy crypto directly through exchanges.
Crypto Wallets in India
A wallet is used to store your cryptocurrency securely. There are two main types:
Hot Wallets (Online)
- Accessible via mobile or web apps
- Examples: Trust Wallet, MetaMask, exchange wallets (WazirX wallet)
- Good for beginners in India
Cold Wallets (Offline)
- USB-like devices not connected to the internet
- Best for large or long-term holdings
- Brands: Ledger, Trezor (can be imported to India)
Pro Tip: Always transfer large crypto amounts from Indian exchanges to your personal wallet for better safety.
How Cryptocurrency Works
Cryptocurrencies run on a technology called blockchain, a public ledger that records all transactions. Coins are either mined using computing power or issued through smart contracts. To store and use crypto, you need a wallet—either hot (online) or cold (offline).
Types of Cryptocurrencies

- Ethereum (ETH): Enables smart contracts and DApps.
- Altcoins: Litecoin (LTC), Ripple (XRP), Cardano (ADA), etc.
- Stablecoins: Pegged to fiat (e.g., USDT, USDC).
- Meme Coins: Dogecoin, Shiba Inu—popular but speculative.
Popular Cryptocurrency Exchanges
