Show answer

Answer: (B) 2 and 3 only

Answer: (b) 2 and 3 only

Let's evaluate each statement about Bitcoins:

Statement 1 is INCORRECT:

Bitcoins are NOT tracked by Central Banks.

Bitcoin is a DECENTRALIZED digital currency — its core feature is that no central authority (no government, no central bank) controls or tracks it.

Transactions are recorded on a distributed public ledger called the 'blockchain', which is maintained by a network of computers worldwide.

Statement 2 is CORRECT:

Anyone with a Bitcoin address CAN send and receive Bitcoins from anyone else with a Bitcoin address.

Bitcoin addresses are like account numbers — they are strings of alphanumeric characters.

You don't need a bank or intermediary to transact.

Statement 3 is CORRECT:

Online payments CAN be sent without either side knowing the identity of the other.

Bitcoin transactions are pseudonymous — the blockchain records the transaction between two Bitcoin addresses, but the real-world identity behind those addresses is not necessarily known.

This anonymity feature has made Bitcoin popular but also controversial.

How Bitcoin mining works:

'Miners' use powerful computers to solve complex mathematical puzzles.

When they solve a puzzle, they verify a block of transactions and add it to the blockchain, receiving new Bitcoins as a reward.

Since statements 2 and 3 are correct but 1 is wrong, the answer is (b) "2 and 3 only".

Why this was asked

Bitcoin is a decentralized digital currency that operates without any central bank or government control, using blockchain technology maintained by a global network of computers.

In 2015-16, Bitcoin gained significant media attention as its price volatility and regulatory concerns increased globally, making it a relevant current affairs topic for UPSC.

The question tests understanding of cryptocurrency fundamentals - decentralization, peer-to-peer transactions, and pseudonymous nature - which distinguishes it from traditional banking systems.

Bitcoin: Decentralized Digital Currency & Key Features

Must know

Bitcoin is a decentralized digital currency — no central bank or government controls it

Transactions happen directly between Bitcoin addresses without intermediaries

Payments are pseudonymous — real identities can remain unknown

Good to know

All transactions are recorded on a public ledger called blockchain

What is Bitcoin

Bitcoin is the world's first cryptocurrency — a digital currency that exists only in electronic form. Unlike traditional money, it operates without banks, governments, or central authorities controlling it.

Bitcoin vs Traditional Money

Feature

Bitcoin

Traditional Money

Control

Decentralized — no single authority

Centralized — controlled by central banks

Transaction Method

Direct peer-to-peer transfer

Through banks/intermediaries

Identity

Pseudonymous addresses

KYC required — full identity known

Tracking

Public blockchain but anonymous

Central bank monitoring with full details

Physical Form

Digital only

Physical cash + digital

How Bitcoin Works

Bitcoin addresses are alphanumeric strings that work like account numbers — anyone can send/receive Bitcoins using these

Blockchain is a distributed public ledger where all transactions are permanently recorded across thousands of computers

Mining involves solving complex mathematical puzzles to verify transactions and earn new Bitcoins as rewards

Wallets store private keys that prove ownership of Bitcoins — lose the key, lose the Bitcoins forever

Why This Was Asked

This 2016 question tested whether students understood Bitcoin's decentralized nature — the key trap was Statement 1 claiming central banks track Bitcoin, which contradicts its fundamental design.

Exam traps

Trap: Statement 1 — Bitcoin is NOT tracked by central banks. This is its defining feature as a decentralized currency

Common confusion: Students think 'digital currency' means 'government-controlled' — Bitcoin is digital but independent of governments

Address vs Identity: Bitcoin addresses enable transactions, but they don't reveal real-world identities (pseudonymous, not anonymous)

Blockchain Technology

Science And Technology

Blockchain: Distributed Ledger Technology Behind Bitcoin

Must know

Blockchain is a distributed public ledger that records all Bitcoin transactions

Maintained by a network of computers worldwide — no single point of control

Good to know

Each transaction block is cryptographically linked to the previous one

Immutable — once recorded, transactions cannot be altered or deleted

Core Concept

Blockchain is the technology that makes Bitcoin possible. Think of it as a digital ledger book that's copied across thousands of computers worldwide — every transaction gets recorded in all copies simultaneously.

Key Advantages

Transparency — all transactions are publicly visible on the blockchain (though identities are pseudonymous)

Security — cryptographic hashing makes it nearly impossible to alter past transactions

Decentralization — no single point of failure since the ledger exists on thousands of computers

Global Access — works 24/7 across borders without needing traditional banking infrastructure

Blockchain Structure

Each block contains transactions and is cryptographically linked to form an unalterable chain

Cryptocurrency Regulation in India

Indian Economy

India's Approach to Cryptocurrency Regulation & Policy

Must know

RBI has issued multiple warnings against cryptocurrency risks since 2013

India introduced 30% tax on crypto gains in 2022-23 budget

No outright ban but regulatory framework is still evolving

Good to know

RBI is developing Central Bank Digital Currency (CBDC) — the digital rupee

Current Status

India has taken a cautious approach to cryptocurrencies — not banning them outright but imposing high taxes and regulatory scrutiny while developing its own digital currency alternative.

Evolution of India's Crypto Policy

Year

Key Development

Impact

2018

RBI banned banks from crypto services

Crypto trading severely restricted

2020

Supreme Court overturned RBI ban

Trading resumed legally

2022

30% tax on crypto gains introduced

High tax burden on crypto profits

2022-23

Digital Rupee (CBDC) pilot launched

Government alternative to private crypto

Key Regulatory Concerns

Money laundering risks — cryptocurrencies can be used to hide illegal transactions

Tax evasion potential — difficult to track crypto holdings and gains

Financial stability — volatile crypto markets could impact banking system

Consumer protection — high volatility and technical complexity pose risks to ordinary investors

Exam traps

Current status: Crypto is legal but heavily taxed in India — not banned outright

RBI vs Government: RBI issues warnings, Government sets tax policy — different roles

CBDC vs Bitcoin: Digital Rupee is centralized government currency, Bitcoin is decentralized private currency
