Crypto Regulation in India

India’s approach to cryptocurrency regulation has evolved significantly over the years. Initially, the Reserve Bank of India (RBI) issued a circular in April 2018 barring banks and financial institutions from providing services to crypto exchanges. This move created uncertainty in the industry, which was later eased when the Supreme Court of India overturned the RBI’s ban in March 2020, declaring it unconstitutional. Following this, the crypto market in India witnessed a surge in retail participation and the rise of several homegrown crypto platforms like CoinDCX, WazirX, and ZebPay. Despite this growth, the Indian government remained cautious, citing concerns related to investor protection, financial stability, and the potential misuse of crypto assets for illicit activities.

In response to rising adoption, the government introduced a tax regime for cryptocurrencies in the Union Budget 2022, imposing a 30% tax on income from virtual digital assets (VDAs) and a 1% TDS on transfers above a specified threshold. However, India is yet to formulate a comprehensive legal framework to regulate cryptocurrencies fully. The government has repeatedly emphasized the need for global cooperation in regulating digital assets. Meanwhile, the RBI continues to express concerns and is focusing on promoting the Central Bank Digital Currency (CBDC) as a safer alternative. The regulatory outlook remains cautious, awaiting clear legislative direction.

Features of Cryptocurrency

• Decentralization

Decentralization is one of the most important features of cryptocurrency. Unlike traditional currencies, cryptocurrencies are not controlled by any central bank, government, or financial institution.
