Kolkata has emerged as India’s most successful crypto investment hub this quarter, with 77.4% of investor portfolios in profit, according to CoinSwitch’s Q3 2025 edition of India’s Crypto Portfolio: How India Invests. The report, based on insights from over 2.5 crore users, highlights shifting crypto investment trends, with Gen Z (18–25) overtaking millennials as the largest investor group at 37.6%.
Kolkata ranked 6th nationally in crypto adoption but topped the profitability chart, driven by a balanced and data-led approach to digital assets. Large-cap coins dominated portfolios at 36.3%, followed by blue-chip assets (24.3%), mid-cap assets (31.9%), and small-cap tokens (7.5%), reflecting a mature strategy focused on long-term value and risk diversification.
In Kolkata, analysts note that investors in the city are increasingly combining traditional financial discipline with digital asset enthusiasm. Local traders are showing strong interest in established coins and emerging blockchain projects, signalling confidence in crypto as a parallel asset class. With rising awareness and adoption, Kolkata’s retail investors are playing a leading role in shaping India’s crypto-growth momentum.“Our data shows India’s crypto market is maturing rapidly,” said Balaji Srihari, Vice President of CoinSwitch. “Though metro cities lead today, Tier-2 and Tier-3 cities will shape the next phase.” July 2025 saw peak trading volumes, particularly on July 11 and 18, coinciding with Bitcoin’s record rally and the U.S. GENIUS Act approval. Delhi, Bengaluru, and Mumbai remained the top crypto cities, with smaller cities accelerating adoption.
