India’s largest cryptocurrency fraud has reached a turning point with the arrest of Ayush Varshney, co-founder of Darwin Labs, by the CBI. The ₹20,000 crore scam, linked to the infamous GainBitcoin scheme, allegedly involved over 29,000 Bitcoins mined and misappropriated. The arrest marks the beginning of a wider crackdown on one of the most sophisticated Ponzi schemes in India’s financial history.
Background of the Scam

Modus Operandi of the Scamsters
The scamsters used a multi-layered strategy to deceive thousands of investors:
- Ponzi Model: Early investors were paid returns using funds from new investors, creating an illusion of profitability.
- Bitcoin Mining Claims: Investors were told their money was used for large-scale mining operations, though no evidence existed.
- Network of Agents: A nationwide chain of promoters convinced people to invest, often targeting middle-class families and tech-savvy youth.
- Multiple Websites: Fraudulent portals gave legitimacy to the scheme, showing fake dashboards of “mined Bitcoins.”
- International Links: Funds were allegedly laundered through overseas companies and crypto wallets.
