New Delhi/Mumbai: In a major development in one of India’s largest cryptocurrency fraud cases, investigative agencies have arrested tech expert Ayush Varshney, a Forbes 30 Under 30 Asia 2018 honoree, in connection with the GainBitcoin scam. He was detained at Mumbai airport while allegedly attempting to leave the country. The arrest is being seen as a significant breakthrough in the ₹17,000 crore (approximately $2.1 billion) fraud that has impacted over 100,000 investors across the country.
Airport Arrest Sends Shockwaves Through India’s Biggest Crypto Fraud Case
The GainBitcoin scheme was launched in 2015 by Amit Bhardwaj and Ajay Bhardwaj. It operated under the guise of a cloud mining model, promising investors returns of nearly 10% per month for 18 months—figures far higher than realistic crypto mining yields. The promise of assured and high returns drew massive participation, especially after India’s 2016 demonetization, when interest in digital currencies surged amid limited regulatory oversight.
80,000 BTC Trail Puts GainBitcoin’s Tech Backbone Under Fresh Scanner
Investigations have revealed that nearly 80,000 Bitcoins (BTC) were collected through the scheme, making it one of the largest crypto-linked frauds in India. The model also incorporated a referral system, offering commissions of up to 12% for onboarding new investors. This structure effectively turned it into a Ponzi or pyramid scheme, where funds from new investors were used to pay earlier participants.
According to investigators, Ayush Varshney played a key role in developing the technological backbone of the operation. His company, Darwin Labs, is alleged to have built the user interface, mining platform, and MCAP token ecosystem that facilitated investor onboarding and fund management.

However, the defence has argued that Varshney was merely a technical developer and had no direct involvement in the financial operations or handling of investor funds. It maintains that the scheme’s core operations were managed by Amit Bhardwaj and his associates. Notably, Amit Bhardwaj, considered a key figure in the case, is now deceased.
Investigating agencies have rejected this claim, stating that the accused did not cooperate during interrogation and withheld crucial information regarding co-accused individuals and the whereabouts of the defrauded crypto assets. Officials say tracing the digital transaction trail remains the most complex and critical aspect of the investigation.
The probe gained further momentum following a Supreme Court directive in December 2023, which led to coordinated raids at more than 60 locations across the country. During these operations, authorities seized cryptocurrencies valued at approximately $2.59 million, along with significant digital evidence, including servers, crypto wallets, and transaction logs.
Court Grants Bail, But Investigators Say Key Questions Still Unanswered
Despite the gravity of the allegations, a Delhi court granted bail to Varshney on April 7, observing that there was no direct evidence at this stage to establish that he personally received or controlled investor funds. The ruling has added complexity to the case, particularly in determining accountability in technology-driven financial frauds.
The case once again highlights the risks associated with unregulated cryptocurrency investment schemes. Experts have consistently warned that models promising unusually high, fixed returns often resemble Ponzi schemes.
At present, agencies are focusing on uncovering the full extent of the network, identifying other key players, and tracing cross-border fund flows. With thousands of investors awaiting clarity and justice, further revelations are expected in the coming weeks, which could significantly influence the regulatory approach toward cryptocurrency investments in India.
