Investigators said that Varshney played a major technical role in the alleged fraud. According to officials, the technological systems of the scheme were developed by Darwin Labs. These systems were: investor platforms, mining interfaces and cryptocurrency payment wallets.

The case is about an investment program called GainBitcoin. The scheme promised investors, it was claimed, monthly returns of about 10 percent in Bitcoin. As a result, thousands of individuals invested their money in the expectation that they would make big cryptocurrency profits.
However, researchers say the project never paid off its promised returns. Instead, authorities believe the organizers diverted the investor funds for other purposes. Therefore, the scheme eventually fell through when the investors did not receive payments.
Officials estimate that the money stolen in the fraud amounted to some $790 million. In local currency, the amount translates to approximately 6,606 crore Rs. The investigation hints that almost 8,000 investors were affected by the alleged scam.
Authorities said the platform was run through the company, Variabletech Pte. Ltd. According to investigators, the company orchestrated marketing and investment matters for the GainBitcoin network. As a result, the project grew over several regions, before authorities started investigating.
Investigators Link Technology Infrastructure to Fraud Scheme
The investigation goes on to say that Darwin Labs constructed the fundamental infrastructure that supported the operation. Officials said the company played a role in the development of the GainBitcoin investigator portal that participants used. Additionally, developers allegedly made the GBMiners cryptocurrency mining platform.
Authorities also targeted digital wallets which are used for the payment process. These wallets were said to process deposits and transfers related to investors funds. As a result, blockchain transaction records associated with the scheme are being investigated by the investigators.
According to investigators, the project later changed its model of payment. Instead of giving out Bitcoin gains, the operators have started their own cryptocurrency known as MCAP. Authorities say the investor funds were diverted into these tokens.
Investigators believe that this change enabled the organizers to avoid paying promised returns. Therefore, many investors are said to have received MCAP tokens, instead of real cryptocurrency profits. Officials maintain that this move helped to cover up financial losses in the system.
The arrest is a major development in the long-running investigation. Authorities have been investigating the GainBitcoin case for several years now. Moreover, the case has become one of the biggest cryptocurrency fraud investigations in India.
Law enforcement officials are still examining digital records and financial transactions associated with the network. Investigators are also looking into the technical systems used to manage accounts for investors. As a result of the above, the authorities hope to trace the flow of money through blockchain networks.
The case also raises concerns about crypto investment scams that are increasing globally. Fraud schemes often promise unusually high returns to attract investors. Therefore, enforcement actions in the area of digital asset fraud is being increased by regulators in many countries.
