In a shocking case of cyber fraud, a group of teenagers from Kolkata lost ₹2 crore in a Bitcoin mining scam in 2024. This incident highlights the growing risks associated with cryptocurrency investments, especially for inexperienced individuals enticed by the promise of quick riches. The scam, which operated under the guise of a lucrative Bitcoin mining opportunity, duped victims through social media promotions and fake investment platforms.
Cryptocurrency scams are becoming increasingly sophisticated, exploiting people’s lack of awareness and technical knowledge. This case serves as a stark reminder that while Bitcoin and blockchain technology have revolutionized finance, they have also opened the door to new forms of fraud. Let’s take a closer look at how the scam unfolded, who was behind it, and what lessons can be learned.

The scam targeted young investors who were enthusiastic about cryptocurrency but lacked proper knowledge of how Bitcoin mining works. The fraudsters used social media ads, WhatsApp groups, and Telegram channels to promote a seemingly legitimate Bitcoin mining platform. The website boasted high returns, professional graphics, and fake testimonials from supposed investors who claimed to have made massive profits.
Many of the victims were college students who had some savings or had pooled money from friends and family. They were drawn in by promises of doubling their investments in just a few months. The fraudsters even provided fake mining dashboards that displayed increasing Bitcoin balances, making the scheme appear legitimate.
The scam operated in multiple stages. Initially, victims were asked to deposit small amounts to test the platform. They received minor payouts, which built trust in the system. Encouraged by these early profits, they invested larger sums. Some even took loans or convinced their parents to invest.
However, once the total investments reached a significant amount, the scammers vanished. The website went offline, Telegram groups were deleted, and all communication channels were cut off. Panic spread among the victims as they realized they had been duped. Attempts to contact customer support went unanswered, and the fraudsters had already disappeared with the money.
After the scam was exposed, victims reported the incident to the police. Cybercrime authorities in Kolkata launched an investigation, tracking digital footprints, cryptocurrency transactions, and the fake website’s hosting details. While some suspects were identified, recovering the lost money proved challenging.
Cryptocurrency scams often involve offshore servers and anonymous transactions, making it difficult to trace the criminals. In this case, authorities suspected that an international cybercrime syndicate was behind the operation.
Victims of the scam faced financial distress, with some falling into debt due to their investments. Experts warned that scams like these will continue to rise as cryptocurrency adoption increases.

To avoid falling victim to similar scams, here are some crucial safety measures:
The ₹2 crore Bitcoin mining scam that targeted Kolkata teens in 2024 is a cautionary tale about the dangers of investing in cryptocurrency without proper knowledge. As digital assets gain popularity, scams will continue to evolve, making it essential for investors to stay vigilant.
If you or someone you know is interested in cryptocurrency, always conduct thorough research, seek expert guidance, and never trust schemes that promise guaranteed returns.
