The promise was familiar. High returns, a known brand name, and a chance to get in early. For one investor in Thane, it ended in a police complaint, an arrest, and a dispute that now sits at the intersection of India’s fast-growing crypto market and a rising wave of online impersonation fraud.
At the centre of the case is CoinDCX, one of India’s largest cryptocurrency platforms. Its co-founders, Sumit Gupta and Neeraj Khandelwal, were taken into custody by Thane police following allegations of fraud amounting to ₹71.6 lakh. The arrests, carried out in Bengaluru and followed by court proceedings in Thane, have added a new layer of scrutiny to an industry already dealing with trust issues.
The case began with a complaint filed by a 42-year-old insurance advisor from Mumbra. According to police records, the complainant alleged that he was persuaded to invest money over several months, from August 2025 to March 2026, based on assurances of high returns. The pitch also included a franchise-style opportunity linked to a business said to be associated with CoinDCX.
The investor claims he transferred ₹71,60,015 through a mix of cash payments and online transactions. The funds, he said, were never returned. Instead, they were allegedly diverted, leading to charges of cheating and criminal breach of trust. The FIR, registered on March 16, named multiple individuals, including the two co-founders.
Police moved quickly after the complaint. A team traced Gupta and Khandelwal to Bengaluru, where they were apprehended and later brought to Thane. A local court remanded them to police custody as investigators began examining whether the case points to a wider pattern involving more victims.
For law enforcement, the immediate question is whether this was a one-off case or part of a larger network using the name of a well-known crypto exchange to attract investors. That question is not new in India’s online financial space. Fraudsters often rely on familiar brand names to build credibility before extracting money.
CoinDCX, for its part, has pushed back strongly against the allegations. The company described the FIR as false and said the case stems from impersonation. In a public statement, it said fraudsters had posed as representatives of the platform and misled investors. According to the company, the transactions described in the complaint were not connected to its systems or official channels.
The exchange pointed to what it described as a growing problem of brand misuse. It said more than 1,200 fake websites impersonating its platform had been identified and reported between April 2024 and early January 2026. That figure, if accurate, points to a steady effort by scammers to exploit the visibility of crypto platforms.
This defence introduces a second layer to the case. If impersonation is involved, the issue moves from direct fraud by company officials to misuse of identity by third parties. That distinction is not minor. It shapes how responsibility is assigned and how the case may proceed in court.
Investigators now face the task of mapping transactions, identifying accounts, and tracing where the money went. In cases involving cash and fragmented digital transfers, that process can take time. It also depends on whether the funds moved through formal financial channels or informal networks.
The case comes at a sensitive moment for India’s crypto sector. Platforms like CoinDCX have grown quickly, attracting millions of users and large volumes of trading activity. At the same time, the sector has faced repeated warnings from regulators about risks, including fraud and lack of oversight.
Trust remains a central issue. Unlike traditional banking, where institutions are tightly supervised, crypto platforms operate in a space where rules are still evolving. That gap creates opportunities not just for innovation but also for misuse. Investors often rely on brand recognition rather than detailed verification, which makes impersonation schemes more effective.
This is not the first time CoinDCX has faced trouble. In July 2025, a security breach involving malware led to a loss reported at around $44 million. The company said customer funds were not affected and covered the loss from its own reserves. Even so, the incident raised questions about internal safeguards and external threats.
The current case is different in nature but similar in its effect. It places the platform under public scrutiny and raises concerns among users about safety and accountability. For a company that claims more than 20 million users, perception matters as much as technical performance.
There is also a wider pattern at play. Across India, reports of online investment fraud have increased, often involving promises of high returns and links to known brands. In many cases, victims do not verify the authenticity of the platform or the individuals involved. Payments are made through a mix of bank transfers, digital wallets, and sometimes cash, making recovery difficult.
The role of impersonation complicates enforcement. Fraudsters can set up websites that closely resemble legitimate platforms, use similar domain names, and create communication channels that appear official. For an average investor, the difference is not always clear.
Authorities have responded with a mix of public warnings and enforcement actions. Police units in several states now track cyber fraud cases, and there have been efforts to shut down fake websites and block suspicious accounts. Yet the pace of such activity often trails the speed at which new schemes appear.
For CoinDCX, the immediate challenge is legal as well as reputational. The company has said it is cooperating with investigators. That cooperation will be tested as authorities examine records, communication trails, and any possible links between the accused and the transactions described in the complaint.
