India's Central Bureau of Investigation (CBI) announced the arrest of Ayush Varshney, co-founder and chief technology officer of Darwin Labs, at Mumbai airport on suspicion of involvement in the notorious GainBitcoin Ponzi scheme. Varshney was reportedly attempting to leave India at the time. Investigations revealed that the scam, operated by Variabletech Pte. Ltd., lured investors with promises of high returns on crypto investments. Law enforcement accused Darwin Labs of developing and deploying key technological infrastructure for the scam, including the MCAP crypto token and ERC-20 smart contracts. Furthermore, Darwin provided technical support for the GBMiners.com Bitcoin mining platform, Bitcoin Payment Gateway, CoinE Bank Bitcoin wallet, and the GainBitcoin investment website, platforms allegedly used to lure and defraud investors. Media reports indicate the scam began in 2015 and operated across multiple Indian states. The case is estimated to involve approximately 1.9 billion rupees (about $2.1 million) and 29,000 bitcoins. At current prices, these Bitcoins are worth over $2 billion.
