Christian Nieves, a New York-based social engineering scammer operating under the aliases Daytwo and PawsOnHips, defrauded over $4 million from Coinbase users by impersonating customer support representatives. He ran a small scam call center that lured victims into creating Coinbase wallets on phishing sites, enabling him to steal funds. Nieves used the stolen money to purchase luxury goods, including a Corvette emblazoned with his Instagram username, and lost most of the funds gambling at casinos. The scam primarily targeted older individuals. Authorities have traced the stolen deposits back to Nieves. Separately, a teenager has pleaded guilty to a $245 million Bitcoin heist and is reported by the government to have strong incentives to flee, highlighting ongoing challenges in cryptocurrency-related crimes.
