A ponzi scheme built around a cryptocurrency is the most common crypto fraud that a majority of people fall prey to. K.V.M. Prasad, additional deputy commissioner of police, cyber crime wing, Hyderabad, says that he has handled more than a dozen cases of crypto frauds and the most common among them is luring people to invest in virtual currencies for a huge profit. He says that people do not understand what virtual currencies are, so they become vulnerable to duping. “In the majority of cases, fraudsters sell Bitcoins to people, but keep keys or code with themselves. Later, they run away with it,” he says, adding “They transfer money from a victim’s virtual wallet to their own wallets without the victim’s knowledge, as the victim has authorised them to manage their virtual wealth.”
