Cryptocurrency robberies become a new and disturbing trend. In Ottawa, Canada, three armed robbers broke into the office of the bitcoin-exchanger. They tied four employees, and another was hit over the head with a gun. The fifth employee from another room managed to call the police, reports Coin Fox. One of the attackers was arrested. The police are looking for the rest. “The robbers tried to force the exchanger’s employees to make a deal,” the policeman said. Last year, New Yorker Louis Meza (Louis Meza) kidnapped the Ethereum cryptocurrency almost two million dollars. In another incident in Ukraine, the head of the British crypto exchange was abducted, who was later released for a ransom of more than $2 million in bitcoins.
