A 29-year-old Bitcoin holder was kidnapped and killed in Kiev, Ukraine a few hours ago. Four men aged between 24 and 29 have been detained on suspicion of "carefully" planning the kidnapping of the victim and stealing three Bitcoins worth about $207,000. "Information about the man being kidnapped was transmitted to the capital police station at around midnight. Residents of a house in the Solomyanskyi district heard screams, saw several unidentified individuals beating and forcibly dragging a man into a car," the police said in a statement. The police investigation found that the attack was premeditated.
