A few hours ago, a 29-year-old bitcoin holder was kidnapped and killed in Kiev, Ukraine. Four men aged 24 to 29 were detained on suspicion of "carefully" planning to kidnap victims and steal three bitcoins worth around $207,000. "Information about the man's abduction reached the capital's police station around midnight. Residents of a house in the Solomeyang district heard screams and saw several unidentified men beating and forcibly pulling a man into a car," the police station said in a statement. A police investigation found that the attack was premeditated.
