A man in Hong Kong caused a scene when he threw bank notes from the roof of a building. Wong Ching-Kit is a cryptocurrency promoter, also known as "Coin Young Master." He threw cash to the wind in a publicity stunt this weekend. Some media sources estimated he dropped as much as $25,000 onto the streets of one of Hong Kong's poorest neighborhoods. The next day, Wong returned to the scene in a sports car, reportedly to give out more money. But he was taken away by Hong Kong police.
