Chinese authorities have arrested all 27 major suspects of PlusToken Ponzi scheme
plus
82 "key members", i.e. the to total number arrested amounts 109 scammers who managed to fool 2 millions people. I would be interested to know their nationality. They were arrested by Chinese police, so one my assume the most of them has some roots in the area.
Perhaps the key members of this project are from China, but I think that with such a large sum of money, they have to go abroad to be safe. Hopefully there will be a detailed article about the nationality and names of these scammer, they are really talented but working in the wrong place.
