April 8, 2019 - bitcoin Ponzi scheme in Korea $18m

Swindlers who used a bitcoin Ponzi scheme to rob around 56,000 people of over 21.2 billion won ($18.7 million) were arrested last Thursday.
The swindlers lured people with scant knowledge about the digital currency, mostly elderly people, housewives and retirees, with recruitment bonuses and free cryptocurrency.
