Jarryd Hayne is a convicted rapist once known for his careers in rugby league and, briefly, American football. He's serving several years in jail, after being convicted of rape, winning an appeal, being retried, and once again being found guilty.
Hayne is one of several inmates apparently convinced by the Ponzi schemer inmate, Ishan Seenar Sappidee, that he could make them massive returns. Hayne provided around AU$780,000 (~US$521,000) in Bitcoin to the enterprising inmate, who apparently amassed more than AU$2 million (~US$1.3 million)from at least seven inmates.
