He is no different from Madoff who was sentenced to 150 years and died in jail, he should die in prison and should not taste freedom because of the many lives that were broken because of his scam.
There was a report that his lawyers wanted him to spend jail for only 5 years because of his disorder which is not fair for the victims he should spend more than 50 years, anything less than that is not fair, this is to give an example to those who wants to scam investor of their money.
