I disagree. I think it will be a major factor at sentencing. First the fact that he did give them their money (with a significant return on it) back to the people well before the government got involved (meaning it wasn't a PR show) to me means there was never any intent for them to actually lose money. I think the judge will see it the same way. Because if that weren't true, he would never have repatriated the money back to pay them out. He would have just said "oops, I lost it" and continued about his regular business. As much as I dislike the guy, I do believe he didn't want to rip the people off, he wanted to try to salvage what he could to make himself look good get them their money. He just chose a deceptive, illegal manner in which to do it.

Also, harm/damage is a big consideration in sentencing. He broke the law, yes. But usually a violation of the law in this regard results in substantial losses. Because it did not here, the only damage is his violation of his contractual obligation to provide money back to those who said they wanted to cash out. By holding the money, he deprived them of their rightful property as per the contract they signed when they invested with him. And considering they would have a real hard time beating his returns, proving any sort of tort injury is essentially impossible. This leaves only the statutory violation, meaning he amazingly didn't necessarily harm anyone or their property but rather just broke the law. Given the lack of injury to the victims of his crime, I think he's likely to see a very light sentence.
