That will be a footnote at sentencing. Federal sentencing is generally based on intended or actual loss, whichever is greater. Further, the judge is allowed to take into account intended losses from his entire course of conduct, not just the intended losses from the specific counts on which he was found guilty.
In other words, the fact that his investors lost no actual money will have little bearing on his sentence. I don't know what the actual amount he took in was, but he will be sentenced for a multimillion dollar fraud scheme, and because he went to trial and lost, he'll get nowhere near the minimum. The government likes to punish people for making them expend the time and effort of a trial (in 2012, 97% of federal cases ended with a guilty plea instead of a trial [1]). He's probably looking at 5 years at best.
