Sam Bankman-Fried has less than a week to decide if he'll testify in his trial. If he lies, he could get a longer prison sentence.

• Sam Bankman-Fried needs to decide soon whether he'll take the witness stand in his criminal trial.
• The case is going badly for SBF, so he may think he has little to lose.
• If the judge thinks he's lying under oath, he could get an even harsher sentence.

Prosecutors are nearly done walloping Sam Bankman-Fried in court.

They're scheduled to bring just one or two more witnesses in the case, which is playing out in a federal courtroom in downtown Manhattan.

Defense attorneys have said they may not present any witnesses at all. But if they do, there's a good chance Bankman-Fried himself will take the witness stand.
