The market-making arm of jailed swindler Bernard Madoffs firm is set to be sold to Castor Pollux, a Boston financial company, for $500,000 plus future payments of up to $15 million, according to a statement by a court-appointed trustee. Madoff, 70, pleaded guilty on March 12 to running the biggest investment fraud in Wall Streets history, which prosecutors have said involved as much as $65 billion.
