Mark will never be allowed into the US due to his drug conviction. I guess that means he is barred for life from other countries like Australia too.

I would be surprised if he managed to pay any money back to his parents.

A realistic guess would be that the money went on staff wages, office rents and costs, Lyford's personal expenses like rent and utiities etc, foolish capital investments (physical coins, out-of-date mining equipment and daft 6-monitor setups) and the greatest leak of all - paying 'profits' back to early investors.

This was a ponzi scheme all along and DeMartino was spot on with pretty much everything he said.

DeMartino completely outwitted Lyford and Lyford had no real answers to any of DeMartino's questions.

You can't get blood out of a stone, Lyford is completely broke but this whole Banx episode needs to be investigated by the relevant authorities.
