Well, Now that I acutally think about it. He could have invested 5 million if Dogbert meant the 10 million was his net gain and not total sum. Carry on then.
Not to be rude or anything Infiltrator, but Dogbert said his stock tripled, not doubled. If the end result is around 10 million, and it tripled, then that means Dilbert invested between 3.3-3.5 Million, not 5.
