I finished the game and want to invest my millions but I have already completed the Lester missions so I can't use that easy method to make big gains on the stock market.
So I looked at destroying rival company vehicles of specific companies but that really doesn't seem to be working? I invested into the rival of USFly and then destroyed loads of USFly vehicles but the price didn't change at all over the next 2 days. I also invested in Lifeinvader when they were at $3 since the graph shown that they were going up and down in the week with a high of $50. However, the stock only fluctuated by a couple of cents over an ingame week yet the graph still showed it as going up and down which made zero sense whatsoever.
I kept track of other stocks too and none seem to be changing drastically. Anyone else had this problem?
