When do these assassination missions start? I invested about a mil in debonaire last night.
If you haven't started the Lester assassination missions, you are ahead of yourself. You need to sell all of that. The first investment is going to be in Betta Pharmaceuticals. Then you will invest in Debonaire on the second mission.
I found that when doing these, don't get nervous and cash out. I found that both stocks will rise to 81% profit and then sit there for a while. I would wait to cash out at that time.
