Most people have no business getting into penny st

Most people have no business getting into penny stocks. They don't have the willpower for it and he is one. He got into it on my advise and once it lost 50% he wanted out. Now it is down to .008 and he was correct in exiting his position. Talking him back into a position is not the correct thing to do. I am risking my money but don't want to talk anybody else into investing. I have increased my position to more than cover the shares that he sold but he is not the kind of person who should invest in penny stocks. I DO want him to get his NTGL shares and think they will someday make him back the money that he lost.
