Over the years, I have bought what seems like hundreds of penny stocks. About 2/3 of the CEOs of these companies were outright scammers and the companies headed by the other 1/3 failed as a result of the vagaries of the market. I have never had a winner from any of my picks of penny stocks. I did not have the ability to let go at the right time. Lacking that ability, of course, I have never profited from such stock. So I have vowed to never buy another penny stock. They cause absolutely too much angst. Anyway, at my age I cannot afford to wait for them to mature and possibly succeed.
As the old Injun would say, "I will buy the penny stock again no more."
