My advice is to stay away unless you have money to burn. I suggest setting up a dummy account and use make believe buys and sells with any penney stock you see and see how it works out. No harm no foul that way and it will help you understand the risks without losing money. I took years of losing money and hours upon hours of watching the OTC trades by the minute before I made any money.
When I get burned out of a play, I like to go back and see how many of the Axioms punched me in the dick. Once you have these memorized, it makes your DD easy.
First lesson, the 25 Axioms has no Author. No one knows where they came from. They poped up about the time online trading first started and the masses saw the fun and gains to have. Probably the Wolf of Wallstreet, Jordan Belfort
Another worthy part of your education, below. Have your retirement investments in the S&P500 index. Play with the rest.
#1 - Preserve capital #2 - Take profits to collect a core position with low/free cost avergae, then let the runners run #3 - Selling is harder than buying, set mental price points, and be disciplined. #4 - Always sell 1/2 a position on a double. (See rule #1)
Most important - ALL stocks are POS - never fall in love with them, or their story... Take profits.
