Did you know that you can buy stocks without commission these days? In the past, you had to pay $8-30 for every order, which made buying a few shares impractical. But now there is Robinhood.
No commission, you can gamble with stocks all day long, buying as few shares as you want. A nice jolt of dopamine when your pittance goes up, adrenaline when it goes down. The catch is that they sell trading data to high frequency trading companies and maybe don't offer the best market order execution, but it is still a great deal. Get the app, check it out, and they'll give me (that's why I'm hyping it) and you a free stock (most likely a cheap one, but maybe Google or Amazon)! Happy stock market gambling!
