What is OTC and should you trade it?

First, what is a stock exchange?

A stock exchange is a place where you can buy and sell stocks.
The New York Stock Exchange and Nasdaq are examples. 

But you can trade stocks that aren't listed on either.  OTC stocks are not traded on a traditional exchange, but rather but individual broker dealers. 

I own only one OTC stock, iconsumer, which you can get free stocks for here by signing up.

I also mention a competitor, honey, which you can check out here. You also can get rewards for shopping by signing up here.
