Robinhood wants to open up the world of investment to everyone. From a simple to use app to commission-free trading and fractional shares, it’s a great platform for trading whether you’re a beginner or an expert. If you have an account with Robinhood you can invite your contacts direct from the app and, should they sign up and meet the conditions of the promotion, you’ll both receive a free share with a maximum value of $200. You can keep referring friends until you’ve received a total of $500 in free stocks every year.
