if you wanna start joining the stock market this app is great because they don't charge any fees which is awesome. I started using it this week been pretty good. Getting the hang of it still. If you use the referral link below you get a free stock and I get a free stock. It's random so we could end up with an Apple stock worth 170 dollars or a ford stock worth 8 dollars, so lets hope we get the apple stock!!
