Robinhood App For Trading Stocks

Has anyone else in here used this app? I just started and it seems pretty awesome and trading is free but I'm pretty green with this kind of stuff so I thought I would see if there are any opinions out there. From the reviews it seems the only downside is somewhat slow withdraw times but I don't think that's something that bothers me too much.

 

I have not used it but, I sure like the sound of it... Looks like they will start making cash (other than interest) when they begin margin trading so seems to be a good deal as long as you know what you want to invest in.

 

I was wondering how they were making money off of this without any ads. Definitely seems like a good tool
Well I guess you move up in line for instant deposits with referrals... Not really important to me but if anyone wants to use this link to sign up I would appreciate it

Revisiting this thread. So just to clarify, if you DON'T have robinhood instant it takes 3 days to settle your funds after you sell a stock... Still free, just can't use your money for 3 days after you sell. So the referrals are actually more important than I had originally thought. If anyone sees this and wants to start using Robinhood, help a brotha out and use the above link. The more referrals you have the better chance you have of getting robinhood instant. Thanks!
