So I've never invested before, after a few searches I get recommended (given my preferences) to a discount brokerage site like Scottrade. Scottrade makes me nervous, the whole idea of putting my social security number into my home computer makes me nervous, and I've never done it before. Is Scottrade safe? And is it safe to put my social security number into my computer? Also is there a chain or somewhere I could go to invest in stocks face to face with a discount broker?
