To change stock or sell it, you have to also have a 1.99 or you won't be able to. The only by pass I found for this is to trade out stock into other stocks that you have and then if it is over 1.99 to cash out. But they do take fees whenever you sell stock which will lower the amount that you get.
In my opinion it is not even worth it. Supposedly when you sign up and verify your account and information you were suppose to get a reward, I had this account for a year and it says "We're working on it!" meaning I probably will never see it.
I am just letting you know about coinbase so you can use it with caution and not get screwed like I did. In which I still have like .82 cent in it cause I cannot get it back when it was over 20 dollars that I invested.
Check out coinbase here. <- 10 dollars of bitcoin on me when you sign up.
