New Hobby: Playing with Options

Since I moved to the US, I haven't been doing any trades. I don't even have an account open. Since I don't have much cash and I don't like to use credit, I am not going to open a margin account but rather opt for an options account because when you're young you have nothing to lose, so I'm for taking risks.

Plus, I've never tried them. I don't even know how to exercise an option online yet.

Here are some brokerages:
