^lol why not? Brokers are just people

though normally they are male.
As for trading, yes it's possible to make a lot of $. No, it's not easy.
You gotta understand the stock market is designed so that very rich people can take money from poorer people. I read a statistic that 90% of people who start trading quit within their first year, basically because their money goes straight to the people at the top who have inside information.
The main problem new traders face is trading emotionally, to be successful you need to a create a trading plan and stick to it, no matter what. As soon as you start getting high from profits or sad from losses then you're in trouble.
The way to be successful with stocks yourself (without trusting a broker) is being skilled at analyzing businesses, how they operate and then estimating what will happen with them in the future. This is basic stocks though, this doesn't include complex derivatives like Futures, Options etc. I've heard of people having some success with Forex (currency trading) but it is extremely volatile.
It's really confusing shit. Best way is to pick up some books explaining how it all works, if you can follow then you're doing well and might wanna give it a shot. Or you can contact some trading firms, look at their results and then trust your funds in the expert's hands. Be careful though there are a lot of shady companies out there.
