You can keep going on to the next provider and so on but trading is a business. If you were contributing equity to a new business would you want to engage a supplier who would stop contributing as soon as you became profitable? Probably not.
Also, I don't agree with the notion that you should start out trading in futures CFD's because they are cheap. When you are learning anything you want as much info and as cheap as possible. With CFDS and the spread they are significantly more expensive than the underlying contract with no transparency. With the real thing you can see if there is size on the bid, offers are being lifted, bids being pulled and what size is going through where. This is the kind of stuff you need to be exposed to when learning. Not a wide spread in a derivative of a derivative.
