And there is nothing wrong with that.
However, you are giving up the opportunity of gaining table experience (online) and knowledge of situations. (How people react to what, How you should react to what, drilling pot odds into your game, when to draw, when to not draw, when the odds of Queen high taking down the pot are good etc.)

In my opinion, the extra $100 or so dollars you may gain from folding everything pales in comparison to the knowledge you may pick up by actually playing.
Even if you were to lose $200 of your original $600 deposit, you would only be down $50, and that $50 may have been money well spent if you finally learn that A-Q is not the nuts.
