I think so
Just because you don't even pay to play, and if you play well you will win some money, doesn't matter how much, i think the more important don't push yourself to win by anyway. can you understand what i'm saying?
For example, you can play a freeroll and win few pennys, and even wether you reach in the last ones positions, after that invest your pennys in the other bet, as soon you win, you will do money without spend your own money. Do you know what that means? profit =D
best luck to you and let`s try win our first one freeroll
