But freerolls give to you for free the first trainning: The patience (it's a profit). The second thing is that you can earn real money without put money in the game, you earn cents most of times, when you earn off course, but is better than losing tens of dollars maybe hundreds, then my money began to reverse his flow. Now I play cheapper games but I am satisfied because I can hit my chest and say "I am a winner player".
I am not a fan of poker game but somehow I can relate with terms of gambling and from experience with other games I know the pains you were passing through though. Initially you were thinking of becoming over night millionaire from poker but I will assume that then you didn't understand the ethics of gambling and how it works, otherwise if you knew correctly there wouldn't had been a day you would lose this big before falling back to freeroll. What I mean is that, you could have started with freeroll before finally stake money on it may be after winning some decent amount you can decide to put real money to also watch your accuracy, I think it's the lesson you learnt that brought you down to this experience.
