Your over confidence is a result of either one of two things.
One your initial judgment of me is that i'm a horrible n00b who hasn't experienced versing 'good' players before due to my lack of reputation on the site.
OR
You are simply confident cause you believe you are a great player.
I guarantee you its not the case with the first comment, and ill put up a good fight.
I have lost before, but i gave Tarek and Bjay, (only to mention those coming to the tourney) run for their money, and that was a while ago to, i'm confident that I'm prepped for the tourney enough to do 'something,' perhaps not win, but its all about fun anyway right
SO in response to your question, the answer would be no, i'm not confident enough to risk losing money, but if it WAS there, i'm pretty certain id give you a run for it, even if you did end up winning every match
I'm looking forward to versing you all!
