Well, I had some nice wins in the first days, but I ran out of luck and busted all the winnings...

I blame the high fees for that, in one moment I wanted to withdraw at least something, but I didn't want to pay a 1 mBTC fee. What a degen I am, what to say. I played like crazy and made some pretty bold moves, I wanted to make even more. Anyway, I had a few crazy gambling days, maybe I will hit something really big one day.

That's natural, I've experienced the same many times

greed is hard to control and we will always find something to blame when we cant control our greed LOL.
Even if your balance is not BTC, I think you will still do the same thing and you will have nothing to blame except yourself

At least you will get something back from the contest as you are the first winner and you'll get $200.
Next time you should avoid depositing with bitcoin especially when the fee is crazy, so you will have no worry about high fee and you can withdraw your winning first.
