So there are only 5 qualified participants so far? Means that your tournament is not attractive enough, is it? You need to make a better tournament after this one ended. You should get more and more players because 2btc as the prizepool is a good amount for a tournament.
Give a tournament where both winning and losing players may win something from it, unlike this one where only winning (profit) players can win a prize. Just my 2 cents.
Simple example: if you play one round for 0.02 btc, you got Blackjack, so you will get 0.05 btc, this is (0.05-0.02)/0.02= 150%.
BTW: instant withdrawal, I love your site.
