Nitrogensport had generous freerolls in poker tournaments. it is unlikely that something similar will appear, I have not yet found an alternative.
You are not reading the OP that's why you don't answer the question.
OP is looking for an alternative where he can bet at a lowest minimum,... here's the question.
Is there a website like NitrogenSports that has a smaller minimum bet? I'm looking for a sportsbook with the lowest minimum bet. Thanks.
