If you got more referrals then it is fine but never try to play this hi-low game on this game because this site got a high house edge and you may lose more than what you're aiming at the end. But if you can manage to get active referrals then you can make some good passive income from this site.
Actually, if you count in all the free extras, reward points, lottery tickets and bonuses it cancels out the higher house edge. I'm doing pretty well with the hi-lo game.
Active referrals are obviously the risk free way to make on the site and I've been lucky enough that about 20 of mine are still going every day after 4 years!
