The minimum payout is 0.005BTC but it's the total sum of all referral's earnings, not individual winnings from a specific referral.
When you cashout it deducts referral's balance from every referral, and credits your main account.
oh ok , thought it's 0.005 BTC for every single referral
it's better this way but still annoying when you refer just one referral and he is really betting small ( that's my case
)
Try referring to more people (friends, family, etc) you will see that it'll be very profitable for you.
Not only our conversion rate is very high, as also referrals will not expire from your account.
Last but not least, we share almost half of our referral's revenue with affiliates (1% of losing bets / winning bets do not carry negative rev-share)
