I'll add it in rules today. In short, each user plays their own rounds, each round costs 0.5 BTC and ROI for round 20%, so in the end of the 1st round you should get 0.6 BTC. To play next round you should pay the fee which is goes to your sponsors and to random user, to make this automatic there is option autorotation which is enabled by default. This system allows you to earn more from your referrals - each round played by referral will make you 0.25 BTC.
I must admit that I do not fully understand this explanation... the only thing I've noticed is that I've got less BTC assigned than would be expected based on my referrals.
Anyway I'd prefer not to participate in additional "rounds" with additional risk.
I thought this randomizer would work exactly like the old one, but apparently it does not...
Again my question: When will withdrawing be available?
