I thought that 1000% increase of the minimum payout was the best you could do with redeeming 3,200 reward points. And that would be much less than that what you are talking about. How have you managed to get that much? Also, is it a temporary thing for you, or will it stay like this forever? Does it depend on the Bitcoin price at the moment of claiming?
1. I have the 1000% increase activated yes.
2. It's a wagering bonus
3. It'll go, unless I keep gambling... There's probably ways to rig it so I get close to what I wagered back .
There are 2 separate bonuses. The 1000% Free BTC bonus from redeeming rewards points lasts 24hours and the other one as @jackg says is a wagering bonus. That updates continuously based on how much you wager versus how much you win from free rolls. That one can last any period of time dependant on what you do. The base reward that everything is calculated from is tied to the BTCUSD exchange rate so the total you get after applying % bonuses obviously varies as well.
