This morning, the base reward dropped from 5 to 4 satoshis. The website suggests playing or buying lottery tickets to increase the reward.
So I bought 20 tickets, raised the "% achieved" from 6 to 9, but still received only 4 satoshis!
How does this work?
I'm not really sure when you will start receiving the normal base reward again. But you have to keep buying lottery tickets or continue your wagering on multiply BTC game to make it normal, and then to keep it normal. The base reward has been reduced for your low ratio of wagering to free winnings. The thing you are taking about is the additional reward progress percentage. Additional 5 satoshi (base reward amount) will be added to all the payout category if the percentage reach 100%.
