Each time you claim 1 satoshi you earn activity points during few days.
You earn points when other ones claim.
Number of points won depend on your activity.
The more you claim,the more you earn point if other ones claim.
After a variable time inactivity (few days),you stop to earn points.
The member on the top (the one who has the most points) is the winner when 5000 satoshi are offered.
The points of the winner are reset to zero...
So a winner and a new commer have the same chances to earn 5000 satoshi.
If activity points are allowed:
Then you can earn uo to seven activity points.
If the system see you inactive,then you get zero activity point.
