I champion this idea because there is little incentive for users to stick with PrimeDice when a 'better' offer comes around. I've also been a part of the PrimeDice campaign for around six months, sticking through thick and thin. Yet some fair weather user can waltz on in and receive the same rate as me, despite them selling out PrimeDice in the past.
If there were a coefficient that could be applied to the final payout then that would be nice, for instance:
1 x new to two months
1.1 x two to three months
1.2 x three to five months
1.3 x six to 12 months
1.5 x 12 months +
Okay so I just plucked the coefficients out of the air, they aren't based on anything around profit and loss etc. But the principle is that people will think twice, perhaps thrice times before selling out PrimeDice for another, higher paying offer in future.
Maybe it needs to be considered as consistent payouts - Stunna will keep a record of who has payouts, you can then identify who has two months of payouts at-a-glance.
It is extra work, but what it means is that people think twice before moving. I suppose you could say "but what is to stop other campaigns from implementing the same mechanism?"
