I did a rough economic analysis of what it costs to cheat here: POOL pool Jackpots - #9 by ageless
I voted unsure because while I would like to get behind this idea, it seems impossible to eradicate any cheating from any design proposed. It’s a matter of how can you minimise cheating to deploy the concept in the best case. And minimising cheating might come at big costs like having an unattractive prize each week.
Seems like introducing some sort of time requirement might help. But ultimately I haven’t seen a satisfactory spec proposed to date that I think won’t be chronically gamed.
