I like the creativity but I suspect it will not work.
Anker "sells" the Powerdraw products at a given level of Bucks from low to high.
I like giving Anker the freedom to offer low-bucks prizes based on higher excess inventory.
Also I think it is one person who has to manage this Powerdraw and if you insert a step you increase that individual's workload. This is a fairly light cost of Anker for the size of the community and so increasing the effort has to have a decent return for Anker in engagement. Currently the reward to Anker is getting more people involved and they trade your time for your engagement (engage, earn bucks, chance of winning). I think the way they doing it now is good. There are other competitions giveaways and active members all have won things eventually.
