This thread has become a little long, so I don't know if someone said this already.
I foresee that there will be 3 types of players, the Hardcore, The weekend Warriors, and the absolute casuals.
A multiple daily reward will surely help the community gain that sudden influx of BFP to kickstart the economy, however I think that the reward system should perhaps be split into tiers to help even it out for those who simply cannot play daily. Another problem is that you are cultivating a system of bots, where players would create 20+ accounts and grind hours to generate the passive income.
