I set up the Weekly Hive Charity Giveaway on the @combination account to help raise money for verified registered charities on Hive by having a weekly 50-50 draw. I did it so it works fairly on verifiable rng without asking for votes or otherwise exploiting the reward pool.
I was looking into further automating it, but I got busy with other life stuff. Someone else is managing it for now so fortunately money is still being raised for charity.
I hope to get back into it more eventually. When Hive grows a lot I hope it can help charities more and more without begging for uovotes or using pooled resources.
