Hi @papa-pepper! I am currently running a "predict the price of STEEM" contest, that is running once or twice a week. I put in 10 SBD myself everytime, and then pool increase when people upvote. You don't have to upvote, resteem or anything. You can simply just comment to participate.
The way it works is that you have to predict the price of STEEM on a specific date and time. You have to predict the price within a 5 cent range. The prediction is open for 24 hours, and the winner takes it all.
I don't demand people to upvote to participate, as I don't want to force them to anything. I am doing this because it's great fun, and it's great for the community to have these kind of contests. I think so :) You can check the contest on my blog. Thanks for making it a possibility to get sponsored!
