Get a few friends, create some markets for the game you all play, create a group for those markets, and get people involved on those markets.

The groups which grow to quickly have the most individual creators, good markets (with accessible criteria) and a diversity of bettors (hopefully 5+ per market) will get a bigger slice of the bounty. (About 2-3 week time horizon on the final bigger bounties)

If you try, and nobody shares your interest, I'll make sure you don't lose mana from the market creation.

I will trade on every market related to a game I play.

Most importantly!! Don't double up groups that already exist! You do not need to be the group creator to benefit here
