This would be a one time expenditure and not recurring. But as we have already done 190 ETH in sales and the DAO fund collections 2.5% in royalties from these sales we have approximately 4.75 ETH that will be distributed to the fund.
I propose to use this first round of royalty funds to sweep the GB floor and either burn them to reduce overall supply > increase relative value of all GB's.
Or hold them in a "community chest" where they can be redistributed back into the population of GB holders via whatever means we see fit. Games, giveaways, etc.
Or finally we can hold them in the DAO for future use to be decided upon with an additional proposal.
