Everything earned by or sent to @devfund account will be used to promote Steem ecosystem development initiatives using mainly bidbots.
The vote buying process is being optimized and monitored for cost. If we notice that bid to vote value is more than about 15% on average we will consider direct transfer as donation.
Right now we believe the extra attention to these projects is worth at least a promo cost of ~15%.
While we don't really keep track we may listen and give more weight to the opinions of what should be promoted from anyone who has donated/up-voted.
