There is, but I can see it dwindling down after these first euphoric months of 2018, when it kinda peaked.
The biggest reason for this downturn is the price of steem IMO, which put the cap on minnows upvote power and without it other minnows and red fish are getting nothing, cause we all know too well nothing's trickling down from the top.
If this keeps going like that, only the strongest, the most established contributors will stay.
